    Introduction Burkitt's lymphoma is a highly malignant, aggressive and rapidly growing B-cell neoplasm, which has low long-term survival rates. The abdomen is the most frequent onset site of non endemic Burkitt's lymphoma. Symptoms are often misleading and make diagnosis difficult. Ileum intussusception as acute abdomen caused by Burkitt lymphoma is rare. Case presentation We are presenting a case of a 16 year-old male with acute abdomen, which three weeks prior initially has been surgically t...

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

    Full Text Available Burkitt's lymphoma is an extremely aggressive B-cell non-Hodgkin lymphoma. Patients with the sporadic form of Burkitt's lymphoma typically present with a rapidly growing abdominal mass, pain and distension. Involvement of either the appendix and/or ovaries in females is a rare manifestation of the disease. We present an unusual case of a 13 year old girl with appendiceal and ovarian Burkitt's lymphoma presenting with signs of acute appendicitis. This case demonstrates the potential for secondary involvement of the appendix and/or ovaries from Burkitt's lymphoma as well as the importance of the histopathology.

    Full Text Available BACKGROUND: Burkitt lymphoma, a childhood cancer common in parts of sub-Saharan Africa, has been associated with Epstein Barr Virus (EBV and malaria, but its association with human immunodeficiency virus (HIV is not clear. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a case-control study of Burkitt lymphoma among children (aged < or = 15 years admitted to the pediatric oncology unit in Blantyre, Malawi between July 2005 and July 2006. Cases were 148 children diagnosed with Burkitt lymphoma and controls were 104 children admitted with non-malignant conditions or cancers other than hematological malignancies and Kaposi sarcoma. Interviews were conducted and serological samples tested for antibodies against HIV, EBV and malaria. Odds ratios for Burkitt lymphoma were estimated using unconditional logistic regression adjusting for sex, age, and residential district. Cases had a mean age of 7.1 years and 60% were male. Cases were more likely than controls to be HIV positive (Odds ratio (OR = 12.4, 95% Confidence Interval (CI 1.3 to 116.2, p = 0.03. ORs for Burkitt lymphoma increased with increasing antibody titers against EBV (p = 0.001 and malaria (p = 0.01. Among HIV negative participants, cases were thirteen times more likely than controls to have raised levels of both EBV and malaria antibodies (OR = 13.2; 95% CI 3.8 to 46.6; p = 0.001. Reported use of mosquito nets was associated with a lower risk of Burkitt lymphoma (OR = 0.2, 95% CI, 0.03 to 0.9, p = 0.04. CONCLUSIONS: Our findings support prior evidence that EBV and malaria act jointly in the pathogenesis of Burkitt lymphoma, suggesting that malaria prevention may decrease the risk of Burkitt lymphoma. HIV may also play a role in the etiology of this childhood tumor.

  14. Molecular resemblance of an AIDS-associated lymphoma and endemic Burkitt lymphomas: Implications for their pathogenesis

    Non-Hodgkin lymphoma is a common feature of AIDS. Approximately 30-40% of these tumors exhibit clinical features suggestive of endemic Burkitt lymphoma: they are aggressive malignancies that occur in association with Epstein-Barr virus infection, they arise in the setting of immunosuppression, and they carry t(8;14) translocations without detectable rearrangement of the MYC oncogene. To understand the molecular basis of these parallels, the authors analyzed a case of Epstein-Barr-positive AIDS-associated undifferentiated lymphoma. Southern blots show that the tumor exhibits immunoglobulin joining segment rearrangement but no rearrangement of the MYC oncogene. Cloning of the rearranged joining segment allowed the isolation of recombinant clones encompassing the translocation breakpoint, and sequencing of the translocation junction disclosed that the breakpoint is situated 7 base pairs from the chromosome 14 site involved in a previously described endemic Burkitt lymphoma translocation. Furthermore, the breakpoint is situated far from MYC on chromosome 8, a constant finding in endemic Burkitt lymphomas. That the molecular architecture of the translocation in this case is strikingly similar to previously analyzed translocations from endemic Burkitt lymphomas strongly suggests that common molecular mechanisms must be operative in the pathogenesis of these tumors

    African Burkitt lymphoma is an aggressive B-cell, non-Hodgkin lymphoma linked to Plasmodium falciparum malaria. Malaria biomarkers related to onset of African Burkitt lymphoma are unknown. We correlated age-specific patterns of 2,602 cases of African Burkitt lymphoma (60% male, mean ± SD age = 7.1 ± 2.9 years) from Uganda, Ghana, and Tanzania with malaria biomarkers published from these countries. Age-specific patterns of this disease and mean multiplicity of P. falciparum malaria parasites, defined as the average number of distinct genotypes per positive blood sample based on the merozoite surface protein-2 assessed by polymerase chain reaction, were correlated and both peaked between 5 and 9 years. This pattern, which was strong and consistent across regions, contrasted parasite prevalence, which peaked at 2 years and decreased slightly, and geometric mean parasite density, which peaked between 2 and 3 years and decreased sharply. Our findings suggest that concurrent infection with multiple malaria genotypes may be related to onset of African Burkitt lymphoma.

    2009-06-01

    Full Text Available Abstract Introduction Burkitt lymphoma and B cell lymphomas in childhood may arise in many atypical locations, which on rare occasions can include gastric mucosa. A case of primary gastric Burkitt lymphoma is described in a child presenting as a protein-losing enteropathy, including the direct monitoring of the disease response by sequential endoscopic biopsy and molecular analysis. Case presentation We report a 9-year-old boy who presented with gross oedema, ascites and respiratory distress caused by a protein-losing enteropathy. Initial imaging investigations were non-diagnostic but gastroduodenal endoscopy revealed massive involvement of the gastric mucosa with a primary Burkitt lymphoma. His subsequent clinical progress and disease response were monitored directly by endoscopy and he remains in clinical remission 4 years after initial diagnosis. Conclusions This is the first case report of primary Burkitt lymphoma presenting as a protein-losing enteropathy. The clinical course and progress of the patient were monitored by sequential endoscopic biopsy, histology and molecular analysis by fluorescence in situ hybridisation.

  18. Ileocecal Burkitt's Lymphoma Presenting as Ileocolic Intussusception With Appendiceal Invagination and Acute Appendicitis

    2010-06-01

    Full Text Available Intussusception is a common cause of abdominal pain in children. Although most cases are idiopathic, about 10% of cases have a pathologic lead point. Burkitt's lymphoma is not a common etiology. Burkitt's lymphoma might present primarily as intussusception in children but has rarely been associated with appendicitis. We report a case in which a 10-year-old obese boy who initially presented with acute appendicitis due to ileocolic intussusception with appendiceal invagination. He underwent one-trocar laparoscopy and antibiotic treatment. The symptoms recurred 10 days after discharge. Colonoscopy disclosed ileocecal Burkitt's lymphoma as the pathological lead point. This case emphasizes the importance of the age of the patient and the anatomic location of the intussusception related to possible etiology, and hence the most appropriate surgical procedure.

    2004-01-01

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

    2012-01-01

    Full Text Available Paravertebral malignant tumors constitute 4.8% of cancer cases in pediatric oncology and are mostly composed of neuroblastoma (46.4% and soft tissue sarcomas (35.7%. We describe the case of a Caucasian 6-year-old boy who was admitted for middle back pain radiated to limbs and progressively increasing weakness of the legs, suggesting a spinal cord disease. The exploration revealed two paravertebral masses extending through the neural foraminae into the epidural space. The association with elevated serum neuron specific enolase suggested at first the diagnosis of neuroblastoma, but the pathological examination revealed a Burkitt's lymphoma. This is a rare location of sporadic Burkitt's lymphoma with neurologic syndrome as first symptoms.

    MYC-rearranged (MYC-R) lymphomas other than Burkitt lymphoma (BL) are very aggressive, with poor prognosis when treated with standard regimens. We aimed to study the characteristics and outcome of a series of MYC-R lymphomas comparing the treatment results between R-CHOP based and a specific intensive regimen for BL (BURKIMAB). Retrospective study of patients diagnosed with MYC-R. Translocations of MYC, BCL2 and BCL6 were evaluated by fluorescent in situ hybridization. Patients were treated with either, R-CHOP based immunochemotherapy or the Burkitt type regimen, BURKIMAB. Thirty-four MYC-R lymphoma cases were studied: 21 treated with R-CHOP and 13 treated with BURKIMAB. There were no differences in CR rate; 45% (9/20) for R-CHOP and 42% (5/12) for BURKIMAB (P=.99). Although overall survival (OS) and progression free survival (PFS) of BURKIMAB-treated patients were better than those of R-CHOP-treated (3y-OS: 46 vs. 24%; 3y-PFS: 46 vs. 10%), the differences were not statistically significant. MYC-R lymphomas show poor outcomes even when treated with intensive immunochemotherapy for BL. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    Th primary thyroid lymphoma is a rare neoplasm, above all in children. We present a case of a child with Burkitt's thyroid lymphoma as the only manifestation of this disease, associated to lymphocytic thyroiditis. Clinically, it initiated as a rapidly growing goiter with compressive symptomatology. The X-ray findings are described: hypoechoic and hypodense multiple nodes that affect the right thyroid lobe and isthmus, with extraglandular extension to the vascular space and to the mediastinum. The differential diagnosis is considered with other more frequent thyroid pathologies in this age group. (Author) 14 refs

    Purpose: To evaluate the natural history of children with abdominal Burkitt's lymphoma who had complete clinical remission and residual abdominal mass after treatment. Material and methods: The charts and imaging findings of all children with abdominal Burkitt's lymphoma treated and followed at our medical center between 1988 and 1999 were reviewed for the presence, management, clinical course, and prognosis of residual mass. Results: Only children who achieved complete clinical remission were included. The study group consisted of 33 children (20 boys and 13 girls) aged 2.6-17.6 years (mean 7.2 years). Of these, seven (20.6 %) were found to have a residual abdominal mass. Two underwent second-look operation with no evidence of viable tumor on histology. The remaining five were followed by imaging studies for 2.2-9.1 years (mean 6.1 years); none relapsed. Conclusion: Residual mass is not uncommon in children with abdominal Burkitt's lymphoma. The presence of residual mass in a child with complete clinical remission does not alter the long-term prognosis. Therefore, in children with Burkitt's lymphoma and residual mass with no other signs of disease activity, expectant watching may be appropriate. (orig.)

    1986-01-01

    The radiological studies of 18 children with biopsy proved Burkitt's lymphoma were analyzed retrospectively. Before therapy the genitourinary tract was evaluated in 15 children by excretory urography, sonography, computerized tomography and/or gallium citrate scintigraphy. Genitourinary abnormalities were detected in 9 children. Changes due to tumor included renal or ureteral displacement in 4 children, hydronephrosis in 3 and intraparenchymal masses in 4. Extrinsic compression of the bladder causing no compromise of function was seen in only 2 children. Gonadal involvement occurred in 2 boys and 1 girl. The modality of choice for evaluating the genitourinary tract in patients with Burkitt's lymphoma has been excretory urography. Since ultrasound and computerized tomography provide more direct information about tumor deposits within the kidney and retroperitoneum, either should be performed in this population before initiation of chemotherapy

    Burkitt lymphoma is one of the most common types of haematopoietic malignancy in children and adolescents. Mda-7/IL-24 had been identified as a differentiation inducer of Burkitt lymphoma cells. Previous studies have revealed that knockdown of C-myb can also lead to the terminal differentiation of Burkitt lymphoma cells. The aim of the present study was to investigate the correlation between the expression of Mda-7/IL-24 and C-myb, as well as their prognostic significance, for Burkitt lymphoma patients. The tumour tissues were collected from 59 cases of Burkitt lymphoma patients and detected with Western blotting and immunohistochemistry. The results showed that the expression of Mda-7/IL-24 was lower, whereas the expression of C-myb was higher in Burkitt lymphoma tissues compared to specimens of normal lymph node tissues. Furthermore, C-myb expression was negatively correlated with Mda-7/IL-24 expression at the protein level in Burkitt lymphoma tissues and cell lines. Both the expression of Mda-7/IL-24 and C-myb in Burkitt lymphoma tissues was associated with some clinicopathological parameters, such as clinical stage, infiltration in the bone marrow, Ki67 and overall survival rates. These results indicated that low expression of Mda-7/IL-24 along with high expression of C-myb are predictors for poor prognosis of Burkitt lymphoma patients; this outcome suggests that Mda-7/IL-24 and C-myb might be potential targets for clinical treatment of Burkitt lymphoma.

    Recent advancements in the field of cancer diagnosis and chemotherapy have led to higher rates of survival for children with malignant tumors. More than 75% of pediatric patients diagnosed with malignancies survive more than 5 years. These advancements have resulted in additional responsibilities for dental professionals to diagnose, evaluate, prevent, stabilize, and manage the oral and dental problems that can compromise the quality of life of these children. This case report highlights the importance of professional and self-administered oral prophylactic measures and patient compliance in the successful oral rehabilitation of a pediatric patient with Burkitt lymphoma. © 2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

    A 35-year-old woman without any known systemic disorder presented with a complaint of painful and rapidly increasing proptosis in her right eye. Based on the clinical, radiological, analytical and ophthalmological assessments, the diagnosis made was Burkitt's lymphoma in acquired immunodeficiency syndrome.

    Th primary thyroid lymphoma is a rare neoplasm, above all in children. We present a case of a child with Burkitt's thyroid lymphoma as the only manifestation of this disease, associated to lymphocytic thyroiditis. Clinically, it initiated as a rapidly growing goiter with compressive symptomatology. The X-ray findings are described: hypoechoic and hypodense multiple nodes that affect the right thyroid lobe and isthmus, with extraglandular extension to the vascular space and to the mediastinum. The differential diagnosis is considered with other more frequent thyroid pathologies in this age group. (Author) 14 refs.

    Full Text Available Discordant lymphoma is rare condition in which different types of malignant lymphomas occurring in different anatomic sites. The two diseases may present clinically as concurrent or sequential disease (10. Herein we are reporting a Pakistani female in her 60s, a carrier of hepatitis B virus with multiple comorbidities presented with cervical lymphadenopathy, diagnosed as Hodgkin's lymphoma, mixed cellularity. During the staging workup, the patient was discovered to have extensive bone marrow (BM involvement by Burkitt leukaemia/lymphoma (BL. Cytogenetic analysis revealed positivity for t(8;14(q24;q32 confirmed by Fluorescence In Situ Hybridization (FISH for IGH/MYC. Epstein-Barr virus (EBV was demonstrated heavily in our case, with (EBV DNA of 24,295,560 copies/ml by PCR at time of presentation, in addition, the neoplastic cells in both diagnostic tissues (cervical lymph node and BM demonstrated positivity for EBV. A diagnosis of concomitant EBV related discordant lymphoma (classical Hodgkin lymphoma (cHL and Burkitt lymphoma (BL in leukemic phase was made. Among all reported cases, this case is highly exceptional because it is the first case of discordant/composite lymphoma, with this combination and concomitant presentation. Since we are dealing with a case with an exceptionally rare combination, we found it significant to elaborate more on its clinical features, contributing factors including EBV role, response to treatment, complications, and prognosis.

    Full Text Available Endemic Burkitt lymphoma (eBL is primarily found in children in equatorial regions and represents the first historical example of a virus-associated human malignancy. Although Epstein-Barr virus (EBV infection and MYC translocations are hallmarks of the disease, it is unclear whether other factors may contribute to its development. We performed RNA-Seq on 20 eBL cases from Uganda and showed that the mutational and viral landscape of eBL is more complex than previously reported. First, we found the presence of other herpesviridae family members in 8 cases (40%, in particular human herpesvirus 5 and human herpesvirus 8 and confirmed their presence by immunohistochemistry in the adjacent non-neoplastic tissue. Second, we identified a distinct latency program in EBV involving lytic genes in association with TCF3 activity. Third, by comparing the eBL mutational landscape with published data on sporadic Burkitt lymphoma (sBL, we detected lower frequencies of mutations in MYC, ID3, TCF3 and TP53, and a higher frequency of mutation in ARID1A in eBL samples. Recurrent mutations in two genes not previously associated with eBL were identified in 20% of tumors: RHOA and cyclin F (CCNF. We also observed that polyviral samples showed lower numbers of somatic mutations in common altered genes in comparison to sBL specimens, suggesting dual mechanisms of transformation, mutation versus virus driven in sBL and eBL respectively.

    Constitutional mismatch repair deficiency (CMMRD) is a cancer predisposition syndrome associated with a high risk of developing early-onset malignancies of the blood, brain, and intestinal tract. We present the case of a patient with T-lymphoblastic lymphoma at the age of 3 years, followed by Burkitt lymphoma 10 years later. This patient also exhibited numerous nonmalignant findings including café au lait spots, lipomas, bilateral renal nodules, a nonossifying fibroma, multiple colonic adenomas, and a rapidly enlarging pilomatrixoma. The spectrum of malignant and nonmalignant neoplasms in this patient highlights the remarkable diversity, and early onset, of lesions seen in children with CMMRD. © 2016 Wiley Periodicals, Inc.

Most non-Hodgkin's lymphoma cases that are associated with acquired immunodeficiency syndrome involve extranodal sites, especially the digestive tract and the central nervous system. We report a case of primary lymphoma of the duodenum in a patient with AIDS. Upper gastrointestinal endoscopy revealed pseudopolypoid masses found in the second portion of the duodenum. A complete diagnostic study including histological, immunohistochemical and virological analyses showed high-grade B-cell Burkitt's lymphoma. The Epstein-Barr virus genome was detected in biopsies by immunohistochemical and in situ hybridization.O linfoma não-Hodgkin de células B é a segunda neoplasia mais comum em pacientes com infecção pelo vírus da imunodeficiência humana depois do sarcoma de Kaposi.

    Objective: To explore the value of 18 F fluorodeoxy-glucose (FDG) positron emission tomography (PET) in Burkitt's lymphoma. Methods: All Burkitt's lymphoma patients referred for FDG PET or FDG PET/computed tomography (CT) exams at our institution from June 2003 to June 2006 were included. Selected patients were followed and clinical information was reviewed retrospectively. Results from FDG PET-PET/CT, as blindly reviewed by a consensus of two experienced readers, were compared with the status of the disease as determined by other laboratory, clinical and imaging exams and clinical follow-up. FDG PET-PET/CT results were classified as true positive or negative and false positive or negative. The degree of FDG uptake in the positive lesions was semiquantified as maximum standard uptake value (SUVmax). Results: Fifty-seven FDG PET-PET/CT exams were done in 15 patients. Seven exams were done for initial staging, 8 during and 14 after the completion of therapy, and 28 for disease surveillance. For nodal disease FDG PET-PET/CT was true positive in 8, true negative in 47 and false positive in 2 exams (sensitivity 100%, specificity 96%). For extranodal disease FDG PET-PET/CT was true positive in 6, true negative in 48 and false positive in 3 exams (sensitivity 100%, specificity 94%). The mean SUVmax for the positive nodal lesions was 15.7 (range 6.9-21.7, median 18.5) and for extranodal lesions was 14.2 (range 6.2-24.3, median 12.4). Conclusions: FDG PET-PET/CT is sensitive for the detection of viable disease in Burkitt's lymphoma. Affected areas demonstrated high degree of uptake that was reversible upon successful implementation of treatment.

    Burkitt's lymphoma (BL) is an exceptional cause of acute renal failure (ARF). The origin of the tumor clone may be lymphoid follicles secondary to renal Epstein-Barr virus (EBV) infection. With the presentation of this clinical case, the pathogenesis, diagnostic criteria and evolution of this extremely rare affection will be discussed. A 4-year-old patient with a recent history of acute osteomyelitis of the right thigh presented an ARF without indications of post-infectious glomerulonephritis. Ultrasound showed enlarged kidneys without dilation of the excretory cavities. Diffuse interstitial infiltration of atypical lymphoid cells of medium size were noted upon renal biopsy. The tumor cells expressed antibodies against CD20, CD10, Bcl6, and Ki67 but not against Bcl2 or CD3. The search for an EBV infection was positive. A few days after diagnosis, the evolution was spontaneously fatal. BL of the kidney is a rare condition that accounts for less than 1 % of kidney tumors, associated almost invariably with EBV infection. The diagnosis is confirmed histologically by renal biopsy and the criteria of Malbrain affirms the primitive character of the lymphoma. BL of the kidney is a diagnostic and therapeutic emergency and may be fatal. Copyright © 2018 Société francophone de néphrologie, dialyse et transplantation. Published by Elsevier Masson SAS.

    The adult high-grade B-cell lymphomas sharing molecular features with Burkitt lymphoma (BL) are highly aggressive lymphomas with poor clinical outcome. High-resolution structural and functional genomic analysis of adult Burkitt lymphoma (BL) and high-grade B-cell lymphoma with BL gene signature (adult-molecularly defined BL [mBL]) revealed the MYC-ARF-p53 axis as the primary deregulated pathway. Adult-mBL had either unique or more frequent genomic aberrations (del13q14, del17p, gain8q24, and gain18q21) compared with pediatric-mBL, but shared commonly mutated genes. Mutations in genes promoting the tonic B-cell receptor (BCR)→PI3K pathway ( TCF3 and ID3 ) did not differ by age, whereas effectors of chronic BCR→NF-κB signaling were associated with adult-mBL. A subset of adult-mBL had BCL2 translocation and mutation and elevated BCL2 mRNA and protein expression, but had a mutation profile similar to mBL. These double-hit lymphomas may have arisen from a tumor precursor that acquired both BCL2 and MYC translocations and/or KMT2D ( MLL2 ) mutation. Gain/amplification of MIR17HG and its paralogue loci was observed in 50% of adult-mBL. In vitro studies suggested miR-17∼92 's role in constitutive activation of BCR signaling and sensitivity to ibrutinib. Overall integrative analysis identified an interrelated gene network affected by copy number and mutation, leading to disruption of the p53 pathway and the BCR→PI3K or NF-κB activation, which can be further exploited in vivo by small-molecule inhibitors for effective therapy in adult-mBL.

    Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases-14%) and diffuse large B......-cell lymphoma (18 cases-9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases-13%), extranodal natural killer/T-cell, nasal-type lymphoma (12 cases-6%), and primary cutaneous anaplastic large-cell lymphoma (12 cases-6%). This distribution differs from the distribution of ocular adnexal lymphoma...... and that of cutaneous lymphoma. The majority of subtypes occur in elderly patients, except for lymphoblastic lymphoma of B-cell and T-cell origin and Burkitt lymphoma, which occur in children and adolescents. Several subtypes have a male predominance, including peripheral T-cell lymphoma and Burkitt lymphoma. Only...

    1984-01-01

    Over a 15-year period, 485 cases of Burkitt's lymphoma (BL) mainly from the southern half of Ghana, were referred to the Burkitt's Tumour Project in Accra, Ghana. From an analysis of the numbers of cases referred each year, the sites of tumour involvement, and the age and sex frequencies, it was concluded that: (i) the number of cases of BL diagnosed in Ghana has decreased progressively over the last 15 years; the number of newly diagnosed cases is now only about one half of what it was 10 years ago; (ii) the male/female ratio has remained practically unchanged over this period; (iii) there has been an overall increase in patients presenting with abdominal disease and a decrease in those presenting with facial disease. This change was particularly apparent in males, in whom the proportion of cases with abdominal disease has more than doubled; (iv) there has been a progressive increase in age at presentation for both males and females over the 15-year period. The possible implications of, and reasons for the above findings are discussed.

    Data on the burden and incidence of endemic Burkitt lymphoma (eBL) across Mozambique are scarce. We retrospectively retrieved information on eBL cases from reports of the three main hospitals of Mozambique: Maputo Central Hospital (MCH), Beira Central Hospital (BCH), and Nampula Central Hospital (NCH) between 2004 and 2014. For 2015, we prospectively collected information of new eBL cases attending these hospitals. A total of 512 eBL cases were reported between 2004 and 2015: 153 eBL cases were reported in MCH, 195 in BCH, and 164 in NCH. Mean age of cases was 6.9 years (standard deviation = 2.8); 63% (319/504) of cases were males. For 2015, the estimated incidence rate of eBL was 2.0, 1.7, and 3.9 per 106 person-year at risk in MCH, BCH, and NCH, respectively. Incidence was higher in NCH (northern Mozambique), where intensity of malaria transmission is higher. Data presented show that eBL is a common pediatric malignancy in Mozambique, as observed in neighboring countries. PMID:27799648

    Full Text Available El linfoma de Burkitt no endémico es un tumor de frecuente localización abdominal, por lo que se debe tener presente ante cualquier masa intraabdominal. Aunque el tratamiento de elección es la quimioterapia, existe controversia respecto del papel que debe desempeñar la cirugía, especialmente en casos donde el diagnóstico se establece durante una laparotomía exploradora. Este fue el caso de una adolescente de 14 años que presentó una masa hipogástrica y otra menor en la fosa ilíaca derecha. Algunos autores no aceptan la cirugía y añaden que puede retrasar y complicar el tratamiento quimioterápeutico, mientras que otros autores defienden la cirugía reductora de masa tumoral asociada a la quimioterapia. Esta controversia es especialmente importante cuando el diagnóstico se establece en el curso de una laparotomía exploradora, durante la cual hay que decidir si extirpar la masa tumoral o no hacerlo. En nuestro caso decidimos extirpar todo el tumor macroscópico. La buena evolución de nuestra paciente y los resultados comunicados apoyan esta postura.Non-endemic Burkitt's lymphoma is a tumor of frequent abdominal localization that should be taken into consideration before any intraabdominal mass. Although chemotherapy is the election treatment, there is controversy as regards the role surgery should play, specially in those cases where the diagnosis is established by explorative laparotomy. This was the case of a 14-year-old adolescent that presented a hypogastric mass and another lower mass in the right iliac fossa. Some authors do not accept surgery and state that it may delay and complicate chemotherapy, whereas other authors defend the tumoral mass-reducing surgery associated with chemotherapy. This controversy is particularly important when the diagnosis is made in the course of an explorative laparotomy and it should be decided wether to remove the tumoral mass or not. In our case, it was decided to remove the whole macroscopic

    Burkitt's lymphoma (BL) accounts for the majority of childhood malignancies seen in sub-Saharan Africa. In Malawi, cyclophosphamide (CPM), the mainstay of treatment for endemic BL, is effective in around 50% of cases. Evidence exists in support of an association between activation of replication of Epstein-Barr virus (EBV) in the tumour and response to this chemotheraupeutic agent. Phenylbutyrate (PB), approved for treatment of inborn errors of the urea cycle with minimal toxicity in children, induces EBV replication and cell lysis in BL-derived cell cultures. It has also shown some success as adjuvant in treatment of chronic leukaemia and lymphoma. We tested in African BL patients with CPM-resistant tumours, and thus unlikely to survive, the hypothesis that PB can reverse this resistance. A study of five patients showed PB before CPM to induce shrinkage of CPM-resistant tumours in two of them. Findings suggested that for this effect PB pre-treatment should be given for a week before CPM treatment. A larger study is indicated.

    Forty cases of ovarian lymphoma and two of extramedullary leukemia were examined with emphasis on histologic types correlated with age, modes of presentation, operative findings, including frequency of bilaterality and omental spread, clinical course following therapy, and problems in differential diagnosis. Although most cases were referred with diagnoses other than lymphoma (granulosa cell tumor or dysgerminoma, occasionally anaplastic tumor, Krukenberg tumor, or metastatic breast carcinoma), utilization of sections cut at 4 mu and stained with hematoxylin and eosin, or sections stained by the methyl green pyronine (MGP), naphthol-ASD esterase (NASD) or periodic acid-Schiff (PAS) methods helped bring out the lymphoid or hematopoietic nature of the cells. Sixteen patients were under 20 years of age. They had small noncleaved cell lymphoma (undifferentiated Burkitt's and non-Burkitt's, 10 cases), diffuse immunoblastic large cell lymphoma (4 cases), or acute granulocytic leukemia (2 cases). Twenty-six patients were 29 to 74 years of age and had diffuse large cell lymphoma (10 cases), diffuse immunoblastic large cell lymphoma (9 cases), follicular (nodular) lymphoma (6 cases) or small noncleaved cell lymphoma (1 case). Pain with an abdominal or pelvic mass was the most common presentation. Nine tumors were discovered during investigation of other gynecologic complaints. At laparotomy, the tumors in 55% of cases involved both ovaries, and in 64% also involved extragonadal sites (usually omentum, fallopian tubes, or lymph nodes). Seventeen patients had tumor affecting one ovary, seven of these without any evidence of extragonadal spread. Forty-two percent (15) of 37 patients with follow-up were alive after 2 years. Only nine patients survived more than 5 years; two subsequently died of lymphoma. Favorable prognostic features included: (1) FIGO stage IA; (2) unilateral ovarian involvement; (3) focal involvement of one ovary; and (4) follicular (nodular) lymphoma.

    Here, we report the first molecular cytogenetic characterization of the BALB/cAnN mouse derived B-cell non-Hodgkin lymphoma (B-cell NHL) cell lines A-20. Even though previously used as a model for testing of, for example, dexametason, up to present, no data in the genetic properties of A-20 were available. The present study closed this gap and provides evidence that A-20 is a model for B-cell NHL subgroup sporadic Burkitt's lymphoma. C-myc oncogene is involved in a translocation and copy number alterations as gain of murine 14q material could be observed. Interestingly, the cell line showed the karyotype 39,X,-X or -Y,t(2;15)(qE5;qD2),del(6)(qB3qC3),del(9)(qA3qA4),dup(14)(qE1qE4) in ~95% of the cells, being exceptionally stable for cell lines being established 38 years ago. Still, ~5% of the cells showed polyploidization followed by chromothripsis. It remains to be determined if this can be observed also in other cell lines, just has not been reported yet, and/or if it is a unique feature of A-20. Overall, finally here, the necessary genetic data to identify A-20 as a model for human sporadic Burkitt's lymphoma are provided.

    Relapsed or refractory Burkitt's lymphoma often has a poor prognosis in spite of intensive chemotherapy that induces apoptotic and/or necrotic death of lymphoma cells. Rapamycin (Rap) brings about autophagy, and could be another treatment. Further, anti-CD19-targeted liposomal delivery may enable Rap to kill lymphoma cells specifically. Rap was encapsulated by anionic liposome and conjugated with anti-CD19 antibody (CD19-GL-Rap) or anti-CD2 antibody (CD2-GL-Rap) as a control. A fluorescent probe Cy5.5 was also liposomized in the same way (CD19 or CD2-GL-Cy5.5) to examine the efficacy of anti-CD19-targeted liposomal delivery into CD19-positive Burkitt's lymphoma cell line, SKW6.4. CD19-GL-Cy5.5 was more effectively uptaken into SKW6.4 cells than CD2-GL-Cy5.5 in vitro. When the cells were inoculated subcutaneously into nonobese diabetic/severe combined immunodeficiency mice, intravenously administered CD19-GL-Cy5.5 made the subcutaneous tumor fluorescent, while CD2-GL-Cy5.5 did not. Further, CD19-GL-Rap had a greater cytocidal effect on not only SKW6.4 cells but also Burkitt's lymphoma cells derived from patients than CD2-GL-Rap in vitro. The specific toxicity of CD19-GL-Rap was cancelled by neutralizing anti-CD19 antibody. The survival period of mice treated with intravenous CD19-GL-Rap was significantly longer than that of mice treated with CD2-GL-Rap after intraperitoneal inoculation of SKW6.4 cells. Anti-CD19-targeted liposomal Rap could be a promising lymphoma cell-specific treatment inducing autophagic cell death

    A geographical and causal connection has long been recognized between malaria, Epstein-Barr virus (EBV) infection and Burkitt's lymphoma (BL), but the underlying mechanisms remain obscure. Potential clues are that the malaria parasite Plasmodium falciparum selectively absorbs vitamin A from the host and depends on it for its biological activities; secondly, alterations in vitamin A (retinoid) metabolism have been implicated in many forms of cancer, including BL. The first author has proposed that the merozoite-stage malaria parasite, emerging from the liver, uses its absorbed vitamin A as a cell membrane destabilizer to invade the red blood cells, causing anemia and other signs and symptoms of the disease as manifestations of an endogenous form of hypervitaminosis A (Mawson AR, Path Global Health 2013;107(3):122-9). Repeated episodes of malaria would therefore be expected to expose the tissues of affected individuals to potentially toxic doses of vitamin A. It is proposed that such episodes activate latent EBV infection, which in turn activates retinoid-responsive genes. Expression of these genes enhances viral replication and induces germinal center (GC) B cell expansion, activation-induced cytidine deaminase (AID) expression, and c-myc translocation, which in turn predisposes to BL. Thus, an endogenous form of retinoid toxicity related to malaria infection may be the common factor linking frequent malaria, EBV infection and BL, whereby prolonged exposure of lymphatic tissues to high concentrations of retinoids may combine to induce B-cell translocation and increase the risk of Burkitt's lymphoma. © 2017 UICC.

    Full Text Available Additional chromosomal abnormalities are currently detected in Burkitt's lymphoma. They play major roles in the progression of BL and in prognosis. The genes involved remain elusive. A whole-genome oligonucleotide array CGH analysis correlated with karyotype and FISH was performed in a set of 27 Burkitt's lymphoma-derived cell lines and primary tumors. More than half of the 145 CNAs2 Mb, gains were found in 1q (12/27, 13q (7/27, 7q (6/27, 8q(4/27, 2p (3/27, 11q (2/27 and 15q (2/27.

Twenty one minimal critical regions (MCR, (range 0.04-71.36 Mb, were delineated in tumors and cell lines. Three MCRs were localized to 1q. The proximal one was mapped to 1q21.1q25.2 with a 6.3 Mb amplicon (1q21.1q21.3 harboring BCA2 and PIAS3. In the other 2 MCRs, 1q32.1 and 1q44, MDM4 and AKT3 appeared as possible drivers of these gains respectively. The 13q31.3q32.1 MCR contained an amplicon and ABCC4 might be the driver of this amplicon. The 40 Kb 2p16.1 MCR was the smallest gained MCR and specifically encompassed the REL oncogene which is already implicated in B cell lymphomas. The most frequently deleted MCR was 3p14.1 that removed the fifth exon of FHIT. Further investigations which combined gene expression and functional studies are essential to understand the lymphomagenesis mechanism and for the development of more effective, targeted therapeutic strategies.

    Full Text Available Abstract Background Resveratrol (RES, a natural phytoalexin found at high levels in grapes and red wine, has been shown to induce anti-proliferation and apoptosis of human cancer cell lines. However, the underlying molecular mechanisms are at present only partially understood. Method The effects of RES on activation of unfolded protein responses (UPR were evaluated using Western blotting, semi-quantitative and real-time RT-PCR. Cell death was evaluated using Annexin V/PI staining and subsequent FACS. Results Similar as tunicamycin, treatment with RES lead to the activation of all 3 branches of the UPR, with early splicing of XBP-1 indicative of IRE1 activation, phosphorylation of eIF2α consistent with ER resident kinase (PERK activation, activating transcription factor 6 (ATF6 splicing, and increase in expression levels of the downstream molecules GRP78/BiP, GRP94 and CHOP/GADD153 in human Burkitt's lymphoma Raji and Daudi cell lines. RES was shown to induce cell death, which could be attenuated by thwarting upregulation of CHOP. Conclusions Our data suggest that activation of the apoptotic arm of the UPR and its downstream effector CHOP/GADD153 is involved, at least in part, in RES-induced apoptosis in Burkitt's lymphoma cells.

    The abdomen, in particular the ileocecal region, appendix and colon, is the most common primary site for Burkitt non Hodgkin's lymphoma (NHL). Involvement of the bile duct is rare. The authors describe a patient with abdominal NHL in which jaundice due to bile duct obstruction was the first clinical sign. Case report: a 3 year old white boy presented with one month of progressive jaundice, clay-colored stools, tea colored urine and increase of abdominal volume. Physical examination showed jaundice 3+/4+ and pale mucosa. The abdomen was moderately distended and timpanous and the liver was enlarged. Laboratory examinations confirmed cholestasis with total bilirubin of 8.2 mg/dl (direct bilirubin of 7.8 mg/dl), and microcytic and hypochromic anemia. Ultrasonography (US) and abdominal CT showed two solid tumors in hepatic hilar topography, and dilated intrahepatic biliary tree. The Doppler US showed hepatic artery and portal vein dislocation by the nodules. Comment: although jaundice occurs frequently as a late manifestation of NHL, it is rarely seen as the presenting sign. When jaundice is the first clinical sign and image studies show hepatic hilar tumor and bile duct obstruction, NHL should be considered in the differential diagnosis. (author)

Giovanni e Paolo, Venice, Italy Abstract: About one-half of all Burkitt lymphoma (BL patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA subset, defined by an age between 15 and 25–40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein–Barr virus, while the epidemic form strictly follows the pattern of infection by HIV. BL shows propensity to extranodal involvement of abdominal organs, bone marrow, and central nervous system, and can cause severe metabolic and renal impairment. Nevertheless, BL is highly responsive to specifically designed short-intensive, rotational multiagent chemotherapy programs, empowered by the anti-CD20 monoclonal antibody rituximab. When carefully applied with appropriate supportive measures, these modern programs achieve a cure rate of approximately 90% in the average AYA patient, irrespective of clinical stage, which is the best result achievable in any aggressive lymphoid malignancy to date. The challenges ahead concern the following: optimization of management in underdeveloped countries, with reduction of diagnostic and referral-for-care intervals, and the applicability of currently curative regimens; the development of lower intensity but equally effective treatments for frail or

  5. c-Myc over-expression in Ramos Burkitt's lymphoma cell line predisposes to iron homeostasis disruption in vitro

    2006-01-01

    Burkitt's lymphoma is an aggressive B-cell neoplasm resulting from deregulated c-myc expression. We have previously shown that proliferation of Burkitt's lymphoma cell lines such as Ramos is markedly reduced by iron treatment. It has been shown that iron induces expression of c-myc which, owing to its transcriptional regulatory functions, regulates genes involved in iron metabolism. Transient enhancement of c-myc expression by iron could increase the expression of genes involved in iron incorporation, which could lead to an accumulation of intracellular free iron. Here, we have investigated whether cells with a high basal level of c-Myc were more likely to accumulate free iron. Our results suggest that the basal level of c-Myc in Ramos cells is twofold higher than what is seen in HL-60 cells. Moreover, in Ramos cells, where c-Myc is expressed at a high level, H-ferritin expression is down-regulated, transferrin receptor (CD71) expression is increased, and ferritin translation is inhibited. These modifications in iron metabolism, resulting from the strong basal expression of c-Myc, and amplified by iron addition, could lead to a disruption in homeostasis and consequently to growth arrest

    Fast and reliable differential diagnosis of Burkitt lymphoma (BL) vs. diffuse large B cell lymphoma (DLBCL) is of major importance for therapeutic decisions and patient outcome. Aggressive B cell non-Hodgkin lymphomas (B-NHLs) that do not belong to the abovementioned entities were categorized by the current WHO lymphoma classification as "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and BL" (DLBCL/BL). We have recently described a DLBCL/BL subgroup with recurrent chromosome 11q aberrations, resembling BL (B-NHLs[11q]). Here, we analyzed 102 prospectively collected fine needle aspirates from patients with aggressive B-NHLs in order to investigate the potential of microRNA (miR)-155, its precursor BIC, as well as miR-21 and miR-26a to differentiate BL from DLBCL, and from DLBCL/BL that include B-NHLs[11q]. Both BL and DLBCL/BL cases, including B-NHLs[11q], demonstrated significantly lower expression levels of miR-155/BIC, miR-21, and miR-26a compared to primary DLBCL. In conclusion, the miRs expression in B-NHLs[11q] provides a new suggestion, in addition to pathomorphological and clinical similarities between classical, i.e., MYC translocation-positive BL, and B-NHLs[11q], to recognize the B-NHLs[11q] subgroup of DLBCL/BL category as a MYC translocation-negative variant of BL in most cases, and points to the potential utility of miR-155/BIC/miR-21/miR-26a for the differential diagnosis of a heterogeneous category of DLBCL/BL.

    Burkitt lymphoma (BL) is a rare, highly aggressive B-cell malignancy treated most successfully with brief-duration, high-intensity chemotherapeutic regimens. The benefit of the addition of rituximab to these regimens remains uncertain. We sought to examine the effectiveness of chemotherapy with and without rituximab in patients with BL. This study is a retrospective cohort study of all adult patients with BL diagnosed and treated with modern, dose-intense chemotherapeutic regimens from 1998-2008 at two tertiary care institutions. All cases were confirmed by application of WHO 2008 criteria by hematopathologists. Medical records were reviewed for patient-, disease-, and treatment- related factors as well as treatment response and survival. Factors associated with survival were analyzed using Cox proportional hazards modeling. A total of 35 patients were analyzed: 18 patients received rituximab with chemotherapy (R-chemo) and 17 received chemotherapy (chemo) alone. The median age was 42 (range 20-74 years); 57% were male; 71% had Ann Arbor Stage IV disease; 33% had central nervous system involvement; 78% had an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. R-chemo was associated with significantly longer overall survival (OS) than chemo alone (5-year OS 70% and 29%, respectively, p = 0.040). On multivariate regression analysis, poor performance status and central nervous system involvement were associated with poorer survival. The addition of rituximab to chemotherapy was associated with improved OS in patients with Burkitt lymphoma. Poor performance status and central nervous system involvement were prognostically significant on multivariate analysis.

    This study was purposed to investigate the effects of phenylhexyl isothiocyanate (PHI) on Burkitt lymphoma Daudi cell line and regulation of histone acetylation and methylation in Daudi cells, and to explore the potential mechanism. The apoptotic rate of Daudi cells treated with PHI was measured by flow cytometry, the changes of histone H3 and H4 acetylation, histone H3K9 and H3K4 methylation in Daudi cells treated with PHI were detected by Western blot. The results showed that PHI could induce apoptosis of Daudi cells, increased the acetylation level of H3 and H4, enhanced the methylation of H3K4, but reduced the methylation of H3K9. It is concluded that the PHI can up-regulate the acetylation level of histone H3 associated with transcription stimulation and the methylation of histone H3K4, down-regulate the methylation on histone H3K9 associated with transcription inhibition, promotes the apoptosis of Daudi cells. PHI may be a potential agent for target therapy of lymphoma.

    Adult Burkitt lymphoma (BL) is an aggressive disease characterized by frequent extranodal presentation, bulky disease and a rapid clinical course. Although intensive chemotherapeutic regimes result in long-term disease-free survival in most patients, a significant proportion of patients will have high-risk disease that may be refractory or that will relapse. In these patients, the role of hematopoietic SCT is not well defined, especially in the era of modern chemoimmunotherapy. Upfront auto-SCT has been reported to be feasible in patients who have high-risk features at presentation, and in whom it is a clinical option. In patients with relapsed disease, auto-SCT can result in a PFS of 30-40%. Allo-SCT is an option in relapsing patients with a sibling or matched related donor who may not be eligible for, or may have previously received, an auto-SCT; the role of RIC and T-cell depletion is not well defined. Disease status at transplant is the most significant predictor of outcome in patients undergoing SCT. Here we review the available evidence pertaining to SCT in patients with BL, including in those who are HIV positive (HIV+) and those with B-cell lymphoma unclassified (BCLU). Prospective studies in the era of modern intensive chemoimmunotherapeutic regimes are required to delineate the precise role of transplantation for BL. Developments in molecular diagnostics, incorporation of FDG-PET and minimal residual disease monitoring along with new therapies may further assist in refining treatment algorithms.

Records of all patients diagnosed with BL at three Cameroon Baptist Convention hospitals were reviewed to ascertain the recorded HIV status and outcome of treatment. Of 979 patients diagnosed with BL, 717 were tested for HIV and 11 (1.5% were HIV-positive. Three of eight patients treated with both cyclophosphamide (CPM-based chemotherapy and antiretrovirals were alive at 62, 96 and 111 months, respectively. The HIV rate was comparable to that of 1% for the general population of children aged <15 years. Low-cost high-frequency CPM was the only available treatment option for BL and was associated with 37.5% long-term survival in a resource-limited setting.

    Burkitt lymphoma (BL) occurs at all ages, but the patterns of Epstein-Barr virus (EBV) positivity in relation to human immunodeficiency virus (HIV), immunoprofiles and age have not been fully explored. BL tissues from residual tissue repositories, and two academic centers in the United States were examined by expert hematopathologists for morphology, immunohistochemistry, MYC rearrangement, EBV-encoded RNA (EBER), and diagnosed according to the 2008 WHO lymphoma classification. Analysis was done using frequency tables, Chi-squared statistics, and Student's t-test. Of 117 cases examined, 91 were confirmed as BL. The age distribution was 26%, 15%, 19%, and 29% for 0-19, 20-34, 35-59, 60+ years, and missing in 11%. MYC rearrangement was found in 89% and EBER positivity in 29% of 82 cases with results. EBER positivity varied with age (from 13% in age group 0-19 to 55% in age group 20-34, and fell to 25% in age group 60+ years, p = 0.08); with race (56% in Blacks/Hispanics vs 21% in Whites/Asians/Pacific Islanders, p = 0.006); and by HIV status (64% in HIV positive vs 22% in HIV negative cases, p = 0.03). EBER positivity was demonstrated in about one-third of tumors and it was strongly associated with race and HIV status, and marginally with age-group. © 2013 APMIS Published by Blackwell Publishing Ltd.

    Full Text Available Assessing molecular persistent or minimal residual disease (PD/MRD in childhood Burkitt lymphoma (BL is challenging because access to original tumor is usually needed to design patient-specific primers (PSPs. Because BL is characterized by rearranged immunoglobulin heavy chain (IgVH genes, IgVH primer pools from IgVH1–IgVH7 regions were tested to detect PD/MRD, thus eliminating the need for original tumor. The focus of the current study was to assess the feasibility of using IgVH primer pools to detect disease in clinical specimens. Fourteen children diagnosed with B-NHL had follow-up repository specimens available to assess PD/MRD. Of the 14 patients, 12 were PD/MRD negative after 2 months of therapy and remained in remission at the end of therapy; 2/14 patients were PD/MRD positive at 2-3 months and later relapsed. PSP-based assays from these 14 patients showed 100% concordance with the current assay. This feasibility study warrants further investigation to assess PD/MRD using IgVH primer pools, which could have clinical significance as a real-time assessment tool to monitor pediatric BL and possibly other B-cell non-Hodgkin lymphoma therapy.

    Assessing molecular persistent or minimal residual disease (PD/MRD) in childhood Burkitt lymphoma (BL) is challenging because access to original tumor is usually needed to design patient-specific primers (PSPs). Because BL is characterized by rearranged immunoglobulin heavy chain (IgV(H)) genes, IgV(H) primer pools from IgV(H1)-IgV(H7) regions were tested to detect PD/MRD, thus eliminating the need for original tumor.

    Since its first description by Denis Burkitt, endemic Burkitt's lymphoma (BL), the most common childhood cancer in sub-Saharan Africa, has led scientists to search for clues to the origins of this malignancy. The discovery of Epstein-Barr virus (EBV) in BL cells over 50 years ago led to extensive sero-epidemiology studies and revealed that rather than being a virus restricted to areas where BL is endemic, EBV is ubiquitous in the world's population with an estimated greater than 90% of adults worldwide infected. A second pathogen, Plasmodium falciparum (P. falciparum) malaria is also linked to BL. In this review, we will discuss recent studies that indicate a role for P. falciparum malaria in dysregulating EBV infection, and increasing the risk for BL in children living where P. falciparum malaria transmission is high.

    The interplay between Epstein-Barr virus infection, malaria, and endemic Burkitt's Lymphoma is not well understood. Reports show diminished EBV-specific Th1 responses in children living in malaria endemic areas and deficiency of EBNA1-specific IFN-γ T cell responses in children with endemic Burkitt's Lymphoma (eBL). This study, therefore, examined some factors involved in the loss of EBNA-1-specific T cell responses in eBL. T-cell subset frequencies, activation, and IFN-γ- or IL-4-specific responses were analyzed by flow-cytometry. Plasma cytokine levels were measured by ELISA. CD4+ and CD8+ cells in age- and sex-matched healthy controls ( n = 3) expressed more IFN-γ in response to all immunostimulants than in pediatric endemic BL (eBL) patients ( n = 4). In healthy controls, IFN-γ expression was higher than IL-4 expression, whereas in eBL patients the expression of IL-4 by CD4+ cells to EBNA-1 was slightly higher than IFN-γ. Moreover, the blood levels of TNF-α was significantly lower ( p = 0.004) while IL-10 was significantly higher ( p = 0.038), in eBL patients ( n = 21) compared to controls ( n = 16). Additionally, the frequency of CD4+CD25hi+ T cells was higher in both age-matched acute uncomplicated malaria ( n = 26) and eBL ( n = 14) patients compared to healthy controls ( n = 19; p = 0.000 and p = 0.027, respectively). The data suggest that reduced Th1 response in eBL might be due to increased levels of IL-10 and T reg cells.

    Full Text Available The association of lymphoma with necrotic granuloma can pose diagnostic challenges and delay treatment, especially in settings with a high burden of infection. In these settings, the timely use of cytogenetic and molecular methods is most relevant. Here, we report a case of B-cell lymphoma with t (8;14 in a 5-year-old male child. The lymphoma was associated with necrotic granuloma and was initially misdiagnosed as tuberculosis. Polymerase chain reaction was used to detect clonal lymphoproliferation and to rule out Mycobacterium tuberculosis infection. Tumor cells harbored Epstein-Barr virus and expressed CD20, CD10, BCL6, and Ki67 (30%, leading to the diagnosis of B-cell lymphoma with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.

    Full Text Available Objective: Burkitt Lymphoma (BL is a rare and aggressive form of B cell lymphoma that is curable using intensive chemotherapy. Obtaining a complete response (CR at the end of induction chemotherapy is a major prognostic factor. This study retrospectively evaluates the potential impact of 18FDG-PET in the management of children with BL after induction chemotherapy, and the prognostic performance of the Deauville criteria.Methods: 19 children with BL treated according to the French LMB2001 protocol between 2005 and 2012 were included. 18FDG-PET and conventional imaging (CI were performed after induction chemotherapy to confirm CR. 18FDG-PET was interpreted according to Deauville criteria with follow up and/or histology as the gold standard.Results: 18FDG-PET was negative in 15 cases, in agreement with CI in 9/15 cases. The six discordant cases confirmed to be negative by histology, were considered as true negative for 18FDG-PET. Negative predictive value (NPV of CI and 18FDG-PET were 73 and 93% respectively. The five-year PFS was significantly higher in patients with negative 18FDG-PET than those with positive 18FDG-PET (p=0.011. Conclusion: 18FDG-PET interpreted using Deauville criteria can help confirm CR at the end of induction chemotherapy, with a prognostic impact on five-year PFS. Its high NPV could limit the use of residual mass biopsy. Given the small size of our population, these results need to be confirmed by future prospective studies on a larger population.

    Full Text Available Most commonly, histologic transformation (HT from follicular lymphoma (FL manifests as a diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS. Less frequently, HT may result in a high-grade B-cell lymphoma (HGBL with MYC and B-cell lymphoma protein 2 (BCL2 and/or BCL6 gene rearrangements, also known as “double-hit” or “triple-hit” lymphomas. In the 2016 revision of the World Health Organization (WHO classification of lymphoid neoplasms, the category B-cell lymphoma, unclassifiable was eliminated due to its vague criteria and limiting diagnostic benefit. Instead, the WHO introduced the HGBL category, characterized by MYC and BCL2 and/or BCL6 rearrangements. Cases that present as an intermediate phenotype of DLBCL and Burkitt lymphoma (BL will fall within this HGBL category. Very rarely, HT results in both the intermediate DLBCL and BL phenotypes and exhibits lymphoblastic features, in which case the WHO recommends that this morphologic appearance should be noted. In comparison with de novo patients with DLBCL, NOS, those with MYC and BCL2 and/or BCL6 gene rearrangements have a worse prognosis. A 63-year-old woman presented with left neck adenopathy. Laboratory assessments, including complete blood count, complete metabolic panel, serum lactate dehydrogenase, and β 2 -microglobulin, were all normal. A whole-body computerized tomographic (CT scan revealed diffuse adenopathy above and below the diaphragm. An excisional node biopsy showed grade 3A nodular FL. The Ki67 labeling index was 40% to 50%. A bone marrow biopsy showed a small focus of paratrabecular CD20+ lymphoid aggregates. She received 6 cycles of bendamustine (90 mg/m 2 on days +1 and +2 and rituximab (375 mg/m 2 on day +2, with each cycle delivered every 4 weeks.

    The role of protective immunity to Plasmodium falciparum (Pf) malaria in Burkitt lymphoma (BL) is unknown. We investigated the association between BL and antibodies reactive to SE36 antigen, a recombinant protein based on P. falciparum serine repeat antigen 5 gene, targeted by protective malaria immune responses. Cases were children (0-14 years) enrolled at the Korle-Bu Teaching Hospital, Accra, Ghana, during 1965-1994 with BL confirmed by histology or cytology (92% of cases). Controls were apparently healthy children enrolled contemporaneous to the cases from the nearest neighbor house to the case house and were age,- sex-frequency-matched to the cases. Anti-SE36 IgG antibodies were measured using enzyme-linked absorbent immunoassays (ELISAs). SE36 titers were estimated by extrapolating ELISA optical density readings to a standard fitting curve. Anti-SE36 titers were log-transformed for analysis. Odds ratios (ORs) and two-sided 95% confidence intervals (95% CIs) were estimated using unconditional logistic regression. The mean log endpoint dilution titers were 0.63 logs lower in cases than in controls (8.26 [SD 1.68] vs. 8.89 [SD 1.75], Student's t-test, p = 0.019). Lower titers were observed in cases than controls aged 0-4 years (p = 0.05) and in those aged 5-14 years (p = 0.06). Low and medium tertiles of anti-SE36 IgG antibodies were associated with increased OR for BL ([OR 1.67, 95% CI 1.21-2.31] and [OR 1.33, 95% CI 0.96-1.86], respectively, p(trend) = 0.002) in analyses adjusting for age, sex, calendar period and test plate. Our findings suggest that compared to similarly aged children enrolled from the same community, children with BL in Ghana have lower antibodies to SE36 antigen. Copyright © 2011 UICC.

    Full Text Available Abstract Background The overlap in geographical distribution of Plasmodium falciparum malaria and endemic Burkitt's lymphoma (eBL – an aggressive Epstein-Barr virus (EBV-associated B-cell tumour occurring almost exclusively in the tropics – strongly suggests a link between the two diseases. It is suspected that the polyclonal B-cell activation in P. falciparum malaria may precipitate a breakdown in homeostatic T-cell control of EBV-immortalized B-cell proliferation. Previous studies have suggested that a particular T-cell subset, characterized by expression of Vδ1+ γδ T-cell receptors, is important for maintaining B-cell homeostasis, both in P. falciparum- exposed populations and in individuals subject to polyclonal B-cell activation of other aetiology. The objective of the present study was, therefore, to characterize lymphocyte phenotypes and to investigate possible differences in T-cell subset composition and activation status in P. falciparum-exposed Ghanaian children with and without eBL. Methods Venous blood samples in heparin from 21 eBL patients (mean age: 7.0 years; range: 3–11 years, referred to the Burkitt's Tumour Centre at Korle-Bu Teaching Hospital, Accra and 15 healthy, age and sex matched children, were stained with fluorescein isothiocyanate (FITC-, phycoerythrin (PE-, R-phycoerythrin (RPE- and RPE-Cy5-conjugated antibodies (CD3, CD4, CD8, CD25, CD69, CD95, HLA-DR, TCR-γδ, Vδ1, Vδ3, Vγ9 and B-cells and acquired on a flow cytometer. Results A reduction in the proportion of CD3+ cells in eBL patients, due mainly to perturbations among TCR-γδ+ cells was observed. In contrast, the proportions of CD4+ or CD8+ cells were relatively unaffected, as were the mean numbers of peripheral blood mononuclear cells. Conclusion Selective changes in numbers and activation status of TCR-γδ+ cells occurs in Ghanaian children with eBL, a pattern which is similar to P. falciparum-induced changes. The data supports the hypothesis of

    Epstein-Barr virus (EBV) has been linked to malignancies and chronic inflammatory conditions. In this study, EBV detection was compared in children with non-Hodgkin's lymphoma and children with chronic inflammatory conditions, using samples and data from a case-control study carried out at the Mulago National Referral Hospital between 2004 and 2008. EBV viral load was measured in saliva, whole blood and white blood cells by real-time PCR. Serological values for IgG-VCA, EBNA1, and EAd-IgG were compared in non-Hodgkin's lymphoma and chronic inflammatory conditions; and in Burkitt's lymphoma and other subtypes of non-Hodgkin's lymphoma. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated. Of the 127 children included (87 males and 40 females; median age 7 years, range 2-17), 96 had non-Hodgkin's lymphoma (46 Burkitt's lymphoma and 50 other non-Hodgkin's lymphoma), 31 had chronic inflammatory conditions, and only 10% were HIV-positive. The most common clinical presentations for all disease categories considered were fever, night sweats, and weight loss. EBV viral load in whole blood was elevated in Burkitt's lymphoma compared to other non-Hodgkin's lymphoma (OR 6.67, 95% CI 1.32, 33.69; P-value = 0.04), but EBV viral loads in saliva and white blood cells were not different in any of the disease categories considered. A significant difference in EAd-IgG was observed when non-Hodgkin's lymphoma was compared with chronic inflammatory conditions (OR 0.19, 95% CI 0.07, 0.51; P-value = 0.001). When compared to chronic inflammatory conditions, EBV viral load was elevated in Burkitt's lymphoma, and EA IgG was higher in non-Hodgkin's lymphoma. This study supports an association between virological and serological markers of EBV and childhood non-Hodgkin's lymphoma, irrespective of subtype, in Uganda. © 2014 Wiley Periodicals, Inc.

    Expression of the B-cell antigen receptor (BCR) is essential not only for the development but also for the maintenance of mature B cells. Similarly, many B-cell lymphomas, including Burkitt lymphoma (BL), require continuous BCR signaling for their tumor growth. This growth is driven by immunoreceptor tyrosine-based activation motif (ITAM) and PI3 kinase (PI3K) signaling. Here, we employ CRISPR/Cas9 to delete BCR and B-cell co-receptor genes in the human BL cell line Ramos. We find that Ramos B cells require the expression of the BCR signaling component Igβ (CD79b), and the co-receptor CD19, for their fitness and competitive growth in culture. Furthermore, we show that in the absence of any other BCR component, Igβ can be expressed on the B-cell surface, where it is found in close proximity to CD19 and signals in an ITAM-dependent manner. These data suggest that Igβ and CD19 are part of an alternative B-cell signaling module that use continuous ITAM/PI3K signaling to promote the survival of B lymphoma and normal B cells. © 2018 The Authors.

    In B-non-Hodgkin lymphomas, Lyn and Cbp/PAG constitute the core of an oncogenic signalosome that captures the Phosphatidylinositol-3-kinase, the Spleen tyrosine kinase and the Signal transducer and activator of transcription-3 to generate pro-survival and proliferative signals. Lymphoma lines corresponding to follicular, mantle-cell and Burkitt-derived lymphomas display type-specific signalosome organizations that differentially activate PI3K, Syk and STAT3. In the follicular lymphoma line, PI3K, Syk and STAT3 were optimally activated upon association with the Lyn-Cbp/PAG signalosome, while in the Burkitt lymphoma-derived line, the association with Cbp/PAG and activation of PI3K were interfered with by the latent membrane proteins encoded by the Epstein-Barr virus. In the Jeko-1 mantle-cell line, a weak association of Syk with the Lyn-Cbp/PAG signalosome resulted in poor activation of Syk, but in those cells, as in the follicular and Burkitt-derived lines, efficient apoptosis induction by the Syk inhibitor R406 indicated that Syk is nonetheless an important prosurvival element and therefore a valuable therapeutic target. In all configurations described herein is the Lyn-Cbp/PAG signalosome independent of external signals and provides efficient means of activation for its associated lipid and protein kinases. In follicular and Burkitt-derived lines, Syk appears to be activated following binding to Cbp/PAG and no longer requires B-cell receptor-associated activation motifs for activation. Assessment of the different modalities of Lyn-Cbp/PAG signalosome organization could help in selecting the appropriate combination of kinase inhibitors to eliminate a particular type of lymphoma cells.

    Short, intensive cycles of chemotherapy have resulted in improved survival in BurkittOs lymphoma/leukemia (BL) in adults. The prognosis of patients with immunodeficiency virus (HIV)-associated BL is considered to be poor, but these patients have seldom been treated with BL-specific protocols. However, a study (PETHEMA-LAL3/97) in which patients with BL were treated regardless of their HIV status failed to find differences between HIV-infected and immunocompetent individuals. Furthermore, patients who received highly active antiretroviral therapy (HAART) seemed to have a slightly better disease-free survival than those who did not (p=0.051). We extended the follow-up analysis to elucidate the role of HAART in the survival of HIV-infected patients included in the PETHEMA-LAL3/97 protocol.

    Full Text Available Early stage detection of lymphoma cells is invaluable for providing reliable prognosis to patients. However, the purity of lymphoma cells in extracted samples from human patients' marrow is typically low. To address this issue, we report here our work on using optically-induced dielectrophoresis (ODEP force to rapidly purify Raji cells' (a type of Burkitt's lymphoma cell sample from red blood cells (RBCs with a label-free process. This method utilizes dynamically moving virtual electrodes to induce negative ODEP force of varying magnitudes on the Raji cells and RBCs in an optically-induced electrokinetics (OEK chip. Polarization models for the two types of cells that reflect their discriminate electrical properties were established. Then, the cells' differential velocities caused by a specific ODEP force field were obtained by a finite element simulation model, thereby established the theoretical basis that the two types of cells could be separated using an ODEP force field. To ensure that the ODEP force dominated the separation process, a comparison of the ODEP force with other significant electrokinetics forces was conducted using numerical results. Furthermore, the performance of the ODEP-based approach for separating Raji cells from RBCs was experimentally investigated. The results showed that these two types of cells, with different concentration ratios, could be separated rapidly using externally-applied electrical field at a driven frequency of 50 kHz at 20 Vpp. In addition, we have found that in order to facilitate ODEP-based cell separation, Raji cells' adhesion to the OEK chip's substrate should be minimized. This paper also presents our experimental results of finding the appropriate bovine serum albumin concentration in an isotonic solution to reduce cell adhesion, while maintaining suitable medium conductivity for electrokinetics-based cell separation. In short, we have demonstrated that OEK technology could be a promising tool for

    Full Text Available Epstein–Barr virus (EBV is a necessary cause of endemic Burkitt lymphoma (eBL, while the role of Plasmodium falciparum in eBL remains uncertain. This study aimed to generate new hypotheses on the interplay between both infections in the development of eBL by investigating the IgG and IgM profiles against several EBV and P. falciparum antigens. Serum samples collected in a childhood study in Malawi (2005–2006 from 442 HIV-seronegative children (271 eBL cases and 171 controls between 1.4 and 15 years old were tested by quantitative suspension array technology against a newly developed multiplex panel combining 4 EBV antigens [Z Epstein–Barr replication activator protein (ZEBRA, early antigen-diffuse component (EA-D, EBV nuclear antigen 1, and viral capsid antigen p18 subunit (VCA-p18] and 15 P. falciparum antigens selected for their immunogenicity, role in malaria pathogenesis, and presence in different parasite stages. Principal component analyses, multivariate logistic models, and elastic-net regressions were used. As expected, elevated levels of EBV IgG (especially against the lytic antigens ZEBRA, EA-D, and VCA-p18 were strongly associated with eBL [high vs low tertile odds ratio (OR = 8.67, 95% confidence interval (CI = 4.81–15.64]. Higher IgG responses to the merozoite surface protein 3 were observed in children with eBL compared with controls (OR = 1.29, 95% CI = 1.02–1.64, showing an additive interaction with EBV IgGs (OR = 10.6, 95% CI = 5.1–22.2, P = 0.05. Using elastic-net regression models, eBL serological profile was further characterized by lower IgM levels against P. falciparum preerythrocytic-stage antigen CelTOS and EBV lytic antigen VCA-p18 compared with controls. In a secondary analysis, abdominal Burkitt lymphoma had lower IgM to EBV and higher IgG to EA-D levels than cases with head involvement. Overall, this exploratory study confirmed the strong role of EBV in eBL and identified

    Dual-targeted therapy has been shown to be a promising treatment option in recurrent and/or refractory B-cell non-Hodgkin's lymphoma (B-NHL). We generated radioimmunoconjugates (RICs) comprising either a novel humanized anti-CD22 monoclonal antibody, huRFB4, or rituximab, and the low-energy β-emitter {sup 177}Lu. Both RICs were evaluated as single agents in a human Burkitt's lymphoma xenograft mouse model. To increase the therapeutic efficacy of the anti-CD22 RIC, combination therapy with unlabelled anti-CD20 rituximab was explored. The binding activity of CHX-A''-DTPA-conjugated antibodies to target cells was analysed by flow cytometry. To assess tumour targeting of {sup 177}Lu-labelled antibodies, in vivo biodistribution experiments were performed. For radioimmunotherapy (RIT) studies, non-obese diabetic recombination activating gene-1 (NOD-Rag1{sup null}) interleukin-2 receptor common gamma chain (IL2r γ {sup null}) null mice (NRG mice) were xenografted subcutaneously with Raji Burkitt's lymphoma cells. {sup 177}Lu-conjugated antibodies were administered at a single dose of 9.5 MBq per mouse. For dual-targeted therapy, rituximab was injected at weekly intervals (0.5 - 1.0 mg). Tumour accumulation of RICs was monitored by planar scintigraphy. Conjugation of CHX-A''-DTPA resulted in highly stable RICs with excellent antigen-binding properties. Biodistribution experiments revealed higher tumour uptake of the {sup 177}Lu-labelled anti-CD22 IgG than of {sup 177}Lu-labelled rituximab. Treatment with {sup 177}Lu-conjugated huRFB4 resulted in increased tumour growth inhibition and significantly longer survival than treatment with {sup 177}Lu-conjugated rituximab. The therapeutic efficacy of the anti-CD22 RIC could be markedly enhanced by combination with unlabelled rituximab. These findings suggest that dual targeting with {sup 177}Lu-based CD22-specific RIT in combination with rituximab is a promising new treatment option for

    Full Text Available Non-Hodgkin lymphomas (NHL are a heterogeneous group of hematologic malignancies typically treated with multiagent chemotherapy. Rarely, spontaneous remissions can be observed, particularly in more indolent subtypes. The prognosis of aggressive NHL can be predicted using clinical and histopathologic factors. In aggressive B-cell NHL, the importance of MYC and BCL2 proto-oncogene coexpression (as assessed by immunohistochemistry and high-grade histologic features are particularly noteworthy. We report a unique case of spontaneous remission in a patient with an aggressive B-cell NHL which harbored high-risk histopathologic features, including MYC protein expression at 70–80%, BCL2 protein expression, and morphologic features suggestive of high-grade B-cell lymphoma, NOS (formerly B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma [BCLU]. After undergoing a biopsy to confirm this diagnosis, he opted to forego curative-intent chemotherapy. The single, yet relatively large area of involvement noted on 18F-fluorodeoxyglucose positron emission tomography-computed tomography steadily resolved on subsequent follow-up studies. He remained without evidence of recurrence one year later, having never received treatment. This case emphasizes the potential for spontaneous remission in NHL and demonstrates that this phenomenon can be observed despite contemporary high-risk histopathologic features.

    Approximately 10% of cases of diffuse large B cell lymphoma (DLBCL) harbor a MYC rearrangement and this has been associated with an inferior outcome following standard therapy across many different studies. Double-hit and triple-hit lymphomas harbor concurrent rearrangements of MYC and BCL2 and/or BCL6 and are also associated with a very aggressive course and poor clinical outcome. It is unclear and there is lack of consensus on how these diseases should be approached therapeutically. They are characterized typically by high tumor proliferation and likely require Burkitt lymphoma-type strategies and several retrospective studies suggest that more intensive approaches than rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) may be beneficial. One challenge in this respect is that most patients with these diseases are older than 60 years and generally have poor tolerability of regimens typically used in Burkitt lymphoma. Dose-adjusted EPOCH-R is an alternative effective immunochemotherapy platform for DLBCL and is effective in Burkitt lymphoma, and retrospective studies suggest that it is effective and feasible in patients with DLBCL that harbors a MYC rearrangement with or without a BCL-2 translocation (double-hit). A multicenter study of this approach in MYC-rearranged DLBCL is ongoing and preliminary results are very encouraging. There is a lack of consensus on the role of consolidation stem cell transplantation in patients who achieve a good response to initial therapy but at this point in time, no (retrospective) studies have demonstrated any benefit. These diseases are also associated with a high rate of CNS involvement and progression and checking for cerebrospinal fluid by cytology and flow cytometry at initial diagnosis should be considered. In summary, based on retrospective data and preliminary prospective data (as more mature data is awaited), while Burkitt-type regimens may be feasible in young patients, DA-EPOCH-R is a

    Full Text Available There is warranted interest in assessing the association between residential radon exposure and the risk of childhood cancer. We sought to evaluate the association between residential radon exposure and the incidence of childhood lymphoma in Texas. The Texas Cancer Registry (n = 2147 provided case information for the period 1995–2011. Denominator data were obtained from the United States Census. Regional arithmetic mean radon concentrations were obtained from the Texas Indoor Radon Survey and linked to residence at diagnosis. Exposure was assessed categorically: ≤25th percentile (reference, >25th to ≤50th percentile, >50th to ≤75th percentile, and >75th percentile. Negative binomial regression generated adjusted incidence rate ratios (aIRR and 95% confidence intervals (CI. We evaluated lymphoma overall and by subtype: Hodgkin (HL; n = 1248, Non-Hodgkin excluding Burkitt (non-BL NHL; n = 658, Burkitt (BL; n = 241, and Diffuse Large B-cell (DLBCL; n = 315. There was no evidence that residential radon exposure was positively associated with lymphoma overall, HL, or BL. Areas with radon concentrations >75th percentile had a marginal increase in DLBCL incidence (aIRR = 1.73, 95% CI: 1.03–2.91. In one of the largest studies of residential radon exposure and the incidence of childhood lymphoma, we found little evidence to suggest a positive or negative association; an observation consistent with previous studies.

    Outcome of HIV-infected patients with AIDS-related lymphomas has improved during recent years. However, data on incidence, risk factors, and outcome of relapses in AIDS-related lymphomas after achieving complete remission are still limited. This prospective observational multicenter study includes HIV-infected patients with biopsy- or cytology-proven malignant lymphomas since 2005. Data on HIV infection and lymphoma characteristics, treatment and outcome were recorded. For this analysis, AIDS-related lymphomas patients in complete remission were analyzed in terms of their relapse- free survival and potential risk factors for relapses. In total, 254 of 399 (63.7%) patients with AIDS-related lymphomas reached a complete remission with their first-line chemotherapy. After a median follow up of 4.6 years, 5-year overall survival of the 254 patients was 87.8% (Standard Error 3.1%). Twenty-nine patients relapsed (11.4%). Several factors were independently associated with a higher relapse rate, including an unclassifiable histology, a stage III or IV according to the Ann Arbor Staging System, no concomitant combined antiretroviral therapy during chemotherapy and R-CHOP-based compared to more intensive chemotherapy regimens in Burkitt lymphomas. In conclusion, complete remission and relapse rates observed in our study are similar to those reported in HIV-negative non-Hodgkin lymphomas. These data provide further evidence for the use of concomitant combined antiretroviral therapy during chemotherapy and a benefit from more intensive chemotherapy regimens in Burkitt lymphomas. Modifications to the chemotherapy regimen appear to have only a limited impact on relapse rate. Copyright © 2018 Ferrata Storti Foundation.

    High-grade B-cell lymphomas with MYC, BCL2, and BCL6 rearrangements (triple hit lymphoma) are uncommon. We studied the clinicopathologic features of 40 patients with triple hit lymphoma and compared them to 157 patients with MYC/BCL2 double hit lymphoma and 13 patients with MYC/BCL6 double hit lymphoma. The triple hit lymphoma group included 25 men and 15 women with a median age of 61 years (range, 34-85). Nine patients had a history of B-cell lymphoma. Histologically, 23 (58%) cases were diffuse large B-cell lymphoma and 17 cases had features of B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma. Most cases of triple hit lymphoma were positive for CD10 (100%), BCL2 (95%), BCL6 (82%), MYC (74%), and 71% with MYC and BCL2 coexpression. P53 was overexpressed in 29% of triple hit lymphoma cases. The clinicopathological features of triple hit lymphoma patients were similar to patients with MYC/BCL2 and MYC/BCL6 double hit lymphoma, except that triple hit lymphoma cases were more often CD10 positive compared with MYC/BCL6 double hit lymphoma (p hit lymphoma and double hit lymphoma and overall survival in triple hit lymphoma patients was 17.6 months, similar to the overall survival of patients with double hit lymphoma (p = 0.67). Patients with triple hit lymphoma showing P53 overexpression had significantly worse overall survival compared with those without P53 overexpression (p = 0.04). On the other hand, double expressor status and prior history of B-cell lymphoma did not correlate with overall survival. In conclusion, most patients with triple hit lymphoma have an aggressive clinical course and poor prognosis and these tumors have a germinal center B-cell immunophenotype, similar to patients with double hit lymphomas. P53 expression is a poor prognostic factor in patients with triple hit lymphoma.

    2012-01-01

    Full Text Available Certain infectious agents are associated with lymphomas, but the strength of the association varies geographically, suggesting that local environmental factors make important contributions to lymphomagenesis. Endemic Burkitt’s Lymphoma has well-defined environmental requirements making it particularly suitable for research into local environmental factors. The Epstein-Barr virus and holoendemic Malaria are recognized as important cofactors in endemic Burkitt’s Lymphoma and their contributions are discussed. Additionally, infection with Chikungunya Fever, a potentially oncogenic arbovirus, was associated with the onset of endemic Burkitt’s Lymphoma in one study and also with space-time case clusters of the lymphoma. Chikungunya Virus has several characteristics typical of oncogenic viruses. The Flavivirus, Hepatitis C, a Class 1 Human Carcinogen, closely related to the arboviruses, Yellow Fever, and Dengue, is also more distantly related to Chikungunya Virus. The mechanisms of oncogenesis believed to operate in Hepatitis C lymphomagenesis are discussed, as is their potential applicability to Chikungunya Virus.

    Burkitt lymphoma (BL) is a malignant disease, which is frequently found in areas with holoendemic Plasmodium falciparum malaria. We have previously found that the VAR2CSA protein is present on malaria-infected erythrocytes and facilitates a highly specific binding to the placenta. OfCS is absent from other non-malignant tissues and thus VAR2CSA generally facilitates parasite sequestration and accumulation in pregnant women. In this study, we show that the specific receptor for VAR2CSA, the oncofetal chondroitin sulfate (ofCS), is likewise present in BL tissue and cell lines. We therefore explored whether ofCS in BL could act as anchor-site for VAR2CSA-expressing infected erythrocytes. In contrast to the placenta, we found no evidence of in vivo sequestering of infected erythrocytes in the BL tissue. Furthermore, we found VAR2CSA specific antibody titers in children with endemic BL to be lower than in control children from the same malaria endemic region. The abundant presence of ofCS in BL tissue and the absence of ofCS in non-malignant tissue, encouraged us to examine whether recombinant VAR2CSA could be used to target BL. We confirmed the binding of VAR2CSA to BL-derived cells and showed that a VAR2CSA drug conjugate efficiently killed the BL-derived cell lines in vitro. These results identify ofCS as a novel therapeutic BL target and highlight how VAR2CSA could be used as a tool for the discovery of novel approaches for directing BL therapy. PMID:27997697

    Endemic Burkitt lymphoma (eBL) is linked to Plasmodium falciparum (Pf) infection geographically, but evidence from individual-level studies is limited. We investigated this issue among 354 childhood eBL cases and 384 age-, sex-, and location-matched controls enrolled in Ghana from 1965 to 1994. Immunoglobulin G1 (IgG1) and immunoglobulin G3 (IgG3) antibodies to antigens diagnostic of recent infection Pf histidine-rich protein-II (HRP-II) and 6NANP, Pf-vaccine candidates SE36 and 42-kDa region of the 3D7 Pf merozoite surface protein-1 (MSP-1), and tetanus toxoid were measured by indirect enzyme-linked immunoassay. Odds ratios (ORs) and 95% confidence intervals (CIs) for association with eBL were estimated using unconditional logistic regression. After adjustments, eBL was positively associated with HRP-IIIgG3 seropositivity (adjusted OR: 1.60; 95% CI 1.08-2.36) and inversely associated with SE36IgG1 seropositivity (adjusted OR: 0.37; 95% CI 0.21-0.64) and with tetanus toxoidIgG3 levels equal or higher than the mean (adjusted OR: 0.46; 95% CI 0.32-0.66). Anti-MSP-1IgG3 and anti-6NANPIgG3 were indeterminate. eBL risk was potentially 21 times higher (95% CI 5.8-74) in HRP-IIIgG3-seropositive and SE36IgG1-seronegative responders compared with HRP-IIIgG3-seronegative and SE36IgG1-seropositive responders. Our results suggest that recent malaria may be associated with risk of eBL but long-term infection may be protective.

  3. Upregulation of the Chemokine Receptor CCR2B in Epstein‒Barr Virus-Positive Burkitt Lymphoma Cell Lines with the Latency III Program

    Full Text Available CCR2 is the cognate receptor to the chemokine CCL2. CCR2–CCL2 signaling mediates cancer progression and metastasis dissemination. However, the role of CCR2–CCL2 signaling in pathogenesis of B-cell malignancies is not clear. Previously, we showed that CCR2B was upregulated in ex vivo peripheral blood B cells upon Epstein‒Barr virus (EBV infection and in established lymphoblastoid cell lines with the EBV latency III program. EBV latency III is associated with B-cell lymphomas in immunosuppressed patients. The majority of EBV-positive Burkitt lymphoma (BL tumors are characterized by latency I, but the BL cell lines drift towards latency III during in vitro culture. In this study, the CCR2A and CCR2B expression was assessed in the isogenic EBV-positive BL cell lines with latency I and III using RT-PCR, immunoblotting, and immunostaining analyses. We found that CCR2B is upregulated in the EBV-positive BL cells with latency III. Consequently, we detected the migration of latency III cells toward CCL2. Notably, the G190A mutation, corresponding to SNP CCR2-V64I, was found in one latency III cell line with a reduced migratory response to CCL2. The upregulation of CCR2B may contribute to the enhanced migration of malignant B cells into CCL2-rich compartments.

    Three exceptional cell lines have been tested for the presence of the Epstein-Barr virus genome by nucleic acid hybridization (complementary RNA·DNA) and Epstein-Barr virus-determined nuclear antigen tests. Two lines were derived from Swedish lymphoma cases and one from an African Burkitt-like lymphoma biopsy that was negative for Epstein-Barr virus DNA and the virus-determined nuclear antigen. All three lines apparently lacked the viral genome. Two of the three lines clearly had characteristics of B-cells (bone-marrow-derived). PMID:4369887

    The diagnostic criteria have been defined based on the tools that the country has acquired and international guidelines for pure entities: the LB, LDCGB, and the new entity of B lymphoma unclassifiable with features intermediate LDCGB and LB. The fluorescence in situ hybridization for the translocation (8;14) has been implemented in paraffin tissues for proper categorization. A total of 21 cases have been studied: the characteristics of patients, morphology, immunohistochemistry and the presence or absence of the translocation (8;14). Twelve of the cases have been classified as B-cell lymphoma unclassifiable with features intermediate between LDCGB and LB. Furthermore, nine of the cases were classified in LB. Fluorescence in situ hybridization (FISH) has been negative in 5 of the 21 cases. The diagnosis of lymphoma with features bordering between the LB and the LDCGB has been imperative for the survival of the patient and the corresponding treatment [es

    Plasmodium falciparum (Pf) malaria infection is suspected to cause endemic Burkitt Lymphoma (eBL), but the evidence remains unsettled. An inverse relationship between sickle cell trait (SCT) and eBL, which supports that between malaria and eBL, has been reported before, but in small studies with low power. We investigated this hypothesis in children in a population-based study in northern Uganda using Mendelian Randomization. Malaria-related polymorphisms (SCT, IL10, IL1A, CD36, SEMA3C, and IFNAR1) were genotyped in 202 eBL cases and 624 controls enrolled during 2010-2015. We modeled associations between genotypes and eBL or malaria using logistic regression. SCT was associated with decreased risk of eBL (adjusted odds ratio [OR] 0·37, 95% CI 0·21-0·66; p=0·0003). Decreased risk of eBL was associated with IL10 rs1800896-CT (OR 0·73, 95% CI 0·50-1·07) and -CC genotypes (OR 0·53, 95% CI 0·29-0·95, p trend =0·019); IL1A rs2856838-AG (OR 0·56, 95% CI 0·39-0·81) and -AA genotype (OR 0·50, 95% CI 0·28-1·01, p trend =0·0016); and SEMA3C rs4461841-CT or -CC genotypes (OR 0·57, 95% CI 0·35-0·93, p=0·0193). SCT and IL10 rs1800896, IL1A rs2856838, but not SEMA3C rs4461841, polymorphisms were associated with decreased risk of malaria in the controls. Our results support a causal effect of malaria infection on eBL. Published by Elsevier B.V.

    The effects of splenectomy and/or whole-body irradiation of nude mice before xenotransplantation of lymphoid cell lines, lymphoma, and leukemia were studied. Transplantation after whole-body irradiation resulted in the increased ''take'' rate of three cultured cell lines (two of T-cell-derived acute lymphocytic leukemia and one of B-cell derived acute lymphocytic leukemia) and in the tumorous growth of Burkitt-derived Raji and spontaneously transformed lymphoblastoid cell lines. With splenectomy plus irradiation as a pretreatment, tumorous growth occurred in four other cell lines which were not transplantable after irradiation only (two cell lines of Epstein-Barr virus-transformed cord blood cells and one each of null acute lymphocytic leukemia and nodular lymphoma-derived cell lines). Direct transplantation of leukemia and lymphoma cells into the pretreated mice was successful in 7 of 24 cases (29%). B-cell-derived diffuse large lymphoid lymphoma was transplantable in three of seven cases (43%). However, lymphoma and leukemia of peripheral T-cell origin was difficult to transplant even with pretreatment, and only one pleomorphic T-cell lymphoma grew to a significant size (2 cm). One tumor each of B-cell-derived diffuse large lymphoid and T-cell diffuse lymphoblastic lymphoma became transplantable

    Central nervous system (CNS) involvement by lymphoma is a complication associated, almost invariably, with a poor prognosis. The knowledge of the risk factors for CNS relapse is important to determine which patients could benefit from prophylaxis. Thus, patients with very aggressive lymphomas (such as lymphoblastic lymphoma or Burkitt's lymphoma) must systematically receive CNS prophylaxis due to a high CNS relapse rate (25-30%), while in patients with indolent lymphoma (such as follicular lymphoma or marginal lymphoma) prophylaxis is unnecessary. However, the question about CNS prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the most common type of lymphoma, remains controversial. The information available is extensive, mainly based on retrospective and heterogeneous studies. There seems that immunochemotherapy based on rituximab reduces the CNS relapse rate. On the other hand, patients with increased serum lactate dehydrogenase plus more than one extranodal involvement seem to have a higher risk of CNS relapse, but a prophylaxis strategy based only on the presence of these 2 factors does not prevent all CNS relapses. Patients with involvement of testes or breast have high risk of CNS relapse and prophylaxis is mandatory. Finally, CNS prophylaxis could be considered in patients with DLBCL and renal or epidural space involvement, as well as in those cases with MYC rearrangements, although additional studies are necessary.

    Epstein-Barr virus (EBV), originally discovered through its association with Burkitt lymphoma, is now aetiologically linked to a remarkably wide range of lymphoproliferative lesions and malignant lymphomas of B-, T- and NK-cell origin. Some occur as rare accidents of virus persistence in the B lymphoid system, while others arise as a result of viral entry into unnatural target cells. The early finding that EBV is a potent B-cell growth transforming agent hinted at a simple oncogenic mechanism by which this virus could promote lymphomagenesis. In reality, the pathogenesis of EBV-associated lymphomas involves a complex interplay between different patterns of viral gene expression and cellular genetic changes. Here we review recent developments in our understanding of EBV-associated lymphomagenesis in both the immunocompetent and immunocompromised host.This article is part of the themed issue 'Human oncogenic viruses'. © 2017 The Authors.

    Deregulated Myc expression drives many human cancers, including Burkitt's lymphoma and a highly aggressive subset of diffuse large cell lymphomas. Myc-driven tumors often display resistance to chemotherapeutics because of acquisition of mutations that impair the apoptosis pathway regulated by the Bcl-2 protein family. Given the need to identify new therapies for such lymphomas, we have evaluated the efficacy of ABT-737, a small molecule that mimics the action of the BH3-only proteins, natural...

    Computed tomography is currently the method of choice for the diagnostic and staging of lymphomas. Computed tomography enables accurate measurements of both tumor extent and volume and provides information that can be used to plan an appropriate strategy for the treatment. The purpose of the present article is to describe and analyze the chest and abdomen computed tomography and ultrasound findings in HIV-negative patients with lymphoma. Clinical abnormalities, such as the reason the patient sought medical assistance already showing evidence of lymphocytic disease (not yet diagnosed at this point) and the physical examination abnormalities seen on the first consultation were also studied. This study comprised 30 patients: 40% with non-Hodgkin lymphoma, 46,6% with Hodgkin lymphoma, 10% with Burkitt's lymphoma and 3,3% with lymphoblastic lymphoma. (author)

    Burkitt lymphoma (BL), the most common pediatric cancer in sub-Saharan Africa, is a malignancy of antigen-experienced B lymphocytes. High-throughput sequencing (HTS) of the immunoglobulin heavy ( IGH ) and light chain ( IGK / IGL ) loci was performed on genomic DNA from 51 primary BL tumors: 19 from Uganda and 32 from Ghana. Reverse transcription polymerase chain reaction analysis and tumor RNA sequencing (RNAseq) was performed on the Ugandan tumors to confirm and extend the findings from the HTS of tumor DNA. Clonal IGH and IGK / IGL rearrangements were identified in 41 and 46 tumors, respectively. Evidence for rearrangement of the second IGH allele was observed in only 6 of 41 tumor samples with a clonal IGH rearrangement, suggesting that the normal process of biallelic IGHD to IGHJ diversity-joining (DJ) rearrangement is often disrupted in BL progenitor cells. Most tumors, including those with a sole dominant, nonexpressed DJ rearrangement, contained many IGH and IGK / IGL sequences that differed from the dominant rearrangement by < 10 nucleotides, suggesting that the target of ongoing mutagenesis of these loci in BL tumor cells is not limited to expressed alleles. IGHV usage in both BL tumor cohorts revealed enrichment for IGHV genes that are infrequently used in memory B cells from healthy subjects. Analysis of publicly available DNA sequencing and RNAseq data revealed that these same IGHV genes were overrepresented in dominant tumor-associated IGH rearrangements in several independent BL tumor cohorts. These data suggest that BL derives from an abnormal B-cell progenitor and that aberrant mutational processes are active on the immunoglobulin loci in BL cells.

    2014-03-01

    Full Text Available Three cases of Epstein-Barr virus (EBV-negative post-transplant lymphoproliferative disease that occurred 6 to 8 years after renal transplantation are reported. The patients respectively had gastric mucosa-associated lymphoid tissue lymphoma, gastric diffuse large B-cell lymphoma, and atypical Burkitt lymphoma. Absence of EBV in the tissue samples was demonstrated by both in situ hybridization for EBV early RNA and polymerase chain reaction for EBV DNA. Patients were treated with reduction in immunosuppression and combined chemotherapy plus an anti-CD20 monoclonal antibody, rituximab. Despite the reduction in immunosuppression, patients had stable renal functions without loss of graft functions. The patient with atypical Burkitt lymphoma had an abnormal karyotype, did not respond to treatment completely, and died due to disease progression. The other patients are still alive and in remission 5 and 3 years after diagnosis, respectively. EBV-negative post-transplant lymphoproliferative diseases are usually late-onset and are reported to have poor prognosis. Thus, reduction in immunosuppression is usually not sufficient for treatment and more aggressive approaches like rituximab with combined chemotherapy are required.

    To describe the patient demographics and outcome analysis in paediatric non-Hodgkin lymphoma (NHL) patients. Study Design:An observational study. Place and Duration of Study:The Hematology/Oncology Unit of The Children's Hospital and Institute of Child Health, Lahore, from January 2012 till December 2014. Methodology:Demographics including age, gender, histopathology, stage and outcome data, in biopsy proven NHL patients were analyzed. Burkitts/B Cell and Diffuse Large B Cell lymphoma patients were treated with MCP 842 Protocol while T/B-cell lymphoblastic lymphoma (LL) patients were treated with EURO-LB 02 protocol. Results:Ninety-one patients were treated during the study period at CHL. Data was insufficient in 18 patients, so they were excluded from the study. Patients included were 73. Males were 53 (72.6%). Thirty-seven (50.7%) were 5-10 years of age, and 22 (30.1%) 10-16 years old. Abdominal mass was the commonest presentation seen in 32 (43.8%), lymphadenopathy in 27 (37%), intussusception in 5 (6.8%), while intestinal obstruction, obstructive uropathy, nasopharyngeal mass, gastric mass, primary bone lymphoma, pericardial effusion, jaw swelling, cheek swelling and paraspinal mass present in one (1%) each. Histopathological subtypes consist of Burkitt's lymphoma (BL) in 32 (43.8%), B cell NHL in 10 (13.7%), lymphoblastic lymphoma (LL) in 26 (35.6%), diffuse large B cell lymphoma (DLBCL) in 2 (2.8%), and anaplastic large cell lymphoma (ALCL) in 1 (1.4%). Sixty-seven (91%) presented in stage III, and six (8.4%) in stage IV. Forty-eight (65.8%) patients had completed treatment and are well to date, 16 (21.9%) died, 5 (6.8%) left against medical advice (LAMA), and 4 (5.5%) patients relapsed. Conclusion:Burkitt's lymphoma was the commonest type of NHL seen in this cohort that predominantly presented with an abdominal mass. Children usually presented in advanced stage with delayed diagnosis. Better supportive care can improve the prognosis

    Epstein Barr virus (EBV) sequence variation is thought to contribute to Burkitt lymphoma (BL), but lack of data from primary BL tumors hampers efforts to test this hypothesis. We directly sequenced EBV from 12 BL biopsies from Ghana, Brazil, and Argentina, aligned the obtained reads to the wild-type (WT) EBV reference sequence, and compared them with 100 published EBV genomes from normal and diseased people from around the world. The 12 BL EBVs were Type 1. Eleven clustered close to each other and to EBV from Raji BL cell line, but away from 12 EBVs reported from other BL-derived cell lines and away from EBV from NPC and healthy people from Asia. We discovered 23 shared novel nucleotide-base changes in the latent membrane protein (LMP)-1 promoter and gene (associated with 9 novel amino acid changes in the LMP-1 protein) of the 11 BL EBVs. Alignment of this region for the 112 EBV genomes revealed four distinct patterns, tentatively termed patterns A to D. The distribution of BL EBVs was 48%, 8%, 24% and 20% for patterns A to D, respectively; the NPC EBV's were Pattern B, and EBV-WT was pattern D. Further work is needed to investigate the association between EBV LMP-1 patterns with BL.

    The authors show that endemic (eBL), sporadic (sBL), and acquired immunodeficiency syndrome-associated (AIDS-BL) forms of Burkitt lymphoma (BL) carrying t(8; 14) chromosomal translocations display different breakpoints within the immunoglobulin heavy-chain locus (IGH) on chromosome 14. In sBL (7 out of 11) and AIDS-BL (5 out of 6), the breakpoints occurred within or near the IGH ..mu.. switch (S/sub mu/) region on chromosome 14 and within the c-myc locus (MYC) on chromosome 8. In most eBL (13 out of 16) the breakpoints were mapped within or 5' to the IGH joining J/sub H/ region on chromosome 14 and outside the MYC locus on chromosome 8. Cloning and sequencing of the (8; 14) chromosomal junctions from two eBL cell lines and one eBL biopsy sample show that the recombination do not involve IGH-specific recombination signals on chromosome 14 or homologous sequences on chromosome 8, suggesting that these events are not likely to be mediated by the same mechanisms or enzymes as in IGH rearrangements. In general, these data have implications for the timing of occurrence of chromosomal translocations during B-cell differentiation in different BL types.

    Full Text Available We describe the case a spinal cord localization of neurological toxoplasmosis in a HIV-positive patient with Burkitt lymphoma, previously treated with chemotherapy and immunotherapy. This complication occurred while patient was in complete remission of lymphoma, with CD4+ T cell count of 270 /ml, undetectable HIV viremia, and despite the trimethoprim/ sulfamethoxazole prophylaxis. Indeed, we hypothesize that in our patient neurologic toxoplasmosis has been fostered more by previous immuno-chemotherapy than by HIV- related immunodeficiency. On the whole, this case suggests that parameters usually employed to predict the risk for opportunistic infections in HIV-positive people might not apply to patients with HIV-related lymphomas.

    Similar to resting mature B cells, where the B-cell antigen receptor (BCR) controls cellular survival, surface BCR expression is conserved in most mature B-cell lymphomas. The identification of activating BCR mutations and the growth disadvantage upon BCR knockdown of cells of certain lymphoma entities has led to the view that BCR signalling is required for tumour cell survival. Consequently, the BCR signalling machinery has become an established target in the therapy of B-cell malignancies. Here we study the effects of BCR ablation on MYC-driven mouse B-cell lymphomas and compare them with observations in human Burkitt lymphoma. Whereas BCR ablation does not, per se, significantly affect lymphoma growth, BCR-negative (BCR - ) tumour cells rapidly disappear in the presence of their BCR-expressing (BCR + ) counterparts in vitro and in vivo. This requires neither cellular contact nor factors released by BCR + tumour cells. Instead, BCR loss induces the rewiring of central carbon metabolism, increasing the sensitivity of receptor-less lymphoma cells to nutrient restriction. The BCR attenuates glycogen synthase kinase 3 beta (GSK3β) activity to support MYC-controlled gene expression. BCR - tumour cells exhibit increased GSK3β activity and are rescued from their competitive growth disadvantage by GSK3β inhibition. BCR - lymphoma variants that restore competitive fitness normalize GSK3β activity after constitutive activation of the MAPK pathway, commonly through Ras mutations. Similarly, in Burkitt lymphoma, activating RAS mutations may propagate immunoglobulin-crippled tumour cells, which usually represent a minority of the tumour bulk. Thus, while BCR expression enhances lymphoma cell fitness, BCR-targeted therapies may profit from combinations with drugs targeting BCR - tumour cells.

    Full Text Available A 93-year-old female was transferred to the emergency ward of our hospital due to disturbance of consciousness and hypotension. Computed tomography showed bilateral pleural and pericardial effusion without evidence of tumor masses or lymphadenopathy. Cytodiagnosis of pleural effusion revealed proliferation of atypical lymphoid-like cells with pan-B surface markers. We suspected primary effusion lymphoma-like lymphoma; however, the monoclonality of these cells was not confirmed. Cytodiagnosis of bone marrow revealed lymphoma cells with monoclonal B-cell markers. These findings prompted a diagnosis of diffuse large B-cell lymphoma with bone marrow invasion. In the case of pericardial or pleural effusion, clinicians should consider carefully both hematological malignancy and its classification.

    Full Text Available Latent EBV infection is associated with several malignancies, including EBV post-transplant lymphoproliferative disorders (LPD, Hodgkin and non-Hodgkin lymphomas, nasopharyngeal carcinoma and Burkitt lymphoma. The range of expression of latent EBV antigens varies in these tumors, which influences how susceptible the tumors are to immunotherapeutic approaches. Tumors expressing type III latency, such as in LPD, express the widest array of EBV antigens making them the most susceptible to immunotherapy. Treatment strategies for EBV-related tumors include restoring normal cellular immunity by adoptive immunotherapy with EBV-specific T cells and targeting the malignant B cells with monoclonal antibodies. We review the current immunotherapies and future studies aimed at targeting EBV antigen expression in these tumors.

    Full Text Available Abstract Introduction Discordant lymphomas are rare entities characterized by the simultaneous presence of two distinct types of lymphomas in different anatomic sites. We describe a very rare case of simultaneous occurrence of splenic mantle cell lymphoma and marginal zone lymphoma involving the bone marrow and peripheral blood. Case presentation We report the case of a 60-year-old asymptomatic Caucasian woman in whom discordant lymphomas were discovered when a slight lymphocytosis and a conspicuous splenomegaly were observed. The different morphological, immunophenotypical and immunohistochemical features found in the different pathologic samples obtained from peripheral blood, bone marrow and spleen sections made it possible to differentiate two types of non-Hodgkin B-cell lymphomas: a mantle cell lymphoma infiltrating the spleen and a marginal zone lymphoma involving both the bone marrow and peripheral blood. Since a similar IgH gene rearrangement was found both in the bone marrow and in the spleen, the hypothesis of a common origin, followed by a different clonal selection of the neoplastic lymphocytes may be taken into consideration. Conclusion Our case emphasizes the usefulness of investigating simultaneous specimens from different anatomic sites from the same patient and the relevant diagnostic role of splenectomy.

    Full Text Available Data supporting the role of radiotherapy in secondary trigeminal nerve lymphoma is scarce. Here, I report the case of 64-year-old Thai male diagnosed as gastric diffuse large B cell lymphoma with secondary trigeminal nerve lymphoma. He had previously received one cycle of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP, followed by five cycles of rituximab plus CHOP (R-CHOP with intrathecal methotrexate (MTX and cytarabine (Ara-C. One month after the last cycle of R-CHOP, he developed a headache and numbness on the left side of his face. MRI revealed thickening of the left trigeminal nerve. He received one intrathecal injection of MTX and Ara-C, followed by systemic chemotherapy. After receiving intrathecal chemotherapy, his symptoms disappeared. Clinical response and MRI studies suggested secondary trigeminal nerve lymphoma. Two months later, our patient’s secondary trigeminal nerve lymphoma had progressed. Salvage whole brain irradiation (36 Gy with boost dose (50 Gy along the left trigeminal nerve was given. Unfortunately, our patient developed heart failure and expired during the radiotherapy session. In conclusion and specific to secondary central nervous system lymphoma (SCNSL, radiotherapy may benefit patients who fail to respond to systemic chemotherapy and palliative treatment. The results this report fail to support the role of radiotherapy in secondary trigeminal nerve lymphoma.

    The role of radiotherapy in the treatment of nodal non-Hodgkin's lymphoma has been modified by the introduction of efficient chemotherapy and the development of different pathological classifications. The recommended treatment of early-stage aggressive lymphomas is primarily a combination chemotherapy. The interest of adjuvant radiotherapy remains unclear and has to be established through large prospective trials. If radiation therapy has to be delivered, the historical results of exclusive radiation therapy showed that involved-fields and a dose of 35-40 Gy (daily fraction of 1.8 Gy, 5 days a week) are the optimal schedule. The interest of radiotherapy in the treatment of advanced-stage aggressive lymphoma is yet to be proven. Further studies had to stratify localized stages according to the factors of the International Prognostic Index. For easy-stage low-grade lymphoma, radiotherapy remains the standard treatment. However, the appropriate technique to use is controversial. Involved-field irradiation at a dose of 35 Gy seems to be the optimal schedule, providing a 10 year disease-free survival rate of 50 % and no major toxicity. There is no standard indication of radiotherapy in the treatment advanced-stage low-grade lymphoma. For 'new' nodal lymphoma's types, the indication of radiotherapy cannot be established (mantle-zone lymphoma, marginal zone B-cell lymphoma) or must take into account the natural history (Burkitt's lymphoma, peripheral T-cell lymphoma) and the sensibility to others therapeutic methods.

    Full Text Available Abstract Introduction Mucosa associated lymphoid tissue lymphomas are the most common lymphomas of the salivary glands. The benign lymphoepithelial lesion is also a lymphoproliferative disease that develops in the parotid gland. In the present case report, we describe one case of benign lymphoepithelial lesion with a subsequent low transformation to grade mucosa associated lymphoid tissue lymphoma appearing as a cystic mass in the parotid gland. Case presentation A 78-year-old Caucasian female smoker was referred to our clinic with a non-tender left facial swelling that had been present for approximately three years. The patient underwent resection of the left parotid gland with preservation of the left facial nerve through a preauricular incision. The pathology report was consistent with a low-grade marginal-zone B-cell non-Hodgkin lymphoma (mucosa associated lymphoid tissue lymphoma following benign lymphoepithelial lesion of the gland. Conclusions Salivary gland mucosa associated lymphoid tissue lymphoma should be considered in the differential diagnosis of cystic or bilateral salivary gland lesions. Parotidectomy is recommended in order to treat the tumor and to ensure histological diagnosis for further follow-up planning. Radiotherapy and chemotherapy should be considered in association with surgery in disseminated forms or after removal.

    Only a small number of patients with aggressive B-cell lymphoma take part in clinical trials, and elderly patients in particular are under-represented. Therefore, we studied data of the population-based nationwide Netherlands Cancer Registry to determine trends in incidence, treatment and survival in an unselected patient population. We included all patients aged 15 years and older with newly diagnosed diffuse large B-cell lymphoma or Burkitt lymphoma in the period 1989–2010 and mantle cell lymphoma in the period 2001–2010, with follow up until February 2013. We examined incidence, first-line treatment and survival. We calculated annual percentage of change in incidence and carried out relative survival analyses. Incidence remained stable for diffuse large B-cell lymphoma (n=23,527), while for mantle cell lymphoma (n=1,634) and Burkitt lymphoma (n=724) incidence increased for men and remained stable for women. No increase in survival for patients with aggressive B-cell lymphoma was observed during the period 1989–1993 and the period 1994–1998 [5-year relative survival 42% (95%CI: 39%–45%) and 41% (38%–44%), respectively], but increased to 46% (43%–48%) in the period 1999–2004 and to 58% (56%–61%) in the period 2005–2010. The increase in survival was most prominent in patients under 65 years of age, while there was a smaller increase in patients over 75 years of age. However, when untreated patients were excluded, patients over 75 years of age had a similar increase in survival to younger patients. In the Netherlands, survival for patients with aggressive B-cell lymphoma increased over time, particularly in younger patients, but also in elderly patients when treatment had been initiated. The improvement in survival coincided with the introduction of rituximab therapy and stem cell transplantation into clinical practice. PMID:25512643

    Full Text Available The WHO classification of lymphomas allows for a group of diseases that have features intermediate between those of Burkitt lymphoma and diffuse large B-cell lymphoma. These are a diverse group of diseases whose genetics and clinical course are yet to be fully described. We report an unusual case of high grade B-cell lymphoma, intermediate between DLBCL and BL, lacking CD10 expression in which the chromosomal translocation t(3;8(q27;q24 was found to be the sole chromosomal abnormality. FISH analysis demonstrated juxtaposition of the BCL6 and MYC loci without obvious involvement of the IGH locus, suggesting constitutive MYC expression due to promoter substitution. The patient responded to intensive chemotherapy and remains in remission two years after finishing therapy.

    Full Text Available While the defects in HLA class I-mediated Ag presentation by Burkitt lymphoma (BL have been well documented, CD4+ T-cells are also poorly stimulated by HLA class II Ag presentation, and the reasons underlying this defect(s have not yet been fully resolved. Here, we show that BL cells are deficient in their ability to optimally stimulate CD4+ T cells via the HLA class II pathway. The observed defect was not associated with low levels of BL-expressed costimulatory molecules, as addition of external co-stimulation failed to result in BL-mediated CD4+ T-cell activation. We further demonstrate that BL cells express the components of the class II pathway, and the defect was not caused by faulty Ag/class II interaction, because antigenic peptides bound with measurable affinity to BL-associated class II molecules. Treatment of BL with broystatin-1, a potent modulator of protein kinase C, led to significant improvement of functional class II Ag presentation in BL. The restoration of immune recognition appeared to be linked with an increased expression of a 17 kDa peptidylprolyl-like protein. These results demonstrate the presence of a specific defect in HLA class II-mediated Ag presentation in BL and reveal that treatment with bryostatin-1 could lead to enhanced immunogenicity.

Denis received his BA in 1933 and graduated as a physician in 1935 from Trinity College, Dublin. After serving as a surgeon in the Royal Army Medicine Corps during World War II, he worked as a surgeon and lecturer in Africa. It was in Africa that he developed exceptional observational and analytical skills, which led him to identify and formally develop a successful treatment for a childhood cancer that is now called Burkitt Lymphoma. The influence of Christianity in his life was huge. Throughout his life he remained extremely modest, attributing much of what he had achieved to the work of others. Denis's contributions to haemato-oncology remain salient today, and his discoveries continue to generate new research. Throughout his career he received some of the highest scientific honours from many different countries across the globe. © 2012 Blackwell Publishing Ltd.

    This case report explores the potential role of FDG PET/CT in HIV -associated systemic non-Hodgkin's lymphoma (HIV-NHLs). In our locality, there are a cumulative total of 5523 reported HIV infections cases since 1984. We reported a case of HIV-related Burkitt's lymphoma (BL) and a case of diffuse large B-cell lymphoma (DLBCL) that underwent PET/CT examination in our PET centre. In HIV-NHLs patients, we must be reminded that not all hypermetabolic foci represent lymphomatous lesions. There is a close correlation between the pattern of lymphoid tissue activation in FDG PET/CT and HIV progression in patients without HIV-related malignancy. The unique patterns of lymphoid tissue activation observed in HIV-infected patients have great clinical implications. Secondly, HIV-infected patients are prone to suffer from opportunistic infections due to immunosuppression, particularly in those with high levels of HIV viral loads. FDG PET/CT cannot reliably differentiate metabolic active lymphoma from other benign diseases such as inflammation in the context of low CD4 count and high viral loads. In those cases, benign markedly hypermetabolic foci can be erroneously interpreted as lymphoma, particularly in those normal-sized lymph nodes. Furthermore, FDG PET/CT may be useful for assessing the efficacy of HAART in suppressing HIV replication and detecting its complication such as lipodystrophy. FDG PET/CT may play a potential useful role in staging and management of HIV -associated systemic non-Hodgkin's lymphoma. Plasma variables such as viral loads and CD4 count must be taken into account during image interpretation. FDG PET/CT as a potential useful tool for diagnosis, treatment response assessment and disease relapse detection in HIV -associated systemic non-Hodgkin's lymphoma worth to be further explored

    This study was designed to assess the influence of highly active antiretroviral therapy (HAART) on non-Hodgkin lymphoma (NHL) among patients infected with human immunodeficiency virus (HIV). Within EuroSIDA, a multicenter observational cohort of more than 8500 patients from across Europe......, the incidences of NHL and subtypes (Burkitt, immunoblastic, primary brain lymphoma [PBL], and other/unknown histology) were determined according to calendar time of follow-up, and for those who initiated HAART (> or =3 drugs) also time on HAART. Potential predictive factors of NHL were evaluated in Cox...

    Plasmablastic lymphoma (PBL) is an aggressive lymphoma, often arising in the context of immunodeficiency and associated with Epstein-Barr virus (EBV) infection. The most frequently detected genetic alteration is the deregulation of MYC gene through the translocation - t(8;14)(q24;q32). The diagnosis of PBL is often challenging because it has an overlap in morphology, immunophenotype, cytogenetics and virus association with other lymphomas and plasma cell neoplasms; further, its molecular basis remains elusive. In the present study we aimed to better define the possible contribution of EBV infection as well as miRNA deregulation in PBL pathogenesis. We studied 23 cases of PBL, 19 Burkitt lymphomas (BL), and 17 extra-medullary plasmacytoma (EMPC). We used qPCR and immunohistochemistry to assess EBV latency patterns, while micro-RNA (miRNA) profiling was performed by next generation sequencing (Illumina) and validated by qPCR. Our analysis revealed a non-canonical EBV latency program with the partial expression of some proteins characterizing latency II and the activation of an abortive lytic cycle. Moreover, we identified miRNA signatures discriminating PBL from BL and EMPC. Interestingly, based on the miRNA profile, PBL appeared constituted by two discrete subgroups more similar to either BL or EMPC, respectively. This pattern was confirmed in an independent set of cases studied by qPCR and corresponded to different clinico-pathological features in the two groups, including HIV infection, MYC rearrangement and disease localization. In conclusion, we uncovered for the first time 1) an atypical EBV latency program in PBL; 2) a miRNA signature distinguishing PBL from the closest malignant counterparts; 3) the molecular basis of PBL heterogeneity.

De acordo com a classificação atual, os tipos histológicos foram: linfoma linfoblástico de células B precursoras (2, linfoma cutâneo de grandes células anaplásico (1, linfoma de células B periféricas, sugestivo de Burkitt (1, e linfoma linfoblástico de células T precursoras (1. Todos os pacientes foram submetidos a quimioterapia, sendo que dois estão em remissão clínica, dois morreram e um continua em tratamento. Após a introdução da terapia anti-retroviral combinada e o aumento dos transplantes de órgãos sólidos ocorre maior risco de neoplasia nesses pacientes. Desse modo, é importante o seguimento desses pacientes para determinar os fatores de risco para o desenvolvimento de neoplasias e definir adequada estratégia de tratamento.The outcomes of five children with non-Hodgkin's lymphomas associated with immunodeficiency or immunosuppression is reported: three children with HIV, one with primary immunodeficiency and one after liver transplantation. According to the REAL classification, two patients had precursor B-lymphoblastic lymphomas, one had an anaplastic large cell lymphoma, one had a peripheral B-cell neoplasm suggestive of Burkitt's lymphoma, and one had precursor T-lymphoblastic lymphoma. All patients received chemotherapy. Two are in complete remission, two died and one remains under treatment. There has been an increasing awareness of the risk of non-Hodgkin's lymphoma and lymphoproliferative disorders after active antiretroviral therapy and with the expansion of solid organ transplant programs in the pediatric setting. Thus, for these patients it is important to establish risk factors for hematological disorders and determine the optimal and safest

    Full Text Available Abstract Background The Epstein-Barr virus (EBV is associated with lymphoid malignancies, including Burkitt's lymphoma (BL, and can transform human B cells in vitro. EBV-harboring cell lines are widely used to investigate lymphocyte transformation and oncogenesis. Qualitative EBV gene expression has been extensively described, but knowledge of quantitative transcription is lacking. We hypothesized that transcription levels of EBNA1, the gene essential for EBV persistence within an infected cell, are similar in BL cell lines. Results To compare quantitative gene transcription in the BL cell lines Namalwa, Raji, Akata, Jijoye, and P3HR1, we developed an oligonucleotide microarray chip, including 17 housekeeping genes, six latent EBV genes (EBNA1, EBNA2, EBNA3A, EBNA3C, LMP1, LMP2, and four lytic EBV genes (BZLF1, BXLF2, BKRF2, BZLF2, and used the cell line B95.8 as a reference for EBV gene transcription. Quantitative polymerase chain reaction assays were used to validate microarray results. We found that transcription levels of housekeeping genes differed considerably among BL cell lines. Using a selection of housekeeping genes with similar quantitative transcription in the tested cell lines to normalize EBV gene transcription data, we showed that transcription levels of EBNA1 were quite similar in very different BL cell lines, in contrast to transcription levels of other EBV genes. As demonstrated with Akata cells, the chip allowed us to accurately measure EBV gene transcription changes triggered by treatment interventions. Conclusion Our results suggest uniform EBNA1 transcription levels in BL and that microarray profiling can reveal novel insights on quantitative EBV gene transcription and its impact on lymphocyte biology.

    Full Text Available Breast involvement by lymphoma is uncommon and poses challenges in diagnosis. Breast involvement by malignant lymphoma, whether primary or secondary, is a rare event. Primary breast lymphomas account for 0.38% - 0.7% of all non-Hodgkin lymphomas, 1.7%-2.2% of all extranodal non-Hodgkin lymphomas, and only 0.04% - 0.5% of all breast cancer cases. Most frequent primary breast lymphomas are diffuse large B cell lymphomas (53%. Breast mucosa-associated lymphoid tissue (MALT lymphomas account for a small fraction of all the MALT lymphomas (1% - 2%. Herein we report a case of a patient with primary breast MALT lymphoma and its presentation on different imaging modalities. Two years after the presentation and treatment with eight cycles of chemotherapy, the patient is alive and well, without evidence of residual disease or recurrence.

    Lymphomas are the third malignancy in children, and within them non-Hodgkin lymphoma (NHL) accounts for just 7% of cancers in children under 15 years old. Chemotherapy is currently the treatment of choice. The objective of this study is to analyze the toxicity caused by the treatment in pediatric patients diagnosed with NHL. A retrospective study was conducted on patients diagnosed with mature B-cell NHL, treated according to the LMB protocol 2001, from January 2007 to February 2014. Data concerning the diagnosis, treatment and toxicities that developed in the patients during the same period were collected. A total of 20 mature B-cell NHL cases were diagnosed: 16 Burkitt lymphomas, 2 diffuse large cell lymphomas and 2 mature leukemias. Almost two-thirds (65%) of patients were classified in a high grade stage (iii-iv) at diagnosis. Serious infectious processes, severe myelosuppression, liver abnormalities, and mucositis were the most frequent toxicities. Overall survival was 95% (19/20). One patient died of causes unrelated to the illness. Despite the excellent survival rate, most patients diagnosed with NHL mature B cells experience grade iii and iv toxicities during treatment.

    Full Text Available Introduction: The primary nasal lymphoma is an uncommon extranodal tumor and represents 0.44% of all Extranodal lymphomas in this region. The primary nasal lymphoma derives from the T-lineage in nearly 75% of the cases. Objective: To describe a case of nasosinusal lymphoma of T Natural Killer cells, attended in the Clinical Hospital of the Federal University of Goiás. Case Report: 48-year-old female patient with diffuse tumefaction in the left hemiface of firm-elastic consistency and painful upon digital compression. Face sinuses tomography identified a total maxillary veiling to the left and some posterior ethmoidal cells. With the diagnostic hypothesis of a tumor affection, we opted for the surgical removal via a transmaxillary approach and the material was sent for biopsy. The histopathological exam diagnosed a highly necrotic tumor of angiocentric pattern, polymorphic and atypical lymphoid population (T /NK Lymphoma; with the prognosis, the patient was submitted to chemical therapy with total regression of the facial edema. Final Comments: The otorhinolaryngologist must be attentive as regards the existence of lymphomas among the nasosinusal diseases, because the early diagnosis improves the survival as it prevents metastases, growth and local destruction.

    Highlights: •Mouse model of human Burkitt lymphoma revealed cancer inhibition by PL. •Treatment with PL led to apoptosis of malignant but not normal B cells. •PL inhibited LMP1–NF-κB–Myc-dependent target genes including p21-encoding Cdkn1a. •PL holds promise for new interventions approaches to hematologic malignancies. -- Abstract: Piperlongumine (PL), isolated from the fruit of Long pepper, Piper longum, is a cancer-inhibiting compound that selectively kills tumor cells while sparing their normal counterparts. Here we evaluated the efficacy with which PL suppresses malignant B cells derived from a newly developed, double-transgenic mouse model of human endemic Burkitt lymphoma (BL), designated mCD40-LMP1/iMyc Eμ . PL inhibited tumor cell proliferation in a concentration-dependent manner and induced apoptosis of neoplastic but not normal B cells. Treatment with PL resulted in downregulation of EBV-encoded LMP1, cellular Myc, constitutive NF-κB activity, and a host of LMP1-Myc-NF-κB-regulated target genes including Aurka, Bcat1, Bub1b, Ccnb1, Chek1, Fancd2, Tfrc and Xrcc6. Of note, p21 Cip1 -encoding Cdkn1a was suppressed independent of changes in Trp53 mRNA levels and p53 DNA-binding activity. Considering the central role of the LMP1–NF-κB–Myc axis in B-lineage neoplasia, these findings further our understanding of the mechanisms by which PL inhibits B-lymphoma and provide a preclinical rationale for the inclusion of PL in new interventions in blood cancers

    Full Text Available Abstract A family is reported in which three male siblings of Asian descent developed non-Hodgkin's lymphoma (NHL. Case 1 was diagnosed with indolent follicular lymphoma stage IIIA at age 45. Case 2 presented with large B-cell lymphoma stage IIB at age 56. Chromosomal investigation of the peripheral blood did not show abnormalities. Chemotherapy induced a complete remission. However, after a period of nearly ten years he developed acute myeloid leukaemia. Case 3 developed large B-cell lymphoma stage IVA at age 52. Cytogenetic analysis in peripheral blood was normal. Shared genetic and environmental risk factors remain to be identified in this family. Familial aggregation of NHL is uncommon. In some families, various forms of immunodeficiency have been found. In addition to coincidental clustering of cases, and rare cases explained by known tumour syndromes such as Li-Fraumeni (like syndrome, other familial cases may share as yet unknown genetic and/or environmental risk factors.

    Background: Extracellular circulating DNA (cfDNA) can be found in small amounts in plasma of healthy individuals. Increased levels of cfDNA have been reported in patients with cancer of breast, cervix, colon, liver and it was shown that cfDNA can originate from both tumour and non-tumour cells. Objectives: Levels of cfDNA of a large series of children with lymphoma were evaluated and analyzed in relation with clinical characteristics. Methods: plasma cfDNA levels obtained at diagnosis in 201 paediatric lymphoma patients [43 Hodgkin lymphomas (HL), 45 anaplastic large cell lymphomas (ALCL), 88 Burkitt lymphomas (BL), 17 lymphoblastic (LBL), 8 diffuse large B cell lymphoma (DLBCL)] and 15 healthy individuals were determined using a quantitative PCR assay for POLR2 gene and, in addition, for NPM-ALK fusion gene in ALCL patients. Wilcoxon rank sum test was used to compare plasma levels among different patient subgroups and controls and to analyze relationship between levels of cfDNA and clinical characteristics. Results: Levels of cfDNA in lymphoma patients were significantly higher compared with controls (p<0.0001). CfDNA was associated with median age (p=0.01) in HL, and with stage in ALCL (p=0.01). In HL patients high cfDNA levels were correlated with poor prognosis (p=0.03). In ALCL we found that most of the cfDNA (77%) was non-tumor DNA. Conclusion: level of plasma cfDNA might constitute an important non-invasive tool at diagnosis in lymphoma patients' management; in particular in patients with HL, cfDNA seems to be a promising prognostic biomarker.

    It has been recognized that cure is possible for human immunodeficiency virus (HIV)-infected patients with Burkitt lymphoma/leukemia (BL) if appropriate chemotherapy is used. The introduction of rituximab in BL therapeutic schemes has been scarcely explored. The outcome and toxicity of HIV-positive patients with BL treated in a rituximab and intensive chemotherapy-based trial was evaluated. Thirty-six consecutive patients, 15 to 55 years of age, diagnosed with advanced stage BL were recruited from July 2003 to August 2006, stratified according to HIV infection status and treated with 6 cycles of intensive chemotherapy including 8 doses of rituximab. Nineteen of the patients (53%) were HIV-infected. Their clinical characteristics were comparable to those of the HIV-negative patients. Complete remission (CR) rates were 88% and 84%, respectively, for HIV-negative and -positive patients. Twenty-seven patients (82% and 68%, respectively, for HIV-negative and -positive patients) completed the 6 protocol scheduled cycles. HIV-infected patients presented higher incidences of grade 3-4 mucositis (27% vs 7% of cycles, P = .0005) and severe infectious episodes (26% vs 8%, P = .0025). However, there were no statistically significant differences in 2-year overall survival (82%, 95% confidence interval [CI], 65%-99% and 73%, 95% CI, 54%-92%, respectively) or 2-year disease-free survival (93%, 95% CI, 82%-99% and 87%, 95% CI 72%-99%, respectively). Intensive immunochemotherapy can be administered safely to patients with HIV infection. Despite a higher incidence of severe mucositis and infections the remission and survival rates are comparable to those observed in HIV-negative patients. (Copyright) 2008 American Cancer Society.

    Latent EBV infection is associated with several malignancies, including EBV post-transplant lymphoproliferative disorders (LPD, Hodgkin and non-Hodgkin lymphomas, nasopharyngeal carcinoma and Burkitt lymphoma. The range of expression of latent EBV antigens varies in these tumors, which influences how susceptible the tumors are to immunotherapeutic approaches. Tumors expressing type III latency, such as in LPD, express the widest array of EBV antigens making them the most susceptible to immunotherapy. Treatment strategies for EBV-related tumors include restoring normal cellular immunity by adoptive immunotherapy with EBV-specific T cells and targeting the malignant B cells with monoclonal antibodies. We review the current immunotherapies and future studies aimed at targeting EBV antigen expression in these tumors.

    The aim of this investigation was to report incidence of childhood leukemia, lymphoma and thyroid neoplasms in children under 15 years of age living in the vicinity of the French Marcoule nuclear reprocessing plant. This exhaustive and retrospective survey was carried out between 1985 and 1995 in children aged under 14 at the time of diagnosis and living inside a 35 kilometer zone around the nuclear site. 656 practitioners, 109 medical analysis laboratories and 5 hospitals or cancer institutes were investigated. A panel of experts checked each case. 48 cases of acute leukemia (39 acute lymphoid leukemia and 9 acute myeloid leukemia), 15 cases of lymphoma (8 Hodgkin lymphomas - 53 % - and 7 non hodgkinian lymphomas including 5 Burkitt lymphomas), 1 case of chronic myeloid leukemia and 1 case of papillary thyroid cancer, appeared among the 1,116,442 children-years followed. The total incidences of leukemias and lymphomas were respectively 4.12 and 1.29.10 -5 . Standardised Incidence Ratios, calculated according to Poisson methods and Bayesian inference, with various reference rates did not show any excess of risk: 100.67 (95 % confidence interval 72-131) for leukemia. Children under 5 years old and living in non exposed areas to dominant winds or downstream Rhodanian water drawing presented a 3 or 4 fold decreased risk of leukemia than others (the latter still having an identical risk to that of the general population). This was not true for lymphomas, nor for the other age groups. Over the entire zone, children do not have an increased risk of malignant hematology disease but health monitoring by a systematic collection of cases remains useful around Marcoule. The assumption of aquiferous or air contamination thus still remains questionable: further studies investigating models of contamination are needed to take into account all other nonionizing leukemogenic factors (benzene and viral infection in particular) or correlation studies between health indicators and

    Primary breast lymphoma (PBL) is a rare entity accounting for less than 1% of all breast malignancies. Diagnostic criteria for primary Hodgkin's lymphoma of the breast are: the presence of sufficient tissue for diagnosis, close interaction between mammary tissue and lymphomatous infiltrate and no evidence or prior diagnosis of widespread lymphoma. Our case illustrates an unusual presentation of Hodgkin's lymphoma of the breast: clinically as inflammatory breast cancer and core biopsy as granulomatous mastitis, the final diagnosis requiring surgical biopsy. Current information regarding this entity is scant, mainly build upon its rarity. In this paper we assess the clinical presentation, the step-by-step diagnosis, the treatment and the importance of immunohistochemistry in this uncommon condition.

  20. Epidemiology of Epstein-Barr virus-associated pediatric lymphomas from Argentina.

    Science.gov (United States)

    Chabay, Paola; Preciado, María Victoria

    More than 90% of the population is infected by Epstein-Barr virus (EBV), which has sophisticatedly evolved to survive silently in B cells for the life of infected individuals. However, if the virus-host balance is disturbed, latent EBV infection could be associated with several lymphomas. The age at primary infection varies substantially worldwide, and exposure to EBV is likely to be due to socioeconomic factors. In Argentina, EBV infection is mostly subclinical and 90% of patients are seropositive by the age of 3 years; therefore, its epidemiological characteristics resemble those of an underdeveloped or developing population. EBV-positive Hodgkin lymphoma (HL) in young adults from developed populations has been attributed to delayed primary EBV infection as suggested by the association with recent mononucleosis development. EBV-associated Burkitt lymphoma and Hodgkin lymphoma in children from Argentina display frequencies similar to those observed in developed countries, whereas EBV presence in pediatric diffuse large B-cell lymphoma is slightly increased compared to those populations. However, EBV presence is statistically associated particularly with patients < 10 years of age in all three entities. Therefore, a relationship between low age of EBV seroconversion and B-cell lymphoma development risk could be suggested in children from Argentina.

    Full Text Available Mycosis fungoides is a cutaneous T-cell lymphoma with a high risk for developing secondary malignancies, especially B-cell lymphoproliferative disorders. About 40 cases of Hodgkin's lymphoma associated with mycosis fungoides have been reported in literature till date. We report a case of a 35-year-old gentleman who presented with intensely itchy reddish lesions all over the body. Multiple skin biopsies taken from the lesions on scalp and back confirmed the clinical diagnosis of mycosis fungoides. While on treatment, he presented with multiple bilateral cervical, axillary and inguinal lymphadenopathy 9 years after the primary diagnosis of mycosis fungoides. Excision biopsy of a cervical lymph node revealed partial effacement of architecture by a tumor comprising polymorphous background. Histopathology and immunohistochemistry revealed a diagnosis of Hodgkin's lymphoma - nodular sclerosis subtype. The patient was started on chemotherapy for stage IV Hodgkin's lymphoma. Our case emphasizes the importance of keeping secondary Hodgkin's lymphoma in mind while dealing with a patient of mycosis fungoides. Our case immunohistochemically supports the distinct etiopathogenesis of Epstein–Barr virus-negative Hodgkin's lymphoma vis-à-vis cutaneous mycosis fungoides.

    Full Text Available The results of two consecutive multicenter clinical trials enrolled 241 patient with childhood mature B-cells non-Hodgkin lymphomas/leukemia are presented. Patients received treatment according B-NHL 2004mab protocol (n = 83 and B-NHL 2010M (n = 158 with combined immunochemotherapy (ICT in Russian and Belarus pediatric clinics from 2004 to 2015 years. Primary patients with different mature B-NHL (Burkitt lymphoma/leukemia, diffuse large B-cell lymphoma and primary mediastinal B-cell lymphoma (DLBCL and PMBCL aged from 2 to 18 years are included in the studies.Protocol B-NHL 2004mab for treatment of children and adolescents with B-NHL/B-AL, stage III and IV, includes a combination of chemotherapy (PCT and rituximab – an antibody against the B-cells receptor CD20. PCT courses similar to those in the B-NHL BFM90 protocol (group III with the exception of methotrexate dose in induction courses, reduced to 1 g/m2 /24 h in order to reduce toxicity. Rituximab (Mabthera, 375 mg/m2 /h used for the first time in the treatment of children and adolescents with B-NHL. Of the 83 patients included, clinical remission was achieved in 77 (92.8 %. With a median follow time of 51.6 months, remission continued in 23 (85.2 % patients with B-AL, in 32 (88.9 % patients with LB and 19 (95.0 % patients – with DLBCL. With median follow time of 65.2 months, event-free and overall survival was 84 ± 6 and 82 ± 8 %, respectively.Based on previous experience in order to further optimize B-NHL treatment, new protocol B-NHL 2010M with effect-adapted therapy and improvement of stratification risk group criteria was proposed. Overall survival in patients of 1st and 2nd risk groups with full implementation of diagnosis and treatment is approaching 100 %. In interim analysis of 3rd risk group patients, pOS was 88 ± 3 %.

    Gastric non-Hodgkin lymphoma is a rare tumour that represents approximately 7% of all stomach cancers and 2% of all lymphomas. The most frequent location of gastric MALT (mucosa associated lymphoid tissue) lymphomas is in the antrum in 41% of the cases, and 33% can be multifocal. The risk of spontaneous perforation of a gastric MALT lymphoma is 4-10%. 24 year old male patient carrying the Human Immunodeficiency Virus, who began with signs and symptoms of acute abdomen and fever 72 hours before arriving in the emergency room. A computed tomography was performed that showed free fluid in the cavity, and gastric wall thickening. The patient underwent a laparotomy, finding absence of the anterior wall of the stomach, sealed with the left lobe of the liver, colon and omentum. Total gastrectomy, with oesophagosty and jejunostomy tube, was performed. Gastric perforation secondary to a MALT lymphoma is rare, with high mortality. There is limited information reported of this complication and should be highly suspected in order to provide appropriate treatment for a complication of this type.

    Full Text Available Primary bone lymphoma (PBL is an uncommon tumor accounting for approximately 4-5% of extra nodal lymphoma and less than 1% of all non-Hodgkin′s lymphoma. Disease may be complicated at presentation by pathological fracture or spinal cord compression. Diffuse large-B-cell lymphoma (DLBCL accounts for the majority of cases of PBL. Owing to its rarity, only a few retrospective studies have been published addressing the prognosis and treatment of primary bone lymphoma. In this paper, we report our experience with two cases of PBL treated with chemotherapy and radiotherapy and review literature to elucidate the optimal treatment of primary bone lymphoma.

    Purpose: We aimed to describe computed tomography (CT) findings in patients with peritoneal, omental and mesenteric lymphoma involvement. Materials and methods: We searched our archive retrospectively to find out patients with peritoneal, omental and mesenteric lymphoma involvement. We found 16 patients with non-hodgkin lymphoma meeting these criteria. CT studies of these patients were reevaluated for the presence of peritoneal involvement, ascites, omental mass, organomegaly, retroperitoneal lymphadenopathy, bowel wall thickening and other associated findings. Results: There were 14 males and 2 females with peritoneal and/or mesenteric and omental lymphoma involvement. Mean age was 39 (range 4-76). Subgroups of non-hodgkin lymphoma were diffuse large B-cell lymphoma (n = 11), small cell lymphocytic lymphoma (n = 2), small cleaved cell lymphoma (n = 1), T-cell lymphoma (n = 1) and Burkitt's lymphoma (n = 1). Peritoneal involvement was seen in 15 patients (93.8%) in the form of linear (n = 12) and nodular (n = 3) thickening. Ascites was seen in 12 (75%) patients. Omental and mesenteric masses were present in 10 (66.6%) and 10 (66.6%) patients, respectively. Bowel wall thickening, retroperitoneal lymphadenopathy and hepatosplenomegaly were also common and observed in 10, 10 and 11 patients, respectively. Solid organ involvement in the form of liver and splenic lesions was seen in 9 (56%) patients. Conclusion: Peritoneal involvement can be seen in many subtypes of lymphoma and most frequently in diffuse large B-cell lymphoma. Peritoneal lymphomatosis can mimic peritoneal carcinomatosis and should be included in the differential diagnosis list in patients with ascites, hepatosplenic lesions and unidentified cause of peritoneal thickening on CT in a male patient.

  7. Non-Hodgkin's lymphoma presenting as a primary bladder tumor: a case report

    Full Text Available Abstract Introduction Primary lymphoma of the bladder represents 0.2% of all bladder malignancies. Secondary involvement of the bladder by malignant lymphoma occurs in 10% to 50% of cases. Most lymphomas of the bladder are non-Hodgkin's lymphomas of the B-cell type, with preponderance among women. The impact of positron emission tomography (PET on tumor staging has recently become very important due to its use in the study of diagnosis extension and individual therapy design. Case presentation We report the case of a 79-year-old Caucasian man with intermittent haematuria as the presenting symptom of non-Hodgkin's lymphoma of the bladder. He was first diagnosed with primary lymphoma of the bladder using the current staging method, but a positron emission tomography study subsequently revealed that he instead had a secondary involvement of the bladder. Conclusion The staging of non-Hodgkin's lymphomas, which is useful in order to plan accurate therapy, has been changing since the introduction of positron emission tomography scanning. Primary lymphomas of the bladder, although very rare, may be even more uncommon when this imaging technique is used to assess the extension of the disease. Although the interpretation of this technique has some limitations that should be taken into account, the extensive use of positron emission tomography should nonetheless help improve the diagnosis of this disease.

    We report four cases of lingual tonsillar MALT (mucosal associated lymphoid tissue) lymphoma. The cases consisted of a 68-year-old woman, a 60-year-old woman, a 55-year-old woman, and a 75-year-old man. The clinical stages of these cases were IIA, IA, IV (invasion to bone marrow) and IA, respectively. As some types of lingual tonsillar MALT lymphomas show hypertrophy of the lymphoid tissue but not a mass, it is not easy to make a diagnosis of MALT lymphoma only by fiberscopic findings. Furthermore, the small size of biopsy specimens or tissue damaged by forceps can show a false negative consult. Repeat biopsies are sometimes required for a definitive diagnosis. It is important to take large biopsy specimens with little damage, and to discuss well with pathologists. (author)

    Primary effusion lymphoma-like lymphoma (PEL-LL) is a rare B-cell lymphoma that the etiology remains unclear. We describe a case of PEL-LL with a pleuropericardial effusion. Diagnosis required long period of time as it followed a unique progress of disappearance and recurrence of the body cavity effusion. We finally had a diagnosis of B-cell lymphoma by the immunocytochemistry of effusion using the cell block procedure. Authors consider that it is valuable to actively try the cell block procedure at the time of the first drainage for early diagnosis, if the body cavity effusion due to the malignancy is suspected.

    Infection with Epstein-Barr virus (EBV) early in life and repeated malaria exposure have been proposed as risk factors for endemic Burkitt lymphoma (eBL). Infants were enrolled from 2 rural sites in Kenya: the Kisumu District, where malaria transmission is holoendemic and risk for eBL is high, and the Nandi District, where malaria transmission is limited and the risk for eBL is low. Blood samples were taken from infants through 2 years of age to measure EBV viral load, EBV antibodies, and malaria parasitemia. We observed a significantly younger age at time of primary EBV infection in children from Kisumu compared with children from Nandi (mean age, 7.28 months [±0.33 SEM] in Kisumu vs 8.39 months [±0.26 SEM] in Nandi), with 35.3% of children in Kisumu infected before 6 months of age. To analyze how different predictors affected EBV viral load over time, we performed multilevel mixed modeling. This modeling revealed that residence in Kisumu and younger age at first EBV infection were significant predictors for having a higher EBV viral load throughout the period of observation. Children from a region at high risk for eBL were infected very early in life with EBV, resulting in higher viral loads throughout infancy.

    Full Text Available Abstract Background To describe a rare manifestation of mantle cell lymphoma (MCL in conjunctiva, with clinical, hisologic, immunohistologic and genetic findings together with review of the Literature. Case presentation Most ocular adnexal lymphomas are extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT. A few cases of ocular adnexal mantle cell lymphomas have been reported in the literature. We present a case of mantle cell lymphoma presenting as right conjunctival mass of at least three months duration in a 64-year-old man. Histopathologic examination showed a proliferation of monomorphous small-to-medium-sized lymphoid cells with cleaved nuclei in the subconjunctiva. By immunohistochemistry, the infiltrate was positive for CD20, CD5, BCL-2, cyclin D1, and the transcription factor SOX11. Fluorescent in situ hybridization demonstrated the presence of IGH-CCND1 fusion indicating t(11;14. Conclusion A rigorous approach to initial diagnosis and staging of small cell lymphomas of the ocular adnexa is needed. The recognition of ocular MCL requires appropriate immunohistochemical staining and/or genetic confirmation to differentiate this rare form of presentation of MCL from other more frequent small cell lymphomas.

    Full Text Available Abstract Introduction Breast involvement by non-Hodgkin lymphoma is particularly rare in men. We describe the case of a patient with a rapidly growing, painless gynecomastia-like nodule in the left breast. On ultrasonography, the nodule was suspicious for breast carcinoma. Case presentation A breast biopsy from a 54-year-old Caucasian man showed the morphoimmunophenotypical features of grade 3 follicular lymphoma. Moreover, fluorescence in situ hybridization analysis showed a t(14,18 translocation suggesting breast involvement by a systemic lymphoma rather than a primary breast lymphoma. The histological diagnosis was subsequently confirmed after nodule excision. Mediastinal and abdominal node involvement was then identified on computed tomography and positron emission tomography scans during staging examinations. Our patient was treated with chemotherapy. After three years our patient experienced a right retro-areolar relapse. He then received two further cycles of chemotherapy but developed a myeloid acute leukemia and, as a result of this, he subsequently died. Conclusions The rarity of breast lymphomas, especially in men, and the problems related to the therapeutic choices with these tumors require molecular techniques in association with classical histological diagnosis.

  15. iNKT cells suppress the CD8+ T cell response to a murine Burkitt's-like B cell lymphoma.

    Directory of Open Access Journals (Sweden)

    Ryan L Bjordahl

    Full Text Available The T cell response to B cell lymphomas differs from the majority of solid tumors in that the malignant cells themselves are derived from B lymphocytes, key players in immune response. B cell lymphomas are therefore well situated to manipulate their surrounding microenvironment to enhance tumor growth and minimize anti-tumor T cell responses. We analyzed the effect of T cells on the growth of a transplantable B cell lymphoma and found that iNKT cells suppressed the anti-tumor CD8(+ T cell response. Lymphoma cells transplanted into syngeneic wild type (WT mice or Jalpha18(-/- mice that specifically lack iNKT cells grew initially at the same rate, but only the mice lacking iNKT cells were able to reject the lymphoma. This effect was due to the enhanced activity of tumor-specific CD8(+ T cells in the absence of iNKT cells, and could be partially reversed by reconstitution of iNKT cells in Jalpha 18(-/- mice. Treatment of tumor-bearing WT mice with alpha -galactosyl ceramide, an activating ligand for iNKT cells, reduced the number of tumor-specific CD8(+ T cells. In contrast, lymphoma growth in CD1d1(-/- mice that lack both iNKT and type II NKT cells was similar to that in WT mice, suggesting that type II NKT cells are required for full activation of the anti-tumor immune response. This study reveals a tumor-promoting role for iNKT cells and suggests their capacity to inhibit the CD8(+ T cell response to B cell lymphoma by opposing the effects of type II NKT cells.

    Background: We present a case of primary renal lymphoma no bilateral Hodgkin of both kidneys which is uncommon Objective: To present the clinical case of a patient that dies four days of their entrance in which was discovered a bilateral renal mass with the anatomopathological diagnostic of primary renal lymphoma for necropsy stud . Case presentation: It is a 40 year-old patient, with family antecedents of neoplasias and personal of gastritis of seven months of evolution. The patient was entered for fever of 39 ℃ an important abdominal pain, in which was important the anemic and constitutional syndrome with loss of 11 kg in the last months; and diminished diuresis. A tumor was verified between 12 and 15 cm in both flanks of hard and not painful irregular surface. The patient presented unfavorable evolution for what was moved to room of cares intermissions. In the analytic study they were verified as exams of importance the Hb 89 g/L, the speed of globular sedimentation of 95 mm/first hour, the LDH 1495 UI/L, the creatinine of 537 mmol /L and several pathological glycemias one of them of 20 mmol/L. The x- ray results as much the ultrasonography as the contrasted on-line axial tomography guided the possibility to be a renal tumor. The medullogram and the laparoscopic were not useful for the diagnosis. The patient died and she was carried out histopathological necropsy study, which informed a lymphoma not bilateral Hodgkin of kidney of cells B, without an affectation to another organ Conclusions: They are uncommon the cases of primary renal lymphoma, since the renal affectation for a process lymphproliferative is in general secondary to a systemic illness. This case completes the fundamental approaches of Malbrain to consider it as a lymphoma non Hodgkin. The diagnosis is carried out by means of renal biopsy, during the surgery or necropsy for anatomopathological study. (author)

    There have been 23 reports of primary central nervous system anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma in the literature. Here we report the 24th case of a 40-year-old man who presented with occipital headache for one month. His contrast-enhanced brain MRI showed enhancement around the right temporal lobe, which suggested a diagnosis of hypertrophic pachymeningitis. He improved with steroid therapy. After discharge, however, he was readmitted with generalized convulsive seizures. Finally, he was diagnosed as primary central nervous system ALK-positive anaplastic large cell lymphoma by brain biopsy. Primary central nervous system lymphoma invading dura matter can rarely manifests as a unilateral pachymeningitis. Therefore, in case of pachymeningitis, we should pay attention to the possibility of infiltration of lymophoma with meticulous clinical follow-up.

    Three cases of lung carcinomas with unusual histologic appearances that have received little or no comment in the literature are presented. They were initially confused with malignant lymphoma because of a diffuse proliferation of relatively monotonous cells simulating large-cell immunoblastic lymphoma. In each case, the possibility of malignant lymphoma was excluded with confidence after the immunohistochemical study (leucocyte common antigen negative and cytokeratins positive), although with conventional microscopy several foci of cohesive groups of tumor cells were observed. The tumors were ranked at the clinical stage II or III when they were initially discovered, but all patients died of disease within 1 year. The present three tumors show an aggressive behavior and could be classified into a peculiar variant of 'large cell' carcinoma. It is necessary for surgical pathologists to have an idea of these variants of lung carcinoma in order to avoid erroneous diagnosis.

    Full Text Available Tumor metabolism has been the object of several studies in the past, leading to the pivotal observation of a consistent shift toward aerobic glycolysis (so-called Warburg effect. More recently, several additional investigations proved that tumor metabolism is profoundly affected during tumorigenesis, including glucose, lipid and amino-acid metabolism. It is noticeable that metabolic reprogramming can represent a suitable therapeutic target in many cancer types. Epstein–Barr virus (EBV was the first virus linked with cancer in humans when Burkitt lymphoma (BL was described. Besides other well-known effects, it was recently demonstrated that EBV can induce significant modification in cell metabolism, which may lead or contribute to neoplastic transformation of human cells. Similarly, virus-induced tumorigenesis is characterized by relevant metabolic abnormalities directly induced by the oncoviruses. In this article, the authors critically review the most recent literature concerning EBV-induced metabolism alterations in lymphomas.

    Targeting signaling pathways is an attractive approach in many malignancies. The PI3K/Akt/mTOR pathway is activated in a number of human neoplasms, accompanied by lower overall and/or disease free survival. mTOR kinase inhibitors have been introduced in the therapy of renal cell carcinoma and mantle cell lymphoma, and several trials are currently underway. However, the pathological characterization of mTOR activity in lymphomas is still incomplete. mTOR activity and the elements of mTOR complexes were investigated by immunohistochemistry on tissue microarrays representing different human non-Hodgkin-lymphomas (81 cases) and Hodgkin-lymphomas (87 cases). The expression of phospho-mTOR, phospho-4EBP1, phospho-p70S6K, phospho-S6, Rictor, Raptor and Bcl-2, Bcl-xL, Survivin and NF-kappaB-p50 were evaluated, and mTOR activity was statistically analyzed along with 5-year survival data. The in vitro and in vivo effect of the mTOR inhibitor rapamycin was also examined in human Hodgkin-lymphoma cell lines. The majority (>50%) of mantle cell lymphoma, Burkitt lymphoma, diffuse large B-cell lymphoma, anaplastic large-cell lymphoma and Hodgkin-lymphoma cases showed higher mTOR activity compared to normal lymphoid tissues. Hodgkin-lymphoma was characterized by high mTOR activity in 93% of the cases, and Bcl-xL and NF-kappaB expression correlated with this mTOR activity. High mTOR activity was observed in the case of both favorable and unfavorable clinical response. Low mTOR activity was accompanied by complete remission and at least 5-year disease free survival in Hodgkin-lymphoma patients. However, statistical analysis did not identify correlation beetween mTOR activity and different clinical data of HL patients, such as survival. We also found that Rictor (mTORC2) was not overexpressed in Hodgkin-lymphoma biopsies and cell lines. Rapamycin inhibited proliferation and induced apoptosis in Hodgkin-lymphoma cells both in vitro and in vivo, moreover, it increased the apoptotic

    -NOS (10%), diffuse large B-cell (8%), mantle cell (2%), B-SLL/CLL(2%), and Burkitt's (1%). In contrast, follicle center lymphoma (38%) was the most frequent histology among 32 patients with a prior history of lymphoma (secondary cases), whereas MALT lymphoma occurred in 19%, mantle cell 16%, low grade-NOS 9%, B-SLL/CLL 6%, diffuse large B-cell 6%, splenic marginal zone lymphoma 3%, and high grade-NOS 3%. The differences in frequencies of MALT lymphoma and follicle center lymphoma between the primary cases and secondary cases were highly significant (MALT p=0.002, FCL p=0.05). Of the primary cases, 60% were stage I, 11% II, 1% III, and 28% IV. Among 38 cases of primary MALT lymphoma, 74% were stage I, 13% stage II (bilateral disease), and 13% stage IV. Among primary follicle center lymphoma cases, 40% were stage I, 13% II, 7% III, and 40% IV. Thus MALT lymphoma had a preponderance of early stage presentation, compared with follicle center lymphoma (p=0.03). As determined by physical examination and CT scan, the lymphoma involved intraorbital soft tissue in 71% of cases, conjunctiva in 40%, lacrimal gland in 21%, extraocular muscle in 6%, and lacrimal sac in 5%. Synchronous bilateral orbital disease was seen in 13% of patients at presentation. Therefore a CT scan of both orbits is an important part of the initial work-up. Thirty-four patients received radiation to 41 orbits and were followed for a mean of 4.8 years. Twenty-four orbits were treated with photons and 17 with electrons. The 6-year actuarial local control rate was 100%. For 25 patients who had primary disease localized to one or both orbit(s), the 6-year actuarial distant relapse-free and overall survival rates were 77% and 89% respectively. Only 2 of 13 patients with localized MALT lymphoma treated with radiation relapsed in distant sites, both within 1 year. In contrast, 2 of 5 patients with follicle center lymphoma relapsed distantly (p=non significant). Conclusions: In this series, MALT lymphoma was the most

    Hydroa vacciniforme (HV)-like lymphoma is a rare, usually fatal Epstein-Barr virus-driven lymphoproliferative disease affecting children from Asia, Mexico, and South America. Cutaneous manifestations imitate HV, a benign photodermatosis in which systemic symptoms are not observed, and spontaneous regression occurs later in adolescence or young adulthood. We report a case of HV-like lymphoma in a 12-year-old girl, descendent from an ancient Amazon indigenous tribe that, as far as we know, represents the second Brazilian case ever reported in the medical literature.

    Full Text Available Individuals infected by HIV are at an increased risk for developing non-Hodgkin's lymphomas (AIDS-NHL. In the highly active antiretroviral therapy (HAART era, there has been a significant decline in the incidence of AIDS-associated primary central nervous system lymphoma (PCNSL. However, only a modest decrease in incidence has been reported for other AIDS-NHL subtypes. Thus, AIDS-NHLs remain a significant cause of morbidity and mortality in HIV infected individuals. Recently, much attention has been directed toward the role of miRNAs in cancer, including NHL. Several miRNAs, including those encoded by the miR-17-92 polycistron, have been shown to play significant roles in B cell tumorigenesis. However, the role of miRNAs in NHL in the setting of HIV infection has not been defined.We used quantitative realtime PCR to assess the expression of miRNAs from three different paralog clusters, miR-17-92, miR-106a-363, and miR-106b-25 in 24 cases of AIDS-NHLs representing four tumor types, Burkitt's lymphoma (BL, n = 6, diffuse large B-cell lymphoma (DLBCL, n = 8, primary central nervous system lymphoma (PCNSL, n = 5, and primary effusion lymphoma (PEL, n = 5. We also used microarray analysis to identify a differentiation specific miRNA signature of naïve, germinal center, and memory B cell subsets from tonsils (n = 4. miRNAs from the miR-17-92 paralog clusters were upregulated by B cells, specifically during the GC differentiation stage. We also found overexpression of these miRNA clusters in all four AIDS-NHL subtypes. Finally, we also show that select miRNAs from these clusters (miR-17, miR-106a, and miR-106b inhibited p21 in AIDS-BL and DLBCL cases, thus providing a mechanistic role for these miRNAs in AIDS-NHL pathogenesis.Dysregulation of miR-17-92 paralog clusters is a common feature of AIDS-associated NHLs.

    Nasal type natural killer/T-cell lymphoma is a rare type of extranodal non-Hodgkin lymphoma which originates from nasal cavity and paranasal sinuses. Exact diagnosis of nasal natural killer/T-cell lymphoma, which is a rapidly progressive clinical condition, may be established by immunohistochemical analysis on biopsy material after clinical suspicion. In this article, we report four cases of nasal natural killer/T-cell lymphoma who were followed-up in our clinic and discuss the diagnosis and treatment of the disease in light of the literature data.

    Lymphomas are the most common non-epithelial tumors of the head and neck and its incidence has increased in recent decades. Around 10% are extranodal lymphomas, and in more than half of the cases are located in Waldeyer's lymphatic ring. The most common presenting symptoms are odynophagia and dysphagia (68%), and symptoms suggestive of oropharyngeal cancer such as cough, hoarseness, earache, feeling of occupation in the back of the mouth, throat or neck. In non-Hodgkin lymphomas in this location, B symptoms (weight loss, fever and sweating) are rare (5%). The histological subtype of each individual lymphoma affects the evaluation, therapy and prognosis. Copyright © 2012 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Deregulated MYC is found in about half of human tumors, being more prevalent in hematological neoplasms. Deregulation mechanisms include chromosomal translocation (particularly in lymphoma, amplification, and hyperactivation of MYC transcription. Here we review MYC involvement in the major types of leukemia and lymphoma. MYC rearrangements appear in all Burkitt lymphomas and are common in other lymphoma types, whereas in acute lymphoblastic leukemia, acute myeloid leukemia, lymphoproliferative, and myeloproferative diseases, they are less frequent. However, MYC overexpression is present in all types of hematological malignancies and often correlates with a worse prognosis. Data in leukemia-derived cells and in animal models of lymphomagenesis and leukemogenesis suggest that MYC would be a good therapeutic target. Several MYC-directed therapies have been assayed in preclinical settings and even in clinical trials. First, peptides and small molecules that interrupt the MYC–MAX interaction impair MYC-mediated tumorogenesis in several mouse models of solid tumors, although not yet in lymphoma and leukemia models. Second, there are a number of small molecules inhibiting the interaction of MYC–MAX heterodimers with DNA, still in the preclinical research phase. Third, inhibitors of MYC expression via the inhibition of BRD4 (a reader of acetylated histones have been shown to control the growth of MYC-transformed leukemia and lymphoma cells and are being used in clinic trials. Finally, we review a number of promising MYC

    Nine cases of primary intracranial malignant lymphoma, which accounts for 3.3 % of all intracranial tumors seen in the authors' institution, were studied in terms of diagnostic computed tomographic (CT) features, the tumors' histologic appearance, treatment, post-treatment blood immunologic and cerebrospinal fluid (CSF) characteristics, and outcome. The patients were seven males and two females aged 42 to 67 years. Their chief signs and symptoms on admission were intracranial hypertension, focal signs, and disturbance of consciousness. CT, which proved the most useful preoperative diagnostic technique, demonstrated multiple lesions in seven cases and, in all cases, regions of isodensity or slight high density that were enhanced by contrast medium. According to the patterns of enhancement, the tumors were classed as diffuse (three cases) or nodular (six cases). The former is considered typical of malignant lymphoma, whereas the latter type was sometimes indistinguishable from metastatic tumor and meningioma. At surgery, one patient underwent radical tumor excision, two partial removal, and six biopsy only. Histologic examination revealed one tumor to be of the diffuse small cell type, three of the medium cell type, and five of the large cell type (Lymphoma Study Group classification). Of seven tumors in which lymphocytes were examined by peroxidase-antiperoxidase staining, four were of the B cell type. Postoperatively, whole brain irradiation with 29 to 46 Gy was followed by local irradiation with 15 to 50 Gy. If the tumor persisted, one of three chemotherapies was administered. In one case, methotrexate was given intrathecally. Seven patients were divided into two groups: long remission (three) and recurrence (four). These two groups were compared in terms of serum immunoglobulin levels, T and B cell ratios, CSF characteristics, CT features, tumor cell type, and treatment. No clear differences were found.

    Full Text Available Abstract Background Mantle cell lymphoma (MCL is a rare variety of non-Hodgkin's lymphoma which originates from CD5+ B-cell population in the mantle zones of lymphoid follicles. Coexistence of such tumours in the axillary lymph nodes with invasive breast cancers without prior history of adjuvant chemotherapy or radiotherapy has not been previously reported in literature. Case report We report a rare case of breast cancer co-existing with stage I mantle cell lymphoma of the ipsilateral axillary lymph node detected fortuitously by population screening. Conclusion Though some studies have tried to prove breast carcinomas and lymphomas to share a common molecular or viral link, more research needs to be done to establish whether such a link truly exists.

    Full Text Available Acute renal failure (ARF in patients with malignancy occurs due to causes such as prerenal, renal and post renal as in normal population. Tumor infiltration of kidneys is usually uncommon. However, renal function may be impaired in fast-growing hematological malignancies such as acute leukemia or lymphoma, depending on tumor involvement. Herein, we presented a case of ARF and later diagnosed as B-cell Non-Hodgkin's lymphoma. 54-year-old male patient was admitted due to ARF. Although development of ARF due to tumor infiltration is rare, in cases who did not have risk factors for development of ARF, leukemic or lymphomatous infiltration should be considered.

    Full Text Available The treatment of patients with non- Hodgkin’s lymphoma (NHL is often the treatment of elderly patients, as most patients are older than 65 years at diagnosis. These elderly patients present particular therapeutic challenges, because they may be more frail and at greater risk of treatment-related toxicity, especially anthracycline-related cardiotoxicity, than younger patients. The following two case studies illustrate the challenges and therapeutic decision-making in managing elderly patients with an aggressive and an indolent form of lymphoma.

    Full Text Available Primary malignant lymphomas in the female genital tract are rare. Most cases are non-Hodgkin lymphomas of which diffuse large B-cell lymphomas are most commonly seen. Symptoms are associated with other, more common diseases; therefore, a doctors’ delay can be expected. In this case a woman presented with complaints of urinary obstruction due to a large tumour in the pelvic area. A laparotomy was performed. A very large tumour of the uterus was found with adherence to the pelvic wall and urinary bladder. Diagnostic histological examination showed a diffuse large B-cell lymphoma. Treatment with R-CHOP chemotherapy was started shortly after the operation. The treatment of patients with a primary malignant lymphoma of the uterus should be individualized with the following options: surgery, radiotherapy and/or chemotherapy.

    Comparative genome-wide expression profiling of malignant tumor counterparts across the human-mouse species barrier has a successful track record as a gene discovery tool in liver, breast, lung, prostate and other cancers, but has been largely neglected in studies on neoplasms of mature B-lymphocytes such as diffuse large B cell lymphoma (DLBCL) and Burkitt lymphoma (BL). We used global gene expression profiles of DLBCL-like tumors that arose spontaneously in Myc-transgenic C57BL/6 mice as a phylogenetically conserved filter for analyzing the human DLBCL transcriptome. The human and mouse lymphomas were found to have 60 concordantly deregulated genes in common, including 8 genes that Cox hazard regression analysis associated with overall survival in a published landmark dataset of DLBCL. Genetic network analysis of the 60 genes followed by biological validation studies indicate FOXM1 as a candidate DLBCL and BL gene, supporting a number of studies contending that FOXM1 is a therapeutic target in mature B cell tumors. Our findings demonstrate the value of the “mouse filter” for genomic studies of human B-lineage neoplasms for which a vast knowledge base already exists. PMID:24130802

    Epigenetic inactivation of tumor suppressor genes (TSG) by promoter CpG island hypermethylation is a hallmark of cancer. To assay its extent in human lymphoma, methylation of 24 TSG was analyzed in lymphoma-derived cell lines as well as in patient samples. We screened for TSG methylation using methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) in 40 lymphoma-derived cell lines representing anaplastic large cell lymphoma, Burkitt lymphoma (BL), diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), Hodgkin lymphoma and mantle cell lymphoma (MCL) as well as in 50 primary lymphoma samples. The methylation status of differentially methylated CD44 was verified by methylation-specific PCR and bisulfite sequencing. Gene expression of CD44 and its reactivation by DNA demethylation was determined by quantitative real-time PCR and on the protein level by flow cytometry. Induction of apoptosis by anti-CD44 antibody was analyzed by annexin-V/PI staining and flow cytometry. On average 8 ± 2.8 of 24 TSG were methylated per lymphoma cell line and 2.4 ± 2 of 24 TSG in primary lymphomas, whereas 0/24 TSG were methylated in tonsils and blood mononuclear cells from healthy donors. Notably, we identified that CD44 was hypermethylated and transcriptionally silenced in all BL and most FL and DLBCL cell lines, but was usually unmethylated and expressed in MCL cell lines. Concordant results were obtained from primary lymphoma material: CD44 was not methylated in MCL patients (0/11) whereas CD44 was frequently hypermethylated in BL patients (18/29). In cell lines with CD44 hypermethylation, expression was re-inducible at mRNA and protein levels by treatment with the DNA demethylating agent 5-Aza-2'-deoxycytidine, confirming epigenetic regulation of CD44. CD44 ligation assays with a monoclonal anti-CD44 antibody showed that CD44 can mediate apoptosis in CD44 + lymphoma cells. CD44 hypermethylated, CD44 - lymphoma cell lines were consistently

    Micro RNAs (miRNAs) are a conserved class of small noncoding RNAs (22-25 nucleotides), which modulate gene expression at post-transcriptional level by base pairing to the 3'UTR of the target mRNAs, thus causing messenger degradation or inhibiting its translation. Experimental evidence indicate that several miRNAs are deregulated in human tumors. MIRN155 has been shown to be highly expressed in a variety of human B cell lymphomas, especially diffuse large B cells, Hodgkin, and a subset of Burkitt lymphomas. Its expression is physiologically increased in activated B and T cells and it plays a key role in regulating the homeostasis and function of the immune system

    In 1964, Epstein, Barr, and Achong published a report outlining their discovery of viral particles in lymphoblasts isolated from a patient with Burkitt lymphoma. The Epstein-Barr virus (EBV) was the first human cancer virus to be described, and its discovery paved the way for further investigations into the oncogenic potential of viruses. In the decades following the discovery of EBV, multinational research efforts led to the discovery of further viral causes of various human cancers. Lymphomas are perhaps the cancer type that is most closely associated with oncogenic viruses: infection with EBV, human T-lymphotropic virus 1 (HTLV-1), human immunodeficiency virus (HIV), Kaposi sarcoma-associated herpesvirus/human herpesvirus 8, and hepatitis C virus have all been associated with lymphomagenesis. Lymphomas have also played an important role in the history of oncoviruses, as both the first human oncovirus (EBV) and the first human retrovirus (HTLV-1) were discovered through isolates taken from patients with unique lymphoma syndromes. The history of the discovery of these 2 key oncoviruses is presented here, and their impact on further medical research, using the specific example of HIV research, is briefly discussed.

    Full Text Available Abstract Aims To analyze the relationship between exposure to chlorinated and aromatic organic solvents and malignant lymphoma in a multi-centre, population-based case-control study. Methods Male and female patients with malignant lymphoma (n = 710 between 18 and 80 years of age were prospectively recruited in six study regions in Germany (Ludwigshafen/Upper Palatinate, Heidelberg/Rhine-Neckar-County, Würzburg/Lower Frankonia, Hamburg, Bielefeld/Gütersloh, and Munich. For each newly recruited lymphoma case, a gender, region and age-matched (± 1 year of birth population control was drawn from the population registers. In a structured personal interview, we elicited a complete occupational history, including every occupational period that lasted at least one year. On the basis of job task-specific supplementary questionnaires, a trained occupational physician assessed the exposure to chlorinated hydrocarbons (trichloroethylene, tetrachloroethylene, dichloromethane, carbon tetrachloride and aromatic hydrocarbons (benzene, toluene, xylene, styrene. Odds ratios (OR and 95% confidence intervals (CI were calculated using conditional logistic regression analysis, adjusted for smoking (in pack years and alcohol consumption. To increase the statistical power, patients with specific lymphoma subentities were additionally compared with the entire control group using unconditional logistic regression analysis. Results We observed a statistically significant association between high exposure to chlorinated hydrocarbons and malignant lymphoma (Odds ratio = 2.1; 95% confidence interval 1.1–4.3. In the analysis of lymphoma subentities, a pronounced risk elevation was found for follicular lymphoma and marginal zone lymphoma. When specific substances were considered, the association between trichloroethylene and malignant lymphoma was of borderline statistical significance. Aromatic hydrocarbons were not significantly associated with the lymphoma diagnosis

    Full Text Available Although suicide among childhood cancer survivors is rare, there is still a significantly higher risk in this population than in healthy adolescents. A 17-year-old girl cured of Burkitt lymphoma committed suicide after completing her treatment. She had never previously shown signs of psychological suffering and was in good general health. This case made the operators wonder how this tragic possibility might be prevented. It is essential for the ongoing monitoring of the psychological and social suffering of young people during follow-up programs to be assured by a multidisciplinary team involved in the patient′s global care.

    A primary mucosa-associated lymphoid tissue lymphoma (MALT lymphoma) of the breast is extremely rare. We report a case of a MALT lymphoma of the breast that presented as a palpable left breast mass in a 37-year-old woman. A physical examination revealed a large firm, and fixed mass in the left inner breast. Mammograms showed a large, isodense mass in the lower inner quadrant of the left breast and an enlarged lymph node in the axilla. A sonogram demonstrated a 5 cm sized, oval, circumscribed, and heterogeneously hypoechoic mass with posterior acoustic enhancement. A surgical biopsy was performed, and the pathology revealed a MALT lymphoma.

    Full Text Available Primary effusion lymphoma (PEL is a unique form of non-Hodgkin lymphoma, usually seen in severely immunocompromised, HIV-positive patients. PEL is related to human herpesvirus-8 (HHV-8 infection, and it usually presents as a lymphomatous body cavity effusion in the absence of a solid tumor mass. There have been very few case reports of HIV-positive patients with HHV-8-positive solid tissue lymphomas not associated with an effusion (a solid variant of PEL. In the absence of effusion, establishing an accurate diagnosis can be challenging, and a careful review of morphology, immunophenotype, and presence of HHV-8 is necessary to differentiate from other subtypes of non-Hodgkin lymphoma. Treatment involves intensive chemotherapy, and prognosis is usually poor. We present a rare case of a PEL variant in an HIV-positive patient who presented with extensive lymphadenopathy without any associated effusions.

    2012-02-03

    INTRODUCTION: Patients with Type 1 diabetes mellitus have a high prevalence of coeliac disease, symptoms of which are often mild, atypical, or absent. Untreated coeliac disease is associated with an increased risk of malignancy, particularly of lymphoma. We describe four patients with Type 1 diabetes mellitus and coeliac disease who developed lymphoma. CASE REPORTS: Two patients were male and two female. In three patients, coeliac disease and lymphoma were diagnosed simultaneously. Enteropathy-associated T cell lymphoma occurred in two patients, Hodgkin\\'s disease in one, and B cell lymphoma in one. Response to treatment was in general poor, and three patients died soon after the diagnosis of lymphoma was made. CONCLUSION: As the relative risk of lymphoma is reduced by a gluten-free diet, a high index of suspicion for coeliac disease should exist in all Type 1 diabetic patients with unexplained constitutional or gastrointestinal symptoms.

    Full Text Available We report the case of a 38-year-old man who developed vanishing bile duct syndrome in association with Hodgkin's lymphoma. He was noted to have cervical lymphadenopathy and marked elevation of total serum bilirubin at diagnosis. He achieved complete remission with normalization of serum bilirubin after eight courses of Adriamycin, bleomycin, vinblastine, and dacarbazine chemotherapy followed with autologous hematopoietic cell transplantation. Consecutive liver biopsies performed at diagnosis and at the stage of complete remission revealed the disappearance and regeneration of interlobular bile ducts, respectively. Our case provides pathological evidence that Hodgkin's lymphoma-related vanishing bile duct syndrome is a reversible bile duct injury disease. Bilirubin is a reliable serum marker to monitor the treatment response of these cases. The mechanism to develop hyperbilirubinemia with vanishing bile duct in such a case of Hodgkin's lymphoma remains to be studied. A literature review was carried out.

    The anti-CD20 monoclonal antibody (Ab) rituximab is accepted to be an effective therapeutic Ab for malignant B-cell lymphoma; however, discovery of other cell surface antigens is required for the option of antibody medicine. Considering that many tumor-associated antigens are glycans, we have searched glycoconjugates for the candidate antigens that therapeutic Abs target. To this end, we first focused on the difference in the glycogenes expression in terms of Epstein-Barr virus (EBV) infection of a Burkitt's lymphoma cell line, Akata. Using DNA array, flow cytometry and Western blotting, we found that Thy1 was highly expressed in EBV-positive Akata cells. Subsequently, Thy1 was found to be expressed in other B-cell lymphoma cell lines: BJAB, MutuI, and MutuIII, irrespective of EBV infection. Treatment of these cells with an anti-Thy1 monoclonal antibody inhibited proliferation more strongly than the therapeutic Ab rituximab. The B-cell lymphoma cell lines were classified based on the extent of the proliferation inhibition, which was not correlated with the expression level of Thy1. It is suggested that stable residence of receptor tyrosine kinases in lipid rafts sustains cell growth in B-cell lymphoma cells.

    Full Text Available Introduction. The presence of bilateral exophthalmos and palpebral, periorbital edema associated with hyperthyroidism is most often considered as an initial sign of Graves’ ophthalmopathy. However, in up to 20% of cases, Graves’ ophthalmopathy might precede the occurrence of hyperthyroidism, which is very important to be considered in the differential diagnosis, especially if it is stated as unilateral. Among other less common causes of non-thyroid-related orbitopathy, orbital lymphoma represents rare conditions. We presented of a patient with Graves’ disease, initially manifested as bilateral orbitopathy and progressive unilateral exophthalmos caused by the marginal zone B-cell non-Hodgkin lymphoma of the orbit. Case report. A 64-yearold man with the 3-year history of bilateral Graves’ orbitopathy and hyperthyroidism underwent the left orbital decompression surgery due to the predominantly left, unilateral worsening of exophthalmos resistant to the previously applied glucocorticoid therapy. A year after the surgical treatment, a substantial exophthalmos of the left eye was again observed, signifying that other non-thyroid pathology could be involved. Orbital ultrasound was suggestive of primary orbital lymphoma, what was confirmed by orbital CT scan and the biopsy of the tumor tissue. Detailed examinations indicated that the marginal zone B-cell non-Hodgkin lymphoma extended to IV - B-b CS, IPI 3 (bone marrow infiltration: m+ orbit+. Upon the completion of the polychemiotherapy and the radiation treatment, a complete remission of the disease was achieved. Conclusion. Even when elements clearly indicate the presence of thyroid-related ophthalmopathy, disease deteriorating should raise a suspicion and always lead to imaging procedures to exclude malignancy.

    2012-01-01

    Full Text Available Primary bilateral non-Hodgkin's lymphoma (NHL of the adrenal gland is a very rare entity. Indeed less than 60 cases have been reported in the literature. Hence, we report a case of high-grade lymphoma of both adrenal glands that was found in a young patient of 32 years of age. The patient was admitted in the emergency department of our hospital with a profile of hemorrhagic shock. After stabilization, the imaging investigations demonstrated large bilateral adrenal masses. The CT-scan guided biopsy of both adrenal glands allowed the diagnosis of primary bilateral adrenal NHL. The patient died after the first chemotherapy session. The presence of bilateral adrenal masses associated with a rapid increase of volume should raise the diagnosis of primary adrenal non-Hodgkin's lymphoma.

    Full Text Available Abstract Introduction Non-Hodgkin lymphoma primarily originating from the bone is exceedingly rare. To our knowledge, this is the first report of primary bone lymphoma presenting with progressive cord compression from an origin in the cervical spine. Herein, we discuss the unusual location in this case, the presenting symptoms, and the management of this disease. Case presentation We report on a 23-year-old Caucasian-American man who presented with two months of night sweats, fatigue, parasthesias, and progressive weakness that had progressed to near quadriplegia. Magnetic resonance (MR imaging demonstrated significant cord compression seen primarily at C7. Surgical management, with corpectomy and dorsal segmental fusion, in combination with adjuvant chemotherapy and radiation therapy, halted the progression of the primary disease and preserved neurological function. Histological analysis demonstrated an aggressive anaplastic large cell lymphoma. Conclusion Isolated primary bony lymphoma of the spine is exceedingly rare. As in our case, the initial symptoms may be the result of progressive cervical cord compression. Anterior corpectomy with posterolateral decompression and fusion succeeded in preventing progressive neurologic decline and maintaining quality of life. The reader should be aware of the unique presentation of this disease and that surgical management is a successful treatment strategy.

    Primary cutaneous B-cell lymphoma (CBCL) is a very low prevalence neoplasm and constitutes 25% of all primary cutaneous lymphomas. Our objective was to discover the epidemiological, clinic and histologic characteristics of CBCL in our area. Retrospective descriptive study with patients with histologic diagnosis of CBCL followed up in our department between 2004 and 2015. Twenty-two patients with CBCL were included; 65% were men and 35% were women. Follicle centre lymphoma was the most common subtype (41%). Only 3 cases presented with node involvement and one with bone marrow invasion. Five recurrences were detected and one patient died because of the CBCL. This is one of the first CBCL series in theSpanish population. The incidence, sex, age, subtype distribution, clinical features and immunohistochemical patterns are very similar to those of the other series. Copyright © 2016 Elsevier España, S.L.U.

    Full Text Available Lymphomas occur by clonal expansion of lymphoid cells and have distinctive morphological and immunophenotypic features. Determination of canine lymphoma immunophenotype is useful for accurate prognosis and further therapy. In the suggested study, we performed an immunohistochemical evaluation of some cases with canine lymphoma diagnosed in the Department of Pathology (Faculty of Veterinary Medicine, Cluj-Napoca, Romania, in order to characterize them. The investigation included 39 dogs diagnosed with different anatomical forms of lymphoma, following necropsy analysis or assessment of biopsies. The diagnosis of lymphoma was confirmed by necropsy and histopathology (Hematoxylin-eosin stain examinations. The collected specimens were analyzed by immunohistochemistry technique (automatic method using the following antibodies: CD3, CD20, CD21 and CD79a. The analyzed neoplasms were characterized as follows: about 64.10% of cases were diagnosed as B-cell lymphomas, 33.34% of cases as T-cell lymphomas, whereas 2.56% of cases were null cell type lymphomas (neither B nor T. Most of multicentric (80%, mediastinal (60% and primary central nervous system lymphomas (100% had B immunophenotype, while the majority of cutaneous (80% and digestive (100% lymphomas had T immunophenotype. Immunohistochemical description of canine lymphomas can deliver some major details concerning their behavior and malignancy. Additionally, vital prognosis and efficacy of some therapeutic protocols are relying on the immunohistochemical features of canine lymphoma.

    We describe the case of a 57-year-old man who was referred to us with persistent sore throat, dysphagia, and enlarged tonsils. He had not responded to earlier treatment with antibiotic therapy and other routine measures. In view of the persistent nature of the patient\\'s symptoms and the tonsillar hypertrophy, we decided to perform a tonsillectomy and to send the excised specimens for pathologic analysis. Histologic evaluation identified non-Hodgkin lymphoma in both tonsils. The patient was treated with postoperative chemo- and radiotherapy, and he was free of symptoms during 18 months of follow-up. To the best of our knowledge, only 4 cases of bilateral non-Hodgkin lymphoma of the tonsils have been reported in the English-language literature. We also discuss the importance of histologic analysis of excised tonsil tissue in selected cases.

    Abstract We report an unusual case of HIV-related immune reconstitution inflammatory syndrome, presenting as suspected AIDS-related lymphoma. Symptoms, initial investigations including fine-needle biopsy and 18F-FDG PET/CT scan were highly compatible with high grade AIDS-related lymphoma, however subsequently IRIS was diagnosed. We discuss pitfalls in the interpretation of diagnostic results in ARL versus IRIS.

    Gastric MALT lymphoma is a distinct entity related to Helicobacter pylori gastritis. Some studies suggest a role for trisomy 3 in the genesis of these lymphomas, but they mainly focused on low-grade MALT lymphoma. Gastric MALT lymphoma, however, comprises a spectrum from low- to high-grade cases.

    We attempt to correlate the histological types [in three cases of B-cell non-Hodgkin's lymphoma (NHL), one case of T-cell NHL and one of Hodgkin's disease] with the radiological presentation and compare our findings with the literature reviewed. Among the mammographic studies, performed over and 18-month period, we have assessed five patients (four women and one man, aged as having lymphoma. the man presented bilateral involvement. Both mammography and a broader study with ultrasound and chest and abdominal CT scan were performed in every case. Four patients underwent breast ultrasound. The definitive diagnosis was based on biopsy in all cases. Three of the five cases involved primary lymphomas and the other two were secondary. Four patients presented NHL and the remaining patient had Hodgkin's disease. In mammography, the nodules showed different degrees of margin definition. In ultrasound, all the lesion were hypoechoic. The radiological diagnosis of breast lymphoma is difficult in the absence of a previous diagnosis of lymphoma. This lesion should be included in the differential diagnosis in the presence of a breast nodule associated with axillary lymph nodes, especially when the latter are bilateral. (Author)

    Full Text Available Introduction. Polymyalgia rheumatica (PMR is one of the most common inflammatory rheumatism types in elderly population. The link between cancer and PMR is a matter of debate. Methods. We report two cases of PMR leading to the diagnosis of lymphoma and the growing interest of PET-TDM in this indication. Results. A 84-year-old man known for idiopathic neutropenia presented an inflammatory arthromyalgia of the limb girdle since one month. Blood exams highlighted the presence of a monoclonal B cell clone. Bone marrow concluded to a B cell lymphoma of the marginal zone. He was successfully treated with 0.3 mg/kg/d of prednisone, and response was sustained after 6 months. A 73-year-old man known for prostatic neoplasia in remission for 5 years presented arthromyalgia of the limb girdle since one month. PET-CT revealed bursitis of the hips and the shoulders, no prostatic cancer recurrence, and a metabolically active iliac lymphadenopathy whose pathologic exam concluded to a low grade follicular lymphoma. He was successfully treated with 0.3 mg/kg/d of prednisone. Conclusion. These observations may imply that lymphoma is sometimes already present when PMR is diagnosed and PET-CT is a useful tool in the initial assessment of PMR to avoid missing neoplasia.

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL can arise from lymphatic cells located in solid organs (extranodal and it accounts for 25 to 35% of all NHL. Primary lymphoma on the female genital tract (PLFGT is a rare disease, comprising 0.2 to 1.1% of all extranodal lymphomas in the female population. In this paper, the authors report an extremely rare case of a 48-year-old woman who exhibited an abnormal uterine bleeding, pelvic pain, and dysmenorrhea history. The transvaginal ultrasound showed an anteverted uterus measuring 153 cm3 in volume, with intramural leiomyomas. She underwent a total laparoscopic hysterectomy with bilateral salpingectomy. The histologic evaluation of the specimen showed a follicular lymphoma with diffuse pattern in the endometrium. This report illustrates the difficulty in the diagnosis of primary lymphomas of the female genital tract.

    We describe the case a spinal cord localization of neurological toxoplasmosis in a HIV-positive patient with Burkitt lymphoma, previously treated with chemotherapy and immunotherapy. This complication occurred while patient was in complete remission of lymphoma, with CD4+ T cell count of 270 /ml, undetectable HIV viremia, and despite the trimethoprim/ sulfamethoxazole prophylaxis. Indeed, we hypothesize that in our patient neurologic toxoplasmosis has been fostered more by previous immuno-chemotherapy than by HIV- related immunodeficiency. On the whole, this case suggests that parameters usually employed to predict the risk for opportunistic infections in HIV-positive people might not apply to patients with HIV-related lymphomas.

    Peripheral T-cell lymphomas (PTCLs) are aggressive neoplasms which may involve the liver. The imaging manifestations of hepatic lymphoma are highly variable and show overlapping appearances of numerous other hepatic diseases. As the management and prognosis of lymphoma differ markedly from those of other malignant diseases, prompt diagnosis and early effective treatment are very important. Here, we report an atypical case of primary PTCL not otherwise specified involving the liver that exhibited a solitary hepatic mass mimicking hepatocellular carcinoma (HCC) on CT. Liver biopsy is not commonly recommended in highly suspicious cases of HCC. However, in a patient without risk factors for HCC, consideration of other diagnostic possibilities is required and needle biopsy may be a more rational choice. An imaging approach, based on a careful review of clinical and laboratory findings is essential to prevent false-positive diagnosis of HCC and subsequent invasive treatment.

    Full Text Available Most bladder tumors are epithelial in origin. Nonepithelial cancers are rarely located in the bladder. Sarcomas are the most common malignancies among nonepithelial cancers. Primary bladder lymphoma is rare and mostly low grade. Here, we have reported a case of diffuse large cell lymphoma of the bladder. The patient, a 64-year-old man, had urinary frequency for 18 months. Abdominal sonography indicated a thick bladder wall and transurethral biopsy showed diffuse large cell lymphoma. Immunohistochemistry (IHC results showed that the tumor was positive for CD20, CD45, and Pax-5 and negative for BCL-2, cytokeratin, and S100. He had a normal bone marrow biopsy, abdominal, pelvic and chest CT scans. He had no B symptoms. The patient received 6 cycles of R-CHOP followed by radiotherapy (36 Gy to the pelvis. Six months after treatment, the patient is well and has returned to work. We have searched PubMed for primary diffuse large cell lymphoma. Primary diffuse large cell lymphoma of the bladder is best treated according to treatment for diffuse large cell lymphoma of other sites, which includes chemotherapy and radiotherapy. As seen in our review, primary diffuse large cell lymphoma of the bladder has a similar clinical course to diffuse large cell lymphoma of other sites.

    Primary malignant lymphoma of bone, so-called Parker-Jackson reticulosarcoma, is a rare form of extranodal lymphoma with a relatively good prognosis. It often corresponds to B-cell lymphoma of high-grade malignancy. We report a case of mu lambda immunoblastic lymphoma showing two distinctive features: an abundant reactive T-lymphocytic population and unusual intra-cytoplasmic inclusions. These inclusions were PAS positive and consisted of monotypic mu lambda immunoglobulin localized in peculiar aggregates of rough endoplasmic reticulum. Their morphological appearances resembled the well-documented inclusions described in some varieties of non-Hodgkin's lymphoma.

    Intravascular lymphoma is a rare subtype of extranodal Non-Hodgkin's lymphoma. Its prognosis is poor in a high percentage of cases due to its insidious appearance and low clinical suspicion. Its diagnosis is usually only reached after an autopsy. It may affect different organs as a whole or only one organ. It is extremely rare that the lung is the only damaged organ. Its diagnosis depends of the clinician's suspicion and proper evaluation with imaging studies as well as correct selection of the organ to be biopsied. When detected on time, the treatment of choice is a combination of a series of chemotherapy associated to a monoclonal antibody (anti-CD20). We present the case of a male patient who underwent a positron emission tomography-computed tomography with 2-[F-18]-fluoro-2 deoxy-D-glucose (FDG) due to symptoms suggestive of a lymphoproliferative disease with no clear structural abnormalities. The images led to a diagnosis of pulmonary intravascular large B cell lymphoma. Copyright © 2012 Elsevier España, S.L. and SEMNIM. All rights reserved.

    Fifteen patients with primary gastric malignant lymphoma who underwent radiotherapy were examined. Median age was 68 years, and male to female ratio was 1:2. All the cases were stage I including 7 cases of diffuse large B-cell lymphoma (DLBCL), 7 cases of MALT lymphoma, and 1 case of follicular lymphoma. Therapy methods were as follows. For DLBCL, 30 Gy of radiotherapy was performed after chemotherapy. For six cases of MALT lymphomas, 30 Gy of radiotherapy was performed. For one patient diagnosed as high-grade gastric MALT lymphoma was treated in the same way as DLBCL. For one patient with follicular lymphoma, 30 Gy of radiotherapy was performed. The radiotherapy was applied with 3-dimensional fixed multi-portal irradiation, with the reduced irradiation of the liver and kidney. There was no recurrence of disease in all cases, and all patients have been alive, and no-recurrence living periods are 20 to 120 months. There was no harmful adverse event, and the tumor had disappeared with 30 Gy of radiation therapy in all cases. Considering the occurrence of secondary cancer, it was considered that a dosage of more than 30 Gy was not necessary for primary gastric malignant lymphoma. (J.P.N.)

    Follicular lymphoma (FL) is an indolent lymphoma that transforms to high-grade lymphoma, mostly diffuse large B-cell lymphoma, in about a third of patients. We present the first report of a case of FL that transformed to plasmablastic lymphoma (PBL). Clonal transformation of the FL to PBL was evidenced by identical IGH/BCL2 gene rearrangements and VDJ gene usage in rearranged IGH genes. IGH/ BCL2 translocation was retained in the PBL, which also acquired c-myc gene rearrangement. Genealogic analysis based on somatic hypermutation of the rearranged IGH genes of both FL and PBL suggests that transformation of the FL to PBL occurred most likely by divergent evolution from a common progenitor cell rather than direct evolution from the FL clone. Our study of this unusual case expands the histologic spectrum of FL transformation and increases our understanding of the pathogenetic mechanisms of transformation of indolent lymphomas to aggressive lymphomas.

    The anti-CD20 monoclonal antibody (Ab) rituximab is accepted to be an effective therapeutic Ab for malignant B-cell lymphoma; however, discovery of other cell surface antigens is required for the option of antibody medicine. Considering that many tumor-associated antigens are glycans, we have searched glycoconjugates for the candidate antigens that therapeutic Abs target. To this end, we first focused on the difference in the glycogenes expression in terms of Epstein-Barr virus (EBV) infection of a Burkitt's lymphoma cell line, Akata. Using DNA array, flow cytometry and Western blotting, we found that Thy1 was highly expressed in EBV-positive Akata cells. Subsequently, Thy1 was found to be expressed in other B-cell lymphoma cell lines: BJAB, MutuI, and MutuIII, irrespective of EBV infection. Treatment of these cells with an anti-Thy1 monoclonal antibody inhibited proliferation more strongly than the therapeutic Ab rituximab. The B-cell lymphoma cell lines were classified based on the extent of the proliferation inhibition, which was not correlated with the expression level of Thy1. It is suggested that stable residence of receptor tyrosine kinases in lipid rafts sustains cell growth in B-cell lymphoma cells.

    Full Text Available Abstract Background Mantle cell lymphoma (MCL is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. Extra nodal involvement is present in the majority of cases, with a peculiar tendency to invade the gastro-intestinal tract in the form of multiple lymphomatous polyposis. MCL can be accurately diagnosed with the use of the highly specific marker Cyclin D1. Few cases of mantle cell lymphoma presenting with intussuception have been reported. Here we present a rare case of multiple intussusceptions caused by mantle cell lymphoma and review the literature of this disease. Case presentation A 68-year-old male presented with pain, tenderness in the right lower abdomen, associated with nausea and non-bilious vomiting. CT scan of abdomen revealed ileo-colic intussusception. Laparoscopy confirmed multiple intussusceptions involving ileo-colic and ileo-ileal segments of gastrointestinal tract. A laparoscopically assisted right hemicolectomy and extended ileal resection was performed. Postoperative recovery was uneventful. The histology and immuno-histochemistry of the excised small and large bowel revealed mantle cell lymphoma with multiple lymphomatous polyposis and positivity to Cyclin D1 marker. The patient was successfully treated with Rituximab-CHOP chemotherapy and remains in complete remission at one-year follow-up. Conclusion This is a rare case of intestinal lymphomatous polyposis due to mantle cell lymphoma presenting with multiple small bowel intussusceptions. Our case highlights laparoscopic-assisted bowel resection as a potential and feasible option in the multi-disciplinary treatment of mantle cell lymphoma.

    Full Text Available In 2005, the World Health Organization - European Organization for Research and Treatment of Cancer (WHOEORTC classified cutaneous B-cell lymphomas into 4 categories: primary cutaneous marginal zone B-cell lymphoma (PCMZL, primary cutaneous follicle center lymphoma (PCFCL, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL-LT, and primary cutaneous diffuse large B-cell lymphoma, other (PCDLBCL-O. The absence of evident extra-cutaneous disease is a necessary condition for the diagnosis of primary cutaneous B-cell lymphomas, because they have a completely different clinical behavior and prognosis from their nodal counterparts. PCDLBCL-O basically represents a morphological variation, lacking the typical features of PCDLBCLLT, neither confirming the definition of PCFCCL, but on the clinical ground, its behavior seems at least to partially overlap the indolent course of PCFCCL. In fact, the present WHO lymphoma classification from 2008 overcame the previous WHO-EORTC classification, including at least a part of PCDLBCL-O within the spectrum of PCFCCL. However, owing to the rarity and heterogeneity of the PCDLBCL-O, the precise clinicopathological characteristics have not been well characterized and the optimal treatment for this group of lymphomas is yet to be defined. Nevertheless, dermatologists and pathologists should be aware of this entity in order to avoid unnecessary aggressive treatment. We present a case of a 46-year-old Caucasian male with one large round-shaped tumor and a few scattered nodules localized on the back. The histopathological features of the lesion corresponded to PCDLBCL-O. The patient follow-up showed that he was disease-free three months after surgical excision of the lesions and adjuvant local radiotherapy. No additional therapy was introduced, including chemotherapy with rituximab, cyclophosphamide, doxorubicin hydrochloride, oncovin, prednisolone (R-CHOP.

The present study describes a rare case of mucosa-associated lymphoid tissue (MALT) lymphoma, which was initially misdiagnosed as eosinophilic pneumonia. The initial diagnosis was formed based on the results of chest radiography, peripheral eosinophilia tests and bronchoalveolar lavage, and the clinical course of the patient. Following administration of methylprednisolone (40 mg/day) for 4 days and oral administration of prednisolone (30 mg/day), the clinical course rapidly improved and the eosinophil count immediately decreased a to normal level. However, abnormal shadows observed on computed tomography (CT) scans of the chest did not diminish. At 6 months after the initiation of treatment, CT-guided percutaneous lung biopsy was performed, and a final diagnosis of primary pulmonary mucosa-associated lymphoid tissue lymphoma was made based on immunohistochemical examination. Primary lung MALT lymphoma remains a rare entity, with an indolent course and a reasonably favorable prognosis, whose diagnosis may be challenging.

    Full Text Available Plasmablastic lymphoma is a rare and aggressive lymphoma characterized by the diffuse proliferation of large neoplastic cells resembling immunoblasts with an immunophenotype of plasma cells. A 47-year-old male was referred to our hospital with gastrointestinal bleeding, and a mass 10 cm in diameter, was detected. An endoscopic biopsy was performed subsequently. Histopathological examination of the biopsy material revealed ulcer, alterations associated with ulcer, and further presented a diffuse infiltration of atypical cells with abundant cytoplasm and pleomorphic nuclei, some with crush artifacts in lamina propria. Immunohistochemically, the tumor cells were negative for cytokeratin, CD2, CD20, and PAX5; but they were positive for CD3, MUM1, CD38 and CD138. Ki67 proliferation index was as high as 95%. The case was signed out as CD3-positive plasmablastic lymphoma with clinical, histopathological and immunohisto-chemical findings. The plasmablastic lymphoma case with an aberrant CD3 expression has been presented here, which is rarely observed in stomach.

    Full Text Available Abstract Introduction Primary non-Hodgkin's lymphoma of the small and large bowel presenting as a perforated viscus entity with peritonitis is extremely rare. A thorough literature review did not reveal any cases where primary lymphoma of the jejunum presented with perforation and peritonitis synchronously with primary lymphoma of the descending colon. Case presentation This report concerns a 64-year-old Caucasian woman admitted with severe abdominal pain and fever. An emergency laparotomy revealed a large mass with perforation in the proximal jejunum with intense mesenteric thickening and lymphadenopathy. The descending colon was edematous and covered with fibrinous exudate. Histopathological examination of the resected segment of jejunum revealed a T cell non-Hodgkin's lymphoma. On post-operative day 10, a computed tomography scan of our patient's abdomen and pelvis showed leakage of contrast into the pelvis. Re-exploration revealed perforation of the descending colon. The histopathology of the resected colon also showed T cell non-Hodgkin's lymphoma. Her post-operative course was complicated by acute renal and respiratory failure. The patient died on post-operative day 21. Conclusions Lymphoma of the small intestine has been reported to have a poor prognosis. The synchronous occurrence of lesions in the small intestine or colon is unusual, and impacts the prognosis adversely. Early diagnosis and treatment are important to improve the prognosis of bowel perforation in patients with non-Hodgkin's lymphoma.

    Full Text Available Primary MALT lymphoma of the prostate is a rare disease which characteristically follows an indolent course. It is believed that infection or chronic inflammation may be triggers for malignant transformation in the prostate, but it is of unknown etiology. Reports of MALT lymphomas of the prostate with other concurrent primary prostate cancers are even more limited. We present the unique case of a 67 year old male with concurrent adenocarcinoma of the prostate and primary MALT lymphoma of the prostate. The patient was treated with standard therapy for prostate adenocarcinoma, which also sufficiently would treat a primary MALT lymphoma. He has been disease-free for over one year for both his primary malignancies. This case confirms that MALT lymphoma can arise concurrently with adenocarcinoma of the prostate.

    27 consecutive patients with malignant lymphomas were submittet to whole-body irradiations with doses of 0.5 to 3 Gy. Among these patients ten had been treated before. There were two complete and 16 partial remissions. The condition of five patients could not be considerably improved. Four patients showed a tumor progression during the time of bone marrow depression. The remission period was 11.5 (3 to 22 +) months. The hematologic side effects were considerable; in ten cases, the whole-body irradiation could not be continued because of a thrombocytopenia or an aplastic syndrome. A remarkable fact was the appearance of symptoms similar to that of lupus erythematodes in two patients. An inefficacy of whole-body irradiation did not exclude a response to subsequent chemotherapy. Our own experiences allow to make the following conclusion: in most of all patients with malignant lymphomas of low malignancy a measurable tumor reduction is achieved by whole-body irradiation. Because of the hematologic side effects a whole-body irradiation should be applied only in cases of malignant lymphomas of low malignancy the slow growth of which is proved by observation and which have not been treated before. The thrombocyte numbers should be above 100 000/..mu..l before therapy. Otherwise, the whole-body irradiation has to be stopped before the intended effective dose is reached because of an inevitably developing thrombocytopenia. A whole-body irradiation in case of a malignant lymphoma of low grade malignancy necessitates strict follow-up examinations conducted at regular intervals for a period of at least six weeks after the irradiation. The whole-body irradiation should never be applied as ultima ratio.

    Primary breast lymphoma is a rare type of non-Hodgkin lymphoma and usually affects women, although a few cases have been reported in men. Chemotherapy and radiation therapy, or a combination of both, are frequently administered for treatment of primary breast lymphoma, as local control by surgical resection is poor. No standard therapy has been established, and the optimal radiation dose and irradiation field for male patients are unknown. The present report describes a 75-year-old man with bilateral cirrhosis-induced gynecomastia who was diagnosed with primary breast lymphoma; specifically, diffuse large B-cell lymphoma. Because of his hepatic dysfunction, he was treated with radiation therapy alone. Radiation therapy was followed by eight cycles of rituximab monotherapy. Clinical response was good, with no signs of relapse. Clinicians may benefit from knowledge regarding effective treatment of primary breast lymphoma in male patients, which has been rarely reported owing to the low incidence of this condition. The outcome in the present case may help to establish effective treatment guidelines in similar cases.

    Background: Epstein-Barr virus plays an important role in pathogenesis of Hodgkin lymphoma. The first patient with Epstein-Barr positive Reed Sternberg cells was described in 1985. Since then association between Epstein-Barr virus and Hodgkin lymphoma has been shown in many parts of the world and its occurrence shows significant variation from continent to continent and from country to country. Method: The study was carried out at department of histopathology, Armed Forces Institute of Pathology from 27th April 2013 to 10th March 2014. A total of 55 cases of classical Hodgkin lymphoma were included in the study. Results: Out of 55 patients, 38 (69 percent) were male and 17 (31 percent) were female. The age of the patients ranged between 4-67 years with an average age of 29.4±21.72 years. Out of these, 44 cases (80 percent) were positive for latent membrane protein-1. Among positive cases 32 (72.72 percent) were male and 12 (27.28 percent) were female. Based upon histological subtypes MCHL was the commonest as a whole accounting for 87.3 percent as well as among both genders. Out of total 55 cases, 79.16 percent (38/48) of mixed cellularity Hodgkin lymphoma cases showed positivity for latent membrane protein-1 while 83.33 percent (5/6) cases of nodular sclerosis Hodgkin lymphoma and 100 percent (1/1) cases of lymphocyte depleted Hodgkin lymphoma showed positivity. No case of lymphocyte predominant classical Hodgkin lymphoma was diagnosed during the study. 80 percent of our classical Hodgkin lymphoma cases showed association with EBV expression. A total of 79.16 percent cases of mixed cellularity Hodgkin lymphoma showed LMP1 expression while 100 percent of lymphocyte depleted Hodgkin lymphoma showed LMP1 expression. Conclusion: The highest expression seen in lymphocyte depleted Hodgkin lymphoma subtype in contrast to mixed cellularity requires to be confirmed by a larger scale study comprising of substantial number of patients of lymphocyte depleted Hodgkin lymphoma

    Le lymphome de Burkitt (LB) est une forme de lymphome malin non-Hodgkinien qui provient de l'évolution maligne et de la prolifération de cellules lymphoïdes de type B. Le diagnostic positif repose sur la biopsie d'une masse tumorale ou la ponction de la moelle osseuse révélant la présence de cellules tumorales. Le cas rapporté est celui d'un jeune homme d'une vingtaine d'années qui a été adressé pour des tuméfactions gingivales évoluant depuis 1 mois suite à des extractions dentaires. L'examen anatomopathologique après biopsie complété par l'immunohistochimie conclut à un lymphome de Burkitt. La prise en charge a consisté en une chimiothérapie. Bien que rare, le lymphome de Burkitt est une tumeur agressive qui représente un véritable problème de santé publique d'où la place importante qu'occupe le médecin dentiste dans le diagnostic précoce afin de permettre une prise en charge rapide et appropriée seule garante de la guérison.

    Lymphoma (Hodgkin's and non-Hodgkin's) is a disease of the lymphatic system where the central neural system is affected in very rare cases. According to different authors the frequency of cases with lymphoma where the neural system is affected varies between 0, 2 % and 0, 5 %, and the primary cerebral lymphoma accounts for about 1-2% of ail brain neoplasms. The intracranial form of iymphoma is usually a late onset of the disease with serious and potentially fatal complications for the patient. These complications usually appear several years after diagnosing the disease, but the cerebral lymphoma may occur even in patients who are in remission which is the case with our patient. We present you a case with a 38 -year-old female, who was hospitalized in the Neuro ward with the following complaints -loss of speech for a few minutes, dizziness, weakness, tingling in her right leg as well as shuffling. This patient was diagnosed with histological B-cell non-Hodgkin's lymphoma 8 years ago. CT and MRI were carried out on that patient. Despite both clinical and radiographic suspicions for intracranial forms of lymphoma, the patient was still difficult to diagnose. A definitive diagnosis was given after a surgery and histological examination, i.e. non-Hodgkin's lymphoma - large B-cell lymphoma. This case is of interest because of its rare intracranial localization of the lymphoma. The knowledge of CT and MRI images of the intracranial form of lymphoma may help diagnosing, but images should be interpreted together with the clinical and paraclinical results Hodgkin's and non-Hodgkin's) is a disease of the lymphatic system where the central neural system is affected in very rare cases.

    In a 46-year-old female with a 1-month history of gait and speech disturbances, computed tomography (CT) demonstrated mass lesions of slightly high density in the left basal ganglia and left frontal lobe. The lesions were markedly enhanced by contrast medium. The patient received no specific treatment, but her clinical manifestations gradually abated and the lesions decreased in size. Five months after her initial examination, the lesions were absent on CT scans; only a small area of low density remained. Residual clinical symptoms included mild right hemiparesis and aphasia. After 14 months the patient again deteriorated, and a CT scan revealed mass lesions in the right frontal lobe and the pons. However, no enhancement was observed in the previously affected regions. A biopsy revealed malignant lymphoma. Despite treatment with steroids and radiation, the patient's clinical status progressively worsened and she died 27 months after initial presentation. Seven other cases of spontaneous regression of primary malignant lymphoma have been reported. In this case, the mechanism of the spontaneous regression was not clear, but changes in immunologic status may have been involved.

    Full Text Available Intestinal strongyloidiasis is a common disease in the world. In children, the worldwide prevalence rates ranged from 0.6% to 5.3% [1]. In Colombia studies report a prevalence of 1.3% in children, although it may be higher [2]. The most frequent symptoms are abdominal pain, diarrhea and weight loss. However, on rare occasions the infection can cause duodenal obstruction, pyloric hypertrophy and colonic mass. This article reports the first case of a toddler who presented with a mass in the cecum as a manifestation of Strongyloides stercolaris infection, which required surgical resection as it was initially believed to be a Burkitt lymphoma.

    Full Text Available In the oral cavity, extranodal non-Hodgkin's lymphoma can occur in the periapical region either in the maxilla or mandible. Also, it can mimic inflammatory lesions that arise around the teeth apices such as periapical granuloma, radicular cyst and osteomyelitis. Misdiagnosis of lymphomas in the jaws may reduce the chance of successful treatment and worsen the prognosis. Therefore, any growth of periapical tissue must be submitted for histopathological evaluation to avoid a delay in the diagnosis. We present a case of extranodal non-Hodgkin's lymphoma of a 53-year-old male in the right posterior mandible that was initially misdiagnosed as a reactive periapical lesion. This case illustrates the importance for both the pathologist and the clinician of considering malignant lesions such as lymphoma in the differential diagnosis of periapical radiolucency.

    Lymphoma is a malignant neoplasm of component cells of the lymphoid system which is very rare in the jaws. Here we report a case of primary diffuse large B-cell lymphoma located in the periapical region of a mandibular molar which was misdiagnosed as chronic periapical periodontitis. The present case was diagnosed at an early stage and effectively managed by chemotherapy. Although lymphoma of the mandible is rare, it must be considered in the differential diagnosis of radiolucent lesions in this region. Lack of knowledge of this rare presentation may lead to delays in diagnosis and poor prognosis. © 2013 Australian Dental Association.

    Clinical studies showed that advanced stage, high LDH, poor response to reduction therapy and combined bone marrow and central nervous system disease are significantly associated with a decreased event free survival (EFS) in pediatric mature B-NHL treated on FAB/LMB96. Although rearranged MYC/8q24 (R8q24) is characteristic of Burkitt Lymphoma (BL), little information is available on other cytogenetic abnormalities and their prognostic importance. We performed an international review of 238 abnormal karyotypes in childhood mature-B-NHL treated on FAB/LMB96: 76% BL, 8% Burkitt-like lymphoma, 13% diffuse large B-cell lymphoma (DLBCL). The main BL R8q24 associated chromosomal aberrations were +1q [29%], +7q and del(13q) [14% each]. The DLBCL appeared heterogeneous and more complex. Incidence of R8q24 [34%] was higher than reported in adult DLBCL. The prognostic value of cytogenetic abnormalities on EFS was studied by Cox model controlling for the known risk factors: R8q24, +7q and del(13q) were independently associated with a significant inferior EFS [HR: 6.1 (p=0.030), 2.5 (p=0.015), 4.0 (p=0.0003), respectively]. The adverse prognosis of R8q24 was observed only in DLBCL while del(13q) and +7q had a similar effect in DLBCL and BL. These results emphasize the significant biological heterogeneity and the development of cytogenetic risk adapted therapy in childhood mature-B-NHL. PMID:19020548

    Full Text Available Lymphoma-specific biomarkers contribute to therapeutic strategies and the study of tumorigenesis. Diffuse large B-cell lymphoma (DLBCL is the most common type of malignant lymphoma. However, only 50% of patients experience long-term survival after current treatment; therefore, developing novel therapeutic strategies is warranted. Comparative proteomic analysis of two DLBCL lines with a B-lymphoblastoid cell line (LCL showed differential expression of Ran GTPase-activating protein 1 (RanGAP1 between them, which was confirmed using immunoblotting. Immunostaining showed that the majority of DLBCLs (92%, 46/50 were RanGAP1(+, while reactive lymphoid hyperplasia (n = 12 was RanGAP1(+ predominantly in germinal centers. RanGAP1 was also highly expressed in other B-cell lymphomas (BCL, n = 180 with brisk mitotic activity (B-lymphoblastic lymphoma/leukemia: 93%, and Burkitt lymphoma: 95% or cell-cycle dysregulation (mantle cell lymphoma: 83%, and Hodgkin's lymphoma 91%. Interestingly, serum RanGAP1 level was higher in patients with high-grade BCL (1.71 ± 2.28 ng/mL, n = 62 than in low-grade BCL (0.75 ± 2.12 ng/mL, n = 52 and healthy controls (0.55 ± 1.58 ng/mL, n = 75 (high-grade BCL vs. low-grade BCL, p = 0.002; high-grade BCL vs. control, p < 0.001, Mann-Whitney U test. In vitro, RNA interference of RanGAP1 showed no effect on LCL but enhanced DLBCL cell death (41% vs. 60%; p = 0.035 and cell-cycle arrest (G0/G1: 39% vs. 49%, G2/M: 19.0% vs. 7.5%; p = 0.030 along with decreased expression of TPX2 and Aurora kinases, the central regulators of mitotic cell division. Furthermore, ON 01910.Na (Estybon, a multikinase inhibitor induced cell death, mitotic cell arrest, and hyperphosphorylation of RanGAP1 in DLBCL cell lines but no effects in normal B and T cells. Therefore, RanGAP1 is a promising marker and therapeutic target for aggressive B-cell lymphoma, especially DLBCL.

    Full Text Available BACKGROUND: Although multimodality treatment can induce high rate of remission in many subtypes of non-Hodgkin's lymphoma (NHL, significant proportions of patients relapse with incurable disease. The effect of human bone marrow (BM mesenchymal stem cells (MSC on tumor cell growth is controversial, and no specific information is available on the effect of BM-MSC on NHL. METHODOLOGY/PRINCIPAL FINDINGS: The effect of BM-MSC was analyzed in two in vivo models of disseminated non-Hodgkin's lymphomas with an indolent (EBV(- Burkitt-type BJAB, median survival = 46 days and an aggressive (EBV(+ B lymphoblastoid SKW6.4, median survival = 27 days behavior in nude-SCID mice. Intra-peritoneal (i.p. injection of MSC (4 days after i.p. injection of lymphoma cells significantly increased the overall survival at an optimal MSC:lymphoma ratio of 1:10 in both xenograft models (BJAB+MSC, median survival = 58.5 days; SKW6.4+MSC, median survival = 40 days. Upon MSC injection, i.p. tumor masses developed more slowly and, at the histopathological observation, exhibited a massive stromal infiltration coupled to extensive intra-tumor necrosis. In in vitro experiments, we found that: i MSC/lymphoma co-cultures modestly affected lymphoma cell survival and were characterized by increased release of pro-angiogenic cytokines with respect to the MSC, or lymphoma, cultures; ii MSC induce the migration of endothelial cells in transwell assays, but promoted endothelial cell apoptosis in direct MSC/endothelial cell co-cultures. CONCLUSIONS/SIGNIFICANCE: Our data demonstrate that BM-MSC exhibit anti-lymphoma activity in two distinct xenograft SCID mouse models of disseminated NHL.

    Anti-tumour necrosis factor (TNF) agents, through their intense immunoregulatory effect, have been suspected to increase the risk of malignant lymphoma. However, the classical epidemiological approaches conducted over about the last 10 years have not totally succeeded in addressing the question of a causal or artifactual association. Therefore, the analysis of a substantial set of case reports, although usually considered as poorly generalizable to the general population, could be particularly informative. Two main sources of case reports in postmarketing settings are available; publications in medical journals and reports to pharmacovigilance systems. The aim of the study was to compare the characteristics of case reports from both these sources in order to understand whether they provided the same information for the investigation of the causal link between lymphoma and anti-TNF agents. All case reports of malignant lymphoma in patients treated with an anti-TNF agent published in MEDLINE and all reports to the French pharmacovigilance system up to 1 February 2010 were identified. Cases of malignant lymphoma identified in postmarketing surveillance from both sources were compared regarding the following variables: age, sex, anti-TNF agent involved, indication for use, type of lymphoma, prior or concomitant immunosuppressive drugs and time to onset of lymphoma. A total of 81 published case reports and 61 cases reported to the French pharmacovigilance system were compared. In published reports, patients were younger (p = 0.03) and more frequently receiving a first anti-TNF treatment (p = 0.03), particularly infliximab (p = 0.03). Conversely, in the pharmacovigilance system reports, a succession of different anti-TNFs (p = 0.03) and adalimumab (p French pharmacovigilance system differed markedly for all characteristics tested, except sex and the use of prior or concomitant immunosuppressive drugs. Published case reports favoured convincing arguments

    2016-01-01

    Full Text Available Diffuse large B-cell lymphoma (DLBCL is a neoplasm of large B-lymphocytes with a diffuse growth pattern. The neoplastic cells express B-cell markers such as CD20 and PAX-5 and there may be coexpression of BCL-2, BCL-6, CD10, and MUM-1. With the exception of CD5, other T-cell markers are not commonly expressed in this neoplasm. Here, we describe the first reported case of a DLBCL with abnormal expression CD7 arising in a background of follicular lymphoma in an 81-year-old male who presented with a nontender left axillary mass. Additionally, no other T-cell antigens were expressed in this B-cell lymphoma. Expression of CD7 in DLBCL is exceptionally rare and its prognostic significance is unknown. Here, we describe this rare case with review of literature of known DLBCLs with expression of T-cell antigens.

    Full Text Available Abstract Introduction Pituitary adenomas represent the most frequently observed type of sellar masses; however, the presence of a rapidly growing sellar tumor, diabetes insipidus, ophthalmoplegia and headaches in an older patient strongly suggests metastasis to the pituitary. Since the anterior pituitary has a great reserve capacity, metastasis to the pituitary and pituitary involvement in lymphoma are usually asymptomatic. Whereas diabetes insipidus is the most frequent symptom, patients can present with headaches, ophthalmoplegia and bilateral hemianopsia. Case presentation A 70-year-old woman with no previous history of malignancy presented with headaches, right oculomotor nerve palsy and diabetes insipidus. As magnetic resonance imaging revealed a sellar mass involving the pituitary gland and infundibular stalk, which also extended into the right cavernous sinus and sphenoid sinus, the patient underwent an immediate transsphenoidal decompression surgery. Her prolactin was 102.4 ng/ml, whereas her gonadotropic hormone levels were low. A low level of urine osmolality after overnight water deprivation, along with normal plasma osmolality suggested diabetes insipidus. Histological examination revealed that the mass had been the infiltration of a high grade B-cell non-Hodgkin's lymphoma involving respiratory system epithelial cells. Paranasal sinus computed tomography scanning and magnetic resonance imaging of the thorax and abdomen were performed. Since magnetic resonance imaging did not reveal any abnormality, after paranasal sinus computed tomography was performed, we concluded that the primary lymphoma originated from the sphenoid sinus and infiltrated the pituitary. Chemotherapy and radiotherapy to the sellar area were planned, but the patient died and her family did not permit an autopsy. Conclusion Lymphoma infiltration to the pituitary is difficult to differentiate from pituitary adenoma, meningioma and other sellar lesions. To plan the

    Personal history of autoimmune diseases is consistently associated with increased risk of non-Hodgkin lymphoma. In contrast, there are limited data on risk of Hodgkin lymphoma following autoimmune diseases and almost no data addressing whether there is a familial association between the conditions. Using population-based linked registry data from Sweden and Denmark, 32 separate autoimmune and related conditions were identified from hospital diagnoses in 7476 case subjects with Hodgkin lymphoma, 18,573 matched control subjects, and more than 86,000 first-degree relatives of case and control subjects. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) as measures of relative risks for each condition using logistic regression and also applied multivariable hierarchical regression models. All P values are two-sided. We found statistically significantly increased risks of Hodgkin lymphoma associated with personal histories of several autoimmune conditions, including rheumatoid arthritis (OR = 2.7, 95% CI = 1.9 to 4.0), systemic lupus erythematosus (OR = 5.8, 95% CI = 2.2 to 15.1), sarcoidosis (OR = 14.1, 95% CI = 5.4 to 36.8), and immune thrombocytopenic purpura (OR = infinity, P = .002). A statistically significant increase in risk of Hodgkin lymphoma was associated with family histories of sarcoidosis (OR = 1.8, 95% CI = 1.01 to 3.1) and ulcerative colitis (OR = 1.6, 95% CI = 1.02 to 2.6). Personal or family history of certain autoimmune conditions was strongly associated with increased risk of Hodgkin lymphoma. The association between both personal and family histories of sarcoidosis and a statistically significantly increased risk of Hodgkin lymphoma suggests shared susceptibility for these conditions.

    Epstein-Barr Virus (EBV) is a γ-herpesvirus that infects >90% of the human population. Although EBV persists in its latent form in healthy carriers, the virus is also associated with several human cancers. EBV is strongly associated with Burkitt lymphoma (BL), even though there is still no satisfactory explanation of how EBV participates in BL pathogenesis. However, new insights into the interplay between viruses and microRNAs (miRNAs) have recently been proposed. In particular, it has been shown that B-cell differentiation in EBV-positive BL is impaired at the post-transcriptional level by altered expression of hsa-miR-127. Here, we show that the overexpression of hsa-miR-127 is due to the presence of the EBV-encoded nuclear antigen 1 (EBNA1) and give evidence of a novel mechanism of direct regulation of the human miRNA by this viral product. Finally, we show that the combinatorial expression of EBNA1 and hsa-miR-127 affects the expression of master B-cell regulators in human memory B cells, confirming the scenario previously observed in EBV-positive BL primary tumors and cell lines. A good understanding of these mechanisms will help to clarify the complex regulatory networks between host and pathogen, and favor the design of more specific treatments for EBV-associated malignancies

    To report a case of primary peripheral T-cell lymphoma of the penis. We analyzed the clinicopathological characteristics of the case of primary peripheral T-cell lymphoma using histological, cytochemical and immunohistochemical methods and by review of the literature. The patient was a 65 years old man and presented with a diffuse enlargement of the penis as the initial sign, followed by erosive ulcer in the caput penis and inguinal lymphadenectasis. The tumor was pathohistologically manifested as an epidermal ulcer, with tumorous necrosis around the capillary, infiltrative growth and atypical changes of the neoplastic cells and proliferation of capillaries. Immunohistochemically, the tumor cells were positive for CD43 and CD3, but negative for CD20, CD79a, CD34, CD30, CD56 and CD34. Clinically it responded to the chemotherapy designed for peripheral T-cell lymphoma. Primary peripheral T-cell lymphoma of the penis is an extremely rare malignant tumor, the diagnosis of which relies on histopathological examination, immunohistochemical staining and differentiation between squamous cell carcinoma and other types of lymphoma.

  5. The truncate mutation of Notch2 enhances cell proliferation through activating the NF-κB signal pathway in the diffuse large B-cell lymphomas.

    Directory of Open Access Journals (Sweden)

    Xinxia Zhang

    Full Text Available The Notch2 is a critical membrane receptor for B-cell functions, and also displays various biological roles in lymphoma pathogenesis. In this article, we reported that 3 of 69 (4.3% diffuse large B-cell lymphomas (DLBCLs exhibited a truncate NOTCH2 mutation at the nucleotide 7605 (G/A in the cDNA sequence, which led to partial deletion of the C-terminal of PEST (proline-, glutamic acid-, serine- and threonine-rich domain. The truncate Notch2 activated both the Notch2 and the NF-κB signals and promoted the proliferation of B-cell lymphoma cell lines, including DLBCL and Burkitt's lymphoma cell lines. Moreover, the ectopic proliferation was completely inhibited by ammonium pyrrolidinedithiocarbamate (PDTC, an NF-κB inhibitor. Simultaneously, PDTC also reduced the expression level of Notch2. Based on these results, we conclude that the Notch2 receptor with PEST domain truncation enhances cell proliferation which may be associated with the activation of the Notch2 and the NF-κB signaling. Our results are expected to provide a possible target for new DLBCL therapies by suppressing the Notch2 and the NF-κB signaling.

    Full Text Available Mycosis fungoides (MF is a malignant lymphoma, primarily of the skin and is characterized by infiltration of the skin by atypical T-cells which have a tendency for epidermotropism. Hodgkins disease (HD is considered to be a malignant lymphoma affecting predominantly the lymph nodes and characterized by presence of Reed- Sternberg cells on histopathology, though, the exact origin of the Reed Sternberg cell and the nature of the malignant cell is not known yet. Few cases of association of mycosis fungoides with Hodgkin′s lymphoma have been reported in the literature. It was reported in the past that when mycosis fungoides spreads to the lymph nodes and other viscera it frequently gets transformed into a more common lymphoma like Hodgkin′s lymphoma. However it has now been proved that the two malignancies are distinct and that such patients probably have a tumour diathesis.

    Full Text Available Primary central nervous system lymphoma (PCNSL is an infrequent form of non-Hodgkin lymphoma restricted to the CNS. More than 90% are type B and mainly affect patients aged 50-70 years. Immunodeficiency is the most important risk factor. The aim of our study was to evaluate the immune status, clinical presentation and findings in complementary studies of PCNSL patients. A retrospective analysis of 48 cases treated in our center between January 1992 and May 2015 was performed. Median age at diagnosis was 61 years (range 25-84; with male predominance (2.1:1. Forty one cases (85% were immunocompetent patients. Brain MRI findings showed parenchymal involvement in 45 cases (94%, 43% with frontal lobe and 35% basal ganglia, 4% had meningeal involvement and 2% had ophthalmic involvement at diagnosis. Fifty-five percent had restricted signal on diffusion weighted imaging and contrast enhancement was found in 89%. Pyramidal syndrome was the main initial clinical manifestation (56%. There were abnormal findings in 62% of CSF samples, but in only 11.1% positive cytology results were detected. The most frequent type was diffuse large B-cell lymphoma (83%, being B-cell type the most common form between them (96%. In our series PCNSL was more frequent in immunocompetent elderly male subjects. At initial evaluation, clinical manifestations and MRI findings were variable. The initial suspicion of this entity would allow an early diagnosis, avoiding empirical treatments that may confuse or delay diagnosis

    Diffuse large cell B-cell lymphoma of the skin is most commonly represented by diffuse large cell variants of primary cutaneous follicle center cell lymphoma and the leg-type lymphoma. In a minority of cases, the infiltrates are an expression of stage 4 disease of established extracutaneous B-cell lymphoma. We describe 3 patients with an aggressive form of B-cell lymphoma secondarily involving the skin. Two of the patients were in the ninth decade of life, whereas 1 patient was 34 years of age. In the elderly patients, there was an antecedent and/or concurrent history of follicular lymphoma, whereas in the younger patient, the tumor was a de novo presentation of this aggressive form of lymphoma. The elderly patients succumbed to their disease within less than a year from the time of diagnosis, whereas 1 patient is alive but with persistent and progressive disease despite chemotherapeutic intervention. The infiltrates in all 3 cases were diffuse and composed of large malignant hematopoietic cells that exhibited a round nucleus with a finely dispersed chromatin. Phenotypically, the tumor cells were Bcl-2 and CD10 positive, whereas Bcl-6 and Mum-1 showed variable positivity. One case showed combined Mum-1 positivity along with an acute lymphoblastic lymphoma phenotype, including the absence of CD20 expression. In each case, there was a c-MYC and BCL2/IGH rearrangement diagnostic of double-hit lymphoma. In one case, there was an additional BCL6 rearrangement, defining what is in essence triple-hit lymphoma. In conclusion, double-hit lymphoma is an aggressive form of B-cell neoplasia resistant to standard chemotherapy regimens, which in many but not all cases represents tumor progression in the setting of a lower grade B-cell malignancy.

    Full Text Available Background/Aim. Fine-needle aspiration biopsy is a quick, economical, and safe initial method in managing a patient with suspected lymphoma. According to a few reports on this preoblem, the aim of this study was to compare histological findings to cytomorphological ones in needle aspirates. We also compared these findings to the overal survival (OS time. Methods. We analyzed the fine-needle aspiration biopsies of peripheral lymph nodes, and the International Prognostic Index (IPI in 81 patients with non-Hodgkin’s lymphoma (NHL. We put these findings into correlation with OS time. Results. According to the International Working Formulation (IWF criteria, the dominant cell population was as follows: 18 patients had the small cell population, 21 patients had small cleaved cells, 18 patients had the mixed cell population, 21 patients had large cell population, 2 patients had Burkitt lymphoma type, and 1 patient had the dominant lymphoblasts. On presentation, 32 patients had a low IPI index, 32 patients had a low intermediate, and 17 patients had a high intermediate IPI. We confirmed the statistical significance (Kaplan-Mayer of cytomorphology (p = 0.013 and IPI index (p = 0.016 for survival time. During a 48-month follow-up, OS was 37.2 months for the patients with the dominant small cells, and 32 months for the patients with small cleaved cells (PH equivalent to indolent NHL. For the patients with the dominant mixed cell population, large cell population and Burkitt limphoma cell, OS were 17, 14.4, and 9.3 months, respectively (PH equivalent to aggressive NHL. Patients with low IPI had the highest OS, 36 months for the low intermediate and only 11.6 months for the high intermediate IPI index. Conclusion. We concluded that an initial cytological and clinical profile of patients with NHL, might give a quick and relevant information for planning an adequate therapy.

    We describe two cases of primary thyroid lymphoma, involving 64-and 74-year-old women who presented with a rapidly growing palpable mass in the anterior neck. In both patients, plain radiographs of this region revealed tracheal displacement and soft tissue mass, and CT scans demonstrated the presence of a large soft tissue mass with homogeneously low attenuation, predominantly located in the unilateral lobe of the thyroid gland. Within the masses there was no calcification, necrosis, or hemorrhage, though in one patient the trachea was involved posteriorly by the mass Both masses appeared as cold nodules on RI scan, and in both patients, the final diagnosis was diffuse large cell type non-Hodgkin's lymphoma with a background of Hashimoto's thyroiditis.

    Survival rates for children diagnosed with Burkitt lymphoma (BL) in Africa are far below those achieved in developed countries. Late stage of presentation contributes to poor prognosis, therefore this study investigated factors leading to delays in BL diagnosis and treatment of children in Uganda and western Kenya. Guardians of children diagnosed with BL were interviewed at the Jaramogi Oginga Odinga Teaching and Referral Hospital (JTRH) and Uganda Cancer Institute (UCI) from Jan-Dec 2010. Information on sociodemographics, knowledge, attitudes, illness perceptions, health-seeking behaviors and prior health encounters was collected using a standardized, pre-tested questionnaire. Eighty-two guardians were interviewed (20 JTRH, 62 UCI). Median "total delay" (1st symptoms to BL diagnosis) was 12.1 weeks [interquartile range (IQR) 4.9-19.9] in Kenya and 12.9 weeks (IQR 4.3-25.7) in Uganda. In Kenya, median "guardian delay" (1st symptoms to 1st health encounter) and "health system delay" (1st health encounter to BL diagnosis) were 9.0 weeks (IQR 3.6-15.7) and 2.0 weeks (IQR 1.6-5.8), respectively. Data on guardian and health system delay in Uganda were only available for those with system delay 2.6 weeks (range 0.1-16.0), and total delay 10.7 weeks (range 1.7-154.3). Guardians in Uganda reported more health encounters than those in Kenya (median 5, range 3-16 vs. median 3, range 2-6). Among Kenyan guardians, source of income was the only independent predictor of delay, whereas in Uganda, guardian delay was influenced by guardians' beliefs on the curability of cancer, health system delay, by guardians' perceptions of cancer as a contagious disease, and total delay, by the number of children in the household and guardians' role as caretaker. Qualitative findings suggest financial costs, transportation, and other household responsibilities were major barriers to care. Delays from symptom onset to BL treatment were considerable given the rapid growth rate of this

    2013-01-01

    Full Text Available Introduction. Sometimes it is not easy to clinically recognize subtle differences between intraocular lymphoma and noninfectious uveitis. The most common lymphoma subtype involving the eye is B-cell lymphoma. Case report. We presented two patients aged 59 and 58 years with infiltration of the subretinal space with a large B-cell non-Hodgkin intraocular lymphoma. The patients originally had clinically masked syndrome in the form of intermediate uveitis. As it was a corticosteroid-resistant uveitis, we focused on the possible diagnosis of neoplastic causes of this syndrome. During hospitalization, the neurological symptoms emerged and multiple subretinal changes accompanied by yellowish white patches of retinal pigment epithelium with signs of vitritis, which made us suspect the intraocular lymphoma. Endocranial magnetic resonance imaging established tumorous infiltration in the region of the left hemisphere of the cerebellum. The histopathological finding confirmed the diagnosis of large B-cell non-Hodgkin lymphoma of risk moderate degree, immunoblast - centroblast cytological type. The other patient had clinical chronic uveitis accompanied by yellowish shaped white echographic changes of the retina and localized changes in the level of the subretina. The diagnosis of lymphoma was made by brain biopsy. Conclusion. Uveitis masquerade syndrome should be considered in all patients over 40 years with idiopathic steroid-resistant uveitis. Treatment begun on time can affect the course and improve the prognosis of uveitis masquerade syndrome (UMS and systemic disease.

    Radiosensitivity, Thermosensitivity and their combined sensitivity on cell death were studied using mouse L5178Y, mouse FM3A and human Burkitt lymphoma. Eosin-staining method was tested for counting the heat-induced dead cells. The results obtained in the present study were as follows: (1) In irradiation with /sup 60/Co gamma-rays D/sub 0/ values of 1.3 Gy, 1.4 Gy and 1.7 Gy were obtained for Burkitt lymphoma, L5178Y and FM3A respectively. (2) By heating at 43degC, T/sub 0/ values of 4.1 min, 12.5 min and 32 min were obtained for L5178Y, FM3A and Burkitt lymphoma respectively. (3) Thermotolerance decay depended on cell doubling time, that is, the shorter the doubling time, the faster the decay. Furthermore, the cell line with the higher thermosensitivity showed a faster decay of thermotolerance for the three cell lines used in the present study. (4) The radiosensitizing effects were nearly the same in all three cell lines. (5) Using eosin-staining method, the cell survival curves after hyperthermia were ascertained and compared with those obtained by colony forming method. In L5178Y the survival curves obtained by the two methods were nearly the same. In FM3A only some correlation was found betweewn the cell survival curves obtained by the two methods but in Burkitt lymphoma no correlation was found. (author) 52 refs.

    Retrospective and prospective cohort studies suggest that central nervous system involvement occurs in approximately 0.5 % of patients with advanced Hodgkin's lymphoma. The isolated primary intracranial manifestation of Hodgkin's lymphoma is an extremely rare finding, with few cases reported in the literature. Little is known about the optimal treatment and prognosis of these tumors. Here, we present a case report with a review of the literature. A 47-year-old Caucasian man with persistent frontal headache and unspecific vertigo for half a month was diagnosed with nodular space-occupying lesions in the cerebellum. His medical history included multiple sclerosis, which was treated for 20 years with the immunosuppressive drug azathioprine. Further staging revealed no additional lesions suspected of being malignant. The patient underwent total tumor resection. Immunohistopathological examination showed Epstein-Barr virus-associated classic Hodgkin's lymphoma. Diagnostic bone marrow punction excluded lymphoma involvement of the bone marrow. The patient had no B symptoms. Consequently, the patient was classified as having stage I E A disease according to the Modified Ann Arbor Classification of Hodgkin Lymphoma and received systemic chemotherapy followed by radiation therapy for the former cerebellar tumor region. He was in complete clinical remission at the last follow-up 9 months after the initial diagnosis. This case report and literature review suggest that multimodal treatment leads to a remarkable clinical outcome in Hodgkin's lymphoma with intracranial involvement. (orig.) [de

    Lymphomas represent the fifth most frequent cancer in Lebanon. However, little is known concerning epidemiologic characteristics and distribution of lymphoid neoplasms according to the 2008 WHO classification. We conducted a retrospective study of lymphoma cases diagnosed from 2008 till 2012 at Hotel-Dieu de France University Hospital. A total of 502 new cases of lymphoma were diagnosed at our institution during a five year period: 119 cases (24%) were Hodgkin lymphomas (HL) and 383 cases (76%) were non-Hodgkin lymphomas (NHL). HLs were equally distributed in both sexes with a mean age at diagnosis of 30 years. Among NHL, 87% (332 cases) were B cell lymphomas, 9% (34 cases) were T cell lymphomas and 4%(17 cases) were classified as precursor lymphoid neoplasms. Among B cell lymphomas, 44% (147 cases) were diffuse large B cell lymphomas (DLBCL), 20% (65 cases) follicular lymphomas and 8% (27 cases) mantle cell lymphomas. DLBCL were equally distributed in both sexes with a mean age of 58 years. Follicular lymphomas were characterized by a male predominance (57%) and a mean age of 60 years. Mantle cell lymphomas showed a pronounced male predominance (85%) with a mean age of 60 years in men and 70 years in women. Some 72% of patients having T cell lymphomas were men, with a mean age of 57 years in men and 45 years in women, while 65% of patients having precursor lymphoid neoplasms were women with a mean age of 22 years in women and 30 years in men. The lymphoma subtype distribution in Lebanon is unique when compared to other countries from around the world. In fact, Hodgkin and follicular lymphomas are more frequent than in most Far Eastern, European and American countries, while T-cell lymphomas and DLBCL are less frequent.

    Full Text Available Lactic acidosis is commonly observed in clinical situations such as shock and sepsis, as a result of tissue hypoperfusion and hypoxia. Lymphoma and leukemia are among other clinical situations where lactic acidosis has been reported. We present a case of a 59-year-old female with lactic acidosis who was found to have aggressive B-cell lymphoma. There have been 29 cases of lymphoma induced lactic acidosis reported thus far; however all reported cases have abnormal vital signs or concomitant medical conditions that may lead to lactic acidosis. The pathogenesis of malignancy-induced lactic acidosis is not well understood; however associated factors include increased glycolysis, increased lactate production by cancer cells, and decreased hepatic clearance of lactate. When it occurs, lactic acidosis is a poor prognostic sign in these patients. Prompt diagnosis and treatment of underlying lymphoma or leukemia remains the only way to achieve complete resolution of lactic acidosis in these patients.

    Full Text Available We report three elderly patients with follicular lymphoma in situ (FLIS each highlighting a unique pattern of disease presentation and progression. The first patient had incidentally detected FLIS with peripheral blood spill and yet had an 11-year uneventful follow up. The second patient with an overt follicular lymphoma (FL developed high-grade transformation in jejunum with FLIS extensively involving the Payers patches. The third patient had a FLIS but that qualified as higher grade and was treated in spite of lack of overt FL mainly because of higher grade and patient subsequently did develop overt FL. The first case of typical FLIS confirms that peripheral blood spill does not connote poor prognosis in FLIS, the second case illustrates that FLIS may colonize mucosa-associated lymphoid tissue as part of homing in process of a disseminated FL and the third case validates the aggressive nature of high-grade FLIS.

    Full Text Available Primary cutaneous CD4-positive small- to medium-sized pleomorphic T-cell lymphoma is a provisional entity in the 2005 WHO-EORTC classification for cutaneous lymphomas. It is a rare condition and, in most cases, it has a favorable clinical course and prognosis. Primary cutaneous CD4-positive small/medium pleomorphic T-cell lymphoma (PCSM-TCL is defined as a cutaneous T-cell lymphoma with predominantly small- to medium-sized CD4-positive pleomorphic T-cells without a history of patches and plaques typical of mycosis fungoides. PCSM-TCL usually presents as a solitary plaque or tumor on the head, neck, trunk or upper extremities and it is considered to have indolent clinical behavior. Histologically, it is characterized by a dense infiltration of small/medium-sized pleomorphic T-cells that involves the entire dermal thickness, often with nodular extension into the hypodermis. Using immunohistochemical staining, the majority of the reported cases proved to be CD3, CD4 positive and CD8, CD30 negative. However, due to the rarity and heterogeneity of the PCSM-TCL, precise clinicopathologic characteristics of PCSM-TCL have not been well characterized and the optimal treatment for this group of lymphomas is yet to be defined. Dermatologists and pathologists should be aware of this entity in order to avoid unnecessary aggressive treatments.

    which are active as 'naked' antibodies are required to eradicate larger tumour burdens and to cure animals. For anti-idiotype antibodies the antibody and irradiation were shown to have an additive effect in vitro and in vivo in increasing the amount of tumour apoptosis. This increased therapeutic efficacy translated into animals with large tumour burdens being cured. These results strongly imply that RIT is much more than targeted irradiation and suggest potential mechanisms for the successes in the clinic. During the course of this work a new in vivo and in vitro variant of the BCL 1 tumour was isolated II-BCL 1 . In contrast to the BCL 1 tumour this variant establishes as a syngeneic nodular lymphoma in vivo and grows in free suspension in vitro. This tumour model has provided a useful tool to investigate the induction of apoptosis both in vitro and in vivo. Finally apoptosis induced by irradiation and antibody were investigated in murine and human lymphoma cells in vitro. The murine radiosensitive B- and T-cell lymphomas were demonstrated to induce large amounts of early apoptosis within 24 hours. In contrast p53 mutant Burkitt's Lymphoma cell lines were resistant to irradiation and responded with delayed apoptosis reaching peak amounts at day 6. For these p53 mutated cells, DNA synthesis and mitosis are uncoupled after irradiation and these cells form increasingly large polyploid 'giant cells'. These giant cells undergo complex apoptosis and also appear to give rise to mitotically competent survivors. Thus giant cells appear to be part of a repair process and apoptosis to act not only in the death process but also in the selection of life. (author)

    ONC201, founding member of the imipridone class of small molecules, is currently being evaluated in advancer cancer clinical trials. We explored single agent and combinatorial efficacy of ONC201 in preclinical models of hematological malignancies. ONC201 demonstrated (GI50 1-8 µM) dose- and time-dependent efficacy in acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CML), chronic lymphocytic leukemia (CLL), diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL), Burkitt's lymphoma, anaplastic large cell lymphoma (ALCL), cutaneous T-cell lymphoma (CTCL), Hodgkin's lymphoma (nodular sclerosis) and multiple myeloma (MM) cell lines including cells resistant to standard of care (dexamethasone in MM) and primary samples. ONC201 induced caspase-dependent apoptosis that involved activation of the integrated stress response (ATF4/CHOP) pathway, inhibition of Akt phosphorylation, Foxo3a activation, downregulation of cyclin D1, IAP and Bcl-2 family members. ONC201 synergistically reduced cell viability in combination with cytarabine and 5-azacytidine in AML cells. ONC201 combined with cytarabine in a Burkitt's lymphoma xenograft model induced tumor growth inhibition that was superior to either agent alone. ONC201 synergistically combined with bortezomib in MM, MCL and ALCL cells and with ixazomib or dexamethasone in MM cells. ONC201 combined with bortezomib in a Burkitt's lymphoma xenograft model reduced tumor cell density and improved CHOP induction compared to either agent alone. These results serve as a rationale for ONC201 single-agent trials in relapsed/refractory acute leukemia, non-Hodgkin's lymphoma, MM and combination trial with dexamethasone in MM, provide pharmacodynamic biomarkers and identify further synergistic combinatorial regimens that can be explored in the clinic.

    Full Text Available Hepatobiliary involvement by malignant lymphoma is usually a secondary manifestation of systemic disease, whereas primary non-Hodgkin's lymphoma of the extrahepatic biliary ducts is an extremely rare entity. We describe the case of a 57-year-old man who presented with an acute onset of obstructive jaundice and severe itching. Abdominal ultrasonography and computed tomography revealed intrahepatic and common hepatic ducts dilatation. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography showed a mid-common bile duct stricture. The patient was presumed to have cholangiocarcinoma of the common bile duct, and an en bloc resection of the tumor with Roux-en-Y hepaticojejunostomy and porta-hepatis lymph nodes dissection was performed. Histopathology and immunohistochemistry revealed a large B cell non-Hodgkin's lymphoma. The patient received six cycles of combination chemotherapy using cyclophosphamide, vincristine, prednisone, and rituximab (CVP-R protocol, and after a 5-year follow-up he is still in complete remission. We also reviewed the cases published from 1982 to 2012, highlighting the challenges in reaching a correct preoperative diagnosis and the treatment modalities used in each case.

    Increased use of serial EBV-PCR monitoring after pediatric transplantation has led to the identification of asymptomatic patients who carry very high viral loads over prolonged periods. The significance of this high-load state is unknown. We speculated that this state may identify patients at high risk for development of late PTLD/lymphoma. We reviewed data on 71 pediatric heart recipients who had serial viral load monitoring since 1997. Chronic high-load state was defined as the presence of >16,000 genome copies/mL whole blood on > or =50% of samples over at least 6 months. Among 20 high-load carriers (eight following prior PTLD, seven with prior symptomatic EBV infection, five without previous EBV disease), 9 (45%) developed late-onset PTLD 2.5-8.4 years posttransplant (including with four Burkitt's lymphoma). Among 51 controls with low (n = 39) or absent (n = 12) loads, only 2 (4%; p < 0.001 absent/low vs. high load) developed late PTLD/lymphoma. By multivariable analysis, high-load carrier state (OR = 12.4, 95% CI 2.1-74.4) and prior history of PTLD (OR = 10.7, 95% CI 1.9-60.6) independently predicted late PTLD. A chronic high EBV-load state is not benign and is a predictor of de novo or recurrent PTLD.

    Full Text Available Abstract Introduction Primary hepatic lymphoma is an unusual form of non-Hodgkin's lymphoma that usually presents with constitutional symptoms, hepatomegaly and signs of cholestatic jaundice. Diffuse hepatic infiltration is uncommon and presentation with acute hepatic failure even more rare. The presence of markedly elevated ferritin levels can complicate the evaluation process and suggest alternative diagnoses. We present the case of a middle-aged woman exhibiting pancytopenia, hyperferritinemia and rapidly deteriorating to develop acute hepatic failure. Her initial clinical picture led to a working diagnosis of adult onset Still's disease with probable hemophagocytic syndrome before her worsening liver function necessitated a percutaneous liver biopsy and establishment of the final diagnosis of primary hepatic lymphoma. Conclusion Primary hepatic lymphoma is an uncommon malignancy and its manifestation as progressive hepatitis or acute fulminant hepatic failure can be difficult to diagnose. The presence of constitutional symptoms, pancytopenia and high ferritin levels can complicate the evaluation process. A liver biopsy early in the course of liver dysfunction may establish the diagnosis without a higher risk of bleeding complications seen once liver failure sets in.

    Full Text Available Primary non-Hodgkin’s lymphoma (NHL of the breast constitutes 0.04%-0.53% of all malignancies and 2.2% of extra nodal lymphomas. In total, 7%-8% of all B-cell lymphomas are the mucosa-associated lymphoid tissue (MALT type, of which up to 50% of primary gastric MALT lymphoma. Herein we present a patient with breast MALT lymphoma that transformed to diffuse large B-cell lymphoma (DLBCL. A 69-year-old female presented with a mass on her left breast. Physical examination showed a 3 × 3-cm mass located 1 cm from the areola on the upper lateral quadrant of the breast at the 1 o’clock position, which was fixed and firm. Excisional biopsy was performed and pathologic examination of the specimen showed MALT lymphoma transformation to DLBCL. The patient was staged as II-EA. The rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP protocol was scheduled as treatment. Following 6 courses of R-CHOP, 2 additional courses of rituximab were administered. Positron emission tomography (PET-CT was done at the end of the treatment. PET showed that the patient was in complete remission. At the time this report was written, the patient was being followed-up at the outpatient clinic on a regular basis. Lymphoma of the breast is a rarity among malignant tumors of the breast. The most common type of lymphoma is DLBCL. Breast MALT lymphoma is extremely rare. Primary MALT lymphoma of the breast can transform from low grade to high grade and recurrence is possible; therefore, such patients should be monitored carefully for transformation.

    2018-01-01

    Full Text Available Intravascular large B-cell lymphoma is a rare subtype of extranodal diffuse B-cell lymphoma characterized by proliferation of neoplastic cells within the lumen of small and medium sized vessels. Clinical and imaging findings are nebulous as the intravascular subtype of lymphoma can involve a multitude of organs. Involvement of the gallbladder is extremely uncommon, and imaging findings can be easily confused for more prevalent pathologies. We report a case of intravascular large B-cell lymphoma in an 83-year-old male and review clinical presentation and imaging findings on CT, ultrasound, hepatobiliary iminodiacetic acid (HIDA scan, and MRI. It is important for the radiologist to know about this disease as the imaging findings are atypical of other types of lymphoma, and this may lead to a delay in diagnosis and treatment.

    Full Text Available Non-Hodgkin's lymphomas (NHLs embody a diverse group of malignancies that originate from the lymphoid system. NHL often exhibit in an extranodal pattern, pertaining to the head and neck region. Intraoral sites are much less frequent, accounting for approximately 3.5% of all oral malignancies. Although the exact cause of NHL still remains inconspicuous, however, research has focused on some factors that may contribute to the development of lymphoma, including genetic factors, impaired immune system and viruses, such as HIV or EBV. Clinically, the bony lesion may present as localized or diffuse swelling, with low-grade pain, sweating, unexplained weight loss, fever, etc. Radiographically, these lesions resemble osteomyelitis or other malignancies creating a diagnostic dilemma. Microscopically, diffused lymphomas consist of large tumor cells with large nuclei that are more than twice the size of lymphocytes which may either exhibit centroblastic or immunoblastic features. Here, we report a rare case of NHL affecting the jaws of a 60-year-old male patient.

    Herein, we describe our experience in treating a case of primary pulmonary mucosa-associated lymphoid tissue lymphoma detected as a nodular opacity. A 79-year-old man was referred to our hospital. Computed tomography showed a nodular opacity measuring 20 mm in diameter with regular margins in segment 5 of the right middle lobe of the lung. Although the bronchoscopic brush cytology result was class III, the patient was tentatively diagnosed with suspected mucosa-associated lymphoid tissue lymphoma. A thoracoscopic right middle lobectomy was performed. The pathological findings showed nodular proliferation of small to medium-sized, mature-appearing atypical lymphoid cells, lymphoepithelial lesions, and vague follicles suggesting follicular colonization in some areas. The patient was diagnosed with low-grade small B-cell lymphoma and mucosa-associated lymphoid tissue lymphoma. He has remained well to date, 23 months after surgery, without evidence of recurrence.

    Full text: Lymphoma (Hodgkin's and non-Hodgkin's) is a disease of the lymphatic system where the central neural system is affected in very rare cases. According to different authors the frequency of cases with lymphoma where the neural system is affected varies between 0.2% and 0.5%, and the primary cerebral lymphoma accounts for about 1-2% of all brain neoplasms. The intracranial form of lymphoma is usually a late onset of the disease with serious and potentially fatal complications for the patient. These complications usually appear several years after diagnosing the disease, but the cerebral lymphoma may occur even in patients who are in remission, which is actually the case with our patients. We present you two cases - a 38-year-old female and a 48-year-old male, who were hospitalized in Neuro ward with the following complaints: loss of speech for a few minutes, dizziness, weakness, tingling and shuffling of one of the legs. Those patients were diagnosed with histological B-cell non-Hodgkin's lymphoma and Hodgkin's lymphoma, several years ago. CT and MRI were carried out on the patients. Despite both clinical and radiographic suspicions for intracranial forms of lymphoma, the patients were still difficult to diagnose. A definitive diagnosis was given after a surgery and histological examination, i.e. non- Hodgkin's lymphoma - large B-cell lymphomas, and Hodgkin's lymphoma. These cases are of interest because of their rare intracranial localization of the lymphoma. The knowledge of CT and MRI images with the intracranial form of lymphoma may help diagnosing, but images should be interpreted together with the clinical and paraclinical results

    Full Text Available Breast cancer in men is uncommon, and even more rare is the simultaneous presentation of two different malignancies. A 39-year-old man was diagnosed with both breast cancer and axillary lymphoma. Familiar history revealed that his mother died because of breast cancer. The patient underwent fine needle aspiration leading to the diagnosis of malignant lesion. Modified radical mastectomy was performed. Histology revealed an infiltrating ductal carcinoma 2.8 cm wide, grade 2, with vascular and lymphatic invasion. Surprisingly, one of the second level nodes was confirmed as a high-grade large B cell non-Hodgkin's lymphoma. No family inheritance or gene mutations (BRCA 1 and 2 were found. The patient underwent local radiotherapy, followed by 6 chemotherapy courses (RCHOP and treatment with tamoxifen 20 mg/daily. To our knowledge, this is the first case reported in literature of male breast cancer and axillary lymphoma simultaneously confirmed in the same patient.

    A 49-year-old woman, who complained of sore throat and swelling of bilateral tonsils, was pathologically diagnosed Lennert's lymphoma by biopsy of tonsils. She was treated by radiation with combined chemotherapy. She was restored to complete remission and still alive now. Lennert's lymphoma which was histologically characterized by a high content of epithelioid histocytes was first reported by Lennert and Mestdagh in 1968. Since then, some cases have been reported. But it's clinical entity is still a controversial entity, difficult to classify. Some consider it as a distinct entity, the others as a variant of the disease which have been already established.

Histopathological examination revealed extensive involvement and replacement of testicular parenchyma by a tumor composed of large discohesive sheets of cells with pleomorphic, hyperchromatic nuclei and prominent nucleoli. Immunohistochemical (IHC staining showed reactivity for LCA & Pan B (CD20 and negativity for OCT 3/4, SALL4 and Inhibin. Moreover, Pan T (CD3 highlighted reactive T-cells. These features rendered the diagnosis of DLBCL of testis. The hybrid 2-[fluorine-18] fluoro-2-deoxy-d-glucose (FDG positron emission tomography/computed tomography (PET/CT demonstrated two para-aortic FDG avid lymph nodes on the left side at the level of L2 vertebra. Presently, the patient has been planned for doxorubicin-based chemotherapy (i.e., cyclophosphamide, doxorubicin, vincristine and prednisone; CHOP along with intrathecal Methroxate (MTX, which would presumably improve the prognosis. Our study would expand the pool of this uncommon tumor towards its better understanding.

    Full text: Mucosa associated lymphoid tissue (MALT lymphoma) of the urinary bladder is a rare condition. The best treatment approach for this disease is controversial. A case report on a patient with MALT lymphoma of the urinary bladder. The relevant current literature was reviewed. A 79 year old lady presented with haematuria in 2002. Ultrasound of the pelvis showed a large tumour in the bladder. Cystoscopy revealed a mass arising from the bladder. Transurethral resection of the tumour was performed. Histology showed Non Hodgkin's lymphoma of MALT type. CT showed a 8.9 X 7.6 cm solid tumour involving almost whole of the bladder. The patient could not tolerate anti helicobacter treatment and was then treated with radiotherapy. The pelvis was treated with 18 MV photons with a 3 field technique in 2 phases, with CT planning. In phase 1, the pelvis was treated to 24 Gy in 12 fractions, over 2.5 weeks. Phase 2 was treated to a reduced pelvic field, to a dose of 16 Gy in 8 fractions over 1.5 weeks. Five months after radiotherapy, repeat cystoscopy and biopsy of bladder base showed no evidence of malignancy. MALT lymphoma of the urinary bladder responds well to radiotherapy and permits bladder preservation. The current literature in management of MALT lymphoma of urinary bladder is reviewed

    Full Text Available Primary mediastinal B-cell lymphoma (PMBCL is an uncommon aggressive subset of diffuse large B-cell lymphomas. Although PMBCL frequently spreads locally from the thymus into the pleura or pericardium, it rarely invades directly through the heart. Herein, we report a case of a young Mexican female diagnosed with PMBCL with clear infiltration of lymphoma through the cardiac wall and into the right atrium and tricuspid valve leading to tricuspid regurgitation. This was demonstrated by cardiac MRI and transthoracic echocardiogram. In addition, cardiac MRI and CT scan of the chest revealed the large mediastinal mass completely surrounding and eroding into the superior vena cava (SVC wall causing a collar of stokes. The cardiac and SVC infiltration created a significant therapeutic challenge as lymphomas are very responsive to chemotherapy, and treatment could potentially lead to vascular wall rupture and hemorrhage. Despite the lack of conclusive data on chemotherapy-induced hemodynamic compromise in such scenarios, her progressive severe SVC syndrome and respiratory distress necessitated urgent intervention. In addition to the unique presentation of this rare lymphoma, our case report highlights the safety of R-CHOP treatment.

    To report the clinicopathologic features of monotypic immunoglobulin G4+ (IgG4+) lymphoid and plasmacytic proliferations. Cases were identified from the pathology files. Pathology and clinical materials were reviewed. Eleven cases of monotypic IgG4+ proliferations were identified at nodal, orbital, or salivary sites. Six cases (three men, three women; age, 57-94 years) met criteria for lymphoma or plasma cell neoplasia. Most contained frequent Mott cells. Five cases (three men, two women; age, 40-80 years) had restricted proliferations of atypical/monotypic IgG4+ plasma cells in a background of reactive lymphoid hyperplasia or inflammation. Monotypic IgG4+ proliferations include lymphomas, plasmacytic neoplasms, and a previously uncharacterized group of proliferations not meeting criteria for conventional hematolymphoid neoplasia. Distinct features included prominent Mott cells and/or monotypic plasma cells within follicles. The proliferations were infrequently associated with IgG4-related disease (IgG4-RD). Our findings raise questions regarding the relationship between clonal IgG4+ proliferations, reactive/inflammatory processes, and IgG4-RD. © American Society for Clinical Pathology, 2017.

    T-cell lymphoblastic lymphoma is a highly aggressive tumor derived from lymphocyte of the thymus, which accounts for 2% of non-Hodgkin's lymphoma. The disease occurs most commonly in adolescent and young adult males. It often results in respiratory emergency because of high proliferation rate. In this case, we confirmed the rapid progression of T-cell lymphoblastic lymphoma through the chest CT scan with one week interval. Three days of empirical chemotherapy resulted in substantial reduction of mediastinal mass, pleural thickening and pleural effusion.

    Full Text Available Since nasal NK/T cell lymphoma and NK/T cell lymphoma nasal type are rare diseases, gastric involvement has seldom been seen. We report a unique case of a patient with a primary NK/T cell lymphoma nasal type of the stomach with skin involvement. The patient had no history of malignant diseases and was diagnosed with hematemesis and intense bleeding from his gastric primary site. Shortly after this event, exanthemic skin lesions appeared with concordant histology to the primary site. Despite chemotherapy, the patient died one month after the first symptomatic appearance of disease.

    2014-01-01

    Full Text Available Background. Lymphoma of the urinary bladder (LUB is rare. Aims. To review the literature on LUB. Methods. Various internet databases were used. Results. LUB can be either primary or secondary. The tumour has female predominance; most cases occur in middle-age women. Secondary LUB occurs in 10% to 25% of leukemias/lymphomas and in advanced-stage systemic lymphoma. Less than 100 cases have been reported. MALT typically affects adults older than 60 years; 75% are female. Diffuse large B-cell lymphoma is also common and may arise from transformation of MALT. LUB presents with haematuria, dysuria, urinary frequency, nocturia, and abdominal or back pain. Macroscopic examination of LUBs show large discrete tumours centred in the dome or lateral walls of the bladder. Positive staining of LUB varies by the subtype of lymphoma; B-cell lymphomas are CD20 positive. MALT lymphoma is positively stained for CD20, CD19, and FMC7 and negatively stained for CD5, CD10, and CD11c. LUB stains negatively with Pan-keratin, vimentin, CK20, and CK7. MALT lymphoma exhibits t(11; 18(q21: 21. Radiotherapy is an effective treatment for the MALT type of LUB with no recurrence. Conclusions. LUB is diagnosed by its characteristic morphology and immunohistochemical characteristics. Radiotherapy is a useful treatment.

    There is a need to study potential infective etiologies in lymphomas. Lymphocyte-transforming viruses can directly infect lymphocytes, disrupt normal cell functions, and promote cell division. Epstein-Barr virus (EBV) is known to be associated with several lymphomas, especially Hodgkin lymphomas (HLs). And recently, the lymphocyte-transforming role of hepatitis B virus (HBV) has been emphasized. The aim of this study was to elucidate the association of two potentially oncogenic, widely prevalent latent DNA viruses, EBV and HBV, in non-HL (NHL). In this prospective study, we estimated plasma EBV and HBV DNA in NHL patients. Peripheral blood was obtained from newly diagnosed, treatment na ïve, histologically confirmed NHL patients. Plasma EBV DNA was quantified by real-time polymerase chain reaction (PCR) targeting Epstein-Barr Nucleic acid 1 while the plasma HBV DNA was detected using nested PCR targeting HBX gene. In a small subset of patients, follow-up plasma samples post-anticancer chemotherapy were available and retested for viral DNA. Of the 110 NHL patients, ~79% were B-cell NHL and ~21% were T-cell NHL. Plasma EBV-DNA was detected in 10% NHLs with a higher EBV association in Burkitt lymphoma (33.3%) than other subtypes. Pretherapy HBV DNA was detected in 21% NHLs; most of them being diffuse large B-cell lymphoma (DLBCL). Moreover, 42% of DLBCL patients had HBV DNA in plasma. Since all patients were HBV surface antigen seronegative at diagnosis, baseline plasma HBV-DNAemia before chemotherapy was indicative of occult hepatitis B infection. Our findings indicate a significant association of HBV with newly diagnosed DLBCL.

    Primary Breast lymphoma is a rare lesion that has been reported in patients without HIV. However, Primary Breast lymphoma occurring in a patient with HIV has rarely been reported despite the fact that HIV infection is known to increase the propensity to develop certain types of lymphoma. We report a case of an HIV patient with breast lymphoma that was discovered by screening mammography while presenting our argument for more cautionary management in this patient population.

  16. Primary Hepatosplenic Large B-Cell Lymphoma

    2008-03-01

    Full Text Available Diffuse large B-cell lymphoma is the most common form of lymphoma. It usually begins in the lymph nodes; up to 40% may have an extranodal presentation. According to a definition of primary extranodal lymphoma with presentation only in extranodal sites, there are reports of large B-cell lymphomas limited to liver or spleen as separate entities, and to date there have been only three documented cases of primary hepatosplenic presentation. This paper reports a fourth case. Due to a review of the literature and the clinical course of the case reported, we conclude that primary hepatosplenic large B-cell lymphoma has been found predominantly in females older than 60 years. The patients reported had <2 months of evolution prior to diagnosis, prominent B symptoms, splenomegaly in three and hepatomegaly in two, none with lymph node involvement. All had thrombocytopenia and abnormal liver function tests; three had anemia and elevated serum lactic dehydrogenase levels, two with hemophagocytosis in bone marrow. Because of the previously mentioned data, it can be stated that primary hepatosplenic lymphoma is an uncommon and aggressive form of disease that requires immediate recognition and treatment.

    2016-11-01

    Full Text Available Lymphoma is a lymphoid tumor that originates in hematopoietic organs such as lymph node, spleen or liver. In dogs, the overall prevalence of cardiac tumors was estimated to be only 0.19% based on the results of the survey of a large database, and lymphomas accounts for approximately 2% of all cardiac tumors. In general, the involvement of the myocardium is rarely described in canine lymphoma. Currently, there is no evidence of a viral association with primary cardiac lymphoma in dogs, but other types of immunosuppression may contribute to abnormal events, such as involvement primary cardiac. The aim of this study was to analyze a case of sudden death of a bitch, SRD, aged 10, who had the final diagnosis of cardiac lymphoma.

    Primary effusion lymphoma, a human herpesvirus 8 (HHV8)-associated lymphoma, is uncommon, and it is usually seen in human immunodeficiency virus (HIV)-infected patients. It presents as a body cavity-based lymphomatous effusion, but several cases of the so-called solid primary effusion lymphoma presenting as solid tumors without associated lymphomatous effusion have been reported. They have similar clinical, histopathological and immunophenotypical features. Most of them have a B-cell genotype. This suggests the solid variant may represent a clinicopathological spectrum of primary effusion lymphoma. We report a case of HHV8-associated lymphoma histopathologically and immunophenotypically mimicking cutaneous anaplastic large cell lymphoma. The patient was a 31-year-old HIV-seropositive man presenting with skin nodules over his right thigh. Biopsy of the nodules showed anaplastic large cells infiltrating the dermis. These malignant cells strongly expressed CD3, CD30 and CD43. Cutaneous anaplastic large T-cell lymphoma was initially diagnosed, but further tests, including immunoreactivity for HHV8 protein and clonal rearrangements of immunoglobulin genes, confirmed the diagnosis of HHV8-associated B-cell lymphoma with aberrant T-cell marker expression. This case provides an example of solid primary effusion lymphoma mimicking cutaneous anaplastic large T-cell lymphoma and highlights the importance of HHV8 immunohistochemistry and molecular tests in the diagnosis of HHV8-associated lymphoma with a cutaneous presentation.

    Colonic lymphoma is an uncommon presentation of extranodal lymphoma. Colonic mucosa-associated lymphoid tissue lymphoma is a different entity from gastric mucosa-associated lymphoid tissue lymphoma, and very rare. The presentation and management of colonic mucosa-associated lymphoid tissue are highly variable in the literature. We report the case of a 59-year-old Taiwanese man who underwent a colonoscopy after a positive test for fecal occult blood. His past history included hypertension and hyperthyroidism. The colonoscopy revealed an adenomatous polyp and mucosa-associated lymphoid tissue lymphoma. We successfully performed a polypectomy and endoscopic mucosal resection. The lymphoma was staged according to the Ann Arbor system modified by Musshoff as E-I. Our patient showed no lymphoma recurrence over a 3-year follow-up. Endoscopic mucosal resection for colonic mucosa-associated lymphoid tissue lymphoma without disseminated disease may be feasible. We successfully used colonoscopic treatment without adjuvant therapy to treat early-stage pathogen-free colonic mucosa-associated lymphoid tissue lymphoma.

    Full Text Available Lymphogranuloma venereum (LGV is an uncommon, contagious, sexually transmitted disease (STD. We report a case of a 17-year-old teenager who presented with a 2-month-old ulcerous vegetant lesion in the right inguinal region. The patient was diagnosed with LGV and received erythromycin treatment. Three months after treatment, he presented with a new ulcerous lesion, very similar to the previous one, in the right supraclavicular region. He was diagnosed with a diffuse large B-cell non-Hodgkin lymphoma. Both diseases are rare in Rio de Janeiro City, Brazil, and physicians should not neglect the possibility of STDs in such cases.

    Objective: To analyze the frequencies of histological types of lymphoma, diagnosed with complete immunohistochemical profile in younger and older age group. Study Design: Cross-sectional analytical study. Place and Duration of Study: Dow Diagnostic Research and Reference Laboratory, Dow University of Health Sciences, Karachi, from January 2009 to September 2013. Methodology: Consecutive cases of lymphomas, which were diagnosed using immunohistochemistry, were analyzed according to WHO classification. Frequency and percentages for different types of lymphomas were calculated. Hodgkin and non-Hodgkin lymphomas characteristics in two age groups of less than and more than 40 years were compared, applying chi-square test. Results: Out of the 318 cases, 79 (25 percentage) were Hodgkin Lymphomas (HL) and 239 (75 percentage) were Non-Hodgkin Lymphomas (NHL). Mixed Cellularity Hodgkin Lymphoma (MCHL) was the commonest (n=48). Amongst the NHL, 215 (89.95 percentage) were B cell lymphomas and 24 (10.05percentage) were T-cell lymphomas. Diffuse Large B-Cell Lymphoma (DLBCL) was the commonest lymphoma (n=165, 69.95 percentage of NHL). Anaplastic T-Cell Lymphoma (ALCL, n=10) was the commonest T-cell lymphoma. The frequency of HL was significantly higher in the younger age group and that of NHL was higher in the older age group (p < 0.001). Primary lymph node involvement was reported in 175 (55 percentage) and cervical lymph node was the most frequent site. Extra nodal involvement was seen in 93 (29 percentage) of all cases and was reported in 87 (36.4 percentage) of NHL and 6 (7.5 percentage) of HL. The most common extra nodal site was the gastrointestinal tract. Conclusion: Hodgkin lymphoma comprises 25 percentage and non-Hodgkin lymphoma comprises 75 percentage of all lymphomas. Both occur in younger age groups than reported in the West. B-cell NHL is three times more common than T-cell lymphoma. DLBCL is the most frequent lymphoma. ALCL is the most common T-cell, and mixed

  2. Recurrent Hypoglycemia in a Patient with Hodgkin’s Lymphoma: A Case Report with Review of Literature

    2016-09-01

    Full Text Available A rare complication associated with the Hodgkin’s lymphoma is the occurrence of persistent or recurrent hypoglycemia. Although few cases have been reported in the literature, describing its pathophysiology to be multifactorial, it is difficult to determine the exact cause. We present the case of a 26 year old patient diagnosed with Hodgkin’s lymphoma who developed recurrent episodes of hypoglycemia and also discuss the various causes for its pathogenesis. In this case the serum insulin and C-peptide levels were found to be low, suggesting the presence of insulin like growth factors (IGF secreted by the cancer cells. Also, we performed a18F-2-fluoro-2-deoxy-d-glucose positron emission tomography that showed a massive tumor load. The published reports in literature have similary suggested the presence of IGF or auto-antibodies secreted by the tumor cells and also the Warburg effect in patients with high tumor load. Further research is required to clearly diagnose and define the exact etiopathogenesis of the hypoglycemia occurring in a patient with Hodgkin’s lymphoma.

    -CD40 which are active as 'naked' antibodies are required to eradicate larger tumour burdens and to cure animals. For anti-idiotype antibodies the antibody and irradiation were shown to have an additive effect in vitro and in vivo in increasing the amount of tumour apoptosis. This increased therapeutic efficacy translated into animals with large tumour burdens being cured. These results strongly imply that RIT is much more than targeted irradiation and suggest potential mechanisms for the successes in the clinic. During the course of this work a new in vivo and in vitro variant of the BCL{sub 1} tumour was isolated II-BCL{sub 1}. In contrast to the BCL{sub 1} tumour this variant establishes as a syngeneic nodular lymphoma in vivo and grows in free suspension in vitro. This tumour model has provided a useful tool to investigate the induction of apoptosis both in vitro and in vivo. Finally apoptosisinduced by irradiation and antibody were investigated in murine and human lymphoma cells in vitro. The murine radiosensitive B- and T-cell lymphomas were demonstrated to induce large amounts of early apoptosis within 24 hours. In contrast p53 mutant Burkitt's Lymphoma cell lines were resistant to irradiation and responded with delayed apoptosis reaching peak amounts at day 6. For these p53 mutated cells, DNA synthesis and mitosis are uncoupled after irradiation and these cells form increasingly large polyploid 'giant cells'. These giant cells undergo complex apoptosis and also appear to give rise to mitotically competent survivors. Thus giant cells appear to be part of a repair process and apoptosis to act not only in the death process but also in the selection of life. (author)

    The current study presents a case of primary pulmonary lymphoma (PPL) mimicking refractory lung abscess that was diagnosed at autopsy. An 80-year-old male with clinically inapparent aspiration presented with a large cavitated mass and pleural effusion. A lung abscess and empyema was diagnosed, therefore, antibiotics were administered and the pleural effusion was drained. Various examinations, including a biopsy, yielded no specific diagnosis. The lesion was considered inoperable due to the poor general condition of the patient. Subsequently, the mass that had been diagnosed as a refractory lung abscess became enlarged and a repeat biopsy resulted in a diagnosis of diffuse large B-cell lymphoma. The patient succumbed to sudden respiratory failure, and the final diagnosis of PPL was confirmed at autopsy. PPL is a rare disease that accounts for 0.45% of all pulmonary malignant tumors and is difficult to diagnose in inoperable cases. Therefore, patients with PPL who do not undergo surgery can be misdiagnosed and consequently treated inappropriately. PPL should therefore be considered in the differential diagnosis of a refractory lung abscess.

    Full Text Available Primary non-Hodgkin′s lymphoma of the common bile duct is extremely rare. We present a case with history of inflammatory bowel disease and clinical manifestations of obstructive jaundice. Abdominal magnetic resonance imaging with magnetic resonance cholangiopancreatography (MRCP was done and demonstrated tight stricture at the middle part of common bile duct, and radiological findings were supportive of extra-hepatic cholangiocarcinoma. Whipple′s procedure was performed and the case was histopathologically proven to be non-Hodgkin′s lymphoma of follicular subtype involving the common bile duct. Lymphoma of the hepatobiliary system is usually present as secondary manifestation of systemic malignant lymphoma. However, primary malignant lymphomas arising from the hepatobiliary tree are extremely rare. The radiological appearance of common bile duct lymphoma is very similar to cholangiocarcinoma, making preoperative diagnosis very difficult, as in our present case. We also compare the imaging findings of our case to those seen in reported cases of follicular lymphoma of the common bile duct.

    Most high-grade B-cell lymphomas with MYC and BCL2 and/or BCL6 rearrangements are aggressive B-cell lymphomas. Occasional double-hit follicular lymphomas have been described but the clinicopathological features of these tumors are not well known. To clarify the characteristics of double-hit follicular lymphomas, we analyzed 10 cases of double-hit follicular lymphomas and 15 cases of high-grade B-cell lymphomas with MYC and BCL2 and/or BCL6 rearrangements for clinicopathological and genome-wide copy-number alterations and copy-neutral loss-of-heterozygosity profiles. For double-hit follicular lymphomas, the median age was 67.5 years (range: 48-82 years). The female/male ratio was 2.3. Eight patients presented with advanced clinical stage. The median follow-up time was 20 months (range: 1-132 months). At the end of the follow-up, 8 patients were alive, 2 patients were dead including 1 patient with diffuse large B-cell lymphoma transformation. Rearrangements of MYC/BCL2, MYC/BCL6, and MYC/BCL2/BCL6 were seen in 8, 1, and 1 cases, respectively. The partner of MYC was IGH in 6 cases. There were no cases of histological grade 1, 4 cases of grade 2, 5 cases of grade 3a, and 1 case of grade 3b. Two cases of grade 3a exhibited immunoblast-like morphology. Immunohistochemistry demonstrated 9 cases with ≥50% MYC-positive cells. There was significant difference in MYC intensity (P=0.00004) and MIB-1 positivity (P=0.001) between double-hit follicular lymphomas and high-grade B-cell lymphomas with MYC and BCL2 and/or BCL6 rearrangements. The genome profile of double-hit follicular lymphomas was comparable with conventional follicular lymphomas (GSE67385, n=198) with characteristic gains of 2p25.3-p11.1, 7p22.3-q36.3, 12q11-q24.33, and loss of 18q21.32-q23 (Phit follicular lymphomas had fewer copy-number alterations and minimal common region of gain at 2p16.1 (70%), locus also significant against conventional follicular lymphomas (P=0.0001). In summary, double-hit follicular

    Chemo- and radiotherapy are treatments very helpful to cure cancers but are also well known for adverse effects such as secondary cancers. Breast cancers following Hodgkin lymphoma have been relatively well studied. Breast cancers after radiotherapy covering or nearby breasts or nipples are usually carcinomas or secondary sarcomas. Among the big cohort of patients treated for breast carcinomas, breast lymphomas developed in the same area are not usual. Nevertheless, published studies described a significant increased risk of non-Hodgkin lymphoma after initial radiotherapy for a solid cancer. Here, we report a case of a secondary breast lymphoma observed in a 53-year-old woman treated 13 years before for a ductal carcinoma and analyse such second tumors with a review of the literature. This case report emphasizes the importance of the biopsy in case of recurrence in breast cancer to give the appropriate treatment.

    Primary cutaneous marginal zone lymphoma most commonly represents an indolent form of cutaneous B cell lymphoma. However, epidermotropic marginal zone lymphoma, blastic marginal zone lymphoma and B cell dominant variants without isotype switching can be associated with extracutaneous dissemination. The presumptive cell of origin is a post germinal center B cell with plasmacytic features. In the extracutaneous setting, however, a naïve B cell origin has been proposed for a subset of marginal zone lymphomas, notably splenic marginal zone lymphoma. The author encountered 11 cases of atypical lymphocytic infiltration of the skin primarily occurring in older individuals with an upper arm and head and neck localization; there was a reproducible pattern of diffuse and nodular infiltration by small monomorphic-appearing B cells. Phenotypically, the infiltrate was one predominated by B cells exhibiting CD23 and IgD positivity without immunoreactivity for CD38 and there were either no plasma cells or only a few without light chain restriction. In cases presenting with a solitary lesion complete excision and/or radiation led to successful disease remission in all cases without recurrence or metastatic disease. Of three cases with multiple initial lesions, evidence of extracutaneous disease was seen in two cases and recurrence occurred in one case. No patients have died of lymphoma. Longer term follows up and additional cases are needed to determine if this subset of marginal zone lymphoma is associated with a worse prognosis. Copyright © 2018. Published by Elsevier Inc.

    Survival and prognostic factors were retrospectively analyzed in 10 patients with primary intracranial lymphoma and 7 patients with secondary intracranial lymphoma from 1983 to 1994 at Kagoshima University Hospital and affiliated hospitals. The 1-year survival rate was 62.5% in primary cases and 35.7% in secondary cases. In primary cases, there were no significant differences in survival between surgically treated and non-surgically treated cases, or between multiple-lesion and solitary-lesion cases. In secondary cases with a solitary lesion, excluding one case of Hodgkin's lymphoma, survival was better in cases treated within 3 months after the appearance of neurologic symptoms than in cases treated over 3 months after the appearance of symptoms. There was no significant difference in survival between cases treated with whole-brain irradiation of 40 Gy or more and those treated with less than 40 Gy. The results suggest that intracranial involvement of an extracranial malignant lymphoma should be diagnosed and treated as early as possible. (author)

    Full Text Available Calcitriol-mediated hypercalcemia is a frequent manifestation of hematological malignancies. However, there are a few reports of cases presenting with increased angiotensin-converting enzyme (ACE level, which suggests a possible mechanism similar to that of granulomatous diseases. We present a patient with hypercalcemia, normal parathyroid hormone, and parathyroid hormone-related protein levels but high calcitriol and ACE levels that, after further investigation, was diagnosed with bilateral adrenal non-Hodgkin's B-cell lymphoma. Primary adrenal lymphoma represents only 1% of all non-Hodgkin's lymphomas and is usually asymptomatic but should be considered by clinicians among the malignancies that cause calcitriol-mediated hypercalcemia.

When Burkitt's lymphoma was considered separately from other NHL, the agreement between clinical diagnoses in Uganda and pathological diagnoses in Uganda was 69% (95% CI 59–77; kappa 0.56; P < 0.0001, and the corresponding agreement between pathological diagnoses assigned in The Netherlands was 32% (95% CI 24–41; kappa 0.05; P = 0.326. The agreement between all pathological diagnoses assigned in Uganda and The Netherlands was 36% (95% CI 28–46; kappa 0.11; P = 0.046.Conclusion: Clinical diagnosis of NHL in Uganda has a high probability of error compared with pathological diagnosis in Uganda and in The Netherlands. In addition, agreement on the pathological diagnosis of NHL between Uganda and The Netherlands is very low.Keywords: Africa, Epstein-Barr virus, non-Hodgkin lymphoma, Burkitt's lymphoma, cancer

    We examined malignant lymphomas and polymorphic reticulosis of nasal cavity, nasopharynx, and palate, diagnosed at Korea Cancer Center Hospital from 1987 to 1996. With immunophenotypic study, we reclassified nasal/nasopharyngeal lymphomas into three categories: CD56-positive T/NK lymphoma, CD56-negative lymphoma and B-cell lymphoma. Malignant lymphomas of nasal cavity, nasopharynx and palate were 95 patient, that comprised 11% of the total lymphoma cases, and it was the most common extranodal lymphoma. Twenty-five percent were B-cell lymphomas and 75 % were T/NK lymphomas. According to site, nasal cavity was the most frequent and 91 % of nasal cavity lymphomas were T/NK type. CD56-positive T/NK comprised 82 % of total T/NK lymphomas and CD56-negative cases were 18 %. In 89 % of total T/NK lymphomas, many tumor cells expressed EBER-1 in their nuclei (CD56+ T/NK lymphoma: 97 % of EBV expression, CD56-T-cell lymphoma; 60%). Only one case (5%) of B-cell lymphoma showed EBER-1 positivity in a few cells. CD56+ T/NK lymphomas showed significantly more angiocentricity and severe necrosis than CD56- cases. Although it has no statistical significance, T/NK lymphomas has a tendency to lower survival rates than B-cell lymphomas at 1 year and 2 year. CD56+ T/NK lymphomas has a tendency to lower survival than CD56- T/NK lymphomas (p > 0.05). Our results of this project will serve important basic materials in diagnosing and studying lymphoma.

    Purpose Andrographolide is a diterpenoid lactone isolated from Andrographis paniculata (King of Bitters), an herbal medicine used in Asia. It has been reported to have anti-inflammatory, antihypertensive, anti-viral and immune-stimulant properties. Furthermore, it has been shown to inhibit cancer cell proliferation and induce apoptosis in leukemia and solid tumor cell lines. Experimental Design We studied the Burkitt p53 mutated Ramos cell line, the mantle-cell lymphoma (MCL) line Granta, the follicular lymphoma (FL) cell line HF-1 and the diffuse large B-cell lymphoma (DLBCL) cell line SUDHL4, as well as primary cells from patients with FL, DLBCL, and MCL. Results We found that andrographolide resulted in dose- and time-dependent cell death as measured by MTT. Andrographolide significantly increased reactive oxygen species (ROS) production in all cell lines. To determine mechanism of cell death, we measured apoptosis by Annexin-V/propidium iodide (PI) in the presence and absence of the antioxidant N-acetyl-L-cysteine (NAC), the glutathione-depleting agent buthionine sulfoxamine (BSO), or caspase inhibitors. We found that apoptosis was greatly enhanced by BSO, blocked by NAC, and accompanied by PARP cleavage and activation of caspases 3, 8 and 9. We measured BAX conformational change, and mitochondrial membrane potential, and using mouse embryonic fibroblast (MEF) Bax/Bak double knockouts (MEFBax−/−/Bak−/−), we found that apoptosis was mediated through mitochondrial pathways, but dependent on caspases in both cell lines and in patient samples. Conclusions Andrographolide caused ROS-dependent apoptosis in lymphoma cell lines and in primary tumor samples, which was enhanced by depletion of GSH and inhibited by NAC or the pan-caspase inhibitor Z-VAD-FMK. Further studies of diterpenoid lactones in lymphoma are warranted. PMID:20798229

    Neck pain is a common reason for seeking medical attention. It affects at least 15% of the labor force and up to 40% of individuals whose occupation is hazardous. On the other hand, primary bone lymphoma is a very rare disease (less than 1% of all malignant bone tumors), and the relationship between the 2 has rarely been mentioned. We report the case of a patient who had a 1-month history of neck pain. The main symptom was pain on palpation of C2-C6 cervical spinous processes and contracture of the trapezius muscle that did not cease with conventional treatment. Imaging studies indicated an abnormality. He underwent surgery and the results of vertebral biopsy were compatible with diffuse large B-cell lymphoma. He was treated with radiotherapy with a good outcome. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Reumatología y Colegio Mexicano de Reumatología. All rights reserved.

    Background. Primary lymphoma of the colon is rare, constituting 0.4% of primary colonic malignancies and usually involves cecum or rectum. The aim of this paper is to present the role and the importance of double contrast barium enema (DCBE) in the diagnostic process. Case report. A 77 years old male was admitted because of suspected inflammation in the area of total endoprosthesis of the left hip, inserted ten years before. Listeria monocytogenes was isolated from the aspirate and the patient treated with antibiotics. Twenty years ago the patient underwent nephrectomy because of hypernephroma of left kidney. At the time of admission he had sideropenic anaemia and he was febrile. Conclusion. The patient underwent many diagnostic procedures: ultrasound (US), computed tomography (CT), double contrast barium enema, which showed a tumour in the cecum, small bowel follow-through and scintigraphy. The diagnosis of primary non-Hodgkin lymphoma was established by histology after biopsy at colonoscopy. (author)

    , respectively. In the case of Waldeyer's ring, DLBCL was dominant (80%) in incidence. In the case of thyroid gland, MALT-L was 52% of the total and in the case of sinonasal cavity NK/T-L was 60% of the total in incidence. According to the REAL classification, the 5-year PFS rates for patients with DLBCL, MALT-L, NK/T-L and mantle cell lymphoma were 64%, 83%, 50% and 25%, respectively (p<0.06). On the other hand, according to the Working Formulation, the 5-year PFS rates for patients with follicular lymphoma, diffuse small cleaved cell lymphoma, diffuse mixed cell lymphoma, diffuse large cell lymphoma and immunoblastic lymphoma were 71%, 57%, 79%, 56% and 50%, respectively (p<0.73). The 5-year PFS rates for patients with Waldeyer's ring NHL, thyroid NHL and sinonasal NHL were 61%, 49% and 74%, respectively (p=0.34). The 5-year PFS rates for patients treated with radiation therapy alone and combined modality were 36% and 75%, respectively (p<0.01). The 5-year PFS rates for patients with low grade of IPI and low-intermediate grade were 70% and 59%, respectively (p<0.01). There was no difference of PFS according to the dose and fields of radiotherapy. The central pathological review was very important in conducting the multi-center clinical trials and multi-institutional surveys. The REAL classification and IPI were useful in predicting the survival of patients with localized extra-nodal NHL. (author)

    261 case historys of malignant non-Hodgkin-lymphomas were analysed in the years from 1969 until 1978 in the 'Radiologische Universitaetsklinik Kiel'/West-Germany. 18 Patients got a central nervous complication of Non Hodgkin-Lymphoma earlier or later, a percentage of about 7. There were 7 cases of lymphoblastic lymphoma (LB), a percentage of 10 for this entity. In the group of immunoblastic lymphoma (IB) 6 cases of central nervous infiltration were detected, that is a ratio of 7.7 percent. 4 case histories M. Brill-Symmers (CC/CB) were complicated by central nervous dissemination, a percentage of 5.3. Patients with lymphoblastic lymphoma have the highest risk of central nervous complication. The beginning of central nervous dissemination in the single case histories is very different between the histological groups. Patients with lymphoblastic lymphoma suffered from central nervous complication in an early phase of history, in cases of M. Brill-Symmers central nervous infiltration can occur also in a late phase. The results may determine the discussion about stratifying of radiotherapy. Early radiotherapy including central nervous system may be discussed and investigated in special histological entities of malignant non-Hodgkin-lymphoma. (orig.) [de

    2014-03-01

    Full Text Available Primary cutaneous CD 30+ anaplastic large cell lymphoma is part of the spectrum of primary cutaneous CD30 + lymphoproliferative disorders, together with lymphomatoid papulosis. Its frequency is less than 0.5 x 100 000 inhabitants per year. It accounts for a very small proportion of non-Hodgkins lymphomas. The case of an 80-year-old female patient whose diagnosis was established in 2006 because of lesions on the face and neck is presented. The lesions continued to grow in an exaggerated fashion lately leading to deformity of her face. She was admitted due to neurological manifestations unrelated to the lesions. The presentation of this case is necessary because it requires performing differential diagnosis in clinical practice. Given its rarity, it is of interest to the medical community, especially trainees.

    Directory of Open Access Journals (Sweden)

    Jeffrey Carson

    2012-01-01

    Full Text Available We present a case of a 3-year-old male originally diagnosed with a CD30+ anaplastic cutaneous T-cell lymphoma with no evidence of systemic disease after CT scan, PET scan, and bone marrow aspiration. Sentinel lymph node biopsy (SLNB was performed as an additional step in the workup and showed microscopic disease. Current management/recommendations for cutaneous T-cell lymphoma do not include SLNB. Medical and surgical management of cutaneous malignancies is dramatically different for local versus advanced disease. Therefore adequate evaluation is necessary to properly stage patients for specific treatment. Such distinction in extent of disease suggests more extensive therapy including locoregional radiation and systemic chemotherapy versus local excision only. Two international case reports have described SLNB in cutaneous T-cell lymphoma with one demonstrating evidence of node positive microscopic disease despite a negative metastatic disease workup. This case is being presented as a novel case in a child with implications including lymphoscintigraphy and SLNB as a routine procedure for evaluation and staging of cutaneous T-cell lymphoma if the patient does not demonstrate evidence of metastatic disease on routine workup.

  5. Isolated orbital mass as the primary presentation of a triple-hit lymphoma transformed from a systemic follicular lymphoma

    2018-06-01

    Full Text Available Purpose: Triple-hit lymphoma is a highly aggressive B-cell lymphoma. We report a case of triple-hit lymphoma transformed from systemic follicular lymphoma (FL after 9-year remission and presented primarily as an isolated orbital mass without systemic symptoms or lymphadenopathy. Observations: A 58-year-old female presented with intermittent vertical binocular diplopia, left upper eyelid swelling and pain and was found to have a 2.9 cm orbital mass. Histological section revealed a CD10-positive large B-cell lymphoma, consistent with transformation of FL. Fluorescent in situ hybridization (FISH analysis demonstrated rearrangements involving C-MYC, BCL-2 and BCL-6 genes, indicating a high grade, triple-hit lymphoma. Conclusions and importance: Triple-hit lymphoma transformed from a low-grade lymphoma may initially present as an isolated orbital mass without systemic evidence of transformation. Early recognition of double or triple-hit lymphomas is important since these patients require aggressive chemotherapy. Keywords: Lymphoma, Triple-hit lymphoma, Orbital mass

    Full Text Available Abstract Only a few cases of extranodal Epstein-Barr virus (EBV-associated B-cell lymphomas arising from patients with angioimmunoblastic T-cell lymphoma (AITL have been described. We report a case of AITL of which secondary cutaneous EBV-associated diffuse large B-cell lymphoma (DLBCL developed after the initial diagnosis of AITL. A 65-year-old Chinese male patient was diagnosed as AITL based on typical histological and immunohistochemical characteristics in biopsy of the enlarged right inguinal lymph nodes. The patient initially received 6 cycles of chemotherapy with CHOP regimen (cyclophosphamide, vincristine, adriamycin, prednisone, but his symptoms did not disappear. Nineteen months after initial diagnosis of AITL, the patient was hospitalized again because of multiple plaques and nodules on the skin. The skin biopsy was performed, but this time the tumor was composed of large, polymorphous population of lymphocytes with CD20 and CD79a positive on immunohistochemical staining. The tumor cells were strong positive for EBER by in situ hybridization. The findings of skin biopsy were compatible with EBV-associated DLBCL. CHOP-R chemotherapy (cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab was then administered, resulting in partial response of the disease with pancytopenia and suppression of cellular immunity. To our knowledge, this is the first case of cutaneous EBV-associated DLBCL originated from AITL in Chinese pepole. We suggest the patients with AITL should perform lymph node and skin biopsies regularly in the course of the disease to detect the progression of secondary lymphomas.

    Para neoplastic cerebellar degeneration (PCD) is a type of para neoplastic neurological disorder (PND) that is associated with many solid tumors, Hodgkins lymphoma (HL) and very rarely with non-Hodgkin lymphoma (NHL). We report a case of PCD associated with gastric diffuse large B-cell lymphoma (DLBCL) in a patient who presented with acute onset of giddiness and double vision and had complete remission of the gastric lesion and marked improvement of cerebellar syndrome with rituximab-based combination chemotherapy. A brief review of the literature is also presented.

    2015-10-01

    Full Text Available Purpose: To report a case of a patient with primary vitreoretinal lymphoma masquerading as retinitis. Methods: Retrospective review of the patient's clinical, histopathological and imaging records. Results: Cytopathology was negative for malignancy, and preliminary polymerase chain reaction results supported the diagnosis of varicella zoster virus retinitis. Therefore, the patient was treated with antiviral therapy. However, under this treatment, the retinitis progressed. As a result, primary vitreoretinal lymphoma was suspected, and empirical treatment with intravitreal methotrexate injections was started. Under this treatment, the ocular features improved. Five months after initial ocular presentation and ocular resolution, the patient presented with central nervous system lymphoma. Conclusion: This case should raise the awareness of the variable clinical presentations, the challenging diagnosis and treatment of primary vitreoretinal lymphoma. All cases should be continuously systemically evaluated.

    1984-05-01

    A retrospective study of 21 patients who had suffered from gastrointestinal lymphoma was carried out. Gastric involvement was more common than involvement of the small or large intestine and carried a better prognosis. Gastrointestinal lymphoma generally occurs most frequently during the fourth to seventh decades of life. In our study, however, five lymphomas occurred in patients under 20 years of age. Clinical symptoms were nonspecific, and abdominal mass was found in only 15% of the patients on clinical examination. All patients were explored, 17 underwent resection, and 4 laparotomy and biopsy. Five-year survival was much better for patients who had undergone resection. Survival was inversely proportionate to the extent of nodal spread. Multiple lesions on the same organ yielded a 5-year survival of 20%, while a single lesion offered a 55% chance of 5-year survival. Diffuse histiocytic lymphoma was the commonest type, followed by the poorly differentiated lymphocytic type. A longer survival rate was present in the lymphocytic type. However, the highest survival rate was in those patients in whom definite resections of the lesion were performed followed by radiation and chemotherapy, especially for gastric tumor.

    We report the first case of primary mucosa-associated lymphoid tissue (MALT) lymphoma of the vagina, the diagnosis of which is supported by genetic and immunophenotypic studies. A 65-year-old, para 2 woman presented to our hospital in July 1997 with a history of prolonged vaginal discharge. Although cytologic examination suggested possible malignancy, a biopsy of the vaginal wall was diagnosed as chronic inflammation. In June 2000, she underwent gynecologic examination because of anuria. Excisional biopsy revealed subepithelial infiltration of atypical lymphoid cells that stained for CD20, CD79a, and BCL-2; stained weakly for IgM; and did not stain for CD3, CD5, CD7, CD10, CD56, CD23, and IgD, suggesting marginal zone B-cell lineage. Monoclonality was detected by Southern blot analysis, and this patient was finally diagnosed as having primary MALT lymphoma of the vagina. She received 3 cycles of chemotherapy (THP-COP) and concurrent radiation to the whole pelvis. The patient is alive and well 40 months after treatment. Because the vagina is one of the mucosa-associated tissues, MALT lymphoma, though rare, must be included in the differential diagnosis of the vaginal neoplasms.

    2017-08-01

    Waldenström macroglobulinemia (WM) is a lymphoproliferative lymphoma that is characterized by monoclonal immunoglobulin M (IgM) protein and bone marrow infiltration. Its incidence is rare and rarer still is its ability to transform to a B-cell lymphoma, particularly the aggressive diffuse large B-cell lymphoma, which bodes a poor prognosis. When transformation includes mutations of MYC, BCL-2 and/or BCL-6, it is known as a 'double hit' or 'triple hit' lymphoma respectively. This paper presents a rare case of WM with mutations positive for MYC and BCL2, making it a case of double hit B-cell lymphoplasmacytic lymphoma with plasmatic differentiation without morphological transformation to aggressive histology like DLBCL. The paper also broadens to include discussions on current topics in the classification, diagnosis, possible causes of transformation, and treatment of WM, including transformation to double hit lymphoma. The significance of this case lies in that the presence of double hit lymphoma-like genetic mutations in WM have not been previously described in the literature and potentially such changes are harbinger of extra-nodal presentation, aggressive growth, and possibly poor prognosis, if data from other double-hit lymphoma are extrapolated.

    1983-01-01

    This paper reports a case of malignant lymphoma which was originated from the breast, followed by multiple involvement in the brain, and finally developed intraocular infiltration. These lesions disappeared by irradiation therapy. A 51 years old housewife was admitted to our hospital for the further evaluation and treatment of decreased bilateral visual acuity on May 1981. On May 1976, she noticed a solid tumor of the left breast, and total mastectomy disclosed malignant lymphoma (non-Hodgkin lymphoma, lymphocytic type). On August 1980, she developed diplopia and amnesia. CT scan revealed multiple involvements in brain and cobalt therapy resulted in good response. The ophthalmologic diagnosis was uveitis, but it was impossible to rule out the ophthalmic infiltration of malignant lymphoma and 60 Co irradiation (total 2,976 rad) to the bilateral eyes and systemic CHOP therapy were carried out. Consequently, her visual acuity recovered to 0.6, and she is now following ambulatory course. Although non-Hodgkin lymphomas have been reported to originate frequently from non lymphoid tissues, the breast as the primary site is rare and the intracerebral infiltration as an involvement of central nervous system is quite rare. Furthermore, malignant lymphoma of the eyes, especially intraocular involvement is infrequent in incidence. The diagnosis of uveitis due to malignant lymphoma is considered to be difficult because of lack in specific findings. (author)

    Full Text Available Primary cutaneous large B-cell lymphoma (Bcl is defined as a lymphoma composed of large cells constituting more than 80% of the infiltrate and absence of extracutaneous involvement after staging investigations. In the new World Health Organization/European Organization for Research and Treatment of Cancer classification, cutaneous Bcls with large cells are of three types - primary cutaneous large Bcl leg type (PCLBCLLT, primary cutaneous follicle center lymphoma diffuse type (PCFCLDT, and primary cutaneous large Bcls other (PCLBCLO. These three different types are distinct in terms of their clinicopathological features and survival. The PCLBCLO has intermediate features between those of PCLBCLLT and PCFCLDT. We present a case of PCLBCLO in a 57-year-old male who presented with a scalp swelling. Ultrasonography examination was suggestive of a sebaceous cyst. Computed tomography scan revealed the presence of an ill-defined hyperdense region in the soft tissue of the scalp region extending into the deeper layers of the scalp. Fine-needle aspiration cytology (FNAC revealed the presence of atypical lymphoid cells. Diagnosis was confirmed by biopsy and immunohistochemistry. Patient received rituximab combined with doxorubicin, vincristine, cyclophosphamide, and prednisolone regimen with complete resolution of the lesion. We present this case for its rarity, the utility of FNAC in early diagnosis, and to discuss the differential diagnosis.

    Non-Hodgkin's lymphomas are a varied and complex group of diseases that must be distinguished from Hodgkin's disease. The latter almost always begins in lymph nodes and spreads primarily in an axial fashion; non-Hodgkin's lymphomas may begin either in lymph nodes or in extranodal tissue and can spread both in an axial fashion and centrifugally. Because of changes in pathology terminology and the introduction of a classification using cell surface markers, many prognostic groups of patients with lymphomas have evolved. Therapeutic choices and prognosis are greatly influenced by variations in anatomic sites and extent of disease. Currently, the decisions on management require a balancing of radiation therapy with systemic chemotherapy. In some cases, radiation therapy alone may be sufficient; however, because most patients with non-Hodgkins's lymphomas tend to have advanced disease, a large percentage of patients will be managed with chemotherapy alone or in combination with radiation therapy

    Estimation of kidney function by measuring serum creatinine is one the commonest laboratory tests conducted in clinical practice. Enzymatic methods are often used to measure serum creatinine. Clinicians should be aware of the limitations of these methods, such as test interference with paraproteins.We present a case of falsely elevated serum creatinine in a patient referred for renal biopsy. The combination of fluctuating creatinine and normal blood urea level was unusual. Serum protein electrophoresis revealed the presence of an IgM paraprotein. Further investigations confirmed an underlying diagnosis of lymphoplasmacytoid lymphoma. This case highlights how IgM paraprotein can interfere with creatinine estimation by enzymatic assay and the utility of alternative methods of estimating serum creatinine. 2017 BMJ Publishing Group Ltd.

    We are reporting the case of a 58-year-old woman with history of bilateral silicone breast implants for cosmetic augmentation. At 2-year interval from receiving the breast implants, she presented with swelling of the right breast with associated chest wall mass, effusion around the implant, and axillary lymphadenopathy. Pathology confirmed breast implant-associated anaplastic large cell lymphoma (stage III, T4N2M0, using BIA-ALCL TNM staging and stage IIAE, using Ann-Arbor staging). The patient underwent bilateral capsulectomy and right partial mastectomy with excision of the right breast mass and received adjuvant CHOP chemotherapy and radiation to the right breast and regional nodes. Since completion of multimodality therapy, the patient has sustained remission on both clinical exam and PET/CT scan. We report this case and review of the literature on this rare form of lymphoma.

    Full Text Available A post menopausal lady presented with lump lower abdomen and bleeding per vaginum. USG revealed diffuse enlargement of the uterus. On hysterectomy, a grossly enlarged uterus with cystic left ovary were found. Hysterectomy was done and uterus with bilateral adnexa submitted for histopathological examination. Microscopic examination of the body of uterus revealed sheets of small lymphoid cells were found to replace the endo- and myo-metrium. These cells have small nuclei with clumped chromatin, and no prominence of nucleoli. They are not forming lymphoid follicles or germinal centers. Similar lymphoid cells were also found in the left ovary admixed with ovarian stroma. On IHC these cells were found to be CD45, CD20, CD23 positive, and negative for CD3 , CK and SMA. The case is diagnosed as a primary small lymphocytic lymphoma of uterus with left ovarian spread.

    Two cases of cytomegalic inclusion disease complicating chronic granulocytic leukemia and subacute lymphocytic leukemia in adult Japanese males in Nagasaki, Japan are reported. Both cases had concomitant pulmonary infection by pneumocystis carinii and both were exposed to the atomic bomb in 1945. It is believed these are the first reported autopsy cases of adult cytomegalic inclusion disease in which typical cytomegalic inclusion bodies were seen in the parenchymal cells of the salivary glands. Previously reported cases of adult cytomegalic inclusion disease complicating leukemia and malignant lymphoma are briefly summarized. Present knowledge of the relationship between cytomegalic and pneumocystis infections and association with lymphoma and leukemia is reviewed. The possible roles of chemotherapeutic agents and of radiation in the development of the cytomegalic and pneumocystis infections are also briefly discussed. 43 references, 4 figures, 2 tables.

    at the Instituto Materno-Infantil Professor Fernando Figueira (IMIP over a 9-year period, and also to describe their survival rates and possible associations between the survival rates and the clinical and demographic characteristics analyzed in the study. METHODS:This was a cross-sectional study. Data were collected by a retrospective review of the charts of all 110 patients admitted to our unit during the period of May 1994 through May 2003. Probability of survival was calculated in accordance with the techniques of Kaplan-Meier, using log rank to evaluate differences between the groups. RESULTS:The average age was 6.1 years. The male/female ratio was 2.4:1. The most frequent histological subtype was Burkitt's lymphoma. The majority of patients had been diagnosed with advanced disease (stage III or IV of Murphy's Classification and was from rural areas. Family income per capita was lower than 1/2 minimum wage in 36.4% of cases; maternal illiteracy was observed in 12.7% of cases. The 5-year overall survival and disease-free survival rates were 70±4% and 68.4±4%, respectively. None of the clinical-demographic characteristics had a significant association with the probability of survival (p > 0.05. CONCLUSION: Children admitted to the IMIP seemed to be affected by non-Hodgkin lymphoma at a younger age, with a higher incidence of Burkitt's lymphoma and with survival rates similar to those described in the literature of developed countries. No clinical demographic characteristics had a statistically significant association with prognosis.

    Objective: To analyze MR imaging manifestations of spinal area lymphoma in order to improve the recognition and understanding of the disease. Methods: A group of 45 patients with pathologically or clinically proven spinal area lymphoma were reviewed. Five cases were primary NHL, 40 cases were secondary with 9 HL and 31 NHL (27 B-cell type NHL and 4 T-cell type NHL). MR Imaging findings were analyzed and correlated with clinical and pathologic findings. Results: (1) Location of lesions: 13 cases were focal type and 32 cases were multifocal type. All of the 5 patients with primary lymphoma were focal type, while 32 of 40 eases of secondary lymphoma were multifocal type. (2)Type of lesions: (1) Vertebral destruction: 27 cases manifested as bone destruction with 23 of them had soft tissue mass and the extent of soft tissue masses were larger than that of bone destruction in 18 eases. (2) Soft tissue masses: 6 cases manifested as soft masses without obvious bone destruction, of which 5 cases had soft tissue masses imbedded vertebrae and communicated paravertebral and epidural spaces through intervertebral foramen. (3) Bone marrow infiltration: 9 cases of secondary spinal lymphoma had signal intensity changes of bone marrow without obvious cortical bone destruction and soft tissue mass. (4) Spinal cord infiltration: 3 cases of secondary spinal lymphoma had spinal cord swelling and signal intensity changes. (3) MRI findings: all lesions of bone destruction and marrow infiltration manifested as hypointense on T 1 -weighted images, hypointense, isointense or hyperintense on T 2 -weighted images and hyperintense on T 2 -weighted images with fat-suppression technique. All soft tissue masses were homogeneous hypointense on T 1 -weighted images and hyperintense on T 2 -weighted images. After intravenous injection of contrast media, the lesions of the bone and the soft tissue showed mild or moderate enhancement without remarkable cystic degeneration and necrosis. Conclusions

    Differentiating low-grade lymphoma from preexisting sarcoidosis is difficult because of their pathological similarity. This article describes a case of pulmonary mucosa-associated lymphoid tissue lymphoma associated with pulmonary sarcoidosis. The patient, a 45-year-old Japanese man, presented with a 10-year history of pulmonary sarcoidosis and 5-year history of ocular sarcoidosis with histologic findings. Because only the right S3 lung nodule had gradually enlarged, partial resection was performed. Pathological study revealed noncaseous epithelioid granulomas with lymphoplasmacytic proliferation but also marked lymphoid cell proliferation with lymphoepithelial lesion findings that differed from findings of typical sarcoid lesions. Our lymphoepithelial lesion evaluation via immunohistochemistry and analysis of Ig heavy-chain gene rearrangements with assessment of Propionibacterium acnes-specific antibody reactions allow us to report, for the first time, this case of pulmonary mucosa-associated lymphoid tissue lymphoma associated with pulmonary sarcoidosis in exactly the same location, which may be significant for differentiating these diseases and understanding their pathogenic association.

    Full Text Available We present a case of a patient with HIV/AIDS who presented with a tender left lower extremity cutaneous mass over a site of previous cryptococcal infection and was found to have plasmablastic lymphoma (PBL. The incidence of PBL is estimated to account for less than 5% of all cases of non-Hodgkin lymphoma (NHL in HIV-positive individuals. In fact, there were only two reports of extraoral PBL at the time of a 2003 review. PBL in HIV-positive individuals is an aggressive malignancy that tends to occur in middle-aged males with low CD4 counts, high viral loads, and chronic HIV infection. The definitive diagnosis can be made with biopsy which typically shows malignant lymphoid cells that stain positive for plasma cell markers and negative for B-cell markers. The most common treatment is chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP or CHOP-like regimens, but the overall survival rate is poor despite its relative responsiveness to chemotherapy. This case highlights the challenges that remain in improving clinical outcomes, the importance of antiretroviral therapy and HIV disease control, and a potential association between a chronic inflammatory state caused by disseminated Cryptococcus and tumorigenesis in individuals with PBL.

    Inoculation of hamadryas baboons with blood of leukemia ill people-induced malignant non-Hodgkin's lymphoma in experimental animals for a very considerable latency period. At close contact of inoculated baboons with healthy non-inoculated animals, the lymphoma spread between them. The epidemiological analysis, postmortem examination, histological analysis, tissue culturing, and PCR were used for the diagnostics of lymphoma and pre-lymphoma, purification, identification of STLV-1, and HVP viruses. Characteristic clinical and morphological signs designated by us as pre-lymphoma often precede the lymphoma development. In some cases, pre-lymphoma does not develop in lymphoma because animals die from various diseases and do not reach the point of the lymphoma development. The horizontal transmission of lymphoma arising with the participation of T-lymphotropic retrovirus STLV-1 is shown. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Cancer cells subvert host immune surveillance by altering immune checkpoint (IC) proteins. Some Epstein-Barr virus (EBV)-associated tumors have higher Programmed Cell Death Ligand, PD-L1 expression. However, it is not known how EBV alters ICs in the context of its preferred host, the B lymphocyte and in derived lymphomas. Here, we found that latency III-expressing Burkitt lymphoma (BL), diffuse large B-cell lymphomas (DLBCL) or their EBNA2-transfected derivatives express high PD-L1. In a DLBCL model, EBNA2 but not LMP1 is sufficient to induce PD-L1. Latency III-expressing DLBCL biopsies showed high levels of PD-L1. The PD-L1 targeting oncosuppressor microRNA miR-34a was downregulated in EBNA2-transfected lymphoma cells. We identified early B-cell factor 1 (EBF1) as a repressor of miR-34a transcription. Short hairpin RNA (shRNA)-mediated knockdown of EBF1 was sufficient to induce miR-34a transcription, which in turn reduced PD-L1. MiR-34a reconstitution in EBNA2-transfected DLBCL reduced PD-L1 expression and increased its immunogenicity in mixed lymphocyte reactions (MLR) and in three-dimensional biomimetic microfluidic chips. Given the importance of PD-L1 inhibition in immunotherapy and miR-34a dysregulation in cancers, our findings may have important implications for combinatorial immunotherapy, which include IC inhibiting antibodies and miR-34a, for EBV-associated cancers.

The objective was to examine the effects of BCG and smallpox vaccinations on subsequent risk of lymphoma and leukaemia in a Danish population experiencing rapid out-phasing of these vaccines...... cohort and analysed in a case-cohort design. BCG vaccination reduced the risk of lymphomas (HR=0.49 (95% CI: 0.26-0.93)), whereas smallpox vaccination did not (HR=1.32 (0.56-3.08)). With the small number of leukaemia cases, the analysis of leukaemia had limited power (BCG vaccination HR=0.81 (0.......31-2.16); smallpox vaccination HR=1.32 (0.49-3.53)). The present study with very reliable vaccine history information indicates a beneficial effect of BCG vaccination on the risk of lymphomas....

    Thyroid lymphoma is a rare disease entity of elderly females. Chronic lymphocytic thyroiditis is said to be the precursor of thyroid lymphoma, suggesting a role of chronic antigen stimulation in the development of the disease. We present a case of male with lymphocytic thyroiditis who presented with painless progressive neck enlargement and pathology revealed features of high grade lymphoma. Staging and posttreatment 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) was performed. This report reemphasizes the role of 18 F-FDG PET/CT in the diagnosis, staging, and assessment of therapy response in patients with extranodal lymphoma, including the primary thyroid lymphoma

    2007-08-01

    We report the case of a previously healthy, 10-year-old boy who presented to the emergency department with a syncopal episode. In the emergency department, the patient was diagnosed with a right atrial mass, later identified as a precursor B-cell lymphoblastic lymphoma (LL). Most causes of syncope in children are not life threatening. In most cases, it indicates a predisposition to vasovagal episodes. Lymphomas account for approximately 7% of malignancies among children younger than 20 years, are more common in white males and immunocompromised patients, and are predominantly tumors of T-cell origin. Children with non-Hodgkin lymphoma usually present with extranodal disease, most frequently involving the abdomen (31%), mediastinum (26%), or head and neck (29%). Our patient was unique in that he was a nonimmunocompromised, black boy, presenting with syncope in the setting of a large atrial mass identified as a precursor B-cell LL. To our knowledge, there are no reported cases of precursor B-cell LL presenting as syncope and a cardiac mass.

    Mucosa-associated lymphoid tissue lymphomas can occur in various parts of the body, and half of mucosa-associated lymphoid tissue lymphomas occur in the gastrointestinal tract. Gastric mucosa-associated lymphoid tissue lymphoma is the most common lymphoma of the gastrointestinal tract and primary rectal mucosa-associated lymphoid tissue lymphoma is very rare. Because of the high radiosensitivity of mucosa-associated lymphoid tissue lymphomas, this condition can be controlled with radiotherapy of approximately 30 Gy alone. However, ovarian dysfunction as an adverse event of radiotherapy for pelvic lesions can become a problem in girls and women. We report a case of a 28-year-old woman with rectal mucosa-associated lymphoid tissue lymphoma who safely gave birth to a baby following 30.6 Gy radiotherapy to her whole rectum. A 28-year-old Japanese woman became aware of bloody stools and was diagnosed as having Lugano I rectal mucosa-associated lymphoid tissue lymphoma. She was referred to our institute and initiated on radiotherapy. However, she expressed a desire to bear children. We used horizontally opposed pair fields for radiotherapy to minimize the irradiation to her endometrium and ovary. A total dose of 30.6 Gy was given in 17 fractions of 1.8 Gy by 10-Megavolt X-ray linear accelerator. As a result, one-third of her uterus and half of her ovary were outside the irradiation field. After approximately 1 year of treatment, positive pregnancy was confirmed and finally she safely gave birth to a baby girl without congenital abnormalities. This report provides hope for girls and women who have undergone irradiation for pelvic mucosa-associated lymphoid tissue lymphomas and who desire to bear children.

    2010-06-01

    We present a follow-up case report of possible transmission of lymphoma 12 years after deceased-donor renal transplantation from a male donor who was found at autopsy to have had an occult lymphoma. The female recipient underwent prompt transplant nephrectomy. However, 12 years later, she presented with cerebral B cell lymphoma. A donor origin for the cerebral lymphoma was supported by in situ hybridization demonstration of a Y chromosome in the lymphoma. There was a dramatic resolution of the cerebral lesions with tapering of immunosuppression and introduction of rituximab treatment. The finding of a Y chromosome in the cerebral lymphoma does not exclude a host contribution to lymphoma development.

    We review here 3 cases of primary thyroid lymphoma that we experienced during the past 5 years (age range: 39-55, all of the patients were female). The clinical and various ultrasonographic characteristics together with the other imaging modalities of primary thyroid lymphomas are described. The clinical features at presentation for one patient were a goiter with rapid growth and this was accompanied by compressive symptoms. The tumors of the other 2 patients were incidentally found during screening thyroid ultrasound exams. The pathologic studies of 2 cases showed a diffuse B-cell lymphoma with associated Hashimoto's thyroiditis and one case was a B-cell lymphoma of the MALT type. An extra-thyroid extension was shown in one case. The treatments included surgery alone for two cases, and chemotherapy and radiation therapy for one case. A US exam of thyroid lymphoma can show various morphological features, and US-CNB is helpful for diagnosing thyroid lymphoma.

    Introduction: MALT lymphoma arises in a variety of body tissues, but most often in the stomach. Though relatively rare, these MALT lymphomas may arise within several sites in the head and neck, and often present diagnostic and therapeutic challenges. Immunohistochemical analysis are helpful in confirming the diagnosis between the MALT-lymphoma and the reactive lymphoid hyperplasia. MALT-type lymphoma demonstrated characteristic negative staining for CD3, CD5 and CD43, positive staining for CD20, and monotypic staining for either kappa or lambda light chain immunoglobulin markers, whereas reactive lymphoid hyperplasia all expressed Band T cell markers. Material and Methods: 41 cases of nasopharyngeal masses were obtained from the files at pathology department, Mansoura Faculty of Medicine through the period from 2002 till 2006. 31 cases were corresponded histomorphologically to low-grade B-cell lymphoma of mucosa associated lymphoid tissue (MALT) type and 10 patients with reactive lymphoid hyperplasia of the adenoid. Hematoxylin-eosin-stained slides were reviewed to confirm the diagnosis. Immunohistochemical studies were performed on formalin-fixed, paraffin-embedded sections using the labeled streptavidin-biotin-peroxidase complex method with DAB as chromogen. The following antibodies were evaluated CD20, CD3, Kappa, lambda and cytokeratin antibodies. Results: All cases of low grade MALT lymphoma show Iymphoepitheliallesion and proliferation of centrocyte like cells. 14 cases (45.1 %) show subepithelial plasma cells. Dutcher bodies were demonstrated in 10 cases (32.2%). Monocytoid B-cells were seen in 12 cases (38.7%). Six (60%) out of the ten cases of adenoids show transmigrating lymphocyte without formation of lymphoepithelial lesion. All cases with MALT-type lymphoma expressed CD20 and not CD3 whereas 10 cases of adenoid, all expressed Band T cell markers. Immunohistochemical staining showed that 31 cases of low grade MALT lymphoma were positive for immunoglobin

  4. Primary Gallbladder Small Lymphocytic Lymphoma as a Rare Postcholecystectomy Finding

    Full Text Available Introduction. Primary lymphoma of the gallbladder is an extremely rare entity with approximately 50 cases reported so far. In many of these cases the presenting symptoms were mimicking symptomatic gallstone disease and the diagnosis was made postoperatively, especially when the preoperative imaging results were far from suspicious for malignant disease. Patients and Methods. We report a case of primary lymphoma of the gallbladder in an 85-year-old man with gallstone disease, who was admitted for elective cholecystectomy 2 months after an episode of acute cholecystitis and pancreatitis. Histological evaluation of the specimen revealed a small lymphocytic lymphoma of the gallbladder. This type of primary gallbladder lymphoma has not been previously reported. Discussion. The most common primary lymphomas of the gallbladder are MALT lymphomas and diffuse large B-cell lymphomas, although a variety of other histological types have been reported. The association of these lesions with chronic inflammation is the most convincing theory for their pathogenesis. For lesions confined to the gallbladder, cholecystectomy is considered to be sufficient, while supplementary chemotherapy significantly improves prognosis in more advanced disease.

    Primary cutaneous peripheral T-cell lymphomas (PTL), unspecified, are rare lymphomas, with a poor prognosis. They grow and disseminate rapidly, leading to widespread disease. We report a case of PTL, unspecified occurring on the nose. Despite its aggressive histology, this tumour behaved indolently. It is remarkably similar, clinically and histologically, to four recently described cases that occurred on the ear.

    Because of the increasing incidence of primary central nervous system lymphoma (PCNSL), it is essential to recognize this disease in order to start appropriate treatment. We present the characteristic CT and MRI features of this tumour. The findings of 32 CT and 31 MR of 37 immunocompetent patients with biopsy-proved PCNSL are reviewed. The main features are presented and analysed, and are discussed in comparison with proven literature data. Primary central nervous system lymphoma presents as supratentorial solitary lesions in approximately 80% of the patients and multiple lesions in 20%. In contrast to classical data, the lesions are located in deep structures only in one-third of the cases, and involve posterior fossa in 10% of cases. Most of the lesions are hyperdense or isodense (92%) on CT, hypointense or isointense on T1-weighted images, and only about 40% are hyperintense on T2-weighted images. Nearly all the lesions enhance, except after corticosteroid administration. They produce mild oedema and mass effect. Meningeal or ventricular enhancement are rare but suggestive. Calcification, haemorrhage or necrosis are scarce. Although PCNSL in immunocompetent patients have a variable CT and MR appearance, the imaging data often suggest the diagnosis. (orig.)

    Full Text Available Mantle cell lymphoma is a type of no-Hodgkin lymphoma that affects extranodal areas, especially, bone narrow, digestive tract and Waldeyer ring. Here we report a case of mantle cell lymphoma IV Ann Arbor stage with cutaneous lesions on nasal dorsum and gland as the first manifestations. Skin involvement is a very rare manifestation and less than 20 cases have been reported in the literature. The importance of stablishing multidisciplinary relationships for a global approach has been shown by this clinical case.

    Primary breast lymphomas, a rare subtype of non-Hodgkin's lymphoma, represent 0.04 to 0.5% of all breast cancers, 0.38 to 0.7% of all lymphomas, and 1.7 to 2.2% of extranodal lymphomas. The treatment choice is based on chemotherapy containing anthracycline and rituximab. Surgery is limited to being less invasive and only for diagnostic purposes. Radiotherapy has an important role as consolidation therapy, particularly in patients with negative nodes. A 70 year old woman with a breast nodule in the left upper outer quadrant, with slow growth, expansive, painless, and accompanied by skin changes, malaise, weight loss, fatigue, chill, and sweating. There was tissue replacement by the mammary gland tumour, skin changes due to invasion, and a 5cm axillary lymphadenopathy. The mammography showed skin thickening and a dense pattern of 80% of breast tissue replacement, and the lymphadenopathy with loss of radiolucent centre and soft tissue invasion. The biopsy confirmed a diffuse high grade large cell lymphoma. She received an Rituximab (R-CHOP) chemotherapy scheme and radiotherapy with tangential and supraclavicular and axillary fields. After completing the chemotherapy, the patient is on follow-up, and at 15 months she is alive without disease activity. Primary lymphoma of the breast is a rare entity. Multimodal treatment with combined chemo-radiotherapy is the cornerstone. Surgery is reserved only for diagnostic purposes. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Daratumumab (DARA) is a human CD38-specific IgG1 antibody that is in clinical development for the treatment of multiple myeloma (MM). The potential for IgG1 antibodies to induce macrophage-mediated phagocytosis, in combination with the known presence of macrophages in the tumor microenvironment...... in MM and other hematological tumors, led us to investigate the contribution of antibody-dependent, macrophage-mediated phagocytosis to DARA's mechanism of action. Live cell imaging revealed that DARA efficiently induced macrophage-mediated phagocytosis, in which individual macrophages rapidly...... and sequentially engulfed multiple tumor cells. DARA-dependent phagocytosis by mouse and human macrophages was also observed in an in vitro flow cytometry assay, using a range of MM and Burkitt's lymphoma cell lines. Phagocytosis contributed to DARA's anti-tumor activity in vivo, in both a subcutaneous...

    Full Text Available We describe the case of a 13-year-old boy who presented with persistent thrombocytopenia during maintenance chemotherapy with mercaptopurine and methotrexate for T cell lymphoblastic lymphoma. He was diagnosed with immune thrombocytopenia (ITP after thorough investigations for the relapse of lymphoma and was successfully treated with immunoglobulin and steroids. ITP is known to be associated with chronic lymphocytic leukemia, Hodgkin lymphoma, and various types of non-Hodgkin lymphoma but rarely with T cell non-Hodgkin lymphoma or in children. Diagnosis of ITP with lymphoma is challenging due to the many factors affecting platelet counts, and ITP often complicates the diagnosis or treatment course of lymphoma. The underlying mechanism of ITP with NHL is still unclear. Drug-induced immunomodulation with a reduction of regulatory T cells might have contributed to the development of ITP in our case.

    Full Text Available We present an unusual case of a metastatic mantle cell lymphoma (MCL to the pituitary gland. The patient had a known history of MCL for which she previously received chemotherapy. She presented with new-onset diplopia and confusion, and reported a history of progressive vision blurriness associated with headache, nausea, and vomiting. MRI of the brain showed an enhancing lesion within the sella turcica involving the cavernous sinuses bilaterally, extending into Meckel's cave on the left, and abutting the optic nerves bilaterally. Following surgical excision, histopathology revealed the tumor to be a MCL. Metastatic pituitary tumors are rare and have been estimated to make up 1% of tumors discovered in the sellar region. The two most common secondary metastatic lesions to the sella are breast and lung carcinoma followed by prostate, renal cell, and gastrointestinal carcinoma. Metastatic lymphoma to the pituitary gland is especially rare and is estimated to constitute 0.5% of all metastatic tumors to the sella turcica. To our knowledge, this is the first reported case of MCL metastasizing to the pituitary gland.

    Plasmablastic lymphoma is a non-Hodgkin lymphoma characterized by its plasmacytic differentiation and predilection for the oral cavity. It is among the lymphomas most commonly associated with AIDS. This report details a case of a HIV-positive patient with a 1-month history of an exophytic mass in the gingival area of the upper left quadrant. The diagnosis of plasmablastic lymphoma was made based on its histopathological and immunophenotypical features. She was treated with chemotherapy followed by autologous hematopoietic stem cell transplantation. Despite complete resolution of the lesion, the patient died of cardiorespiratory arrest. This case illustrates plasmablastic lymphoma as the first clinical manifestation of AIDS, highlighting the importance of differentiating between a potentially malignant lesion and other pathologic processes.

    Full Text Available Primary hepatic marginal zone B-cell malignant lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma is extremely rare. We present a case in which a lesion was diagnosed as 2 contiguous tumors (MALT lymphoma and hemangioma using contrast-enhanced ultrasonography (US with sonazoid. There has been no previous case of contiguous hepatic MALT lymphoma and hemangioma. The present case was a female with no medical history. We detected a snowman-like appearance, which was a tumor of 15 mm in diameter with hypo- and hyper-echogenicities in the lateral and medial parts, respectively, in the Couinaud's segment (S6 of the liver on US. The tumor appeared as a single lesion with a low-density area in the unenhanced phase and prolonged enhancement in the equilibrium phases on dynamic CT. On MRI, the whole lesion showed a low-intensity signal on T1-weighted imaging, but isointensity in the lateral part and high intensity in the medial part were seen on T2-weighted imaging. On contrast-enhanced US, the lateral hypoechoic region was homogenously hyperenhanced in the early vascular phase, and the contrast medium was washed out after about 30 s; in contrast, the medial hyperechoic region was gradually stained from the margin toward the central region. The tumor showed a defect in both hypo- and hyperechoic regions in the postvascular phase. Hemangioma was suspected for the medial part based on the typical image findings, but the lateral part was not given a diagnosis. Thus, surgical resection was performed. The medial part was a hemangioma, and the lateral part was a MALT lymphoma by histopathological findings.

    Full Text Available Plasmablastic lymphoma (PBL is an aggressive non-Hodgkin lymphoma classically occurring in individuals infected with human immunodeficiency virus (HIV. It has a predilection for the oral cavity and jaw. However, recent case reports have shown this variety of lymphoma in the stomach, lung, nasal cavity, cervical lymph nodes and jejunum in HIV-negative individuals. In this manuscript we report a case of primary PBL of brain in an HIV-negative heterosexual man, who presented with multiple episodes of seizures and hemiparesis. It proved a diagnostic challenge as initial stereotactic brain biopsy showed only few necrotic fragments and possibility of glioblastoma multiforme was rendered. Later patient underwent craniotomy and subsequent histopathology combined with immunohistochemistry led us in making a correct diagnosis of extramedullary PBL. Extensive systemic work up failed to reveal any disease outside the central nervous system. Only single case of primary PBL of brain in HIV-negative individual has been reported until date. To the best of our knowledge, this is the second report to suggest such an association.

    Full Text Available Abstract Introduction Many cancers are associated with inferior vena cava (IVC obstruction, but very few cancers have the ability to propagate within the lumen of the renal vein or the IVC. Renal cell carcinoma is the most common of these cancers. Renal cancer with IVC extension has a high rate of recurrence and a low five year survival rate. Case presentation A 62-year-old Caucasian woman previously in good health developed the sudden onset of severe reflux symptoms and right-sided abdominal pain that radiated around the right flank. A subsequent ultrasound and CT scan revealed a right upper pole renal mass with invasion of the right adrenal gland, liver, left renal vein and IVC. This appeared to be consistent with stage III renal cancer with IVC extension. Metastatic nodules were believed to be present in the right pericardial region; the superficial anterior abdominal wall; the left perirenal, abdominal and pelvic regions; and the left adrenal gland. The pattern of these metastases, as well as the invasion of the liver by the tumor, was thought to be atypical of renal cancer. A needle biopsy of a superficial abdominal wall mass revealed a surprising finding: The malignant cells were diagnostic of large-cell, B-cell non-Hodgkin's lymphoma. The lymphoma responded dramatically to systemic chemotherapy, which avoided the need for nephrectomy. Conclusion Lymphomas only rarely progress via intraluminal vascular extension. We have been able to identify only one other case report of renal lymphoma with renal vein and IVC extension. While renal cancer would have been treated with radical nephrectomy and tumor embolectomy, large-cell B-cell lymphomas are treated primarily with chemotherapy, and nephrectomy would have been detrimental. It is important to remember that, rarely, other types of cancer arise from the kidney which are not derived from the renal tubular epithelium. These may be suspected if an atypical pattern of metastases or unusual

    Full Text Available Introduction. Intussusception is a rare cause of bowel obstruction in adults and is usually associated with an underlying pathology, benign, or malignant. This is a report of a case of jejunojejunal intussusception secondary to non-Hodgkin’s B-cell lymphoma in an adult patient. Case Presentation. A 74-year-old male with no previous significant medical history presented with symptoms of acute intestinal obstruction. A CT scan of the abdomen and pelvis revealed 2 areas of jejunojejunal intussusception, which were surgically managed successfully. Histopathological examination of the specimen revealed the presence of high grade diffuse large B-cell-type non-Hodgkin’s lymphoma, and the patient was referred to the oncology team for further management. Discussion. B-cell lymphoma is a rare but well-documented cause of intussusception in adults, with most cases being at the ileocolic region. We present a rare case of jejunojejunal intussusception as the initial presentation of non-Hodgkin’s B-cell lymphoma in an adult patient.

    Full Text Available We report a rare case of diffuse large B-cell lymphoma (DLBCL of the lacrimal sac in a 50-year-old male. The incidence of primary ocular lymphoma is low and it is considered a rare disease. Moreover, reports of ocular DLBCL are uncommon and the disease remains poorly characterized. Our patient presented for management of osteomyelitis and was incidentally found to have a painless swelling and cyst around his right eye. A PET/CT scan revealed hypermetabolic activity within the lacrimal sac and a subsequent excisional biopsy of the mass yielded histopathology consistent with DLBCL. Consequently, the patient underwent treatment with R-CHOP therapy. The patient responded well to chemotherapy with a substantial shrinkage in tumor burden and the disease remained localized. Herein, we present a rare case of primary ocular lymphoma, highlight the importance of early diagnosis, and review current treatment modalities.

    Nodal marginal zone lymphoma (NMZL) represents a rare and heterogeneous group that lacks markers specific for the diagnosis. We evaluated morphologic and immunoarchitectural features of 51 NMZLs, and the following immunostains were performed: CD20, CD21, CD23, CD5, CD3, CD43, CD10, Ki-67, BCL1, BCL2, BCL6, HGAL, and LMO2. Four immunoarchitectural patterns were evident: diffuse (38 [75%]), well-formed nodular/follicular (5 [10%]), interfollicular (7 [14%]), and perifollicular (1 [2%]). Additional features included a monocytoid component (36 [71%]), admixed large cells (20 [39%]), plasma cells (24 [47%]), compartmentalizing stromal sclerosis (13 [25%]), and prominent blood vessel sclerosis (10 [20%]). CD21 highlighted disrupted follicular dendritic cell meshwork in 35 (71%) of 49 cases, and CD43 coexpression was present in 10 (24%) of 42 cases. A panel of germinal center-associated markers was helpful in eliminating cases of diffuse follicle center lymphoma. Our results highlight the histologic and immunoarchitectural spectrum of NMZL and the usefulness of immunohistochemical analysis for CD43, CD23, CD21, BCL6, HGAL, and LMO2 in the diagnosis of NMZL.

    Primary cutaneous lymphomas are uncommon. This article describes the Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV) and reports on the results from the first year. Disease registry for patients with primary cutaneous lymphoma. The participating hospitals prospectively recorded data on diagnosis, treatment, tests, and disease stage for all patients with primary cutaneous lymphoma. A descriptive analysis was performed. In December 2017, the registry contained data on 639 patients (60% male) from 16 university hospitals. The most common diagnoses, in order of frequency, were mycosis fungoides/Sézary syndrome (MF/SS) (348 cases, 55%), primary cutaneous B-cell lymphoma (CBCL) (184 cases, 29%), primary cutaneous CD30 + T-cell lymphoproliferative disorder (CD30 + CLPD) (70 cases, 11%), and other types of T-cell lymphoma (37 cases, 5%). In total, 105 (16.5%) of the cases recorded were incident cases. The most common diagnosis in the MF/SS group was classic MF (77.3%). Half of the patients with MF had stage IA disease when diagnosed, and the majority were either in partial remission (32.5%) or had stable disease (33.1%). The most widely used treatments were topical corticosteroids (90.8%) and phototherapy. The most common form of primary CBCL was marginal zone lymphoma (50%). Almost all of the patients had cutaneous involvement only and nearly half had stage T1a disease. Most (76.1%) were in complete remission. The main treatments were surgery (55.4%) and radiotherapy (41.9%). The most common diagnosis in patients with CD30 + CLPD was lymphomatoid papulosis (68.8%). Most of the patients (31.4%) had stage T3b disease and half were in complete remission. The most common treatments were topical corticosteroids (68.8%) and systemic chemotherapy (32.9%). The characteristics of patients with primary cutaneous lymphoma in Spain do not differ from those described in other series in the literature. The registry will facilitate

    AIMS: Gastric MALT (mucosa-associated lymphoid tissue) lymphoma is now recognized as a distinct entity within extranodal non-Hodgkin's lymphoma. The purpose of this study was to describe the radiographic findings in low grade gastric MALT lymphoma. MATERIALS AND METHODS: We retrospectively reviewed the radiographic findings in 22 cases of low-grade gastric MALT lymphoma. The study group consisted of 15 men and seven women (median age 68 years, range 41-91 years). Lesions were designated as infiltrative or polypoid by consensus of two radiologists. Polypoid lesions were categorized by number and size. Anatomical site within the stomach and presence of transpyloric or oesophagogastric extension was determined for each case. The presence of abdominal lymphadenopathy was categorized as regional or distant. The presence of Helicobacter pylori was determined from endoscopic and surgical biopsies. RESULTS: Computed tomography (CT) revealed abnormalities of the stomach in 19 cases of the 21 in which it was performed. There were 14 infiltrative lesions and five polypoid lesions. Of the 14 infiltrative lesions, the mean gastric wall thickness was 2.2 cm (range 0.8-6.0 cm). There were three single and two multiple polypoid lesions (mean size 2.2 cm, range 1.5-2.7 cm). Transpyloric extension was observed in two cases and oesophagogastric extension in one. Abdominal lymphadenopathy was observed in 10 of 21 patients. Helicobacter pylori was found in 19 of 22 cases (86%). CONCLUSION: Low grade B cell gastric MALT lymphomas present with an infiltrative form on CT in about three-quarters of cases and a polypoid pattern in the remainder. Abdominal lymphadenopathy is seen in approximately one-half of cases. There is a high association with Helicobacter pylori. Brown, J.A. 2000. Clinical Radiology 55, 384-389

    Full Text Available Primary thyroid lymphoma is a rare malignancy, representing 2-8% of all thyroid malignancies and 1-2% of all extranodal lymphomas. The majority of cases concern non-Hodgkin`s lymphoma of B cell origin, following by Hodgkin’s disease, T cell lymphomas and rarely marginal zone B-cell mucosa-associated lymphoid tissue (MALT lymphomas. MALT lymphomas have been associated with long-standing autoimmune Hashimoto`s thyroiditis. We present the case of a 44-years-old woman with thyroid MALT lymphoma in the background of multinodular goiter of autoimmune origin.

    Full Text Available Background: Malignant lymphomas arising in extranodal sites are intriguing. The histological types of lymphomas vary from one site to another. This study is undertaken to diagnose and categorize extranodal lymphomas using histochemistry and immunohistochemistry (IHC. Materials and Methods: Formalin processed paraffin blocks and hematoxylin and eosin stained sections were used for routine histology. IHC was done in all cases. Results: We have encountered 31 cases of extra nodal lymphomas over a period of 3 years. The tumors occurred at different sites, including brain, nasopharynx, nose, gastrointestinal tract, thyroid, bone, testis, breast, lung, vagina, and skin. Majority of the cases were B-cell lymphomas, while four cases were T-cell lymphomas. Among the B-cell lymphomas diffuse large B-cell lymphoma was the most common variant. Conclusion: This study reiterates the key role of IHC particularly when the differential diagnosis includes an undifferentiated epithelial malignancy and a high-grade lymphoma in the extranodal sites as the treatment modalities and prognosis are different.

    Primary cutaneous follicle center lymphoma is an indolent primary cutaneous B-cell lymphoma originating from the follicle center cells, composed of a combination of centrocytes (small and large cleaved cells) and centroblasts (large noncleaved cells) with a follicular, follicular/diffuse, or diffuse growth pattern. Lesions are mostly located on the head, neck and trunk. A case is presented of a 56-year-old male patient with primary cutaneous follicle center lymphoma, with lesions involving the skin of the back, shoulders, presternal area and right forearm. As the patient presented a disseminated cutaneous form of the disease that involved several anatomical regions, complete work-up was followed by superficial fractionated radiotherapy of eight fields in VI expositions, with total irradiation dose of 1400 cGy upon the following fields: right and left pectoral region, left and right shoulders, right suprascapular region, and proximal third of the right forearm. Total irradiation dose applied upon each field for the lesions located on the left and right side of the back was 1500 cGy. This therapy resulted in significant reduction of visible tumor. The patient was regularly followed up on outpatient basis for 12 months of radiotherapy, being free from local recurrence and systemic spread of the disease

    BACKGROUND: Primary lymphoma of the breast accounts for 0.04-0.5% of all breast malignancies and approximately 1% of all extranodal lymphomas. For stage IE node-negative disease, involved field radiotherapy is recommended except for very young women in whom the risk of breast cancer is a concern. The rate of complete response for limited stage extranodal marginal B-cell lymphoma is in excess of 90%. CASE REPORT: We report the case of a 62-year-old lady who presented with a unilateral painless palpable right breast lump. She subsequently underwent a trucut biopsy of the lesion. The histology revealed a low-grade B-cell non-Hodgkin\\'s lymphoma (NHL). Immunohistochemistry showed that more than 95% of the cells were B cells which were CD 20+\\/CD 45+ and BC L6+. This confirmed the diagnosis of marginal zone lymphoma. Staging work-up was negative for distant metastases. Serum alkaline phosphatase and lactate dehydrogenase were normal. The patient had no \\'B\\' symptoms. Her final diagnosis was clinical stage IAE NHL, and she was referred for curative radiotherapy. CONCLUSION: Radiation treatment is a safe and extremely effective modality of treatment for early stage I marginal zone B-cell lymphomas of the breast.

    Full Text Available Celiac disease is the most common chronic gastroenterological autoimmune disease characterized by gluten intolerance. The diagnosis of celiac disease and enteropathy-associated T cell lymphoma is often made when it is too late.Case report describes a 35-year-old female patient managed for one year under the diagnosis of inflammatory bowel disease and admitted to our hospital for exacerbation of the underlying disease. However, inflammatory bowel disease was ruled out by diagnostic work-up, while the clinical picture and the findings obtained raised suspicion of lymphoma. The patient’s condition was additionally complicated by fulminant course of the disease and ileus.Conclusion:Early diagnosis and appropriate treatment of the disease, and follow up of family members are crucial to prevent intestinal lymphoma development.

    The case is reported of a 55-year-old man with diffuse malignant lymphoma type B associated with transient optic chiasm infiltration and visual disturbances but with persistent hypopituitarism, hyperprolactinaemia and diabetes insipidus. The patient was administered chemotherapy and radiotherapy. Repeated MR and CT scans showed optic chiasm infiltration, which disappeared in the course of the chemotherapy but then recurred, changed its appearance and finally disappeared again. In the meantime visual disturbances occurred and disappeared during the therapy. Hypopituitarism, diabetes insipidus and hyperprolactinaemia were diagnosed and replacement therapy was administered. Later on abdominal pain occurred, and a CT scan revealed bilateral kidney masses and enlarged retroperitoneal lymph nodes. These were diffuse malignant lymphoma with regional lymphonodulitis in histology. Finally, hydrothorax and hydroretroperitoneum were diagnosed. The patient died as a result of systemic complications of the disease. The length of survival time documented following the hypothalamochiasmatic infiltration and diagnosis of lymphoma makes the case an unusual one for patients with CNS lymphoma. Hormonal disturbances accompanying the suprasellar region infiltration are very important from the practical point of view. (author)

  15. Lifetime physical inactivity is associated with increased risk for Hodgkin and non-Hodgkin lymphoma: A case-control study.

    Although physical activity is a well-established risk factor for several cancer types, studies evaluating its association with lymphoma have yielded inconclusive results. In such cases where physical activity is not clearly associated with cancer risk in a dose-dependent manner, investigators have begun examining physical inactivity as an independent exposure of interest. Associations of self-reported, lifetime physical inactivity with risk of developing Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) were evaluated in a hospital-based case control study using data from the Patient Epidemiology Data System at Roswell Park Comprehensive Cancer Center. Participants included 87 patients with HL and 236 patients with NHL as well as 348 and 952 cancer-free controls, respectively. Multivariable-adjusted logistic regression models were fit to calculate odds ratios (OR) and 95% confidence intervals (CI) estimating the association between physical inactivity and lymphoma risk. We observed significant, positive associations between lifetime recreational physical inactivity and risk of both HL (OR = 1.90, 95% CI: 1.15-3.15) and NHL (OR = 1.35, 95% CI: 1.01-1.82). The current analysis provides evidence for a positive association between physical inactivity and risk of both HL and NHL. These results add to a growing body of research suggesting that lifetime physical inactivity may be an important independent, modifiable behavioral risk factor for cancer.

    The treatment of non-Hodgkin lymphomas (NHL) is discussed. The use of radiotherapy, chemotherapy or both in a combined therapy is studied considering several aspects as age of the patients (adults vs children), size and extension of the lymphoma, stage of the disease. It is mentioned that more advanced cases and those with more aggressive histology need combined modality treatments or even just chemotherapy. (M.A.C.)

    Full Text Available Cancer may be induced by many environmental and physiological conditions. Infections with viruses, bacteria and parasites have been recognized for years to be associated with human carcinogenicity. Here we review current concepts of carcinogenicity and its associations with parasitic infections. The helminth diseases schistosomiasis, opisthorchiasis, and clonorchiasis are highly carcinogenic while the protozoan Trypanosoma cruzi, the causing agent of Chagas disease, has a dual role in the development of cancer, including both carcinogenic and anticancer properties. Although malaria per se does not appear to be causative in carcinogenesis, it is strongly associated with the occurrence of endemic Burkitt lymphoma in areas holoendemic for malaria. The initiation of Plasmodium falciparum related endemic Burkitt lymphoma requires additional transforming events induced by the Epstein-Barr virus. Observations suggest that Strongyloides stercoralis may be a relevant co-factor in HTLV-1-related T cell lymphomas. This review provides an overview of the mechanisms of parasitic infection-induced carcinogenicity.

    Full Text Available Abstract In the following report we discuss a very rare case of malignant T-cell lymphoma of the thyroid gland that developed in a 70-year-old woman with a past history of hypothyroidism due to chronic thyroiditis. The chief complaint was a rapidly growing neck mass. CT and ultrasonographic examination revealed a diffuse large thyroid gland without a nodule extending up to 13 cm. Although presence of abnormal lymphoid cells in the peripheral blood was not found, the sIL-2 Receptor antibody and thyroglobulin measured as high as 970 U/ml and 600 ng/mL respectively. Fine needle aspiration cytology diagnosed chronic thyroiditis. A preoperative diagnosis of suspicious malignant lymphoma of the thyroid gland accompanied by Hashimoto’s thyroiditis was made, and a right hemithyroidectomy was performed to definite diagnosis. Histological examination revealed diffuse small lymphocytic infiltration in the thyroid gland associated with Hashimoto’s thyroiditis. Immunohistochemical examination showed that the small lymphocytes were positive for T-cell markers with CD3 and CD45RO. The pathological diagnosis was chronic thyroiditis with atypical lymphocytes infiltration. However, Southern blot analysis of tumor specimens revealed only a monoclonal T-cell receptor gene rearrangement. Finally, peripheral T cell lymphoma was diagnosed. Therefore, the left hemithyroidectomy was also performed one month later. No adjuvant therapy was performed due to the tumor stage and its subtype. The patient is well with no recurrence or metastasis 22 months after the surgical removal of the thyroid. As malignant T-cell lymphoma of the thyroid gland with Hashimoto’s thyroiditis was difficult to diagnose, gene rearrangement examination needed to be performed concurrently.

    Full Text Available Pneumocystis pneumonia (PCP is a life-threatening opportunistic infection that sometimes occurs in immunocompromised patients with human immunodeficiency virus (HIV. Here, we report two extremely rare cases of PCP in non-HIV pregnant women who underwent chemotherapy for malignant lymphoma. Case  1 is a 34-year-old primigravida who was diagnosed with Hodgkin’s lymphoma. She received ABVD chemotherapy and developed PCP at 37 weeks of gestation. After the onset of PCP, emergent cesarean section was performed due to a nonreassuring fetal status. Case  2 is a 31-year-old multigravida with diffuse large B-cell lymphoma who was administered R-CHOP chemotherapy. At 34 weeks of gestation, she complained of dyspnea and developed PCP. She delivered her baby vaginally immediately after the onset of symptoms. Both patients were treated with sulfamethoxazole-trimethoprim (ST and recovered shortly thereafter. The babies’ courses were also uneventful. PCP remains a serious cause of death, especially in non-HIV patients, and, therefore, appropriate prophylaxis and a prompt diagnosis are imperative.

    Full Text Available Lymphoid infiltrates of the salivary gland can be either reactive or neoplastic. The reactive lesion, lymphoepithelial sialadenitis (LESA may be associated with Sjogren′s syndrome (SS or may occur as an isolated salivary gland enlargement. Patients with LESA/SS have a particularly high risk of subsequently developing lymphoma, which is a low-grade mucosa-associated lymphoid tissue (MALT type lymphoma of the salivary gland. We document a rare case of primary non-Hodgkin′s lymphoma of the parotid gland arising in the background of LESA and with a rare example of transformation from low grade to high-grade B cell lymphoma of MALT type.

    Lymphomas are classified based on the normal counterpart, or cell of origin, from which they arise. Because lymphocytes have physiologic immune functions that vary both by lineage and by stage of differentiation, the classification of lymphomas arising from these normal lymphoid populations is complex. Recent genomic data have contributed additional complexity. Areas covered: Lymphoma classification follows the World Health Organization (WHO) system, which reflects international consensus and is based on pathological, genetic, and clinical factors. A 2016 revision to the WHO classification of lymphoid neoplasms recently was reported. The present review focuses on B-cell non-Hodgkin lymphomas, the most common group of lymphomas, and summarizes recent changes most relevant to hematologists and other clinicians who care for lymphoma patients. Expert commentary: Lymphoma classification is a continually evolving field that needs to be responsive to new clinical, pathological, and molecular understanding of lymphoid neoplasia. Among the entities covered in this review, the 2016 revision of the WHO classification particularly impact the subclassification and genetic stratification of diffuse large B-cell lymphoma and high-grade B-cell lymphomas, and reflect evolving criteria and nomenclature for indolent B-cell lymphomas and lymphoproliferative disorders.

    To describe the characteristics of CT findings in nasal lymphoma. We retrospectively reviewed CT findings and pathologic findings of eight patients (six males and two females) aged between 24 and 68 years with pathologically-proven nasal lymphoma. We analyzed mass location, laterality, size, margin, mass effect, adjacent bony change and contrast enhancement pattern. All eight cases were non-Hodgkin's lymphoma, intermediate grade, diffuse large cell type. Seven cases were B-cell type and one was T-cell. In all cases, tumors were located in the medial wall of the inferior turbinate. In four cases, they were also found in the anterior ethmoidal sinus, and in one case, in the nasal septum. The mean size of the main mass was 3.3cm. In seven cases, tumors were unilateral (one on the right; six on the left), and in the remaining case, bilateral. In six cases tumor margin was smooth and in two cases focal nodularity was seen. In two cases there was no bony change, and in four, there was mucosal thickening along the nasal septum; in one of these four, minimal bony erosion was also found. In the other two cases, bony destruction was seen, and tumors were very large(7cm in diameter) or bilterally located. In three cases, the nasal septum was displaced by the mass. In all cases with bony change, the nasal septum was involved. All tumors were homogeneously well enhanced after IV contrast administration. The main CT findings of nasal non-Hodgkin's lymphoma were smooth margin, unilateral location (mainly in the medial wall of the inferior turbinate and growing to the medial side without bony destruction) mucosal thickening along the nasal septum and clear homogeneous enhancement after IV contrast administration. These characteristics will help diagnosis, help deter-mine the appropriate region for radiation and other appropriate therapy, and facilitate prognosis in patients with nasal non-Hodgkin's lymphoma.

    Intraoral presentation of follicular lymphoma is rare, and only three cases in the palate have been reported to date. The present case report describes an uncommon case of follicular lymphoma affecting the palate. The clinical aspect was similar to salivary gland neoplasm, and an incisional biopsy was important to establish the correct diagnosis and consequently to plan the treatment. Also discussed is the differential diagnosis among follicular lymphoma, mucosa-associated lymphoid tissue lymphoma, and follicular lymphoid hyperplasia with regard to the histopathologic and immunohistochemical features.

    Childhood (0-14 years) lymphomas, nowadays, present a highly curable malignancy compared with other types of cancer. We used readily available cancer registration data to assess mortality and survival disparities among children residing in Southern-Eastern European (SEE) countries and those in the United States. Average age-standardized mortality rates and time trends of Hodgkin (HL) and non-Hodgkin (NHL; including Burkitt [BL]) lymphomas in 14 SEE cancer registries (1990-2014) and the Surveillance, Epidemiology, and End Results Program (SEER, United States; 1990-2012) were calculated. Survival patterns in a total of 8918 cases distinguishing also BL were assessed through Kaplan-Meier curves and multivariate Cox regression models. Variable, rather decreasing, mortality trends were noted among SEE. Rates were overall higher than that in SEER (1.02/10 6 ), which presented a sizeable (-4.8%, P = .0001) annual change. Additionally, remarkable survival improvements were manifested in SEER (10 years: 96%, 86%, and 90% for HL, NHL, and BL, respectively), whereas diverse, still lower, rates were noted in SEE. Non-HL was associated with a poorer outcome and an amphi-directional age-specific pattern; specifically, prognosis was inferior in children younger than 5 years than in those who are 10 to 14 years old from SEE (hazard ratio 1.58, 95% confidence interval 1.28-1.96) and superior in children who are 5 to 9 years old from SEER/United States (hazard ratio 0.63, 95% confidence interval 0.46-0.88) than in those who are 10 to 14 years old. In conclusion, higher SEE lymphoma mortality rates than those in SEER, but overall decreasing trends, were found. Despite significant survival gains among developed countries, there are still substantial geographic, disease subtype-specific, and age-specific outcome disparities pointing to persisting gaps in the implementation of new treatment modalities and indicating further research needs.

    We present the case of a previously healthy 62 year old man who developed primary non-Hodgkin lymphoma of the liver. Biopsy confirmed that it was a diffuse large anaplastic T-cell lymphoma of an extremely rare type. The diagnosis of this type of lesions is suggested by the presence of a hepatic mass without lymphadenopathy, splenomegaly or bone marrow involvement associated with normal tumor markers (carcinoembryonic antigen, alpha-fetoprotein and CA 19-9 levels). Histological examination of tissue is essential to confirm the diagnosis. Treatment options are surgical resection and/or chemotherapy but the rate of response to treatment varies widely. Some patients can achieve prolonged remission.

    Hydroa vacciniforme-like lymphoma (HVL) is a rare cutaneous T-cell lymphoma that is usually seen in children of Hispanic or Asian origin. Association between chronic latent Epstein-Barr virus infection in both hydroa vacciniforme (HV) and HVL has been demonstrated and has recently been categorized by the World Health Organization as one of the Epstein Barr virus-positive lymphoproliferative disorders of childhood. Patients with HVL present with a cutaneous rash characterized by edema, blisters, ulcers, and scars mainly seen on the face and extremities that mimic HV; however, unlike in HV, the lesions tend to be extensive and deeper and are associated with severe scarring, necrosis, and systemic manifestations. We are reporting 7 cases of an unusual clinical variant of HVL with primarily periorbital edema. All of our patients in this series presented with progressive periorbital edema that was accompanied with systemic symptoms including fever, malaise, and lymphadenopathy. Most cases were initially misinterpreted as inflammatory processes including cellulitis, arthropod bite reactions, and periorbital lupus erythematosus. The biopsy of these lesions revealed an atypical lymphocytic infiltrate predominantly distributed in the deep dermis and in subcutaneous fat. Immunohistochemistry studies revealed a cytotoxic T-cell (CD8) profile. All cases were associated with Epstein-Barr virus infection. Our study presents a rare clinical variant of HVL with predominant periorbital edema. This variant could potentially be overlooked and misdiagnosed as an inflammatory condition; thus, it needs to be included in the differential diagnosis of periorbital edema in young patients.

    Pediatric Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphoma (EBV+ DLBCL) is a rare disease in nonimmunocompromised hosts. In a review of 231 cases of malignant lymphoma (87 Hodgkin lymphoma and 144 non-Hodgkin lymphoma) occurring in Iraqi children, 7 cases (5% of NHLs) were classified as EBV+ DLBCL. Six children presented with nodal disease, and 1 presented with extranodal localization (bone). In all cases, the disease was at an advanced clinical stage (III/IV). Evidence of immunodeficiency (Evans syndrome and selective IgA deficiency) was observed in a single case. Two cases were "monomorphic" with immunoblastic histology, and 5 cases were "polymorphic" with histologic aspects reminiscent of nodular lymphocyte-predominant Hodgkin lymphoma (2 cases) and of CD30+ classical Hodgkin lymphoma (3 cases). In all cases, tumor cells were EBV infected (EBER+/LMP-1+), were medium-large B-cells (CD20+/CD79a+/PAX-5+/BOB-1+/OCT-2+) of non-germinal center (non-GC) origin (CD10-/MUM-1+), and had high proliferative activity (50%-70%). Chromosomal translocations involving BCL2, MYC, and IGH genes were not observed. IGH monoclonality could be demonstrated in 3 of 3 investigated cases. Six cases of EBV-negative DLBCL (4% of NHL) were present in the same series. All had monomorphic histology with centroblastic/immunoblastic morphology; 3 cases were of GC type and 3 of non-GC type. Our findings indicate that in Iraq, DLBCLs are 9% of NHLs. Moreover, 2 different types of the disease do exist; the EBV-positive cases, with strong histologic and immunohistochemical resemblance with EBV+ DLBCL of the elderly, and the EBV-negative cases, which are similar to the pediatric DLBCL usually observed in Western populations.

    Full Text Available Protein losing enteropathy (PLE refers to excessive intestinal protein loss, resulting in hypoalbuminemia. Underlying pathologies include conditions leading to either reduced intestinal barrier or lymphatic congestion. We describe the case of a patient with long-lasting diffuse abdominal problems and PLE. Repetitive endoscopies were normal with only minimal lymphangiectasia in biopsies. Further evaluations revealed an indolent marginal zone lymphoma with minor bone marrow infiltration. Monotherapy with rituximab decreased bone marrow infiltration of the lymphoma but did not relieve PLE. Additional treatments with steroids, octreotide, a diet devoid of long-chain fatty-acids, and parenteral nutrition did not prevent further clinical deterioration with marked weight loss (23 kg, further reduction in albumin concentrations (nadir 8 g/L, and a pronounced drop in performance status. Finally, immunochemotherapy with rituximab and bendamustine resulted in hematological remission and remarkable clinical improvement. 18 months after therapy the patient remains free of gastrointestinal complaints and has regained his body weight with normal albumin levels. We demonstrate a case of PLE secondary to indolent marginal zone lymphoma. No intestinal pathologies were detected, contrasting a severe and almost lethal clinical course. Immunochemotherapy relieved lymphoma and PLE, suggesting that a high suspicion of lymphoma is warranted in otherwise unexplained cases of PLE.

    A 65-year old patient, with no medical history, was admitted for lower gastrointestinal bleeding. On clinical examination the patient seemed to be in good health. However the examination was completed with a rectosigmoidoscopy revealing the presence of mucosal erosions, ulcerations, multiple papulae. The histopathological examination raised the suspicion of a colonic lymphoma. Gastric biopsies suggested a gastric MALT type lymphoma associated to the colonic lymphoma, but the immunohistochemical profile corresponded to a mantle cell lymphoma. In spite of the general poor prognosis of mantle cell lymphoma, our patient had a good clinical and endoscopic response to the standard cyclophosphamide, vincristine, prednisone (CVP) therapy. The cases of gastric and colonic mantle lymphoma are rare, the response to therapy is poor; fortunately, our patient had a complete resolution after completion of the six cycles of chemotherapy.

    Full Text Available Portal hypertension commonly arises in the setting of advanced liver cirrhosis and is the consequence of increased resistance within the portal vasculature. Less commonly, left-sided noncirrhotic portal hypertension can develop in a patient secondary to isolated obstruction of the splenic vein. We present a rare case of left-sided portal hypertension and isolated gastric varices in a patient with large B-cell lymphoma, who was treated with splenic artery embolization. The patient is a 73-year-old male with no previous history of liver disease, who presented with coffee ground emesis and melena. On admission to hospital, he was found to have a hemoglobin level of 3.4 g/l. Emergent esophagogastroduodenoscopy showed isolated bleeding gastric varices (IGV1 by Sarin classification in the fundus and cardia with subsequent argon plasma coagulation injection. He was transferred to our tertiary center where work-up revealed normal liver function tests, and abdominal ultrasound showed patent hepatic/portal vasculature without cirrhosis. MRI demonstrated a large heterogeneously enhancing mass in the pancreatic tail, with invasion into the spleen and associated splenic vein thrombosis. Surgery consultation was obtained, but urgent splenectomy was not recommended. The patient instead underwent splenic artery embolization to prevent future bleeding from his known gastric varices. Pathology from a CT-guided biopsy was consistent with diffuse large B-cell lymphoma. PET imaging showed uptake in the splenic hilum/pancreatic tail region with no additional metastatic involvement. He was evaluated by the Hematology Department to initiate R-CHOP chemotherapy. During his outpatient follow-up, he reported no further episodes of melena or hematemesis. To the best of our knowledge, there have only been two published case reports of large B-cell lymphoma causing upper gastrointestinal bleeding from isolated gastric varices. These cases were treated with splenectomy or

    Full Text Available Helicobacter pylori-related extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue is a paradigm for malignancy arising in an inflammatory background. While the diagnosis of H. pylori gastritis is often straightforward, distinction between severe gastritis and early lymphoma can be difficult and requires careful assessment of clinical findings in addition to histological features and immunohistochemical results. A number of cytogenetic abnormalities have been discovered in H. pylori-related lymphomas and several have clinical importance, related to the responsiveness of lymphoma to H. pylori eradication therapy, but routine molecular studies are not widely utilized. While molecular methods may be used in equivocal cases, a trial of conservative therapy is warranted given the propensity for these lymphomas to regress with eradication of the organism. Once therapy is initiated, care must be taken to avoid a premature assignment of disease refractoriness because complete response can take several months to more than a year. Cases truly refractory to H. pylori eradication therapy may be treated with adjuvant chemoradiation with a high response rate.

    Lymphoma of the cervix is a rare disease. About 1.0% to 1.5% of extranodal lymphomas originates in the female genital tract. The clinical presentation of this condition is nonspecific and magnetic resonance imaging is important for diagnostic elucidation. The present report describes the case of a 80-year-old patient with lumbar pain, whose magnetic resonance imaging showed a large uterine mass. The final diagnosis was lymphoma. (author)

    Acute liver failure (ALF) is a medical emergency requiring immediate evaluation for liver transplantation. We describe an unusual case of a patient who presented with ascites, jaundice, and encephalopathy and was found to have ALF due to natural killer (NK)-like T cell leukemia/lymphoma. The key immunophenotype was CD2+, CD3+, CD7+, CD56+. This diagnosis, which was based on findings in the peripheral blood and ascitic fluid, was confirmed with liver biopsy, and was a contraindication to liver transplantation. A review of the literature shows that hematologic malignancies are an uncommon cause of fulminant hepatic failure, and that NK-like T-cell leukemia/lymphoma is a relatively recently recognized entity which is characteristically CD3+ and CD56+. This case demonstrates that liver biopsy is essential in diagnosing unusual causes of acute liver failure, and that infiltration of the liver with NK-like T-cell lymphoma/leukemia can cause acute liver failure.

    We report a case of primary small-cell lymphocytic lacrimal gland lymphoma in a male diagnosed with primary antiphospholipid syndrome. These rare lymphomas are usually presented in the clinic as disseminations secondary to chronic lymphocytic leukaemia, and the primary site is rare in the orbit. Non-Hodgkin lymphomas are a heterogeneous group of tumours. Although treatment in the IE stage is usually radiotherapy, due to its association with antiphospholipid syndrome, systemic treatment with rituximab was administered.

    Objective: To study the CT findings of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. Methods: The CT examinations of 12 patients with pathologically proven pulmonary MALT lymphoma were reviewed retrospectively. Evaluated imaging findings included number, distribution, shape, attenuation and other associated findings of each lesion were evaluated. Results: Thirty-two pulmonary lesions, including consolidations, masses, nodules and lesions with ground glass attenuation, were identified in 12 patients. Multiple lesions were founded in 10 of 12 patients and solitary lesion in 2 patients. Multiple lesions found in one lung in 2 patients, and multiple lesions found in both lungs in 8 patients. Ten cases demonstrated 21 consolidation lesions with air bronchogram, and one of the ten cases demonstrated two lesions with airway dilatation. Three cases demonstrated 5 masses or nodular lesions, 3 of these 5 lesions showed air bronchogram. Two cases demonstrated 6 ground glass attenuation lesions. One case showed mediastinal and hilar lymphadenopathy. Conclusion: Pulmonary MALT lymphoma usually appears as multiple bilateral consolidations, masses, nodules with air bronchogram or lesions with ground- glass attenuation at CT imaging. The imaging findings described above and with an indolent clinical course may suggest the diagnosis of pulmonary MALT lymphoma. (authors)

    Full Text Available The case of a previously healthy man who developed primary non-Hodgkin’s lymphoma of the liver is presented. Biopsy confirmed that the tumour was of the diffuse large cell type and was of apparent T-cell origin. The diagnosis of these rare tumours is suggested by the presence of a hepatic mass without lymphadenopathy, splenomegaly or bone marrow involvement, as well as normal carcinoembryonic antigen and alpha-fetoprotein levels. However, histological examination of tissue is essential to confirm the diagnosis. The response to treatment varies, but surgical resection and/or chemotherapy can result in prolonged remissions. The literature on this topic is briefly reviewed.

    Primary pediatric bone lymphoma is a rare form of non-Hodgkin lymphoma. Unlike nodal forms of lymphoma, imaging abnormalities in lymphoma of bone do not resolve rapidly in conjunction with treatment and radiologic findings can remain abnormal for years, making it difficult to evaluate treatment response. To evaluate the utility of imaging in assessment of patients with primary pediatric bone lymphoma. At our institution between 2004 and 2013, six cases of pathology-proven primary pediatric bone lymphoma were diagnosed. Retrospective chart review was performed to assess imaging utilization. Our data were qualitatively compared with existing literature to construct an algorithm for imaging patients with primary lymphoma of bone. Imaging evaluation of patients with primary pediatric bone lymphoma was highly variable at our institution. Conventional imaging was routinely used to evaluate response to treatment, despite lack of appreciable osseous change. Imaging in the absence of symptoms did not alter clinical management. Only positron emission tomography CT (PET/CT) proved capable of demonstrating imaging changes from the pretreatment to the post-treatment scans that were consistent with the clinical response to treatment. Surveillance imaging is likely unnecessary in patients with a known diagnosis of pediatric lymphoma of bone. Pretreatment and post-treatment PET/CT is likely sufficient to assess response. There is little data to support the use of interim and surveillance PET/CT. (orig.)

    We present a 71-year-old female with human herpes virus 8 (HHV8)-unrelated primary effusion lymphoma (PEL)-like lymphoma. Dyspnea and pericardial effusion led to pericardiocentesis, diagnosing diffuse large B-cell lymphoma. She underwent positron emission tomography/computed tomography (PET/CT), which demonstrated hypermetabolic pericardial, pleural, and ascites fluid without lymphadenopathy elsewhere. Malignant fluid in the absence of lymphadenopathy is a hallmark of PEL. PEL is associated with immunodeficiency states such as acquired immunodeficiency syndrome (AIDS) and infectious agents such as HHV8. Our patient had no such history and had not received immunosuppressive chemotherapy. We present the PET/CT findings of this rare case of HHV8-unrelated PEL-like lymphoma

    With approximately 10000 cases per year in France, non-Hodgkin's lymphoma (NHL) represents the most frequent hematological malignancy, and 5 to 10 % of new cases of cancers. NHLs constitute a heterogeneous group of lympho-proliferative diseases, including entities with very different epidemiological and evolutive characteristics, as well as prognosis and treatments. Several classifications exist, but in practice, we individualize aggressive NHL including Diffuse Large B-Cell Lymphomas (DLBCL) which is the most common lymphoma, and indolent NHL including follicular lymphomas and mucosa-associated lymphoid tissue (MALT) lymphomas. The role of the radiotherapy in the management of NHLs varies according to the specific sub-type of lymphoma, but it has become increasingly limited over time. Overall it finds indications with curative intent only in situations of localized LMNH: either associated with chemotherapy as part of a combined modality therapy as for the treatment of localized DLBCL, or as exclusive treatment specially in the rare situations of localized follicular lymphomas. Moreover, lymphocytes being extremely radiosensitive cells, radiotherapy retains excellent indications with palliative intent for the management of symptomatic bulky tumor masses, and that whatever the sub-type of NHLs may be. It is important to remember that even today the 'Involved Field' irradiation type remains the gold standard for the treatment of nodal NHLs, even if we witness at present the emergence of new types of irradiation, which aim to reduce the amount of irradiated tissues to try to limit the risks of delayed radio-induced complications. The purpose of this article is to clarify the specific aspects (epidemiological, radio-anatomical and prognostic characteristics) of each NHLs'sub-types (except primary central nervous system lymphomas), as well as the practical modalities of the irradiation (illustrated by a clinical case record) when an indication of

    Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of diffuse large B-cell lymphoma. There have been only a limited number of reports regarding pituitary dysfunction associated with IVLBCL. We present a 71-year-old woman with hypopituitarism without any hypothalamic/pituitary abnormalities as assessed by magnetic resonance imaging. She presented with edema, abducens palsy, and elevated levels of lactate dehydrogenase and soluble interleukin-2 receptor. Provocative testing showed that the peaks of luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone and adrenocorticotropic hormone were evoked to normal levels by simultaneous administration of luteinizing hormone-releasing hormone, thyrotropin-releasing hormone and corticotropin-releasing hormone, but the responses of these four pituitary hormones showed a delayed pattern. She was diagnosed with IVLBCL with cerebrospinal invasion by pathological findings of the bone marrow, skin, and cerebrospinal fluid. She achieved hematological remission after immunochemotherapy. Pituitary function was also restored without hormonal replacement, and the improvement of the pituitary function was confirmed by dynamic testing. We reviewed the literature with respect to hypopituitarism associated with IVLBCL. There were less than 20 case reports and most of the patients died. Endocrinological course was described in only two cases, and both of them required hormonal supplementation. To our knowledge, this is the first case of hypopituitarism induced by IVLBCL that was successfully managed by immunochemotherapy alone. This case suggests that early diagnosis and treatment of IVLBCL might improve anterior pituitary function and enable patients to avoid hormone replacement therapy.

    Previous studies have suggested that diet might affect risk of lymphoma subtypes. We investigated risk of lymphoma and its major subtypes associated with diet in the Mediterranean island of Sardinia, Italy. In 1998-2004, 322 incident lymphoma cases and 446 randomly selected population controls participated in a case-control study on lymphoma etiology in central-southern Sardinia. Questionnaire interviews included frequency of intake of 112 food items. Risk associated with individual dietary items and groups thereof was explored by unconditional and polytomous logistic regression analysis, adjusting by age, gender and education. We observed an upward trend in risk of lymphoma (all subtypes combined) and B-cell lymphoma with frequency of intake of well done grilled/roasted chicken (p for trend=0.01), and pizza (p for trend=0.047), Neither adherence to Mediterranean diet nor a frequent intake of its individual components conveyed protection. We detected heterogeneity in risk associated with several food items and groups thereof by lymphoma subtypes although we could not rule out chance as responsible for the observed direct or inverse associations. Adherence to a Mediterranean diet does not seem to convey protection against the development of lymphoma. The association with specific food items might vary by lymphoma subtype.

  13. Malignant lymphoma incidentally diagnosed due to the perforation of the small intestine caused by a fish bone: A case report

    Directory of Open Access Journals (Sweden)

    Masatsugu Hiraki

    Full Text Available Introduction: The ingestion of a foreign body is relatively common. However, it rarely results in the perforation of gastrointestinal tract. We herein report an unusual case of malignant lymphoma incidentally diagnosed after the perforation of the small intestine by a fish bone. Presentation of case: A 90-year-old woman was admitted to our hospital because of abdominal pain and vomiting. Abdominal computed tomography demonstrated free air and ascites in the abdominal cavity. In the pelvic cavity, a radiopaque linear shadow about 35 mm in diameter was shown in the small intestine, and the stricture was exposed to the abdominal cavity. Therefore, a diagnosis of perforation of the small intestine due to ingestion of a foreign body and panperitonitis was made. Emergent laparotomy was performed. The intraoperative findings revealed perforation of the small intestine with a fish bone in the jejunum. Local inflammation at the perforation site was seen, and circulated wall thickness was observed at the distal side of the jejunum. Partial resection of the jejunum and anastomosis of jejuno-jejunostomy was performed. A pathological examination and immunohistochemical study of the resected specimen resulted in a diagnosis of malignant lymphoma of follicular lymphoma Grade 1. Discussion: It is very difficult to identify the existence malignancy accompanied with gastrointestinal perforation with ingestion of a foreign body. Conclusion: In cases suspected of involving malignancy, careful observation during surgery is needed in order to avoid missing the accompanying malignancy.

    2013-09-01

    The purpose of this study is to describe the sonographic appearance of lymphoma of the gastrointestinal tract in dogs. A retrospective review was conducted and patients with gastrointestinal lymphoma diagnosed by histopathology (including immunohistochemistry, where available) or cytology that had an abdominal ultrasound were included. Four of 15 (26·7%) cases with histopathologically confirmed lymphoma exhibited no sonographic abnormalities. In the dogs with sonographic abnormalities, features including intestinal wall thickness and the presence or absence of wall layering were highly variable. Clinical signs pertaining to the gastrointestinal tract were also unreliable markers of gastrointestinal lymphoma, with weight loss, vomiting, and diarrhoea being uncommon presenting complaints; intestinal obstruction was not present in any patient. The sonographic appearance of gastrointestinal lymphoma in dogs is non-specific. Gastrointestinal lymphoma in dogs should be maintained as a differential diagnosis despite a sonographically normal appearing bowel. © 2013 British Small Animal Veterinary Association.

    Primary non-Hodgkin’s lymphoma’s of the tongue is very rare and accounts for 1% of all malignant tumor of the oral cavity. Clinical features are non-specific ulcerative lesions that do not heal. In the literature, the majority of cases are diffuse large B cell type however, T cell phenotype also may occur. We describe a 77 years old man, who presented with an ulcerative mass in the left margin of the tongue the diagnosis diffuse large B cell lymphoma was confirmed. The patient is actually on treatment R-mini CEOP and has favorable evolution. PMID:28292136

    Nine cases of primary intracranial malignant lymphoma, which accounts for 3.3 % of all intracranial tumors seen in the authors' institution, were studied in terms of diagnostic computed tomographic (CT) features, the tumors' histologic appearance, treatment, post-treatment blood immunologic and cerebrospinal fluid (CSF) characteristics, and outcome. The patients were seven males and two females aged 42 to 67 years. Their chief signs and symptoms on admission were intracranial hypertension, focal signs, and disturbance of consciousness. CT, which proved the most useful preoperative diagnostic technique, demonstrated multiple lesions in seven cases and, in all cases, regions of isodensity or slight high density that were enhanced by contrast medium. According to the patterns of enhancement, the tumors were classed as diffuse (three cases) or nodular (six cases). The former is considered typical of malignant lymphoma, whereas the latter type was sometimes indistinguishable from metastatic tumor and meningioma. At surgery, one patient underwent radical tumor excision, two partial removal, and six biopsy only. Histologic examination revealed one tumor to be of the diffuse small cell type, three of the medium cell type, and five of the large cell type (Lymphoma Study Group classification). Of seven tumors in which lymphocytes were examined by peroxidase-antiperoxidase staining, four were of the B cell type. Postoperatively, whole brain irradiation with 29 to 46 Gy was followed by local irradiation with 15 to 50 Gy. If the tumor persisted, one of three chemotherapies was administered. In one case, methotrexate was given intrathecally. Seven patients were divided into two groups: long remission (three) and recurrence (four). These two groups were compared in terms of serum immunoglobulin levels, T and B cell ratios, CSF characteristics, CT features, tumor cell type, and treatment. No clear differences were found.

    Full Text Available Abstract Background Both thyroid lymphoma and anaplastic carcinoma of thyroid present with rapidly growing mass in eldery patients. Anaplastic carcinoma has high mortality rate and combination of surgery, radiation therapy and multidrug chemotherapy are the best chance for cure. Prognosis of thyroid lymphoma is excellent and chemotherapy for widespred lymphoms and radiotherapy with or without adjuvant chemotherapy for tumors localized to the gland, are the treatment of choice. Case report This article reports a 70 year old man presenting with diffuse neck swelling and hoarseness of few weeks duration. Fine needle aspiration was done and reported as anaplastic carcinoma of thyroid which thyroidectomy was planned. The slides were sent for second opinion. After review, with initial diagnosis of anaplastic carcinoma versus lymphoma, immunocytochemical study was performed. Smears were positive for B cell markers and negative for cytokeratin, so with the impression of diffuse large B cell lymphoma, the patient received two courses of chemotherapy by which the tumor disappeared during two weaks. Conclusion Despite previous reports, stating easy diagnosis of high-grade thyroid lymphoma on the grounds of cytomorphological features we like to emphasize, overlapping cytologic features of the curable high grade thyroid lymphoma form noncurable anaplastic thyroid carcinoma and usefulness of immunocytochemistry to differentiate these two disease.

    Primary central nervous system lymphoma (PCNSL) of T cell origin is rare in pediatric patients. We report a case of T cell PCNSL in a 12-year-old boy and review the literature to highlight the importance of brain biopsy to definitively establish the diagnosis when PCNSL is suspected. A 12-year-old boy presented with worsening left-sided weakness, nausea, vomiting, headache, blurred vision, and diplopia. Magnetic resonance imaging revealed right parietal gyral thickening with faint meningeal contrast enhancement. No clear diagnosis was identified after serum testing, cerebrospinal fluid analysis, and cerebral angiography. To establish the diagnosis definitively, a right craniotomy and open, frameless stereotactic biopsy were performed, which yielded the diagnosis of lymphoblastic T cell lymphoma. PCNSL of T cell origin in children remains poorly studied, with only 18 detailed cases reported over the last three decades, including this case. Establishing a definitive diagnosis of PCNSL is challenging, and a brain biopsy is often required to obtain enough tissue for pathological analysis. Increasing awareness and identification of children diagnosed with T cell PCNSL is needed to better understand the molecular biology of this disease and develop more standardized treatment regimens.

    Multiple lymphomatous polyposis (HLP) is an unusual form of non-Hodgkin's lymphoma characterized by polyps throughout the gastrointestinal tract. It has been reported that most MLP are observed in cases with mantle cell lymphoma of B-cell type. We herein present a case of a 66-year-old man with adult T-cell leukemia/lymphoma (ATLL). Colonoscopy revealed MLP throughout the colon and histopathological findings of ATLL cell infiltration. The patient died despite combination of chemotherapy. The literature of manifestations of colonic involvement of ATLL is reviewed and the importance of endoscopic evaluation to differentiate ATLL intestinal lesions from opportunistic infectious enterocolitis is discussed.

    Jumping translocations (JT) are rare cytogenetic aberrations in hematological malignancies that include unbalanced translocations involving a donor chromosome arm or chromosome segment that has fused to two or more different recipient chromosomes in different cell lines. We report five cases associated with different hematologic disorders and JT to contribute to the investigation of the origin, pathogenesis, and clinical significance of JT. These cases involve JT of 1q in a case of acute myeloblastic leukemia (AML)-M1, a case of Burkitt lymphoma, and a case of BCR/ABL-positive acute lymphoblastic leukemia, as well as a JT of 13q in a case of AML-M5, and a JT of 11q segment in a case of undifferentiated leukemia. To our knowledge, with regard to hematologic malignancies, this study presents the first case of JT associated with AML-M1, the first case of JT involving 13q as a donor chromosome, and the first report of JT involving a segment of 11q containing two copies of the MLL gene, jumping on to two recipient chromosomes in each cell line and resulting in six copies of the MLL gene. Our investigation suggests that JT may not contribute to the pathogenesis but rather to the progression of the disease, and it demonstrates that chromosome band 1q10 as a breakpoint of the donor chromosome 1q is also implicated in AML, not only in multiple myeloma as it has been known until now.

    Introduction: Retrospective analysis of sonographic patterns of renal lymphoma in B-mode imaging and contrast-enhanced ultrasound (CEUS). Patients/methods: From January 2000 to June 2014, 27 patients with clinical or histologically confirmed renal lymphoma were examined with B-mode imaging, followed by CEUS in 8 cases. Results: In B-mode imaging renal lymphoma were hypoechoic in all 27 cases (100%). 9 patients (33.3%) had a bilateral, 18 (66.7%) patients had an unilateral lymphoma infiltration of the kidneys. 8 (29.6%) cases of small nodular, 5 (18.5%) cases of large nodular and 6 (22.2%) cases of perirenal lymphoma infiltration of the kidney were observed in B-mode imaging. Bulky-formation of renal lymphoma was detected in 6 (22.2%) patients and 2 (7.4%) patients had a diffuse lymphoma infiltration of the kidneys. In CEUS an arterial isoechoic enhancement was observed in 5 (62.5%)- and, an arterial hypoechoic enhancement was observed in 3 (37.5%) cases of renal lymphoma. A hypoechoic enhancement in the parenchymal phase was observed in 8 (100%) cases of renal lymphoma infiltration. Conclusion: In B-mode-imaging, nodular lymphoma infiltration of the kidneys is the most common of all renal lymphoma patterns in B-mode imaging. In CEUS, renal lymphoma presented an arterial iso- or hypoechoic enhancement, followed by a hypoechoic enhancement in the parenchymal phase. In regard to the differentiation of renal lymphoma to benign lesions of the kidney, CEUS may be helpful. However, the differentiation of renal lymphoma from other malignant lesions of the kidney like renal cell carcinoma is not feasible by CEUS

    AIM:To assess the significance of chromosome translocation t(11;18)(q21;q21),B-cell lymphoma 10 (BCL-10)protein and Helicobacter pylori (H.pylori) infection in gastric mucosa-associated lymphoid tissue (MALT) lymphoma in Colombia.METHODS:Fifty cases of gastric MALT lymphoma and their respective post-treatment follow-up biopsies were examined to assess the presence of the translocation t(11;18)(q21;q21) as identified by fluorescence in situ hybridization; to detect protein expression patterns of BCL10 using immunohistochemistry; and for evaluation of tumor histology to determine the correlation of these factors and resistance to H.pylori eradication.RESULTS:Infection with H.pylori was confirmed in all cases of gastric MALT lymphoma in association with chronic gastritis.Bacterial eradication led to tumor regression in 66% of cases.The translocation t(11;18)(q21;q21) was not present in any of these cases,nor was there evidence of tumor transformation to diffuse large B-cell lymphoma.Thirty-four percent of the patients showed resistance to tumor regression,and within this group,7 cases,representing 14% of all those analyzed,were considered to be t(11;18)(q21;q21)-positive gastric MALT lymphomas.Protein expression of BCL10 in the nucleus was associated with the presence of translocation and treatment resistance.Cases that were considered unresponsive to therapy were histologically characterized by the presence of homogeneous tumor cells and a lack of plasmacytic differentiation.Responder cases exhibited higher cellular heterogeneity and a greater frequency of plasma cells.CONCLUSION:Both t(11;18)(q21;q21)-positive MALT lymphoma cases and those with nuclear BCL10 expression are considered resistant to H,pylori eradication.It is suggested that chronic antigenic stimulation is not a dominant event in resistant cases.

    2007-09-15

    Substantial heterogeneity has been observed among case-control studies investigating associations between non-Hodgkin's lymphoma and familial characteristics, such as birth order and sibship size. The potential role of selection bias in explaining such heterogeneity is considered within this study. Selection bias according to familial characteristics and socioeconomic status is investigated within a United Kingdom-based case-control study of non-Hodgkin's lymphoma diagnosed during 1998-2001. Reported distributions of birth order and maternal age are each compared with expected reference distributions derived using national birth statistics from the United Kingdom. A method is detailed in which yearly data are used to derive expected distributions, taking account of variability in birth statistics over time. Census data are used to reweight both the case and control study populations such that they are comparable with the general population with regard to socioeconomic status. The authors found little support for an association between non-Hodgkin's lymphoma and birth order or family size and little evidence for an influence of selection bias. However, the findings suggest that between-study heterogeneity could be explained by selection biases that influence the demographic characteristics of participants.

    Pulmonary lymphoproliferative disorders include plasma cell granuloma, Castleman's disease, pseudolymphoma, lymphocytic interstitial pneumonia, angioimmunoblastic lymphadenopathy and lymphomatoid granulomatosis. We carried out a retrospective study for the purpose of analysing the clinical and radiological findings of 16 cases of pulmonary lymphoproliferative disorders seen during the decade 1980-1990. The cases comprised 8 lymphocytic interstitial pneumonia, 5 lymphomatoid granulomatosis, 2 plasma cell granuloma and 1 angioimmunoblastic lymphadenopathy. Owing to the overlap and low specificity of the radiological patterns in these processes, histopathological examination is required. In view of the frequent evolution of pulmonary lymphoproliferative disorders to malignant lymphoma (4 cases, 1 of lymphocytic interstitial pneumonia and 3 of lymphomatoid granulomatosis, in our series) we provide a description of the radiological changes that occur during this process.

    Full Text Available Subcutaneous panniculitis-like T-cell lymphoma (SPTL is a rare tumor from αβ mature cytotoxic T-lymphocytes, which primarily affects the subcutaneous adipose tissue and has morphological manifestations similar to panniculitis. SPTL frequency is less than 1 % of all NHL. It occurs in all age groups, but only 19–20 % are patients younger 20 years. Median age of patients is 35–36 years. To date are only a few cases in children described. In this article we described 3 SPTL cases in patients 1, 10 and 17 years old with typical clinical presentation and detailed analysis.

    A 71-year-old male was admitted to Kohka Public Hospital on January 4, 1980, because of frequent vomiting and recent memory loss. Two weeks before admission upper G-I series showed no abnormalities. Physical and neurological examinations revealed no abnormalities except for slightly apathetic appearance and recent memory loss. Mild pleocytosis and marked increase of protein in CSF were observed. CT scan on January 17 showed high density areas in both medial sides of temporal lobes with remarkable contrast enhancement. His memory and, consciousness disturbances gradually aggravated, accompanied by abnormal density spreading around the ventricle walls like ventriculitis. He was transfered to Kyoto University Hospital on March 17, and malignant lymphoma was diagnosed on the basis of CSF cytology. Radiation and chemotherapy alleviated the CNS involvement and he regained normal mental function. On June 16, he developed pneumonia followed by status epilepticus. Autopsy findings revealed no lymphoid cell infiltration, but fibrous tissues in both hippocampal gyri and lymphomatous cells in the liver, which could not be suspected on clinical examinations. Apparent malignant lymphoma cells were not found in lymph nodes. This case indicated peculiar evolution of malignant lymphoma from liver to CNS or vice versa. We could not decide which organ was primary. CT findings of this case was very interesting; they resembled ventriculitis, which simulate tumors such as medulloblastoma or ependymoma spreading under ependymal lining.

    Objective: To evaluate the clinical application value of nuclide bone imaging in malignant lymphoma. Methods: 71 cases of patients were diagnosed by pathology as malignant lymphoma, among whom there were 8 cases of Hodgkin disease (HL) and 63 cases of non-Hodgkin disease (NHL). The examinations were performed from 2.5 to 6 hours later after the intravenous injection of 99m Tc-MDP (555-925 MBq). Results: 31 cases were bone-infiltrating lesions, including 3 cases of HL and 28 cases of NHL. The total number of the focus was 103, except 2 cases of bone lack, including 35 foci in vertebral column (34.65%), 30 foci in limb and joint (29.70%), 14 foci in rib (13.86%), 13 foci in elvis (12.0%), 5 foci in skull (4.95%) and 4 foci in sternum (3.96%). Conclusion: The nuclide bone imaging has a high value in the clinical stage, therapeutic observation and prognosis of bone-infiltrating malignant lymphoma. (authors)

    2008-12-15

    We report a case of primary multifocal osseous lymphoma in a 6-year-old girl presenting with multifocal osteolytic lesions without systemic symptoms or identifiable non-osseous primary tumor. The differential diagnoses for such a presentation include histiocytosis X, chronic recurrent multifocal osteomyelitis, acute lymphoblastic leukemia, metastatic disease, and primary bone lymphoma. Although non-Hodgkin lymphoma is common in the pediatric population, its presentation as a primary bone tumor, especially with multifocal disease, is extremely rare and is frequently misdiagnosed. We hope that awareness of this entity will help radiologists achieve timely diagnosis and intervention. (orig.)

    IMPORTANCE: To date, the clinical features of the various subtypes of conjunctival lymphoma (CL) have not been previously evaluated in a large cohort. OBJECTIVE: To characterize subtype-specific clinical features of CL and their effect on patient outcome. DESIGN, SETTING, AND PARTICIPANTS...... age was 61.3 years, and 55.1% (145 of 263) were female. All lymphomas were of B-cell type. The most frequent subtype was extranodal marginal zone lymphoma (EMZL) (68.4% [180 of 263]), followed by follicular lymphoma (FL) (16.3% [43 of 263]), mantle cell lymphoma (MCL) (6.8% [18 of 263]), and diffuse...... large B-cell lymphoma (DLBCL) (4.6% [12 of 263). Conjunctival lymphoma commonly manifested in elderly individuals (age range, 60-70 years old), with EMZL having a female predilection (57.8% [104 of 180]) and MCL having a marked male predominance (77.8% [14 of 18]). Unlike EMZL and FL, DLBCL and MCL were...

    Full Text Available Background: Primary cutaneous lymphomas (PCLs represent a heterogeneous group of T- and B-cell lymphomas that present in the skin with no evidence of extracutaneous disease at the time of diagnosis. The aim of this study was to assess and report the epidemiological characteristics of PCLs in Isfahan, Isfahan Province, Iran - as a main province of Iran. Materials and Methods: A total of 99 patients were recruited over a recent 10-year period (2003-2013 with diagnosis of PCLs; the patients were classified according to the The World Health Organization/European Organization for Research and Treatment of Cancer (WHO-EORTC criteria. Mean and standard deviations (SDs were used to describe continuous data, numbers, and percentages for categorical data. Statistical significance was defined as P < 0.05. Results: The patients comprised 45 men and 54 women aged 5-80 years (median 36 at diagnosis. The male-to-female ratio was 1:1.2. Histological examination showed features of primary cutaneous B-cell lymphomas (PCBCLs in four cases. The mean ± SD age in primary cutaneous T-cell lymphomas (PCTCLs and PCBCLs was 37.9 ± 16.5 years and 39.7 ± 9.1 years, respectively (P = 0.72. The mean ± SD latent period between the time of diagnosis and initiation of skin lesions in men and women was 2.3 ± 4.1 years and 5.9 ± 10.1 years, respectively (P = 0.02. The most frequent subtypes were mycosis fungoides (MFs (86.9% followed by Sιzary syndrome (SS (4%. Five patients died from PCL-related deaths. Conclusion: The distinguishing epidemiologic characteristics of PCL in Iran are the absence of a male predominance and a lower age of diagnosis. The study highlights the ethnic or regional variations in the clinicoepidemiological characteristics of PCLs.

    The case is presented of a 43 year-old male patient with chronic follicular conjunctivitis, negative bacterial serology, and refractory to local treatment. The incisional biopsy performed showed to be consistent with reactive lymphoid hyperplasia. A year later, a new incisional biopsy showed follicular lymphoma, with no systemic involvement, and he was treated with local radiotherapy. When a chronic follicular conjunctivitis is refractory to treatment, it is essential to perform an incisional biopsy to establish the histopathological diagnosis that can range from chronic inflammation, reactive lymphoid hyperplasia to lymphoma. Follicular lymphoma is rare among conjunctival lymphomas, and the staging is indispensable for the correct therapeutic approach. Copyright © 2014 Sociedad Española de Oftalmología.

  16. Aberrant phenotypes in peripheral T cell lymphomas.

    Science.gov (United States)

    Hastrup, N; Ralfkiaer, E; Pallesen, G

    1989-01-01

    Seventy six peripheral T cell lymphomas were examined immunohistologically to test their reactivity with a panel of monoclonal antibodies against 11 T cell associated antigens (CD1-8, CD27, UCHL1, and the T cell antigen receptor). Sixty two (82%) lymphomas showed aberrant phenotypes, and four main categories were distinguished as follows: (i) lack of one or several pan-T cell antigens (49, 64% of the cases); (ii) loss of both the CD4 and CD8 antigens (11, 15% of the cases); (iii) coexpression of the CD4 and CD8 antigens (13, 17% of the cases); and (iv) expression of the CD1 antigen (eight, 11% of the cases). No correlation was seen between the occurrence of aberrant phenotypes and the histological subtype. It is concluded that the demonstration of an aberrant phenotype is a valuable supplement to histological assessment in the diagnosis of peripheral T cell lymphomas. It is recommended that the panel of monoclonal antibodies against T cell differentiation antigens should be fairly large, as apparently any antigen may be lost in the process of malignant transformation.

    Engel, I.A.; Straus, D.J.; Lacher, M.; Lane, J.; Smith, J.

    1981-01-01

    A retrospective study of 25 patients with malignant lymphoma who had osteonecrosis of either the femoral or humeral head(s) was undertaken. The common factor present among all patients was the administration of intermittent steroid-containing combination chemotherapy. Seventeen Hodgkin's disease patients received chemotherapy predominantly consisting of an alkylating agent, vincristine, procarbazine, and moderate amounts of prednisone. The non-Hodgkin's lymphoma patients were on various moderate dosage steroid-containing protocols, except three who received prolonged high-dose steroid-containing chemotherapy regimens. Sixteen of the 17 Hodgkin's disease patients and five of the eight non-Hodgkin's lymphoma patients received radiotherapy to the bones that subsequently developed osteonecrosis. Two of the three non-Hodgkin's lymphoma patients who were not irradiated were treated with high-dose steroid-containing chemotherapy regimens. Symptoms developed in patients 12 months to 32 months after completion of chemotherapy and radiotherapy, respectively. Osteonecrosis was a long-term complication of treatment between 1970 and 1979 and occurred in 1.6% of the Hodgkin's disease and 0.12% of the non-Hodgkin's lymphoma patients treated. The authors conclude that the patients at highest risk for this complication are those who receive both radiotherapy to the affected bone(s) and intermittent steroid-containing multiple drug chemotherapy

    2017-06-01

    Lymphomas arising in the adrenal are rare, and to our knowledge, 2 cases of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphomas (DLBCL) in an adrenal pseudocyst have been reported. We report an incidental EBV-positive DLBCL arising in an adrenal pseudocyst in a 58-year-old man with a 7-year history of lymphoplasmacytic lymphoma (LPL). The DLBCL was present in the fibrinous exudate, while the LPL resided in the cyst wall. The patient underwent de-roofing of the same cyst 3 years previously; review of histology revealed foci of LPL in the cyst wall, but not of DLBCL. There have been reports of similar microscopic EBV-positive DLBCLs within enclosed cystic spaces. However, all these cases were incidental extranodal primary DLBCLs. Since residual LPL was present alongside DLBCL, with similar light chain restriction, we propose that this may represent transformation, rather than a de novo primary EBV-driven lymphoma.
