    Lesson It is rare for renal cell carcinoma to involve the peritoneum and cause malignant ascites. Furthermore, it is uncommon for malignant ascites to be a presenting feature of this cancer. An unusual case of renal cell carcinoma presenting with malignant ascites is reported, and its response to sunitinib described.

  3. Clinical presentation of renal cell carcinoma

    International Nuclear Information System (INIS)

    Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%. Conclusion: We observed that large number of the patients with RCC presented with haematuria and most of them were male. Common pathological type was clear cell carcinoma. (author)

    Full Text Available Renal clear cell carcinoma (RCC has different manifestations, including uncommon metastasis and paraneoplastic syndromes. Here we report a rare case of RCC presenting as metastasis to the mandible. A 57-year-old patient with mandibular swelling was referred to the dentist. After necessary evaluations, an incisional biopsy of mandible showed metastatic RCC. The patient was referred to the urologist. The patient underwent right radical nephrectomy. Pathological examination showed clear renal cell carcinoma. Every abnormal bone lesion in the oral cavity should be evaluated carefully and the possibility of a malignant lesion should always be considered.

    Full Text Available Renal cell carcinoma is one of the most common tumours after lung and breast cancer to metastasize to the head and neck. Initial presentation by tongue metastasis is extremely rare. A 67-year-oldmale presented with a 4.8 cm mass on his tongue. The result of the punch biopsy from the tongue was diagnosed as a clear cell variant of squamous cell carcinoma. The biopsy was reevaluated due to the renal mass found during the check-up and the rapid enlargement of the mass. The excision of the tongue mass and the radical nephrectomy material confirmed the diagnosis of a metastatic renal cell carcinoma in the tongue and renal cell carcinoma in the kidney. Since metastasis of renal cell carcinoma to the tongue is uncommon it may cause difficulties in diagnosis and proper management. The metastasis of renal cell carcinoma should always be considered in the differential diagnosis among the clear cell neoplasms.

    Full Text Available Malignancy in pregnancy is rare. Carcinomas in pregnancy are mostly kidney cell mass. Renal cell carcinoma (RCC is the commonest malignancy in pregnancy. Because of softness and increased vascularity, rupture of renal cell carcinoma is not uncommon. Here we are presenting a rare case of renal cell carcinoma in pregnancy with spontaneous rupture resulting in massive hemoperitoneum and serious outcome because of late presentation renal cell carcinoma seldom ruptures. A 26 year old woman G2P1L1 with term pregnancy was referred to hospital 80kms away from periphery with non-progression of labour. There was antenatal record suggesting hypertensive disorder of pregnancy in second trimester. On examination, patient was in hypovolemic shock with profuse distension of abdomen. Diagnosis of abruption grade 3 or rupture uterus was made and immediate laparotomy was done. On opening the abdomen, there was hemoperitoneum but uterus was intact. Emergency LSCS done extracted a stillborn baby. There were no retro placental clots also. There was lot of necrotic tissue in the abdomen and there was a tumour arising from lower pole of left kidney which had invaded the renal vessels and had ruptured. Peripartum hysterectomy and left nephrectomy was done. Women did not respond to treatment and died. The objective of presenting this case is the dilemmas faced by the obstetrician in case of shock in 2nd stage of labour. Simple diagnostic tool like renal ultrasound will help to detect at an early stage which could improve the outcome. All cases of hypertensive disorders of pregnancy should be investigated for secondary causes of hypertension. Abdominal USG must be done for all cases of hypertensive disorders of pregnancy in 2nd trimester. Prompt diagnosis and early treatment is the key in management of such condition in pregnancy.

    Full Text Available Large cell neuroendocrine tumor of the urinary bladder is very rare. It is a type of neuroendocrine carcinoma that is morphologically different from small cell carcinoma.This manuscript describes a 67-year-old man who presented with hematuria. Ultrasonogrophic and computer tomography revealed a 5 cm mass in right posterolateral wall of the bladder that invaded perivesical tissue and he subsequently underwent transurethral resection. Microscopic examination showed a tumor with a sheet-like and trabecular growth pattern comprising necrotic areas which infiltrated the muscularis propria. Tumoral cells had coarse chromatin, prominent nucleoli, moderate amount of cytoplasm and immunohistochemically stained strongly positive with synaptophysin, chromogranin and CD56.There are only few case reports of large cell neuroendocrine tumor of the urinary bladder so the biological behavior and the treatment protocol of these tumors are still obscure. Appropriate management protocols and prognostic estimation could be achived by the increased number of cases being reported. Therefore in a case of a poorly differentiated tumor in bladder, although rare, it is important to consider large cell neuroendocrine carcinoma in differential diagnosis.

  16. Large-cell Neuroendocrine Carcinoma of the Lung: Unusual Presentation

    2014-11-01

    Full Text Available Lung cancer is the leading cause of death among malignant tumors. Pulmonary neuroendocrine tumors encompass a broad spectrum of tumors including the large-cell neuroendocrine carcinoma. The case of a 57-year-old white housewife with a history of smoking, diabetes, hypothyroidism and hypertension who sought medical attention because of headache, vomiting, weight loss, neuropsychiatric symptoms and metastatic inguinal lymphadenopathy is presented. The symptoms resulted from the extrapulmonary metastases found. Imaging studies, histology and immunohistochemistry confirmed the diagnosis of large-cell carcinoma of the lung with neuroendocrine pattern. This type of highly aggressive tumor is usually diagnosed when there are already multiple metastases, which affects the short-term prognosis. The aim of this paper is to inform the medical community of this case due to the scarce reports in the literature.

    Full Text Available Abstract Background Primary squamous cell carcinomas of the colorectum are very uncommon. Until now, to the best of our knowledge, only 114 cases of squamous cell carcinoma in the colorectum exist in the reported literature. Here we report a case of squamous cell carcinoma of the rectum in the ethnic Kashmiri population in northern India. Case Presentation The case of a 60-year-old male patient (Asian with a pure squamous cell carcinoma of the rectum is presented here. The patient underwent a curative surgery with concomitant chemotherapy. Two years after the initial curative resection of the tumor he is still alive. Conclusion The prognosis for squamous cell carcinoma of the colorectum is worse than for that of adenocarcinoma, because of the delayed diagnosis. The etiopathogenicity of squamous cell carcinoma of the colorectum is discussed. Surgical resection of the lesion seems to be the treatment of choice. Chemotherapy also helps in improvement of the prognosis.

    2014-07-01

    Full Text Available Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs, bone, adrenal glands, and regional lymph nodes. The incidence of metastasis from renal cell carcinoma to the head and neck region is very low. The tongue is considered a very rare atypical ear, nose, and throat (ENT location for metastasis of renal cell carcinoma. The present case from Iran reports tongue metastasis of renal cell carcinoma (RCC.   Case Report: The following report is based on an 80-year old male patient with a tongue lesion and ambiguous past medical history that ultimately leads to diagnosis of a metastatic RCC. We also updated a previous literature review that was published 2008. A histopathological differential diagnosis for clear-cell tumors is also discussed.   Conclusion:  Because of the rarity of metastatic tumors of the oral region as well as the presence of other lesions with clear cells, diagnosis of metastatic clear-cell RCC in the oral cavity can be very difficult and challenging.  

  4. The present approach to treatment of renal cell carcinoma

    International Nuclear Information System (INIS)

    Until the turn of the millennium, metastatic renal cell carcinoma (mRCC) was regarded as one of the most refractory cancers; highly resistant to both radiation and systemic therapy, and only small group of patients responded to immune modulation. Involved targeted therapies, which influence specific signal transduction pathways of tumor formation and progression, opened new options of treatment to give patients a new hope. After the first experiences with the new biologic agents we can claim, that these patients have improved a quality of life, provided stabilization of disease and prolong life of patients, but the cure is not available. However, there are so many studies with target therapies in RCC, but the most correct algorithm of treatment does not exist. Targeted therapies rarely achieve remission, prevailing a stabilisation of disease so patients have to undergo chronic treatment. In choice of optimal treatment is necessary to regard for quality of life, so usually the winner is the drug with the lowest toxic potential. (author)

    Full Text Available Introduction. Rectal large cell neuroendocrine carcinoma (LCNEC is a poorly differentiated neoplasm that is very rare and belongs within the poorest prognostic subgroup among primary colorectal neoplasms. Here, we describe a case of LCNEC of the rectum, which highlights the aggressive clinical course and poor prognosis associated with this disease. Case Presentation. We report a case of a 63-year-old male who presented to our hospital with a one-month history of lower abdominal pain, constipation, and weight loss. A computed tomography (CT scan of the chest, abdomen, and pelvis revealed a rectal mass as well as metastatic disease of the liver and lung. Flexible sigmoidoscopy revealed a fungating, ulcerated and partially obstructing rectal mass located 6 cm from the anal verge. This mass was biopsied and pathological examination of the resected specimen revealed features consistent with a large cell neuroendocrine carcinoma. Conclusion. Rectal large cell neuroendocrine carcinomas are rare and have a significantly worse prognosis than adenocarcinomas. At diagnosis, a higher stage and metastatic disease are likely to be found. It is important to differentiate large cell, poorly differentiated neuroendocrine carcinomas from adenocarcinomas of the colon and rectum pathologically because patients may benefit from alternative cytotoxic chemotherapeutic regimens.

    Head and neck tumours presenting as a neck abscess are extremely rare. Two patients with laryngeal squamous cell carcinoma, presenting with a prelaryngeal abscess, are described. Although clinically and on the CT studies these cases were suspect for underlying malignancy, the initial biopsies were negative for cancer. Because of persistent suspicion, repeat biopsies finally confirmed the presence of a squamous cell carcinoma. Pathological examination after total laryngectomy showed cancer localised in one of the true vocal cords, invading the anterior commissure and thyroid cartilage. However, the prelaryngeal soft tissues were free of tumour, showing only inflammatory changes and collections of pus. These cases emphasize the importance of repeat targeted biopsies and follow-up CT-studies in patients with a prelaryngeal abscess of obscure aetiology, in order to exclude or confirm a possible underlying malignancy.

    Introduction: Renal cancer is a relatively common neoplasia with renal clear cell carcinoma being the most frequent histological type. This tumor has a strong tendency to metastasize virtually to all organs. Today, new diagnostic tools allow physicians to distinguish between those patients with “incidental findings” and those with advanced metastatic disease. Presentation of case: A 70-year-old male with multiple indolent subcutaneous masses underwent colonoscopy after a positive fecal scr...

    Renal cell carcinomas (RCCs) are neoplasias with high prevalence and mortality. We previously reported that several peptidases may be involved in the pathophysiology of clear cell renal cell carcinoma (CCRCC). Now, to gain insight into the reasons that lead the various RCC types to behave very differently with regard to aggressiveness and response to anticancer treatments, we analyzed subsets of chromophobe renal cell carcinoma (ChRCC), and renal oncocytoma (RO), a benign tumor; as well as different grades and stages of CCRCCs. Particulate APN, APB, and APA activities were decreased in both ChRCC and RO (tumor vs. nontumor tissues). Interestingly, activities were downregulated in a tumor-type specific way and the intensities of the decreases were stronger in the benign tumor than in the malignant type. Moreover, when two key histopathological parameters for tumor prognosis (high vs. low stage and grade) were analyzed, increases of activity were also observed in several of these cell surface peptidases (APN, APB). Some soluble activities (APB, Asp-AP) were also downregulated in the RCCs. With respect to genetic expression, PSA and APN were in a positive correlation related to their activities in both ChRCC and RO; but not APB, Asp-AP, APA, and PGI. These results may suggest an involvement of several peptidases in the pathophysiology of renal cancer, since they presented different patterns of activity and expression in tumors with different behaviors.

    Tumors commonly harbor multiple genetic alterations, some of which initiate tumorigenesis. Among these, some tumor-specific somatic mutations resulting in mutated protein have the potential to induce antitumor immune responses. To examine the relevance of the latter to immune responses in the tumor and to patient outcomes, we used datasets of whole-exome and RNA sequencing from 97 clear cell renal cell carcinoma (ccRCC) patients to identify neoepitopes predicted to be presented by each patient's autologous HLA molecules. We found that the number of nonsilent or missense mutations did not correlate with patient prognosis. However, combining the number of HLA-restricted neoepitopes with the cell surface expression of HLA or β2-microglobulin(β2M) revealed that an A-neo(hi)/HLA-A(hi) or ABC-neo(hi)/β2M(hi) phenotype correlated with better clinical outcomes. Higher expression of immune-related genes from CD8 T cells and their effector molecules [CD8A, perforin (PRF1) and granzyme A (GZMA)], however, did not correlate with prognosis. This may have been due to the observed correlation of these genes with the expression of other genes that were associated with immunosuppression in the tumor microenvironment (CTLA-4, PD-1, LAG-3, PD-L1, PD-L2, IDO1, and IL10). This suggested that abundant neoepitopes associated with greater antitumor effector immune responses were counterbalanced by a strongly immunosuppressive microenvironment. Therefore, immunosuppressive molecules should be considered high-priority targets for modulating immune responses in patients with ccRCC. Blockade of these molecular pathways could be combined with immunotherapies targeting neoantigens to achieve synergistic antitumor activity. Cancer Immunol Res; 4(5); 463-71. ©2016 AACR.

    Miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner's pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and some sarcomas. Although very infrequent, miliary mottling can be seen in primary lung cancers. Herein, we report the case of a 28-year-old female with chest X-ray showing miliary mottling. Thoracic computed tomography (CT) features were suggestive of tuberculoma with miliary tuberculosis. CT-guided fine needle aspiration cytology confirmed the diagnosis as lower-lobe, left lung non-small cell carcinoma (adenocarcinoma). It is rare for the non-small cell carcinoma of the lung to present as miliary mottling. The rarity of our case lies in the fact that a young, non-smoking female with miliary mottling was diagnosed with non-small cell carcinoma of the lung. PMID:23645961

    Cytokeratin-positive interstitial reticulum cell (CIRC) sarcoma is a rare type of dendritic cell tumor derived from a subset of fibroblastic reticular cells. Expression of cytokeratins and extranodal location of these tumors can lead to a misdiagnosis of carcinoma. We report two cases of CIRC sarcomas primarily involving the scalp and breast. Patients were referred with an initial diagnosis of carcinoma. Case 1 underwent wide local excision of the scalp tumor with left posterolateral neck dissection. Case 2 had modified radical mastectomy for the tumor in left breast. Histopathological examination of both specimens showed an epithelioid to spindle cell malignant tumor that co-expressed CK 8, CK 18, vimentin, and smooth muscle actin. A diagnosis of CIRC sarcoma was made. Pathologists should be aware of this subset of dendritic cell sarcoma. Carcinomas, other sarcomas of the accessory dendritic cell family, and poorly differentiated malignant tumors have to be ruled out by combination of morphology, immunohistochemistry, and electron microscopic studies.

    Full Text Available Background & objectives: Clinical spectrum of most of the diseases in developing countries is different from the west. Similarly whether renal cell carcinomas (RCC in a developing country like India is seen in the same spectrum in relation to the age at presentation as in the west is not described in the literature. This study was carried out to investigate the spectrum of RCC in India with regards to age of onset, stage at presentation and survival. Methods: Patients with renal tumour, treated between January 2000 to December 2012 in a tertiary care hospital in north India, were analyzed for age at presentation, clinical features and histopathological characteristics. Clinical diagnosis was made by contrast enhanced computerized tomography (CECT scans and/or magnetic resonance imaging (MRI. Renal masses diagnosed as angiomyolipoma, infective masses and hydatid cysts were excluded from the analysis. Impact of various age groups on gender, tumour size, TNM stage, Fuhrman grade, histopathological subtypes, lymph node, inferior vena cava (IVC involvement and survival was analyzed. Patients were grouped in five age groups i.e. ≤39, 40-49, 50-59, 60-69 and more than 70 yr of age. Results: Of the total 617 patients with 617 renal tumours (2 patients had bilateral tumours but only the larger tumour was considered clinically suspected as RCC, 586 had epithelial cell tumour and the remaining 31 had non epithelial cell tumour. The mean tumour size was 8.08±3.5 cm (median 7, range 1-25 cm. Tumour of less than 4 cm size was present in only 10.4 per cent patients. The mean age at diagnosis was 55.15±13.34 (median 56, range 14-91 yr years. A total of 30.03 per cent of renal tumours presented in patients younger than 50 yr of age. Though there was no difference in stage, Fuhrman′s grade, IVC involvement and lymph nodal spread among various age groups, younger patients had higher proportion of non clear cell RCC and only 48.59 per cent of them presented

    Head neck squamous cell carcinoma (HNSCC) is a common kind of malignancies in human body. For HNSCC in early stage, either surgical operation or radiotherapy can acquire satisfactory treatment results. However, any single treatment modality such as surgery alone or single radiation is insufficient to gain satisfactory tumor control. Multidisciplinary treatment (MDT) has become a mainstay and important therapeutic strategy in the management of HNSCC. Among various approaches in the MDT, concurrent chemoradiotheraqpy (CCR) constitutes a major progress, which implicates a lot in improving outcomes and organ preservations in managing HNSCC. In the present review, the history, mechanisms, indications along with side effects and drawbacks, and perspectives of CCR are to be described and discussed, in the hope of providing effective guidance for the domestic MDT, especially CCR in the management of HNSCC.

    Merkel cell carcinoma (MCC) is a rare malignant cutaneous neuroendocrine tumour with an aggressive behaviour and frequent regional lymph node and distant metastases. It mostly occurs in old patients and the commonest sites are the skin of the head, neck and the extremities. Typically, the primary tumour presents as a fast-growing, painless, reddish nodule with an iceberg-like effect, broadening in the depth. Although the pathogenesis of MCC remains largely unknown, ultraviolet radiation and immunosuppression are likely to play a significant pathogenetic role. The authors describe an unusual case of MCC clinically presenting as lymphedema on the right leg due to an inguinal lymphonodal metastasis. Although extensive investigations were performed the authors were unable to discover the cutaneous primary tumor. The authors examine the etiopathogenesis and hypothesis of this rare tumour and describe the clinical differential diagnosis. They suggest that clinical features together with imaging studies and morphological and immuno-histochemical findings are important for the correct diagnosis. PMID:18497730

    Purpose: Penile squamous cell carcinoma (SCC) is a rare entity, with few published series on outcomes. We evaluated the stage distributions and outcomes for surgery and radiation therapy in a U.S. population database. Methods and Materials: Subjects with SCC of the penis were identified using the National Cancer Institute Surveillance, Epidemiology and End Results (SEER) Program database between 1988 and 2006. Descriptive statistics were performed, and cause-specific survival (CSS) was estimated using Kaplan-Meier analysis. Comparisons of treatment modalities were analyzed using multivariate Cox regression. Subjects were staged using American Joint Committee on Cancer, sixth edition, criteria. Results: There were 2458 subjects identified. The median age was 66.8 years (range, 17-102 years). Grade 2 disease was present in 94.5% of cases. T1, T2, T3, T4, and Tx disease was present in 64.8%, 17.1%, 9.5%, 2.1%, and 6.5% of cases, respectively. N0, N1, N2, N3, and Nx disease was noted in 61.6%, 6.9%, 4.0%, 3.7%, and 23.8% of cases, respectively. M1 disease was noted in 2.5% of subjects. Individuals of white ethnicity accounted for 85.1% of cases. Lymphadenectomy was performed in 16.7% of cases. The CSS for all patients at 5 and 10 years was 80.8% and 78.6%. By multivariable analysis grades 2 and 3 disease, T3 stage, and positive lymph nodes were adverse prognostic factors for CSS. Conclusion: SCC of the penis often presents as early-stage T1, N0, M0, grade 1, or grade 2 disease. The majority of patients identified were treated with surgery, and only a small fraction of patients received radiation therapy alone or as adjuvant therapy.

    Differential diagnosis of neck tumours puts precedence on diagnosing neoplastic lesions. In the case of neck tumours, these are unfortunately late signs, but in patients with a primary neoplastic focus within the head and neck, neck tumour is often the first sign of the disease. The authors describe a clinical case of neck tumour with initially unclear etiology. The preoperative diagnostics including ultrasonography, thin-needle puncture, MRI, carotid angiography and videostroboscopy was significant for surgical treatment planning; yet it was the intraoperative clinical picture which indicated that the tumour derived from the inferior parotid pole. The preoperative histopathological diagnosis using thin-needle biopsy: cellulae carcinomatosae and the clinical picture resulted in block operation with neck lymphatic system removal and tissue defect reconstruction by means of a pectoral flap. The histopathological examination confirmed non-cornifying basal cell epithelioma only in the essential lesion with no metastases to lymph nodes and surrounding tissue margins free of infiltrates. Two and a half years after the procedure, the patient presented with a tumour localized on the front thoracic wall and two rapidly enlarging tumours in the nape of the neck. In the collected specimen of the tumour on the front thoracic wall, a diagnosis of acinic cell carcinoma was made. The deteriorating general condition of the patient, his cancer emaciation, problems with movement and suspected liver metastases confirmed by abdominal USG as well as radiological bone lesions resulted in the abandonment of surgical treatment due to disseminated neoplastic process and the patient was referred for palliative care.

  9. Survival advantage of partial over radical nephrectomy in patients presenting with localized renal cell carcinoma

    International Nuclear Information System (INIS)

    Partial nephrectomy (PN) preserves renal function and has become the standard approach for T1a renal cell carcinoma (RCC). However, there is still an ongoing debate as to which patients will actually derive greater benefit from partial than from radical nephrectomy (RN). The aim of this study was to retrospectively evaluate the impact of the type of surgery on overall survival (OS) in patients with localized RCC. Renal surgery was performed in 4326 patients with localized RCC (pT ≤ 3a N/M0) at six German tertiary care centers from 1980 to 2010: RN in 2955 cases (68.3%), elective (ePN) in 1108 (25.6%), and imperative partial nephrectomy (iPN) in 263 (6.1%) cases. The median follow-up for all patients was 63 months. Kaplan-Meier and Cox regression analyses were carried out to identify prognosticators for OS. PN was performed significantly more often than RN in patients presenting with lower tumor stages, higher RCC differentiation, and non-clear cell histology. Accordingly, the calculated 5 (10)-year OS rates were 90.0 (74.6)% for ePN, 83.9 (57.5)% for iPN, and 81.2 (64.7)% for RN (p < 0.001). However, multivariate analysis including age, sex, tumor diameter and differentiation, histological subtype, and the year of surgery showed that ePN compared to RN still qualified as an independent factor for improved OS (HR 0.79, 95% CI 0.66-0.94, p = 0.008). Even allowing for the weaknesses of this retrospective analysis, our multicenter study indicates that in patients with localized RCC, PN appears to be associated with better OS than RN irrespective of age or tumor size

  10. Human sunlight-induced basal-cell-carcinoma-associated dendritic cells are deficient in T cell co-stimulatory molecules and are impaired as antigen-presenting cells.

    Immune surveillance of skin cancer involves the stimulation of effector T cells by tumor-derived antigens and antigen-presenting cells (APCs). An effective APC must not only display processed antigen in the context of MHC molecules but also express co-stimulatory molecules that are required to fully activate T cells. One of the most common cutaneous neoplasms is basal cell carcinoma. To investigate expression of the co-stimulatory molecules CD80 (B7-1) and CD86 (B7-2) on tumor-associated dendritic cells (TADCs), cryosections from basal cell carcinomas were immunostained. In basal cell carcinomas, only 1 to 2% of intratumor and 5 to 10% of peritumor APCs expressed CD80 or CD86. In contrast, biopsies of immunological/inflammatory dermatoses revealed that 38 to 73% of APCs expressed CD80 and CD86. To further evaluate their phenotype and function, TADCs were isolated from tissue samples of basal cell carcinomas; they were non-adherent to plastic, displayed a typical dendritic morphology, and expressed high levels of major histocompatibility class II molecules on their surface. When TADCs were compared with dendritic cells from blood for presentation of superantigens (staphylococcal enterotoxins A and B) to resting autologous T cells, TADCs were consistently weaker stimulators of T cell proliferation than blood dendritic cells. When analyzed by flow cytometry, TADCs expressed high levels of HLA-DR, but only 5 to 10% co-expressed CD80 or CD86. A 3-day culture in granulocyte/macrophage colony-stimulating factor-containing medium partially reconstituted the TADC expression of CD80 and CD86 as well as their immunostimulatory capacity. Thus, in this common skin cancer, although there are prominent collections of HLA-DR-positive APCs in and around tumor cells, the TADCs are deficient in important co-stimulatory molecules as well as being weak stimulators of T cell proliferation. The paucity of co-stimulatory molecule expression and functional activity of TADCs may explain why

    Renal cell carcinoma (RCC) accounts for approximately 3%of all cancer cases. RCCs usually metastasize to the lungs, bones, liver, or brain. Only<1%of patients with bone metastases manifested clavicular RCC metastases. hTus, clavicular metastasis as the initial presentation of RCC is extremely rare. We report a patient with RCC metastasis to the letf clavicle, which was ifrst presented with pain caused by a pathological fracture. Magnetic resonance image revealed a renal tumor, and technetium-99m–methylene diphosphonate bone scintigraphy showed multiple osseous metastases. The patient eventually underwent surgery to remove the lateral end of the letf clavicle and right kidney. Histopathology revealed renal tumor and clear cell carcinoma in the clavicle. Finally, we review 17 cases of clavicular metastases originating from different malignancies.

    Full Text Available High-grade neuroendocrine carcinoma of the urinary bladder comprehends small-cell and large-cell variants. It is a rare and aggressive neoplasm, mostly diagnosed in advanced stages. It is more frequently encountered among Caucasian men in the sixth decade of life. Urinary symptoms are the most common clinical presentation. Diagnosis is generally not troublesome once the lesions are easily detectable by imaging exams and cystoscopy. This neoplasia is associated with tobacco smoking, and is frequently associated with other carcinomatous components such as urothelial carcinoma, adenocarcinoma, and sarcomatoid carcinoma. The authors report a case of an apparently healthy female patient who presented cervical lymph node enlargement not accompanied by systemic symptoms. The supraclavicular lymph node biopsy revealed metastatic small cell carcinoma. The computed tomography scan showed a bladder wall nodular thickening, enlarged lymph nodes along the iliac, periaortic, mediastinal, cervical and supraclavicular chains, as well as an insufflating lytic bone lesion in the right iliac wing. The positron emission tomography-fluorodeoxyglucose (PET-FDG added to these findings, the presence of a paraesophageal lymph node, lymphadenomegaly in the gluteal region and a vertebral lytic lesion in T10. Resected specimen of the bladder tumor revealed a high-grade neuroendocrine carcinoma with small-cell and large-cell features.

    Renal cell carcinoma (RCC) is often concomitant with distant metastasis, and these metastases are the first sign of an otherwise occult primary. Whereas metastasis of RCC to the head and neck has been reported, metastasis to the masseter muscle, which is composed of skeletal muscle, is quite rare. We now report the case of a 66-year-old man who had a past history of pulmonary tuberculosis, with RCC metastasis of a well-defined intensely enhancing hypervascular mass in the masseter muscle as the initial presentation. We present the imaging findings of this case and a literature review about radiologic differential diagnosis of intramasseteric masses.

    Lung cancer-associated paraneoplastic syndromes affecting the central nervous system present significant diagnostic and treatment challenges. In this case, the patient presented with personality change, cognitive impairment, complex partial seizures, ataxia, dyspraxia, and dysphasia. Shortly after admission, the patient suffered refractory generalized tonic-clonic seizures and a decreased level of consciousness and required intubation, ventilation, and admission to the ICU. He was subsequently diagnosed with paraneoplastic limbic encephalitis based on recognized criteria, including a compatible clinical picture, elevated protein content in his cerebrospinal fluid with negative cytology, a positive positron emission tomography-computed tomography scan showing a right upper lobe tumor, and the exclusion of other neuro-oncological complications. Histopathology confirmed the tissue diagnosis as squamous cell cancer. Initial immunotherapy with steroids and intravenous immunoglobulin and subsequent lobectomy and adjuvant chemotherapy were partially successful, leading to partial resolution of his cognitive impairment. This report highlights the diagnostic and therapeutic challenges of lung-related paraneoplastic syndromes. In addition, it illustrates the poor outcomes for patients and identifies squamous cell cancer as an extremely rare cause of paraneoplastic limbic encephalitis. PMID:25784771

    Horner syndrome, a combination of pupillary miosis, ptosis and facial anhidrosis, results from damage to the oculosympathetic nerve pathways. It can occur anywhere from the hypothalamus to the eye, but to our knowledge, metastatic disease to a node in the neck from a mucosal squamous cell carcinoma (SCC) of the head and neck has not previously been reported as a primary cause in humans. It is surprising that it does not present more often given the frequency of metastatic disease in the neck. We discuss how it may have occurred, and highlight the importance of a thorough examination and investigation of the head and neck in patients who present with unusual neurological signs.

Case report We are reporting a 53-year-old patient who was admitted because of acute pancreatitis. She had no history of gallstones, alcohol abuse, medications or any other predisposition for acute pancreatitis. Further investigations of blood, CT of chest abdomen and neck and ultrasound scan of abdomen, bone marrow and neck lymph node biopsies confirmed advanced small cell carcinoma of the lung with hypercalcemia, which was the only definite cause of acute pancreatitis. The patient made good recovery from pancreatitis after controlling the hypercalcemia. She was referred to respiratory team for further management of lung cancer. Conclusion Acute pancreatitis due to hypercalcemia of advanced small cell carcinoma of the lung is an extremely rare condition. Acute pancreatitis due to hypercalcemia should be thoroughly investigated to exclude serious pathology as in our case.

    Metastatic renal carcinoma is the third most common source of ocular and second most common source of orbital metastases. This is the first published case of von Hippel-Lindau (vHL) disease that developed renal cell carcinoma metastatic to an eye with a retinal hemangioblastoma. A 73-year-old woman had a history of vHL disease that included prior retinal hemangioblastomas, 2 cerebellar hemangioblastomas, and bilateral renal cell carcinomas with sacral metastasis. After presenting with progressive, painful proptosis secondary to a large mass observable by ocular CT, an enucleation-orbitotomy was performed, and the surgical specimen was sent for histopathological analysis. The ophthalmic renal metastatic tumor, like the primary tumor, was a clear cell variant that involved both the eyeball and orbit in continuity. The intraocular component was larger than the extraocular portion, which was interpreted as an outward extension of an initial retinal metastasis that probably first settled within a hemangioblastoma. Clusters of ectatic ghost vessels with thickened walls produced by periodic acid Schiff-positive, redundant basement membrane material were partially infiltrated by tumor cells at their periphery, thereby lending some support for this hypothesis. Immunohistochemical positivity for the biomarkers cytokeratin 18, vimentin, carbonic anhydrase IX, PAX2, and PAX 8 confirmed the diagnosis. The patient has refused further treatment. Her anophthalmic socket has comfortably retained a porous polyethylene implant without clinical evidence of local recurrence during 5 months of follow up. PMID:24828963

    Small cell carcinoma (SCC) of the prostate is an uncommon condition; there are very few cases in which presenting symptoms are consistent with Cushing Syndrome (CS). We report a new case in which CS triggers the suspicion of an SCC of the prostate and a review of the published cases of SCC of the prostate presenting with CS. The origin of these neoplasms is still unclear. It may be suspected when laboratory features appear in patients diagnosed with prostatic adenocarcinoma which becomes resistant to specific therapy. SCC usually occurs after the 6th decade. Patients suffering SCC of the prostate presenting with CS usually present symptoms such as hypertension, hyperglycemia, alkalosis or hypokalemia; cushingoid phenotype is less frequent. Cortisol and ACTH levels are often high. Prostatic-specific antigen levels are usually normal. CT scan is the preferred imaging test to localize the lesion, but its performance may be improved by adding other tests, such as FDG-PET scan. All patients have metastatic disease at the time of diagnosis. Lymph nodes, liver and bone are the most frequent metastases sites. Surgery and Ketokonazole are the preferred treatments for CS. The prognosis is very poor: 2- and 5-year survival rates are 27.5 and 14.3%, respectively. Key messages When a patient presents with ectopic Cushing Syndrome but lungs are normal, an atypical localization should be suspected. We should suspect a prostatic origin if Cushing Syndrome is accompanied by obstructive inferior urinary tract symptoms or in the setting of a prostatic adenocarcinoma with rapid clinical and radiological progression with relatively low PSA levels. Although no imaging test is preferred to localize these tumors, FDG-PET-TC can be very useful. Hormone marker scintigraphy (e.g. somatostatin) could be used too. As Cushing Syndrome is a paraneoplastic phenomenon, treatment of the underlying disease may help control hypercortisolism manifestations. These tumors are usually metastatic by the

    From January 1988 to December 1993, we identified six men with minimally invasive (stage I) squamous cell carcinoma of the anus and 10 men with anal carcinoma in situ (CIS). Of the six patients with invasive carcinoma, four were infected with human immunodeficiency virus (HIV), including one with AIDS. Of the 10 patients with CIS, eight were infected with HIV, including four with AIDS. Anal pain and bleeding were the most common symptoms of minimally invasive anal cancer and anal CIS. Anal irritation, burning, or pruritus occurred more frequently in patients with CIS, whereas anal ulcers, masses, or abscesses were more frequent in patients with minimally invasive cancer. Several patients with CIS had a discrete area of leukoplakia in the anal canal or a pigmented plaque of the anus and anal canal. These lesions were not observed in patients with minimally invasive anal cancer. The symptoms and signs of early-stage anal cancer in men at risk for developing HIV infection or men infected with HIV often resemble those of other common anorectal diseases in homosexual men. Anal cancer in HIV-infected men is not limited to those individuals with AIDS. PMID:8527551

    Ninety percent of patients with head and neck squamous cell carcinomas (HNSCC) have overexpression of epidermal growth factor receptor (EGFR), which is correlated with poor prognosis. Complete surgical resection of HNSCC tumors has a large impact on patient survival, where detection of tumor at or close to surgical margins increases the risk of death at 5-years by 90%. In addition, large surgical margins can greatly increase the morbidity experienced by the patient due to functional and cosmetic damage of oral and facial structures. Single fluorescence targeting agents are often used for tumor detection in in vivo pre-clinical imaging; however, the arising signal is qualitative at best because it is a complex mixture of vascular perfusion, vascular leakage, inhibited lymphatic clearance, and receptor binding. In vivo ratiometric receptor concentration imaging (RCI) allows quantification of receptor expression (hence identification of cancerous tissue) by utilizing co-administered paired-agents consisting of a targeted agent and non-targeted perfusion agent to reference the plasma delivery and leakage. A panel of HNSCC tumors with varying levels of EGFR expression (SCC-15 >SCC-25 > SCC-09) have been imaged using ABY-029, a clinically relevant anti-EGFR affibody labeled with IRDye 800CW, and affibody control imaging agent labeled with IRDye 680RD. RCI maps of in vivo tissue have been created and are spatially correlated with EGFR and CD31 immunohistochemistry and basic H and E staining. The RCI threshold parameters for distinguishing tumor from normal tissues (skin and muscle) and the accuracy of margin detection in these tumors will be presented. RCI surgical resection will be further developed using a novel multi-channel, gated fluorescence-guided surgery (FGS) imaging system that is capable of performing RCI in normal room light.

    Full Text Available Metastatic lesions of renal cell carcinoma (RCC occasionally regress spontaneously after surgical removal of the primary tumor. Although this is an exceptionally rare occurrence, RCC has thus been postulated to be immunogenic. Immunotherapies, including cytokine therapy, peptide-based vaccines, and immune checkpoint inhibitors have therefore been used to treat patients with advanced, metastatic RCC. We review the history, trends, and recent progress in immunotherapy for advanced RCC and discuss future perspectives, with consideration of our experimental work on galectin 9 and PINCH as promising specific immunotherapy targets.

  19. Occult breast carcinoma presenting as axillary metastases

    International Nuclear Information System (INIS)

    Purpose: Breast carcinoma presenting with axillary lymphadenopathy and no clinical or radiological evidence of a primary tumor is a rare presentation. We aimed to examine the management of the breast by observation, radiation therapy, or mastectomy. Methods and Materials: Departmental records from 1979 to 1996 of unknown primary presentations and cases of T0N1-2M0 breast carcinoma were reviewed to find cases of occult breast carcinoma presenting as axillary lymphadenopathy with no clinical or imaging evidence of a primary tumor. Results: There were 6047 presentations of breast carcinoma with 20 cases of occult breast carcinoma meeting the criteria. The breast was treated by observation in 6 cases, mastectomy in 2 cases, and radiotherapy to the intact breast in 12 cases. Eighty-three percent of patients (5 of 6 patients) who had observation of the breast had a local recurrence, compared to 25% who had radiotherapy to the intact breast (3 of 12 patients) and 0% who had a mastectomy (0 of 2 patients). The median recurrence-free survival was 7 months in patients who had observation of the breast, compared to 182 months in patients who had local treatment. Three of the 6 patients who underwent breast observation have died whereas 1 of the 14 who had local treatment have died, with a mean follow-up of 73 months. It was found that patients having observation of the breast had a poorer recurrence-free survival (p = 0.003) and overall survival (p = 0.05) compared to those having local treatment of the breast. Conclusions: Patients with such a presentation should have a complete physical examination, mammography, ultrasound, and MRI of the breasts. If there remains no evidence of a primary tumor, an axillary dissection should be carried out and the breast treated by radiotherapy or mastectomy. Observation of the breast is not a recommended option

    During fluorescence-guided surgery, a cancer-specific optical probe is injected and visualized using a compatible device intraoperatively to provide visual contrast between diseased and normal tissues to maximize resection of cancer and minimize the resection of precious adjacent normal tissues. Six patients with squamous cell carcinomas of the head and neck region (oral cavity (n=4) or cutaneous (n=2)) were injected with an EGFR-targeting antibody (Cetuximab) conjugated to a near-infrared (NIR) fluorescent dye (IRDye800) 3, 4, or 7 days prior to surgical resection of the cancer. Each patient's tumor was then imaged using a commercially available, open-field NIR fluorescence imaging device each day prior to surgery, intraoperatively, and post-operatively. The mean fluorescence intensity (MFI) of the tumor was calculated for each specimen at each imaging time point. Adjacent normal tissue served as an internal anatomic control for each patient to establish a patient-matched "background" fluorescence. Resected tissues were also imaged using a closed-field NIR imaging device. Tumor to background ratios (TBRs) were calculated for each patient using both devices. Fluorescence histology was correlated with traditional pathology assessment to verify the specificity of antibody-dye conjugate binding. Peak TBRs using the open-field device ranged from 2.2 to 11.3, with an average TBR of 4.9. Peak TBRs were achieved between days 1 and 4. This study demonstrated that a commercially available NIR imaging device suited for intraoperative and clinical use can successfully be used with a fluorescently-labeled dye to delineate between diseased and normal tissue in this single cohort human study, illuminated the potential for its use in fluoresence-guided surgery.

  1. Papillary renal cell carcinoma

    International Nuclear Information System (INIS)

    Between 1976 and 1987, 395 patients with kidney tumors were studied with radiological techniques and sonography. In 37 cases (9.4%) histopathology diagnosed pure papillary renal cell carcinoma. Analyzing the radiographic patterns of these neoplasms, the authors observed constantly diminished vascularity (100%) frequent calcifications (35.1%) and necrotic areas (51.3%). Such X-ray features are not specific: nevertheless, their coexistence is strongly suggestive of papillary renal cell cancer. No consistent US pattern was found; however, necrotic areas were easily demonstrated in most cases. It must be stressed how patients with papillary carcinoma experienced a longer post-operative survival; it has not yet been established whether such favorable behavior is due to low biological aggressiveness or to earlier diagnosis

  5. Immunotherapy in renal cell carcinoma.

    Bukowski, R M

    1999-06-01

    Patients with metastatic renal cell carcinoma continue to present a therapeutic challenge. Current therapeutic approaches involve surgery and various types of immunotherapy. The rationale for this latter form of therapy include the observations of spontaneous tumor regression, the presence of a T-cell-mediated immune response, and the tumor responses observed in patients receiving cytokine therapy. Analysis of prognostic factors in these patients demonstrates that clinical responses occur most frequently in individuals with good performance status. The cytokines interleukin-2 (IL-2, aldesleukin [Proleukin], interferon-alfa (Intron A, Roferon-A), or the combination produce responses in 15% to 20% of patients. Randomized trials suggest that administration of interferon-alfa may result in a modest improvement in median survival. Investigation of the molecular genetics of renal cell carcinoma and the presence of T-lymphocyte immune dysregulation have suggested new therapeutic strategies. Further preclinical and clinical studies investigating inhibitors of angiogenesis or pharmacologic methods to reverse immune dysregulation are ongoing. Therapeutic results in patients with renal cell carcinoma remain limited, and investigational approaches are warranted. PMID:10378218

    Full Text Available Abstract Pilomatrix carcinoma is the rare malignant counterpart of pilomatrixoma, a skin adnexal tumour originating from hair matrix cells. Pilomatrix carcinoma can arise as a solitary lesion de novo, or through transformation of a pilomatrixoma. Pilomatrixoma was first described erroneously as being of sebaceous gland origin but was later discovered to be derived from hair matrix cells. They are rare, slow growing tumours of the skin found in the lower dermis and subcutaneous fat and are predominantly found in the neck and the scalp. While known to be locally aggressive, no malignant form was thought to exist until it was described relatively recently. Since then, approximately ninety cases of pilomatrix carcinoma have been reported. We report the case of a 41 year old mentally retarded male who had a longstanding lesion in the left neck for approximately fifteen years previously diagnosed as a pilomatrixoma. He presented with severe headache, falls and visual disturbance and a biopsy showed pilomatrix carcinoma of the occipital region which, on computed tomography ( CT invaded the occipital bone, the cerebellum and the left temporal lobe. At his initial presentation he had a craniotomy and subtotal excision of the lesion but received no adjuvant therapy. After an early intracranial recurrence he had further debulking and adjuvant external beam radiotherapy. He has had no further intracranial recurrence after three and a half years of follow-up. Here we present the pathological features of this uncommon tumour.

    Full Text Available Thyroid surgeons are becoming increasingly more aware of a histologically distinct subset of thyroid carcinoma whose classification falls between well-differentiated and anaplastic carcinomas with respect to both cell differentiation and clinical behavior. This subtype of tumors has been categorized as poorly differentiated or insular carcinoma, based on its characteristic cell groupings. Although the differentiation of insular carcinoma from other thyroid carcinomas has important prognostic and therapeutic significance, relatively little about insular carcinoma has been published in the otolaryngology literature. In this article, we discuss a case of insular carcinoma of thyroid presenting with concurrent distant metastasis to skull, lung, ribs, and inguinal region with review of the literature. We conclude that insular thyroid carcinoma warrants aggressive management with total thyroidectomy and excision of accessible giant lesion followed by radioactive iodine ablation of any remaining thyroid tissue.

  1. Small cell carcinoma of the urinary bladder

    International Nuclear Information System (INIS)

    Small cell carcinoma of the urinary bladder (SCCUB) is an extremely rare tumor that exhibits aggressive behavior and accounts for approximately less than 1% of all primary bladder tumors. Small cell carcinoma generally occurs in the lung, accounting for 25% of all pulmonary malignancies. SCCUB exhibits a similar microscopic and immunohistochemical appearance to that of small cell carcinoma of the lung. There is no consensus about the standard therapy, owing to its rarity. Surgical resection seems to be the mainstay of treatment for patients with limited stage, together with neoadjuvant or adjuvant platinum-based chemotherapy. Radiation therapy has same small effect for palliative purposes, as well as being an alternative to radical cystectomy. Patients with advanced stage, although given platinum-based chemotherapy, have a poor prognosis. We herein review epidemiology, clinical presentation, diagnosis, pathological features, and current management of small cell carcinoma of the urinary bladder. (author)

  2. Planoepitheliale cell carcinoma arising from ampullopancreatic unit

    International Nuclear Information System (INIS)

    Background: We report a case of planoepitheliale cell carcinoma located in the ampulla of Vater. We report the surgical results and pathological findings of a patient with an ampullary planoepitheliale cell carcinoma. From what we know it is the first case with successful surgical treatment. Case Report: A 58-year-old woman who presented with jaundice and preoperative endoscopic and radiological procedures could not show whether the tumour was carcinoma planoepitheliale. The clinical presentation, biochemical, radiographic and endoscopic investigation pronounced advanced pancreatic adenocarcinoma. Results: We performed pancreaticoduodenectomy with curative intention. Histological examination revealed: planoepitheliale cell carcinoma of the ampullo-pancreatic unit. Conclusions: In conclusion, preoperative endoscopic and radiological evaluations can all prove insufficient to distinguish between benign and malignant tumour. Thus, for malignant tumours surgeons may be forced to perform extensive surgery. (authors)

    Full Text Available Tumors of the nasosinuous tract developed in the air cavities usually present a considerable growing before the patient feel any symptom or sign. Great part of the symptomatology is given due to the invasion of the tumor to neighbour structures such as oral and nasal cavities and orbits. A case of a 62 year-old male patient is presented after being under a dental extraction. A bucco-sinuous communication was diagnosed. It did not respond to different treatments and after some moths an epidermoid carcinoma of the right maxillary sinus appeared. It is of great interest to let this case been known in order to outstand the importance of an early diagnosis to get a better vital prognosis in this kinds of lesions.

    Full Text Available Xanthogranulomatous endometritis (XGE is an uncommon but well-established histopathological entity seen affecting the kidney and gallbladder. Involvement of the endometrium is very rare, with only a few case reports in world literature till date. Histologically, it is characterized by the replacement of the endometrium by sheets of foamy histiocytes, plasma cells, lymphocytes, giant cells, and siderophages. We present a case of a 74-year-old female who presented with foul-smelling discharge and postmenopausal bleeding of a short duration. Clinical examination and imaging studies revealed a pyometra, cervical stenosis. A suspicion of carcinoma was raised. Since XGE may mimic an endometrial carcinoma clinically and pathologically, knowledge of this unusual and rare inflammatory pathology is important for both the gynecologists and the pathologists.

    We present protoporphyrin IX (PpIX) fluorescence measurements acquired from patients presenting with superficial basal cell carcinoma during photodynamic therapy (PDT) treatment, facilitating in vivo photobleaching to be monitored. Monte Carlo (MC) simulations, taking into account photobleaching, are performed on a three-dimensional cube grid, which represents the treatment geometry. Consequently, it is possible to determine the spatial and temporal changes to the origin of collected fluorescence and generated singlet oxygen. From our clinical results, an in vivo photobleaching dose constant, β of 5-aminolaevulinic acid-induced PpIX fluorescence is found to be 14 +/- 1 J/cm2. Results from our MC simulations suggest that an increase from our typical administered treatment light dose of 75-150 J/cm2 could increase the effective PDT treatment initially achieved at a depth of 2.7-3.3 mm in the tumor, respectively. Moreover, this increase reduces the surface PpIX fluorescence from 0.00012 to 0.000003 of the maximum value recorded before treatment. The recommendation of administrating a larger light dose, which advocates an increase in the treatment time after surface PpIX fluorescence has diminished, remains valid for different sets of optical properties and therefore should have a beneficial outcome on the total treatment effect.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    2011-04-01

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

    A multifocal biphasic squamoid alveolar renal cell carcinoma in a 68-year-old man is reported. Four different peripheral tumor nodules were identified on gross examination. A fifth central tumor corresponded to a conventional clear cell renal cell carcinoma. Biphasic squamoid alveolar renal cell carcinoma is a rare tumor that has been very recently characterized as a distinct histotype within the spectrum of papillary renal cell carcinoma. Immunostaining with cyclin D1 seems to be specific of this tumor subtype. This is the first reported case with multifocal presentation. PMID:27158455

    International Nuclear Information System (INIS)

    Objective: To analyze MRI manifestation and enhancement of renal cell carcinoma, and to improve the diagnosis of renal cell carcinoma. Methods: 48 cases of renal cell carcinoma proven by surgery and pathology were reviewed. MRI scans including T1WI, T2WI, TRUFI and contrast enhancement were carried out in all cases and dynamic contrast-enhanced MRI was performed in 15. Results: Of the 48 cases, there were clear cell carcinoma in 41, chromophobe cell carcinoma in 4 and papillary cell carcinoma in 3. The tumors were homogeneously T1 iso- or hypointense in 33 and heterogeneous in 15; homogeneously T2 hyperintense in 14, isointense in 6 and heterogeneous in 28 patients. Pseudocapsule was found in 10 cases. Contrast enhancement was homogeneous in 6, heterogeneous in 34, irregularly peripheral within the wall in 5, and homogeneously circular in 3. Conclusion: MRI can accurately diagnose renal cell carcinoma and help to determine the cell subsets. (authors)

    2009-06-01

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid. PMID:26589365

    An eight-year-old, neutered male Burmese cat presented with five days vomiting and anorexia. Physical examination, clinical pathology and diagnostic imaging findings suggested a perirenal pseudocyst. After partial resection of the perirenal capsule clinical signs temporarily resolved, but the cat was euthanased 34 days postoperatively as a result of seizures and recurrence of vomiting. Postoperative histopathology showed neoplastic transitional cells within and lining the resected perirenal capsule; a diagnosis of transitional cell carcinoma was confirmed post-mortem. To the authors' knowledge, this is the first report of this presentation of transitional cell carcinoma. Transitional cell carcinoma should be a differential diagnosis for the aetiology of perirenal pseudocyst. PMID:17784930

    associated with its cause. However, other elements of risk are described, such as light skin phototypes, advanced age, family history of skin carcinoma, light eyes and blond hair, freckles in childhood and immunosuppression. Behavioral aspects such as occupational sun exposure, rural labor and sunburns at a young age also play a role. Between 30% and 75% of the sporadic cases are associated with patched hedgehog gene mutation, but other genetic changes are also described. The tumor is commonly found in concomitance with skin lesions related to chronic sun exposure, such as actinic keratoses, solar lentigines and facial telangiectasia. The prevention of basal cell carcinoma is based on the knowledge of risk factors, early diagnosis and treatment, as well as on the adoption of specific measures, particularly in susceptible populations. The authors present a review of the epidemiology of basal cell carcinoma.

    Our knowledge of renal cell carcinoma (RCC) is rapidly expanding. For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC. PMID:24364021

    Full Text Available Carcinoma en cuirasse is a form of cutaneous metastasis. Although this condition is rare, it is most commonly associated with breast carcinoma with local recurrence after mastectomy. Cutaneous metastasis presents most commonly a few months or years after the primary has been diagnosed. Less frequently a metastasis is diagnosed at the same time as the primary tumor or presents as the first manifestation of the disease. We report a case of carcinoma en cuirasse in a 50-year-old female who presented with elevated, finely nodular, indurated skin lesions on left anterior chest wall, axillary region and keloid - like patch on left upper arm. On further examination a breast mass was detected. Fine needle aspiration of all the lesions was performed. Cytodiagnosis was given as infiltrating duct carcinoma of breast with metastatic carcinoma involving left anterior chest wall, axilla and left upper arm. We should not disregard keloid-like or indurated patches on skin which should be investigated thoroughly.

  4. CT feature analysis of renal cell carcinoma: report of 300 cases

    International Nuclear Information System (INIS)

    Objective: To analyze the CT features of renal cell carcinoma, so as to improve the diagnostic accuracy of renal cell carcinoma. Methods: Three hundred cases of renal cell carcinoma proved by pathology were examined by means of CT. There were 214 male and 86 female in this group. Their age ranged from 9 to 81 years, with a mean of 53.7 years. Their CT features were retrospectively reviewed. Results: The masses were 1.5-16.0 cm (mean, 4.8 cm) in greatest dimension, 125 masses on left kidney and 175 masses on right kidney. According to WHO histological classification of tumours of the kidney in 2004, there were 238 cases of clear cell renal cell carcinoma, 6 cases of multilocular clear cell renal cell carcinomas, 23 cases of papillary renal cell carcinoma, 14 cases of chromophobe renal cell carcinoma and 19 eases of renal cell carcinoma, unclassified. The above subtype of renal cell carcinoma demonstrated characteristic features. Clear cell renal cell carcinoma exhibited inhomogenous (due to hemorrhage, necrosis or cystic degeneration) and hypervascular. Multilocular clear cell renal cell carcinoma presented as a multilocular cystic mass lacking an expansile nodule, and with regular thin cyst wall and septa. Papillary renal cell carcinoma exhibited inhomogenous and hypovascular. Chromophobe renal cell carcinoma was relatively homogenous and hypovascular. Renal cell carcinoma, unclassified showed inhomogenous and hypervascular, and was more invading growth compared to clear cell renal cell carcinoma. Conclusion: Common subtype of renal cell carcinoma demonstrated characteristic features in CT and it is helpful for differentiation. (authors)

    Full Text Available We previously published our and Johns Hopkins data titled: "Platinum-based therapy in adenosquamous pancreatic cancer: experience at two institutions” [1]. We will here like to submit a related case report as a letter to the editor to JOP in reference to the above paper. Squamous cell carcinoma of the pancreas has various reported incidence rates, ranging from 0.5% to as high as 5% of pancreatic ductal carcinomas [2, 3]. Of the 1300 cases of pancreatic cancers observed at autopsy in a survey in Japan in 1992, 0.7% were squamous cell carcinoma [4]. A Mayo clinic review of very rare exocrine tumors showed an even rarer incidence of squamous cell carcinoma when compared to acinar and small cell carcinoma of the pancreas [5]. This discrepancy in the reported incidence rates related to the fact that some of the cases represent adenosquamous carcinoma rather than pure squamous cell carcinoma of pancreas. In an analysis of 25 patients, mean age at diagnosis of pancreatic squamous cell carcinoma was 62 years (range: 33–80 years and there was no gender difference [6]. There is no study about the molecular profile of squamous carcinoma of the pancreas. There are no retrospective or prospective studies about the best therapy for these tumors

    2015-08-01

    Small cell lung carcinoma (SCLC) commonly metastasizes to distant organs. However, metastasis to the pancreas is not a common event. Moreover, obstructive jaundice as a first clinical presentation of SCLC is extremely unusual. This case reports a 51-year-old male with SCLC, manifesting with obstructive jaundice as the initial clinical presentation. Endoscopic retrograde cholangiopancreatograghy (ERCP) and abdominal computed tomography (CT) scan showed a mass at the head of the pancreas. The patient underwent pancreatoduodenectomy (Whipple procedure). Histopathology revealed a chromogranin- A-positive poorly-differentiated neuroendocrine carcinoma of the pancreas. No imaging study of the lung was performed before surgery. A few months later, a follow-up CT revealed unilateral lung nodules with ipsilateral hilar nodes. A lung biopsy was done and histopathology reported a TTF- 1-positive, chromogranin A-positive, small cell carcinoma of the lung. On review, the pancreatic tumour was also TTF-1-positive. He was then treated with combination chemotherapy (cisplatin, etoposide). These findings highlight that presentation of a mass at the head of pancreas could be a manifestation of a metastatic tumour from elsewhere such as the lung, and thorough investigations should be performed before metastases can be ruled out.

    Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    Full Text Available Spindle cell carcinoma (SpCC is a unique variant of squamous cell carcinoma (SCC. SpCC confined to the nasal cavity is extremely rare, with only one case having been previously reported. We present a case report of nasal cavity SpCC and review the literature on this rare entity. A 29-year-old male presented with intermittent epistaxis from the left nasal cavity. On physical examination, the patient had an ulcerated mass in the left nasal vestibule and a biopsy showed a proliferation of spindle and epitheliod cells. The patient underwent wide local excision of the mass via a lateral alotomy approach and reconstruction with a composite conchal bowl skin and cartilage graft. Histologically, the mass had dyplastic squamous epithelium and spindle-shaped cells admixed with epitheliod cells. Immunohistochemistry was only positive for pancytokeratin AE1/AE3 and vimentin. Six months after surgery, the patient continues to have no evidence of disease. On literature review, only one previous case of SpCC confined to the nasal cavity was identified. We present a rare case of nasal cavity SpCC. No definite treatment protocol exists for this unique entity, but we believe that this tumor should primarily be treated with aggressive, wide local excision. Adjuvant radiation and/or chemotherapy have also been used anecdotally.

    2009-02-01

    Full Text Available Abstract Renal cell carcinoma constitutes about 3% of adult malignancies. It has a high metastatic potential associated with synchronous or metachronous metastatic disease. Further, it is known to metastasize mainly to the lung, bone, brain, liver, or adrenal glands. In very rare cases it can metastasize to the gallbladder mimicking acute cholecystitis on clinical exam. In this case we present a patient who developed a gallbladder metastasis five years after a renal cell carcinoma mimicking acute cholecystitis.

    Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year’s duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up. PMID:26629388

    Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169

  1. Interaction of Stellate Cells with Pancreatic Carcinoma Cells

    International Nuclear Information System (INIS)

    Pancreatic cancer is characterized by its late detection, aggressive growth, intense infiltration into adjacent tissue, early metastasis, resistance to chemo- and radiotherapy and a strong “desmoplastic reaction”. The dense stroma surrounding carcinoma cells is composed of fibroblasts, activated stellate cells (myofibroblast-like cells), various inflammatory cells, proliferating vascular structures, collagens and fibronectin. In particular the cellular components of the stroma produce the tumor microenvironment, which plays a critical role in tumor growth, invasion, spreading, metastasis, angiogenesis, inhibition of anoikis, and chemoresistance. Fibroblasts, myofibroblasts and activated stellate cells produce the extracellular matrix components and are thought to interact actively with tumor cells, thereby promoting cancer progression. In this review, we discuss our current understanding of the role of pancreatic stellate cells (PSC) in the desmoplastic response of pancreas cancer and the effects of PSC on tumor progression, metastasis and drug resistance. Finally we present some novel ideas for tumor therapy by interfering with the cancer cell-host interaction

    International Nuclear Information System (INIS)

    Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor, significantly different from generic hepatocellular carcinoma with distinct demographics, risk factors, imaging features, histopathology and prognosis. Unlike conventional hepatocellular carcinoma, it presents in young individuals with no preexisting hepatitis or cirrhosis and does not cause elevation of serum alpha feto proteins in most cases. This paper presents a case report of this rare tumor in a young female with an unusual clinical manifestation of obstructive jaundice (which has not been reported so far) along with a review of its imaging and pathological features, with treatment options. Fibrolamellar HCC is a rare variant of classic HCC with different epidemiology, risk factors, clinical manifestations, radiological, pathological and prognostic features. Therefore, it is important to be familiar with the entity for its early diagnosis and management

    2004-12-01

    Renal cell carcinoma accounts for 2-3% of all malignancies. The most common subtype [85%] is the clear cell variant. A total of 30% of patients present with metastatic disease at diagnosis and another 30-40% will develop metastases during the course of the disease. Conventional cancer treatment is not effective, but cytokines including recombinant interleukin-2 (aldesleukin) have demonstrated clinical activity of various degrees. This drug profile provides a review of the literature on studies using aldesleukin in patients with metastatic renal cell carcinoma. Aldesleukin has been used in different dose schedules applying various administration routes, as either monotherapy or in combination with other cytokines, chemotherapy, endocrine treatment and adoptive cellular immunotherapy. Although a large number of randomized trials have been performed with different treatment strategies, it still remains uncertain whether the dose or combination of aldesleukin with other agents substantially influence treatment outcome. It appears that factors other than those that are treatment related are responsible for the course of the disease. PMID:15606326

    Merkel cell carcinoma (MCC) is an aggressive poorly differentiated neuroendocrine cutaneous carcinoma associated with older age, immunodeficiency and Merkel cell polyomavirus (MCPyV) integrated within malignant cells. The presence of intra-tumoural CD8+ lymphocytes reportedly predicts better MCC-specific survival. In this study, the distribution of inflammatory cells and properties of CD8+ T lymphocytes within 20 primary MCC specimens were characterised using immunohistochemistry and multicolour immunofluorescent staining coupled to confocal microscopy. CD8+ cells and CD68+ macrophages were identified in 19/20 primary MCC. CD20+ B cells were present in 5/10, CD4+ cells in 10/10 and FoxP3+ cells in 7/10 specimens. Only two specimens had almost no inflammatory cells. Within specimens, inflammatory cells followed the same patchy distribution, focused at the edge of sheets and nodules and, in some cases, more intense in trabecular areas. CD8+ cells were outside vessels on the edge of tumour. Those few within malignant sheets typically lined up in fine septa not contacting MCC cells expressing MCPyV large T antigen. The homeostatic chemokine CXCL12 was expressed outside malignant nodules whereas its receptor CXCR4 was identified within tumour but not on CD8+ cells. CD8+ cells lacked CXCR3 and granzyme B expression irrespective of location within stroma versus malignant nodules or of the intensity of the intra-tumoural infiltrate. In summary, diverse inflammatory cells were organised around the margin of malignant deposits suggesting response to aberrant signaling, but were unable to penetrate the tumour microenvironment itself to enable an immune response against malignant cells or their polyomavirus

    Merkel cell carcinoma (MCC) is an aggressive poorly differentiated neuroendocrine cutaneous carcinoma associated with older age, immunodeficiency and Merkel cell polyomavirus (MCPyV) integrated within malignant cells.

    Renal solitary extramedullary plasmacytomas belong to a group of plasma cell neoplasms, which generally have been associated with renal cell carcinoma. We present a case report of a patient with collision tumor histology of extramedullary plasmacytoma and clear cell renal cell carcinoma, the first in the known literature. Standard work-up for a plasma cell neoplasm was conducted and the mass was resected. The patient remains disease-free at 28 months post-surgery. The report calls into question pre-surgical renal mass biopsy protocol and suggests a relationship between renal cell carcinoma and plasma cell neoplasms. PMID:27175345

    Full Text Available Distant metastasis may be the initial sign of differentiated thyroid carcinoma in rare cases. In this instance, the treatment approach is usually individualized. Unlike most other cancers, local treatment of the primary tumor (total thyroidectomy is preferred as ablative surgery; so that radioactive iodine therapy should be more effective. Repeated doses of I-131 and radiotherapy for metastatic lesions may be needed. We report a female who presented with bone metastasis with fatal progression. Turk Jem 2013; 17: 71-4

    Full Text Available Hepatocellular carcinoma (HCC represents the fifth most common cancer in the world, and the third most frequent oncological cause of death. The incidence of HCC is on the increase. HCC typically develops in patients with chronic liver diseases, and cirrhosis, usually with viral etiology, is the strongest predisposing factor. Nowadays HCC diagnosis is a multistage process including clinical, laboratory, imaging and pathological examinations. The prognosis of HCC is mostly poor, because of detection at an advanced, non-resectable stage. Potentially curative treatment (surgery is limited and really possible only for cases with small HCC malignancies. For this reason, more effective surveillance strategies should be used to screen for early occurrence of HCC targeted to the population at risk. So far, the generally accepted serological marker is α-fetoprotein (AFP. Its diagnostic accuracy is unsatisfactory and questionable because of low sensitivity, therefore there is a strong demand by clinicians for new HCC-specific biomarkers. In this review, we will focus on other biomarkers that seem to improve HCC diagnosis, such as AFP-L3, des-γ-carboxyprothrombin, α-l-fucosidase, γ-glutamyl transferase, glypican-3, squamous cell carcinoma antigen, a new generation of immunoglobulin M-immunocomplexes, and very promising gene-expression profiling.

    2014-10-01

    Full Text Available Hashimoto’s thyroiditis, the most common autoimmune thyroid disease, is due to destruction of the thyroid gland by autoantibodies. Various types of thyroid malignancies may arise in Hashimoto’s thyroiditis. Follicular carcinomas, papillary carcinomas, lymphomas, medullary carcinomas and hurthle cell neoplasms may develop in Hashimoto’s thyroiditis. We present a rare case report of a 35-year-old female who presented with hypothyroidism of a two-year duration. A diagnosis of Hashimoto’s thyroiditis was made for which she was under treatment. Due to the recent increase in size of the thyroid, a fine needle aspiration cytology was done. A preoperative diagnosis of Hurthle cell neoplasm was made based on fine needle aspiration cytology findings. The total thyroidectomy specimen revealed Hashimoto’s thyroiditis with synchronous papillary carcinoma and Hurthle cell carcinoma, which is a very rare occurrence.

    Penile clear cell carcinoma originating in skin adnexal glands has been previously reported. Here, we present 3 morphologically distinctive penile tumors with prominent clear cell features originating not in the penile skin but in the mucosal tissues of the glans surface squamous epithelium. Clinical and pathologic features were evaluated. Immunohistochemical stains were GATA3 and p16. Human papilloma virus (HPV) detection by in situ hybridization was performed in 3 cases, and whole-tissue section-polymerase chain reaction was performed in 1 case. Patients' ages were 52, 88, and 95 years. Tumors were large and involved the glans and coronal sulcus in all cases. Microscopically, nonkeratinizing clear cells predominated. Growth was in solid nests with comedo-like or geographic necrosis. Focal areas of invasive warty or basaloid carcinomas showing in addition warty or basaloid penile intraepithelial neoplasia were present in 2 cases. There was invasion of corpora cavernosa, lymphatic vessels, veins, and perineural spaces in all cases. p16 was positive, and GATA3 stain was negative in the 3 cases. HPV was detected in 3 cases by in situ hybridization and in 1 case by polymerase chain reaction. Differential diagnoses included other HPV-related penile carcinomas, skin adnexal tumors, and metastatic renal cell carcinoma. Features that support primary penile carcinoma were tumor location, concomitant warty and/or basaloid penile intraepithelial neoplasia, and HPV positivity. Clinical groin metastases were present in all cases, pathologically confirmed in 1. Two patients died from tumor dissemination at 9 and 12 months after penectomy. Clear cell carcinoma, another morphologic variant related to HPV, originates in the penile mucosal surface and is probably related to warty carcinomas. PMID:26848799

    Full Text Available Endometriosis is a common benign disease of reproductive age women, and can involve the intestinal tract. Inconsistent clinical presentation, similar features on radiological imaging and colonoscopy with other inflammatory and malignant lesions of the bowel makes the preoperative diagnosis of bowel endometriosis difficult. We present a case of a 42-year-old perimenopausal female clinically presented, investigated and managed in the lines of carcinoma of sigmoid colon. She underwent terminal ileac resection with end to end anastomoses, Hartmann′s procedure and total hysterectomy with bilateral salpingoophorectomy. The histopathological report revealed endometriosis of small intestine, large intestine, mesentery, right ovary and adenomyoma of uterus. Thus, bowel endometriosis should also be considered as differential diagnosis in reproductive age women with gastrointestinal symptoms or intestinal mass of uncertain diagnosis.

    Full Text Available Oral squamous cell carcinoma accounts for 90% to 95% of all oral malignancies. Though its diagnosis seldom presents difficulty, it is the cancer staging and histopathological grading that are important to prognostication; and micronuclei are good prognostic indicators. Micronucleus frequencies in oral exfoliated cells stained with papanicolaou stain were counted and correlated with the histopathological grades and clinical stages of squamous cell carcinoma patients. They were also compared with healthy control subjects. Micronuclei (MN frequencies were found higher in squamous cell carcinoma patients than in control subjects. MN frequencies were also found to be raised with increasing histological grades of squamous cell carcinoma.

    The vermilion and vermilion border are rare locations for basal cell carcinoma. We report a case of a 72-year-old woman, who presented with an asymptomatic erosive lesion on the vermilion area of the upper lip. Histopathology examination was consistent with basal cell carcinoma. We suggest that basal cell carcinoma should be included in the differential diagnosis of erosive/ulcerative lesions arising on the vermilion area of the lip.

  11. A Novel Protein Is Lower Expressed in Renal Cell Carcinoma

    Full Text Available Engrailed-2 (EN2 has been identified as a candidate oncogene in breast cancer and prostate cancer. It is usually recognized as a mainly nuclear staining in the cells. However, recent studies showed a cytoplasmic staining occurred in prostate cancer, bladder cancer and clear cell renal cell carcinoma. The inconsistency makes us confused. To clarify the localization and expression of EN2 in renal cell carcinoma, anti-EN2 antibody (ab28731 and anti-EN2 antibody (MAB2600 were used for immunohistochemistry (IHC respectively. Interestingly, we found that EN2 detected by ab28731 was mainly presented in cytoplasm while EN2 detected by MAB2600 was mainly presented in nucleus. To further investigate the different patterns observed above, lysates from full-length EN2 over expression in HEK293T cells were used to identify which antibody the EN2 molecule bound by western blot. Results showed ab28731 did not react with the lysates. For this reason, the novel specific protein detected by ab28731 was not the EN2 molecule and was named nonEN2. Then using the renal carcinoma tissue microarray and renal tissues, we found that the protein expression levels of nonEN2 in kidney tumor tissues was significantly lower than that in kidney normal tissues (p < 0.05, so was in renal cell lines. Taken together, nonEN2 is lower expressed and may play an important role in renal cell carcinoma.

    Full Text Available Abstract Background Bladder small cell carcinoma is an uncommon tumour. Through a retrospective study we will present the evolution of recurrent and metastatic disease and outcome of patients treated at Léon-Bérard Cancer Centre. Methods Only 15 patients having recurrent or metastatic bladder small cell carcinoma were treated at Léon-Bérard Cancer Centre between 1996 and 2007. The patients were divided in two groups: a mixed small cell carcinoma group (9 patients and a pure small cell carcinoma group (6 patients. All the records and informations related to treatment and outcome of the 15 patients were retrospectively analyzed. Various characteristics of small cell carcinoma were investigated. Results The median age of the 15 patients having recurrent or metastatic bladder small cell carcinoma and treated at Léon-Bérard Cancer Centre was 63 years and the disease was at stage IV for all cases. Nine patients were treated by chemotherapy. Four patients were treated by local radiotherapy (3 with radiotherapy without previous surgery and 1 with surgery followed by radiotherapy and chemotherapy. One patient was treated by whole brain radiotherapy. And one patient died before treatment. After 52.4 months median follow up, 12 patients died. Median overall survival was 7.6 months. Survival probability at 1 year was 33%. Median overall survival was 9.9 months in the mixed small cell carcinoma group, and was only 4.6 months in the pure small cell carcinoma group. Survival probability at 1 year in the mixed small cell carcinoma group was 44% as compared to 17% in the pure small cell carcinoma group (Log-rank test: p = 0.228. Conclusion Recurrent and metastatic bladder small cell carcinoma is associated with very poor prognosis. The pure bladder small cell carcinoma appears to have poorer outcome than the mixed bladder small cell carcinoma. Chemotherapy using platinum drugs is a mainstay treatment.

    Full Text Available Basal cell carcinoma (BCC is the most frequent non-melanoma skin cancer. Only 5-15% of BCC cases can be found in patients aged 20-40 years (so-called early onset. The early onset BCC is characterized by active and aggressive tumour growth, clinically presenting in most of the cases as a morpheaform, locally infiltrating or recurrent BCC. Despite the advances in the study of the pathogenesis of this tumour, surgery remains the most used, most effective and most suitable treatment modality. We describe a case of a 39-year-old woman who developed an early onset BCC of the nasolabial fold. After the subsequent surgical excision an excellent cosmetic result was achieved.

    International Nuclear Information System (INIS)

    The dystrophic form of hereditary epidermo-lysis bullosa is associated with an increased frequency of squamous cell carcinoma. We report a new case. An 18-year-old patient, carrying a Hallopeau Siemens hereditary epidermo-lysis bullosa, presented a subcutaneous nodular lesion, for 1 year that ulcerated and budded with inguinal lymphadenopathy. The histological study ted to the conclusion of a well differentiated squamous cell carcinoma. The patient was treated surgically. Tumor and metastatic lymph nodes were excised. A radiotherapy was decided but the postoperative course was fatal due to an infection and to a deterioration of her general condition. Squamous cell carcinoma frequently occurs on the cicatricial lesion of hereditary epidermo-lysis bullosa and usually affects males with recessive hereditary epidermo-lysis bullosa. Metastases are frequent, precocious and multiple. The treatment may be surgical. The particularities of our observation are the young age of patient and the localization. (author)

    Full Text Available Tumors of nail unit may be benign or malign. Different histological variants of subungual tumours have been reported. Subungual squamous cell carcinoma is rare, and the disease is often misdiagnosed as a benign condition, therefore it is difficult to estimate the real incidence of this disease. We hereby present a case of subungual squamous cell carcinoma that has previously been treated as leading to a delay in diagnosis and treatment. For this reason, the nail unit changes should be examined carefully and the diagnosis should be done with the histopathological examinations. Proper treatment should be planned according to the histopathological diagnosis.

    Congenital anomalies of the kidney and urinary tract are common and include a wide anatomic spectrum. Duplex systems are one of the more common renal anomalies, with the majority being asymptomatic. Little is known about the molecular pathogenesis of these anomalies; however, certain causative genes have been implicated. The finding of renal cell carcinoma arising in a kidney with the duplication of pelvicalyceal system and ureters, as in the present case, is uncommon. The association between a duplex system and renal cell carcinoma may be more than a coincidence, requiring a deeper insight and further elucidation. PMID:26328175

    Full Text Available Cutaneous squamous cell carcinoma of the ear represents a high-risk tumor location with an increased risk of metastasis and local tissue invasion. However, it is uncommon for these cancers to invade through nearby cartilage. Cartilage invasion is facilitated by matrix metalloproteases, specifically collagenase 3. We present the unusual case of a 76-year-old man with an auricular squamous cell carcinoma that exhibited full-thickness perforation of the scapha cartilage. Permanent sections through the eroded cartilage confirmed tumor invasion extending to the posterior ear skin.

Case: This is the case of a 49-year-old man diagnosed with squamous cell carcinoma of the face, scheduled for resection. Preoperative radiographs revealed a left upper lobe mass, found to be squamous cell carcinoma. Diagnosis was changed to Stage IV primary lung cancer. The patient did not undergo resection. Discussion: No previous cases of primary lung cancer presenting as a malar mass have been reported. Facial lesions can be the presenting feature of primary lung cancer. Discovery of the true primary lesion can alter therapy and prognosis.

    Clear cell carcinoma of the thymus is a rare tumor. Few cases of clear-cell carcinoma of thymus have been documented (Truong et al., 1990 and Wolfe III et al., 1983). All these cases were diagnosed by histopathological examination of the tissue. Diagnosis of thymic clear cell carcinoma on cytology is extremely challenging. Here we report the first case of thymic clear cell carcinoma diagnosed by cytological examination of the pericardial fluid with the help of immunocytochemistry. Differentia...

    According to the cancer stem cell hypothesis tumors are maintained by a cancer stem cell population which is able to initiate and maintain tumors. Tumor-initiating stem cells display stem or progenitor cell properties such as self-renewal and capacity to re-establish tumors that recapitulate the tumor of origin. In this paper, we discuss data relative to the presence of cancer stem cells in human renal carcinoma and their possible origin from normal resident stem cells. The cancer stem cells ...

    2007-01-01

    Malignant fibrous histiocytoma (MFH) is a pleomorphic mesenchynal sarcoma. It is uncommonly arises primarily from the intra-peritoneal cavity. Primary peritoneal MFH with tumor bleeding and rupture is rare. We describe the imaging features of a 70-year-old patient presenting with ruptured hemorrhagic peritoneal MFH at subhepatic area, accompanied by massive hemoperitoneum,mimicking a ruptured pedunculated hepatocellular carcinoma. Computed tomography (CT) revealed a large heterogeneous enhanced subhepatic mass with adjacent liver, gallbladder and colon invasion. Tumor hemorrhage and rupture complicated with peritoneal seeding and massive bloody ascites were also detected.Angiography showed a hypervascular tumor fed by enlarged right hepatic arteries, cystic artery and omental branches of gastroepiploic artery. The patient underwent laparotomy for tumor resection, but the tumor recurred one month after operation. To our knowledge, the CT appearance of ruptured intraperitoneal MFH complicated by hemoperitoneum has not been previously described.

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

    Highlights: •Nesfatin-1 inhibits the proliferation and growth of HO-8910 cells by G1 phase arrest. •Nesfatin-1 enhances HO-8910 cell apoptosis. •Nesfatin-1 inhibits HO-8910 cell proliferation via mTOR and RhoA/ROCK signaling pathway. •The first report of nesfatin-1-mediated proliferation in ovarian epithelial carcinoma. -- Abstract: Nesfatin-1, an 82-amino-acid peptide derived from a 396-amino-acid precursor protein nucleobindin 2 (NUCB2), was originally identified in hypothalamic nuclei involved in the regulation of food intake. It was recently reported that nesfatin-1 is a novel depot specific adipokine preferentially produced by subcutaneous tissue, with obesity- and food deprivation-regulated expression. Although a relation between ovarian cancer mortality and obesity has been previously established, a role of nesfatin-1 in ovarian epithelial carcinoma remains unknown. The aim of the present study is to examine the effect of nesfatin-1 on ovary carcinoma cells proliferation. We found that nesfatin-1 inhibits the proliferation and growth of HO-8910 cells by G1 phase arrest, this inhibition could be abolished by nesfatin-1 neutralizing antibody. Nesfatin-1 enhances HO-8910 cell apoptosis, activation of mammalian target of rapamycin (mTOR) and RhoA/ROCK signaling pathway block the effects of nesfatin-1-induced apoptosis, therefore reverses the inhibition of HO-8910 cell proliferation by nesfatin-1. In conclusion, the present study demonstrated that nesfatin-1 can inhibit the proliferation in human ovarian epithelial carcinoma cell line HO-8910 cells through inducing apoptosis via mTOR and RhoA/ROCK signaling pathway. This study provides a novel regulatory signaling pathway of nesfatin-1-regulated ovarian epithelial carcinoma growth and may contribute to ovarian cancer prevention and therapy, especially in obese patients.

    The traditional view that adult human liver tumors, mainly hepatocellular carcinoma (HCC), arise from mature cell types has been challenged in recent dec-ades. The results of several studies suggest that HCC can be derived from liver stem cells. There are four levels of cells in the liver stem cell lineage: hepatocytes, hepatic stem cells/oval cells, bone marrow stem cells and hepato-pancreas stem cells. However, whether HCC is resulted from the differentiation block of stem cells and, moreover, which liver stem cell lineage is the source cell of hepatocarcinogenesis remain controversial. In this review, we focus on the current status of liver stem cell research and their roles in carcinogenesis of HCC, in order to explore new approaches for stem cell therapy of HCC.

    Full Text Available Osseous metastasis in patients of thyroid carcinoma is not very common, and appendicular skeleton is very rare. Bone metastasis represents a complication, especially of follicular thyroid carcinoma and severely reduces the quality of life causing pain, and fractures. Diagnosis is typically done by correlating clinical suspicion with imaging. Occult clinical presentations usually delay the detection and management of patients with bone metastasis from thyroid carcinoma. There is limited information about the clinical presentations and prognosis of patients with follicular thyroid carcinoma with bone metastasis. We hereby present a case report of right arm swelling diagnosed as metastatic carcinoma having metastasis from thyroid primary.

  20. Solitary pulmonary metastases from renal cell carcinoma. Comparison of high-resolution CT with pathological findings

    International Nuclear Information System (INIS)

    The aim of this study was to examine the radiographic features of solitary pulmonary metastases from renal cell carcinoma by comparing high-resolution CT (HRCT) findings with histopathological observations. Three thoracic radiologists retrospectively reviewed HRCT findings from eight patients who underwent surgery on the basis of the diagnosis of solitary pulmonary metastatic renal cell carcinoma. The histopathological diagnoses for six of these eight lesions were metastases from clear cell carcinoma of the kidney, one case was a metastasis from papillary renal cell carcinoma, and the remaining case was a metastasis from a poorly differentiated carcinoma including predominantly spindle cells, papillary cells, and clear cells. The HRCT findings of all cases of clear cell carcinoma showed solid nodular lesions without ground-glass attenuation (GGA). The HRCT findings for one case of papillary renal cell carcinoma showed a lobulated nodule with a small amount of GGA in an area in the periphery and an air bronchogram. The HRCT findings of the remaining case of poorly differentiated carcinoma showed an ill-defined nodule with a GGA area and pleural indentations. In brief, solitary pulmonary metastases from renal cell carcinoma may present as a smoothly marginated nodule, lobulated nodule, or a nodule with peripheral GGA. (author)

    2014-09-01

    Full Text Available : Granulomatous inflammation is a distinctive pattern of chronic inflammatory reaction characterized by microscopic aggregation of activated macrophages which often develop epithelioid appearance and multinucleate giant cells. Granulomas are encountered in limited number of infectious and some non-infectious conditions. Granulomas have been described within the stroma of malignancies like carcinomas of the breast and colon, seminoma and Hodgkin’s lymphoma, where they represent T-cell-mediated reaction of the tumor stroma to antigens expressed by the tumor. Granulomatous reaction in association with renal cell carcinoma (RCC is uncommon, with only few published reports in the literature. We describe a case of conventional (clear cell RCC associated with epithelioid cell granulomas within the tumor parenchyma.

    Full Text Available Abstract Background Metastases from hepatocellular carcinoma (HCC can be found in the lung and adrenal gland. We report case of a patient who presented with adrenal metastasis as the first clinical manifestation of HCC. Case presentation A patient was referred for surgical treatment for a tumor in retro-peritoneal space. The computerized tomography (CT scan revealed a mass originating from the left adrenal gland. The patient underwent left adrenalectomy and the exploration of abdominal cavity did not reveal any other palpable lesions. Histologically, the resected lesion was a poorly differentiated metastatic tumor from HCC. Seven months later patient was readmitted complaining of cachexia, icterus, and significant weight loss. CT scan revealed hyperdense lesions of the liver Conclusion HCC may have atypical presentations like in present case. Fine needle aspiration/tru-cut® biopsy might be useful in the investigation of an accidentally discovered adrenal mass regardless of the size and can lead to the detection of a primary tumor.

  3. CT differentiation of renal tumor invading parenchyma and pelvis: renal cell carcinoma vs transitional cell carcinoma

    International Nuclear Information System (INIS)

    The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

    Full Text Available Abstract Background Renal cell carcinoma can cause various paraneoplastic syndromes including metabolic and hematologic disturbances. Paraneoplastic hypereosinophilia has been reported in a variety of hematologic and solid tumors. We present the first case in the literature of severe paraneoplastic hypereosinophilia in a patient with renal cell carcinoma. Case presentation A 46 year-old patient patient with a history of significant weight loss, reduced general state of health and coughing underwent radical nephrectomy for metastasized renal cell carcinoma. Three weeks after surgery, the patient presented with excessive peripheral hypereosinophilia leading to profound neurological symptoms due to cerebral microinfarction. Systemic treatment with prednisolone, hydroxyurea, vincristine, cytarabine, temsirolimus and sunitinib led to reduction of peripheral eosinophils but could not prevent rapid disease progression of the patient. At time of severe leukocytosis, a considerable increase of cytokines associated with hypereosinophilia was measurable. Conclusions Paraneoplastic hypereosinophilia in patients with renal cell carcinoma might indicate poor prognosis and rapid disease progression. Myelosuppressive therapy is required in symptomatic patients.

  6. Local thermal ablation of renal cell carcinoma

    International Nuclear Information System (INIS)

    Purpose: With evolving local thermal ablation technology, the clinical application of thermal ablation has been actively investigated in the treatment for renal cell carcinoma. We review the evolution and current status of radiofrequency ablation and microwave ablation for renal cell carcinoma. Materials and methods: All articles published in English on radiofrequency ablation or microwave ablation as a treatment for renal cell carcinoma were identified with a MEDLINE® and PubMed® search from 1990 to 2010. Results: Local thermal ablation has several advantages, including keeping more normal renal units, relatively simple operation, easy tolerance, fewer complications, a shorter hospitalization and convalescence period. Long-term data has determined radiofrequency ablation is responsible for poor surgical candidates with renal cell carcinoma, however, tumor size, location and shape might affect the efficacy of radiofrequency ablation. Microwave ablation can induce large ablation volumes and yield good local tumor control. Associated complications appear to be low. Conclusions: Local ablative approaches seem to represent an attractive alternative to extirpative surgery for the treatment of small renal neoplasms in select patients. Potential developments include concepts to improve the accuracy and effectiveness of thermal ablation by improving the guiding, monitoring capabilities and detection capacity of multi-center lesions to provide at least equivalent cancer control to conventional surgery.

    Full Text Available Circulating tumor cells (CTCs are those cells present in the blood and have antigenic and/or genetic characteristics of a specific tumor type. CTCs can be detected in the peripheral blood of cancer patients. Various techniques are available for detection of CTCs, which provide evidence for future metastasis. CTCs may provide new insight into the biology of cancer and process of metastasis in oral squamous cell carcinoma (OSCC. The detection of CTCs may represent a new diagnostic tool for predicting the occurrence of metastatic disease in OSCC and endow with the treatment strategies to efficiently treat and prevent cancer metastasis. This review gives an insight into the significance of CTCs and different techniques for detection of CTCs.

    About one-third of patients with advanced renal cell carcinoma (RCC) have bone metastasis that are often osteolytic and cause substantial morbidity, such as pain, pathologic fracture, spinal cord compression and hypercalcemia. The presence of bone metastasis in RCC is also associated with poor prognosis. Bone-targeted treatment using bisphosphonate and denosumab can reduce skeletal complications in RCC, but does not cure the disease or improve survival. Elucidating the molecular mechanisms of tumor-induced changes in the bone microenvironment is needed to develop effective treatment. The “vicious cycle” hypothesis has been used to describe how tumor cells interact with the bone microenvironment to drive bone destruction and tumor growth. Tumor cells secrete factors like parathyroid hormone-related peptide, transforming growth factor-β and vascular endothelial growth factor, which stimulate osteoblasts and increase the production of the receptor activator of nuclear factor κB ligand (RANKL). In turn, the overexpression of RANKL leads to increased osteoclast formation, activation and survival, thereby enhancing bone resorption. This review presents a general survey on bone metastasis in RCC by natural history, interaction among the immune system, bone and tumor, molecular mechanisms, bone turnover markers, therapies and healthcare burden.

  14. Osteoblastic bone metastases from renal cell carcinoma

    International Nuclear Information System (INIS)

    RCC accounts for only 2–3% of all cancers. Due to its’ non-specific symptoms disease is often diagnosed in advanced stage. Disseminated RCC frequently produces bone metastases that are almost always highly destructive, hyper vascularized and purely osteolytic. In this article we describe a case of a 71-year old male patient with disseminated osteoblastic bone metastases from renal cell carcinoma (RCC), and present a short review of published literature reporting cases of osteoblastic bone metastases from RCC. Our patient presented with thoracic pain aggravated by movement. He was diagnosed with predominantly osteoblastic bone metastases in the skeleton of thoracic and lumbar vertebra along with metastases in iliac bones, ribs, humerus and clavicles. Initially, origin of bone metastases was unknown, but later a small tumor in patient’s right kidney was identified. Microscopic evaluation of the open bone biopsy showed clear cell RCC with sarcomatoid differentiation. Although, due to its’ rarity, RCC is not included in the primary differential diagnosis in patients with osteoblastic metastases, such rare cases suggest that RCC may be considered in the diagnosis when there no other primary tumor is found

    Primary squamous cell colorectal carcinomas are uncommon, and their characteristics are not well known. They seem to occur most commonly in the fifth decade of life with a slight predominance for men. The most commonly reported anatomic locations are the rectum and the proximal colon. Clinical features and common diagnostic methods do not easily differentiate squamous cell colorectal carcinomas from adenocarcinomas. Because of their extremely rare occurrence, it is difficult to study their natural course, clinical behavior, and response to therapy. This report presents the case of a pure squamous cell colorectal cancer and provides a brief review of the literature, which includes 60 previously published cases. The case of a patient with T3N2M0 primary squamous cell carcinoma of the rectosigmoid colon, which was initially treated with abdominoperineal resection followed by adjuvant chemotherapy and radiation, is presented. During the follow-up, an elevated squamous cell carcinoma antigen (SCC Ag) level led to restaging computed tomography scans, which confirmed recurrent metastatic disease in the liver. Response to chemotherapy with a decrease in tumor size correlated with a decrease in the serum SCC Ag level. Although SCC Ag has been used as a tumor marker for squamous cell cancers of the lung, head and neck, uterine cervix, and esophagus, this is the first reported case of a squamous cell colon carcinoma presenting with an elevated SCC Ag at the time of recurrence. In addition, this patient showed an objective partial response to combination chemotherapy, with a decrease in the serum level of this tumor marker. PMID:12445380

    Full Text Available Pelvic squamous cell carcinoma of unknown primary origin has been described in several case reports of female patients. However, there have been no published reports describing male patients with pelvic squamous cell cancer of unknown primary origin. Our case describes a 52-year-old man who presented with right buttock pain, rectal urgency, and constipation. His physical examination demonstrated tenderness to palpation around his gluteal folds. Computed tomography scan of his abdomen and pelvis demonstrated a large mass in his retroperitoneum. The mass was determined to be squamous cell carcinoma of unknown primary origin. Additionally, the patient had small nodules in his right lower lung lobe and right hepatic lobe. The patient was treated with concomitant chemoradiation, including cisplatin and intensity-modulated radiation therapy, followed by carboplatin and paclitaxel. The patient achieved partial remission, in which he remained one year after his presentation. Our case is consistent with the literature which suggests that squamous cell carcinoma of unknown primary origin occurring outside of the head and neck region may have a more favorable prognosis than other carcinomas of unknown primary origin. Further studies are necessary to determine the most appropriate work-up, diagnosis, and optimal treatment strategies.

    Pelvic squamous cell carcinoma of unknown primary origin has been described in several case reports of female patients. However, there have been no published reports describing male patients with pelvic squamous cell cancer of unknown primary origin. Our case describes a 52-year-old man who presented with right buttock pain, rectal urgency, and constipation. His physical examination demonstrated tenderness to palpation around his gluteal folds. Computed tomography scan of his abdomen and pelvis demonstrated a large mass in his retroperitoneum. The mass was determined to be squamous cell carcinoma of unknown primary origin. Additionally, the patient had small nodules in his right lower lung lobe and right hepatic lobe. The patient was treated with concomitant chemoradiation, including cisplatin and intensity-modulated radiation therapy, followed by carboplatin and paclitaxel. The patient achieved partial remission, in which he remained one year after his presentation. Our case is consistent with the literature which suggests that squamous cell carcinoma of unknown primary origin occurring outside of the head and neck region may have a more favorable prognosis than other carcinomas of unknown primary origin. Further studies are necessary to determine the most appropriate work-up, diagnosis, and optimal treatment strategies. PMID:25478265

  18. Clear cell carcinoma of the endometrium: an uncommon entity with a favorable prognosis

    International Nuclear Information System (INIS)

    From 1969 to 1978, 345 patients with endometrial carcinoma were treated at the Medical College of Virginia. Twenty-three of these were clear cell carcinoma (6.6%). Previous reports indicate a poor prognosis with this histological entity. In this series no differences were noticed between clear cell carcinoma and classical adenocarcinoma with regard to variables such as age, race, stage at presentation or response to treatment. Clear cell carcinoma is a distinct histological entity and does not appear to be different than classical adenocarcinoma in its behavior and response to therapy. It is recommended that these tumors be managed by a combination of surgery and radiotherapy

    2012-02-01

    Clear-cell papillary renal-cell carcinoma (CCPC) and acquired cystic kidney disease-associated carcinoma (ACDAC) are neoplasms with distinct morphological characteristics that behave less aggressively than conventional renal-cell carcinomas. End-stage kidney specimens from 61 patients (47 males and 14 females) with 109 renal-cell carcinomas were selected. Papillary renal-cell carcinoma was the most common malignancy (61/109, 56%), followed by CCPC (20/109, 18%). The CCPC showed a papillary or tubular/solid architecture, clear cytoplasm, low nuclear grade, and a distinct immunohistochemical profile (RCC-, vimentin+, CK7+, p504S-). ACDAC displayed a variety of architectural patterns, eosinophilic cytoplasm, high nuclear grade, intratumoral calcium oxalate deposits, and an immunohistochemical profile similar to type 2 papillary renal-cell carcinoma (RCC+, vimentin+, CK7-/+, p504S+). Less than 5% (3/69) of pathologically staged renal-cell carcinomas in end-stage kidneys presented with lymphogenous and/or hematogenous metastases. PMID:21791489

    Full Text Available Malignant mixed germ cell tumour of the ovary containing embryonal carcinoma and choriocarcinoma is a very rare entity. These tumours can present as precocious puberty or menstrual irregularities in adolescent girls. Here we report a case of 22 year old lady who presented as 5 months pregnancy in antenatal clinic. MRI Imaging and tumour markers revealed malignant ovarian tumour. Patient underwent surgicopathological staging and was found to have malignant mixed germ cell tumour stage IIIB, comprising of both choriocarcinoma and embryonal carcinoma components. Patient received one cycle of chemotherapy and was called for follow up. Mixed malignant germ cell tumour of the ovary is a highly aggressive neoplasm that can present in advanced stage. A high clinical suspicion is needed in patients presenting with pelvic mass associated with menstrual irregularity or amenorrhoea in adolescent and young women.

    2013-01-01

    T lymphocytes can mediate the destruction of cancer cells by virtue of their ability to recognize tumor-derived antigenic peptides that are presented on the cell surface in complex with HLA molecules and expand. Thus, the presence of clonally expanded T cells within neoplastic lesions is an...... indication of ongoing HLA-restricted T cell-mediated immune responses. Multiple tumors, including renal cell carcinomas (RCCs), are often infiltrated by significant amounts of T cells, the so-called tumor-infiltrating lymphocytes (TILs). In the present study, we analyzed RCC lesions (n = 13) for the presence...... of expanded T-cell clonotypes using T-cell receptor clonotype mapping. Surprisingly, we found that RCCs comprise relatively low numbers of distinct expanded T-cell clonotypes as compared with melanoma lesions. The numbers of different T-cell clonotypes detected among RCC-infiltrating lymphocytes were...

  12. The Expression of p53 and Cox-2 in Basal Cell Carcinoma, Squamous Cell Carcinoma and Actinic Keratosis Cases

    Ülker KARAGECE YALÇIN

    2012-05-01

    Full Text Available Objective: The aim of this study was to investigate p53 and COX-2 expressions in basal cell carcinoma, squamous cell carcinoma and actinic keratoses, and to determine a possible relationship.Material and Method: 50 basal cell carcinoma, 45 squamous cell carcinoma and 45 actinic keratosis cases were evaluated. The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Full Text Available Introduction. Tattoos have increasingly become accepted by mainstream Western society. As a result, the incidence of tattoo-associated dermatoses is on the rise. The presence of a poorly differentiated squamous cell carcinoma in an old tattooed skin is of interest as it has not been previously documented. Case Presentation. A 79-year-old white homeless man of European descent presented to the dermatology clinic with a painless raised nodule on his left forearm arising in a tattooed area. A biopsy of the lesion revealed a poorly differentiated squamous cell carcinoma infiltrating into a tattoo. The lesion was completely excised and the patient remains disease-free one year later. Conclusion. All previous reports of squamous cell carcinomas arising in tattoos have been well-differentiated low-grade type or keratoacanthoma-type and are considered to be coincidental rather than related to any carcinogenic effect of the tattoo pigments. Tattoo-associated poorly differentiated invasive carcinoma appears to be extremely rare.

    Full Text Available Mixed adenoneuroendocrine carcinomas, spindle cell carcinomas, and clear cell carcinomas are all rare tumors in the biliary tract. We present the first case, to our knowledge, of an extrahepatic bile duct carcinoma composed of all three types. A 65-year-old man with prior cholecystectomy presented with painless jaundice, vomiting, and weight loss. CA19-9 and alpha-fetoprotein (AFP were elevated. Cholangioscopy revealed a friable mass extending from the middle of the common bile duct to the common hepatic duct. A bile duct excision was performed. Gross examination revealed a 3.6 cm intraluminal polypoid tumor. Microscopically, the tumor had foci of conventional adenocarcinoma (CK7-positive and CA19-9-postive surrounded by malignant-appearing spindle cells that were positive for cytokeratins and vimentin. Additionally, there were separate areas of large cell neuroendocrine carcinoma (LCNEC. Foci of clear cell carcinoma merged into both the LCNEC and the adenocarcinoma. Tumor invaded through the bile duct wall with extensive perineural and vascular invasion. Circumferential margins were positive. The patient’s poor performance status precluded adjuvant therapy and he died with recurrent and metastatic disease 5 months after surgery. This is consistent with the reported poor survival rates of biliary mixed adenoneuroendocrine carcinomas.

  5. Ethacrynic acid: a novel radiation enhancer in human carcinoma cells

    International Nuclear Information System (INIS)

    Purpose: Because agents that interfere with thiol metabolism and glutathione S-transferase (GST) functions have been shown to enhance antitumor effects of alkylating agents in vitro and in vivo, the present study was conceived on the basis that an inhibitor of GST would enhance the radiation response of some selected human carcinoma cells. Ethacrynic acid (EA) was chosen for the study because it is an effective inhibitor of GST and is a well known diuretic in humans. Methods and Materials: Experiments were carried out with well-established human tumor cells in culture growing in Eagle's minimum essential medium (MEM) supplemented with 10% fetal calf serum (FCS). Cell lines used were MCF-7, MCF-7 adriamycin resistant (AR) cells (breast carcinoma), HT-29 cells (colon carcinoma), DU-145 cells (prostate carcinoma), and U-373 cells (malignant glioma). Cell survival following the exposure of cells to drug alone, radiation alone, and a combined treatment was assayed by determining the colony-forming ability of single plated cells in culture to obtain dose-survival curves. The drug enhancement ratio was correlated with levels of GST. Results: The cytotoxicity of EA was most pronounced in MCF-7, U-373, and DU-145 cells compared to MCF-7 AR and HT-29 cells. The levels of GST activity were found to be lower in those EA-sensitive cells. A significant radiation enhancement was obtained with EA-sensitive cells exposed to nontoxic concentrations of the drug immediately before or after irradiation. The sensitizer enhancement ratio (SER) of MCF-7 cells was 1.55 with EA (20 μg/ml), while the SER of MCF-7 AR was less than 1.1. Based on five different human tumor cells, a clear inverse relationship was demonstrated between the magnitude of SER and GST levels of tumor cells prior to the combined treatment. Conclusion: The present results suggest that EA, which acts as both a reversible and irreversible inhibitor of GST activity, could significantly enhance the radiation response of

Recent review of the literature showed occasional cases with papillary or papillocystic growth patterns, ranging from 2 to 5 cm in diameter. We report a large 10 cm pancreatic tumor with papillocystic pathology features involving the pancreatic head. The growth pattern of these tumors could be mistaken for intraductal papillary mucinous tumors or other pancreatic cystic neoplasms.

    Full Text Available Tumor formation is a complex process that occurs in different steps and involves many cell types, including tumor cells, endothelial cells, and inflammatory cells, which interact to promote growth of the tumor mass and metastasization. Epigenetic alterations occurring in transformed cells result in de-regulation of miRNA expression (a class of small non-coding RNA that regulates multiple functions which contributes to tumorigenesis. The specific miRNAs, which have an aberrant expression in tumors, are defined as oncomiRNAs, and may be either over- or under-expressed, but down-regulation is most commonly observed.Renal cell carcinoma is a frequent form of urologic tumor, associated with an alteration of multiple signaling pathways. Many molecules involved in the progression of renal cell carcinomas, such as HIF, VEGF or mTOR, are possible targets of deregulated miRNAs. Within tumor mass, the cancer stem cell population is a fundamental component that promotes tumor growth. The cancer stem cell hypothesis postulates that cancer stem cells have the unique ability to self-renew and to maintain tumor growth and metastasis. Cancer stem cells present in renal cell carcinoma were shown to express the mesenchymal stem cell marker CD105 and to exhibit self-renewal and clonogenic properties, as well as the ability to generate serially transplantable tumors. The phenotype of cancer stem cell has been related to the potential to undergo the epithelial-mesenchymal transition, which has been linked to the expression pattern of tumorigenic miRNAs or down-regulation of anti-tumor miRNAs. In addition, the pattern of circulating miRNAs may allow discrimination between healthy and tumor patients. Therefore, a miRNA signature may be used as a tumor biomarker for cancer diagnosis, as well as to classify the risk of relapse and metastasis, and for a guide for therapy.

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    2016-04-01

    Soft tissue metastasis from any primary malignancy is considered very rare and a breast carcinoma metastasizing to soft tissue is still rarer. To the best of our knowledge, carcinoma breast with soft tissue metastasis to upper extremity is very uncommon with only six cases been reported in world literature till date and our case is the seventh such case in an 80-year-old female, previously treated for carcinoma right breast 15 years ago. The patient presented with progressive painful massive swelling of right upper arm measuring 21 cm × 17 cm, of 2 months duration. Histopathological examination of the swelling showed metastatic deposits from a poorly differentiated adenocarcinoma. Further immunohistochemical (IHC) analysis revealed tumor cells staining positive for estrogen and progesterone receptors while negative for HER 2-Nu, desmin, epithelial membrane antigen, CK7 and thyroid transcription factor-1 (TTF-1), suggestive of metastasis from a primary breast carcinoma. Only few case series and isolated cases reports have been published regarding any primary malignancy or breast carcinoma metastasizing to soft tissues. A thorough review of literature also reveals that our case is the largest soft tissue metastatic swelling from breast carcinoma ever reported. We hereby present this case with review of literature to highlight its extreme rarity, unusual presentation, clinicopathological characteristics and its overall prognosis. PMID:27121743

    Laryngeal spindle cell carcinoma (SpCC) is an uncommon subtype of squamous cell carcinoma which represents 0.5% of all laryngeal squamous cell carcinomas. It is a biphasic tumor consisting of the combination of a malignant mesenchymal spindle cell component and a squamous cell component that includes dysplasia, carcinoma in situ, or invasive carcinoma. Although it has aggressive biological features, the probability of making a diagnosis in the early stages is high as it often leads to obstructive symptoms in the early period. Due to its low incidence, there is no clear consensus on prognostic factors and optimal treatment strategies yet. In this paper, a 60-year-old laryngeal SpCC case that was effectively treated with wide local excision followed by adjuvant radiotherapy was presented with the literature. PMID:26788392

    Skin squamous cell carcinomas (SCCs) are arguably the second most common carcinoma of the skin and are responsible for the majority of non-melanoma skin cancer deaths. Gynecologist treated a Caucasian 56-years old female patient for genital wart with podophyllotoxin cream. She did not achieve complete response and therefore she has interrupted the therapy and the collaboration with the gynecologist. At the time of evaluation the lesion had a size of man's palm in anogenital region and showed characteristic features of neoplasm. The regional lymph nodes have produced infiltrated painful bubo. PCR analysis for HPV proved negative. Histopathology revealed well-differentiated squamous cell keratinizing carcinoma from the tumor as well as from the regional lymph node packet. Staging computed tomography scans proved negative and pelvis scans disclosed regional lymphadenopathy underlying the tumor. Palliative radiation therapy (by linear accelerator) was administered for the oversized tumor to the total TD 50.0Gy. The patient died 6 months after diagnostic assessment from cardio-respiratory failure. Staging computed tomography before her death did not disclose distinct metastases in her inner organs. Well-differentiated squamous cell keratinizing carcinoma could be growing endophytically affecting the underlying adipose tissue and musculature, with spreading into the regional lymph nodes. The rate of metastases into inner organs seems to vary according to the aggressiveness and metastatic behavior of each SCC. The case report calls for attention to the importance of collaboration among various specialists assisting in the diagnosis and management of skin neoplasm (Fig. 5, Ref. 12).

    2010-08-01

    Full Text Available PURPOSE: The determination of prognosis in patients with renal cell carcinoma (RCC is based, classically, on stage and histopathological aspects. The metastatic disease develops in one third of patients after surgery, even in localized tumors. There are few options for treating those patients, and even the new target designed drugs have shown low rates of success in controlling disease progression. Few studies used high throughput genomic analysis in renal cell carcinoma for determination of prognosis. This study is focused on the identification of gene expression signatures in tissues of low-risk, high-risk and metastatic RCC clear cell type (RCC-CCT. MATERIALS AND METHODS: We analyzed the expression of approximately 55,000 distinct transcripts using the Whole Genome microarray platform hybridized with RNA extracted from 19 patients submitted to surgery to treat RCC-CCT with different clinical outcomes. They were divided into three groups (1 low risk, characterized by pT1, Fuhrman grade 1 or 2, no microvascular invasion RCC; (2 high risk, pT2-3, Fuhrman grade 3 or 4 with, necrosis and microvascular invasion present and (3 metastatic RCC-CCT. Normal renal tissue was used as control. RESULTS: After comparison of differentially expressed genes among low-risk, high-risk and metastatic groups, we identified a group of common genes characterizing metastatic disease. Among them Interleukin-8 and Heat shock protein 70 were over-expressed in metastasis and validated by real-time polymerase chain reaction. CONCLUSION: These findings can be used as a starting point to generate molecular markers of RCC-CCT as well as a target for the development of innovative therapies.

    2010-09-01

    Uterine clear cell carcinoma (UCC) and uterine papillary serous carcinoma (UPSC) are rare entities that differ in clinical behavior from endometrial adenocarcinoma. Compared with endometrioid adenocarcinoma, they more often metastasize early and more commonly in the upper abdomen including the omentum. Treatment programs of UCC and UPSC at different stages vary and range from no adjuvant therapy in stage Ia to a wide variety of chemotherapies and radiotherapies in more advanced stages. This study presents the outcome of 109 patients with UCC or UPSC treated according to essentially the same treatment program from May 1993 to December 2004. Most patients were treated with a simple hysterectomy with no further adjuvant treatment. In stage Ia, 2/46 patients died of their disease and amongst all the stages, 30/109 patients died of their disease. These survival outcomes are comparable to or better than those presented previously. PMID:20944161

    Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancy. 25% to 57% of RCC patients exhibit overt evidence of metastatic disease at initial presentation. Metastases to the gallbladder is uncommon and usually detected in only 0.4-0.6% of autopsies. We report the case of a 58 year old man who presented with a metastasis in the gallbladder from RCC. He had undergone went a right nephrectomy four years ago. There was no evidence of metastasis. A follow up abdomen CT scan taken three years after operation showed a polypoid lesion within the gallbladder. The size of the polypoid lesion had increased at the follow up CT and the enhancement pattern of lesion became similar to that of RCC. A Cholecystectomy was performed. Histopathological examination revealed the polyp was clear cell carcinoma of metastatic origin from kidney.

  11. Acinic cell carcinoma of the parotid in children

    International Nuclear Information System (INIS)

    The imaging findings of two children with acinic cell carcinoma of the parotid gland are presented. Ultrasonic and computed tomography features are emphasized. One of these children, a 6 year old boy, suffers from the oculocerebrorenal syndrome of Lowe, a rare congenital, inherited condition manifested by defects of the nervous system (mental retardation, hypotonia), eyes (cataracts, glaucoma) and kidneys. To date, no known association exists between these two rare entities. The other child, a 10 year old girl, was otherwise well. The ultrasound findings of both cases demonstrate features more classic for a benign intraparotid mass than for a potentially malignant lesion. The possibility of acinic cell carcinoma should be considered if a well-defined, relatively homogeneously hypo-echoic intraparotid mass is encountered in a child, especially if cystic spaces are present. It was estimated that computed tomography findings reflected features already demonstrated by ultrasound and added little to characterization of the primary mass in this case. 12 refs.,5 figs

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    International Nuclear Information System (INIS)

    Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.)

The presence of 90-100% clear cells is rare. In the present case, a 35-year-old female patient presented with fever and a large abdominal mass in the right hypochondrium. Histology of the tumor revealed >95% clear cells and after taking multiple sections from different areas of tumor only few scattered cells with eosinophilic cytoplasm were found. Immunohistochemistry with Hep Par 1, Glypican 3 and polyclonal carcinoembryonic antigen were negative as were all other markers for metastatic clear cell tumors. Histological diagnosis was based on routine H and E sections showing a histological pattern of architecture with thickened trabeculae. We describe a rare case of CCHCC with >95% clear cells and no immunoreactivity in tumor cells in a non-cirrhotic liver.

The histopathological study confirmed the clinical suspicion of squamous cell carcinoma. Cutaneous neoplasia arising from the vitiliginous skin is a rare situation. Lack of melanin leaves the skin vulnerable to ultraviolet radiation damage, which may predispose to cutaneous neoplasia. Therefore, the importance of photoprotection has been stressed upon through this illustration.

    Bukowski, Ronald M; Heng, Daniel Y.C.

    2011-01-01

    The treatment of metastatic renal cell carcinoma (RCC) has changed dramatically with the introduction of targeted therapies including sunitinib, sorafenib, and temsirolimus. Because patients with conventional clear cell histology account for 75- 80% of all patients with RCC, there has been little accumulated evidence on the treatment of patients with non-clear cell histologies. Most clinical trials have excluded them from enrolment, except for randomized studies investigating temsirolimus. Ma...

    Full Text Available Para avaliar fatores relacionados ao seguimento oncológico dos carcinomas basocelulares da face, foi realizada a análise de série de casos. Avaliaram-se 465 pacientes, com 834 carcinomas basocelulares de face; 3,1% apresentaram recidivas. Nos tumores incompletamente excisados, a recidiva foi 14,7% contra 2,3% dos tumores, com margens livres. Ocorreram mais na região nasal. As taxas de recorrência evidenciaram risco cumulativo. Estes achados reforçam a importância do seguimento oncológico após a cirurgia do carcinoma basocelular.To evaluate factors related to oncological follow-up of basal cell face carcinomas it was carried out the analysis of a series of cases. Four hundred sixty-five patients with 834 basal cell face carcinomas were evaluated; 3,1% presented recurrences. There was 14.7% of recurrence in incompletely excised tumors against 2.3% of the tumors with clear margins. Recurrences were more prevalent on the nose. Relapse rates showed a cumulative risk. These findings reinforce the importance of oncological follow-up after surgery of basal cell carcinoma.

  12. All delays before radiotherapy risk progression of Merkel cell carcinoma

    International Nuclear Information System (INIS)

    Prolonged waiting times for radiotherapy have resulted in many centres assigning priorities to various patient or diagnostic groups. A high risk of progression on a waiting list is one factor that would reasonably influence the priority. The present descriptive study of 27 patients with Merkel cell carcinoma (MCC) found that a median wait of 24 days for radiotherapy is associated with a high risk of progression. Eleven (41%) of 27 patients developed progressive disease, including five (45%) of 11 patients waiting for adjuvant radiotherapy. Patients treated adjuvantly also had longer waiting times prior to their initial radiotherapy consultation (median 41 days), which may have contributed to the rate of progression. Merkel cell carcinoma is an aggressive but curable malignancy and appropriate management should include efforts to minimize all potential delays prior to the commencement of radiotherapy.

    2015-10-01

    Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

    Full Text Available The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS, is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the odontogenic keratocysts are usually one of the first manifestations of the syndrome. This case report presents a patient diagnosed as NBCCS by clinical, radiographic and histological findings in a 13-year-old boy. This paper highlights the importance of early diagnosis of NBCCS which can help in preventive multidisciplinary approach to provide a better prognosis for the patient.

    2015-12-01

    Cellular cannibalism has been defined as a large cell engulfing a slightly smaller one within its cytoplasm. It has been described in various cancers like bladder cancer, breast cancer, lung cancer, gastric cancer, oral squamous cell carcinoma. Cellular cannibalism has been well correlated with anaplasia, tumor aggressiveness, grading and metastatic potential. Present review focuses on significance of cannibalism in relation to cancer with special emphasis on oral squamous cell carcinoma. PMID:26710834

  1. Do Clear Cell Papillary Renal Cell Carcinomas Have Malignant Potential?

    Science.gov (United States)

    Diolombi, Mairo L; Cheng, Liang; Argani, Pedram; Epstein, Jonathan I

    2015-12-01

    There have been no recurrences or metastases of clear cell papillary renal cell carcinoma (CCPRCC) in 268 reported cases with follow-up in the English-language literature. We identified all our cases of CCPRCC (1990 to 2013), reviewing all cases that preceded the formal designation of the entity. Immunohistochemical stains were performed on 32 cases during their initial workup. In addition, stains for carbonic anhydrase IX and cytokeratin 7 were performed on 2 cases, one with atypical follow-up and the other with a more compact morphology, although not performed initially. An extended panel with AMACR, CD10, and renal cell carcinoma (RCC) was added to the case with atypical follow-up. Fluorescence in situ hybridization for chromosomes 3p, 7, and 17 was performed on the latter case and on another clinically presumed metastatic tumor. In classic cases, immunohistochemical staining was not performed. Fifty-eight patients (31 women; 27 men) with follow-up data were included in our study; 39 cases were from our consult service. The patients' ages ranged from 36 to 83 years. Thirty-five patients had cystic or partially cystic lesions; 6 tumors were multifocal, 3 of which were bilateral. The majority (53 patients; 91.4%) presented with stage pT1 disease (size range, 0.2 to 8 cm), 2 patients presented with pT2 disease (8.5 and 10.3 cm), 1 patient presented with pT3 disease (6.5 cm sarcomatoid RCC focally extending out of the kidney), and pathologic stage was unavailable in 2 cases. Treatment consisted of 29 partial nephrectomies, 26 radical nephrectomies, 2 cryoablations, and 1 cyst ablation. The resection margins were negative in all but one case, with this case disease free after a 26-month period. Two patients had intraoperative tumor disruption and were disease free at 9 and 34 months. Five patients had synchronous ipsilateral renal cell carcinomas (non-CCPRCC). Mean follow-up time was 21 months (range, 1 to 175 mo), with all but 3 patients having no evidence of

    2016-04-01

    Full Text Available A multifocal biphasic squamoid alveolar renal cell carcinoma in a 68-year-old man is reported. Four different peripheral tumor nodules were identified on gross examination. A fifth central tumor corresponded to a conventional clear cell renal cell carcinoma. Biphasic squamoid alveolar renal cell carcinoma is a rare tumor that has been very recently characterized as a distinct histotype within the spectrum of papillary renal cell carcinoma. Immunostaining with cyclin D1 seems to be specific of this tumor subtype. This is the first reported case with multifocal presentation.

  5. Nonsurgical Treatment Options for Basal Cell Carcinoma

    Directory of Open Access Journals (Sweden)

    Mary H. Lien

    2011-01-01

    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

  6. Percutaneous Cryoablation for Renal Cell Carcinoma

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Renal cell carcinoma (RCC is the most common type of kidney cancer in adults. Nephron sparing resection (partial nephrectomy has been the “gold standard” for the treatment of resectable disease. With the widespread use of cross sectional imaging techniques, more cases of renal cell cancers are detected at an early stage, i.e. stage 1A or 1B.  This has provided an impetus for expanding the nephron sparing options and especially, percutaneous ablative techniques.  Percutaneous ablation for RCC is now performed as a standard therapeutic nephron-sparing option in patients who are poor candidates for resection or when there is a need to preserve renal function due to comorbid conditions, multiple renal cell carcinomas, and/or heritable renal cancer syndromes. During the last few years, percutaneous cryoablation has been gaining acceptance as a curative treatment option for small renal cancers. Clinical studies to date indicate that cryoablation is a safe and effective therapeutic method with acceptable short and long term outcomes and with a low risk, in the appropriate setting.  In addition it seems to offer some advantages over radio frequency ablation (RFA and other thermal ablation techniques for renal masses.

  7. CT findings of signet ring cell carcinoma of the stomach

    International Nuclear Information System (INIS)

    Signet-ring cell carcinoma is rather invasive and infiltrative than other histologic types of gastric cancer. We evaluated the characteristic CT findings of signet-ring cell carcinoma especially in the intensity and pattern of contrast enhancement. We analyzed the CT findings of 22 cases with histologically proven signet-ring cell carcinoma, and compared them with those of 35 cases with histologically proven tubular adenocarcinoma. The double ring enhancement of the gastric mass was seen in 12 cases of signet-ring cell carcinoma and only one case of tubular adenocarcinoma. The masses of signet-ring cell carcinoma were enhanced more by the CT number of 10.2 than those of tubular adenocarcinoma. Of the masses of signet-ring cell carcinoma, those showed double ring enhancement were more intensely enhanced than those showed diffuse enhancement by the CT number of 22.9. We thought that neovascularity and different infiltration of the tumor cells in the gastric wall were responsible for the intense enhancement and double ring sign of signet-ring cell carcinoma. The possibility of signet-ring cell carcinoma is high if a gastric mass show double ring sign and strong contrast enhancement

    2014-01-01

    Full Text Available Context Squamous carcinoma of the ampulla of Vater is a very rare tumor with only three cases been reported so far. Case report Here, we report the case of a 68-year-old man who presented with painless obstructive jaundice, general fatigue, loss of appetite and weight loss. Laboratory tests revealed hypochromic anemia. Total and direct bilirubin, alkaline phosphatase, liver enzymes, carbohydrate antigen 19-9 (CA 19-9 and carcinoembryonic antigen (CEA were all elevated. Abdominal ultrasonography and computed tomography showed a distended gallbladder, dilatation of the intra- and extra-hepatic bile ducts and enlargement of the pancreatic head. Endoscopic retrograde cholangiopancreatography revealed a bulging papilla with infiltrative growth at the ampulla of Vater but endoscopic biopsies were inconclusive. The patient was treated with classical Whipple’s pancreaticoduodenectomy. Histopathological examination showed a moderately differentiated squamous cell carcinoma. Multiple serial sectioning of the tumor specimen failed to detect an adenomatous component. Regional lymph nodes and resection margins were free of tumor and the disease was classified as stage IIA (T3N0M0 according to the TNM system. Adjuvant treatment was not given. Despite curative resection, multiple liver metastases developed after four months and the patient succumbed to progressive hepatic failure 5 months after the operation. Conclusion Primary pure squamous cell carcinoma of the ampulla of Vater is a very rare histological type of carcinoma. Clinical characteristics and optimal treatment are obscure. Primary surgical treatment with curative intent should be performed although this type of carcinoma associates with dismal prognosis.

    Langerhans cells (LCs) may be involved in the immunosurveillance against tumors as antigen-presenting cells. Our objective has been to determine the relevance of LC in progression of larynx squamous cell carcinomas and their relationship with different subpopulations of tumor-infiltrating cells. LCs were investigated by immunohistochemical methods using anti-CD1 antibody. LCs were detected in most of the primary tumors studied (44 out of 50) and also in metastases (6 out of 10) and recurrences (2 out of 3), but we did not find any statistical association between number of LCs and clinical-pathological parameters or survival. However, the number of LCs was increased in patients with evident infiltration of lymphocytes, mainly cytotoxic T cells. We can conclude that although LCs did not show clinical utility as prognostic marker, they may play a role in releasing an active immune response in larynx carcinomas, according to their ability to present antigens to sensitized T cells.

    Full Text Available Sarcomatoid Carcinoma (SC is an unusual and aggressive variant of squamous cell carcinoma, which frequently recurs and metastasizes; for this reason, the right diagnosis is very important. It is considered to be a biphasic tumor made up of cells from squamous and spindle cells carcinoma with a sarcomatous aspect, but of epithelial origin. The diagnosis often represents a clinical-pathological challenge where the study with immunohistochemical technique (IHC is key to the histopathological diagnosis. The reported cases related to oral mucosa are limited. In this work we present two SC cases where the use of IHC allowed us to achieve a conclusive diagnosis.

  20. Review of photodynamic therapy with 5-methyl aminolevulinate in actinic keratosis, epidermoid carcinoma and basal cell carcinoma

    International Nuclear Information System (INIS)

    A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities

  2. 11C-Acetate PET imaging for renal cell carcinoma

    International Nuclear Information System (INIS)

    In this study, we investigated the effectiveness of positron emission tomography (PET) with 11C-acetate (AC) for evaluation of renal cell carcinoma. Enrolled in the study were 20 patients with suspected renal tumour, one of whom had three renal lesions. In all, 22 renal lesions were evaluated. Following administration of 350 MBq (10 mCi) of AC, whole-body PET images were obtained. Based on these PET findings, kidney lesions were scored as positive or negative. The PET results were correlated with the CT findings and histological diagnosis after surgery. In 18 patients, 20 tumours were diagnosed as renal cell carcinoma. Lesions in the remaining two patients were diagnosed as complicated cyst without malignant tissue. Of the 20 renal cell carcinomas. 14 (70%) showed positive AC PET findings; 6 were negative. The two patients with complicated cyst had negative AC PET findings. Of the 20 renal cell carcinomas, 19 were clear-cell carcinoma and 1 was a papillary cell carcinoma. This papillary cell carcinoma showed high AC uptake. AC demonstrates marked uptake in renal cell carcinoma. These preliminary data show that AC is a possible PET tracer for detection of renal cancer.

    A 64-year-old male presented with lower back pain, radiating in a sciatic-type distribution, swelling in his lower abdomen and right leg, and edema of the scrotum and penile shaft. A sonogram and CT imaging indicated an enhancing mass in the right kidney and a spinal metastasis. The right lower extremity and penoscrotal lymphedema was caused by lymphatic obstruction due to a sacral metastasis of renal cell carcinoma. He was treated with cytoreductive nephrectomy, radiation and a systemic tyrosine kinase inhibitor. Pelvic imaging is suggested to determine whether malignant lymphatic obstruction is present when presented with idiopathic penoscrotal edema. PMID:26267035

    Full Text Available We report a case of synchronous bilateral adrenal metastasis of renal cell carcinoma. The contralateral metastatic adrenal mass was treated by the laparoscopic transperitoneal approach. The renal mass and its huge ipsilateral metastatic adrenal gland were removed en bloc with open procedure. A 54-year-old man presented to our clinic with left-sid renal cell carcinoma synchronously bilateral adrenal metastases. The primary tumor was localized in the upper-mid pole of the kidney. The diagnosis was established preoperatively by computed tomography. The size of the contralateral adrenal mass was 65 x 45 mm, but the ipsilateral metastatic adrenal mass was huge (140 x 65 mm. After all analysis and other scannings for any metastasis, a contralateral lapararoscopic transperitoneal adrenalectomy and a left open nephroadrenalectomy were performed simultaneously. Synchronous bilateral adrenal metastases from primary renal cell carcinoma without another metastasis is very rare. The optimal surgical procedure should be selected according to the metastatic adrenal masses size and the patient%u2019s status.

    Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC. PMID:27457076

    Full Text Available Reena Kabaria, Zachary Klaassen, Martha K Terris Department of Surgery, Section of Urology, Augusta University, Augusta, GA, USA Abstract: This review provides an overview of the incidence of renal cell carcinoma (RCC and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses. The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Patient: Female, 60 Final Diagnosis: Gastroesophageal carcinoma with rectal metastasis Symptoms: Bloating • constipation • weight loss Medication: — Clinical Procedure: Endoscopy • flexible sigmoidoscopy • lower endoscopic ultrasound Specialty: Gastroenterology and Hepatology Objective: Unusual clinical course Background: Gastroesophageal cancers, previously considered rare, are rapidly increasing worldwide. We present here a unique case of gastroesophageal carcinoma with metastasis to the rectum. Case Report: A 60-year-old female patient presented with constipation, bloating, and weight loss of 4-month duration. She had undergone sleeve gastrectomy 6 years before. Endoscopies performed revealed a friable-looking mucosa in the lower esophagus and a polypoid rectal mass. Histopathological examination from both the esophageal and rectal lesions revealed poorly differentiated adenocarcinoma cells. Immunohistochemistry stain from both specimens was positive for CK7 supporting the gastric site primary with metastasis to the rectum. Further evaluation also revealed metastasis to bone and malignant pleural effusion. Chemotherapy with palliative intent was initiated. Conclusions: Colorectal metastasis is commonly seen from cancers of the breast, stomach, melanoma, kidney, prostate, and ovaries. However, colorectal metastasis from gastroesophageal cancer has never been reported in the medical literature. Diagnosis relies on histopathologic examination and immunohistochemical staining of the tumor. Treatment depends on the tumor stage. Tumors with widespread metastatic disease are candidates for palliative chemotherapy. PMID:27558656

    Clear cell carcinoma, not otherwise specified (NOS)/hyalinising clear cell carcinoma (HCCC) is a rare entity in salivary gland tumour. The aim of the research is to review the current concepts and characteristics of this carcinoma. The clinical and pathological data of the disease obtained from literature and two original cases were analysed. Overall, 152 cases were reviewed up to the year 2014. The carcinomas were noted often in woman, in the seventh decade of life, located in oral cavity and as early-stages cancers. On pathological examination, they were characterized by tumour cells having clear cell morphology with hyalinised stroma. Immunohistochemical studies revealed that the carcinoma is positive for cytokeratin and negative for myoepithelial differentiation. EWSR1-ATF1 fusion is specific for the carcinoma. Also, 9% of the reported cases had local nodal metastasis, with 6 cases demonstrating distant metastases at presentation. On follow-up, 22% of patients had recurrent or with persistent diseases after surgery. The time for the first recurrence could be as long as 24 years. Risk factors for recurrence include advanced stage at diagnosis and metastases at presentation. To conclude, HCCC is a low grade malignancy but have the potential for local metastases, recurrence, distant metastases and cancer-related death. PMID:27150676

  11. CT staging of renal cell carcinoma

    International Nuclear Information System (INIS)

    Objective: To assess the usefulness of computerized tomography (CT) in the characterization of renal masses, in order to stage them, determine their prognosis and their appropriate clinical and/or surgical management. Material and Methods: Between 1988 and 2001, we selected 63 patients with renal tumors that had been examined by pathology. Patient's ages ranged from 16 to 88 years (25 women, 38 men). The studies were performed with a sequential helical CT, using 5 mm thickness sections every 5mm evaluating the cortico medullar and nephrographic phases. Renal tumors were characterized and staged without any knowledge about the pathological findings; subsequently the tomographic characteristics were compared to such findings. The following characteristics were evaluated: 1) mixed solid-cystic nature; 2) size; 3) borders; 4) enhancement; 5) necrosis; 6) hemorrhage; 7) central scar; 8) presence of fat; 9) collecting system; 10) capsular invasion; 11) perirenal fat invasion; 12) vessels; 13) Gerota's fascia; 14) lymph nodes; and 15) local and/or distant metastases. Results: Of the 63 tumors, 2 were complicated cysts; of the 61 remaining tumors, 10 were angiomyolipomas, 1 was a renal lymphoma, 1 was a focal xantogranulomatose pyelonephritis, 1 was a metanephric adenoma, 3 papillary renal cell carcinoma (RCC), 4 transitional cell tumors, 4 oncocytomas, 37 clear cell renal carcinoma. The CT could correctly characterize the 2 cystic tumors as such, as well as the 9 angiomyolipomas and the 4 transitional cell tumors. The 48 other tumors (1 angiomyolipoma, 1 lymphoma, 1 focal xantogranulomatose pyelonephritis, 1 metanephric adenoma, 3 papillary RCC, 4 oncocytomas, and 37 cell renal carcinomas) remaining were characterized as renal adenocarcinomas and CT staged. Conclusion: CT is a useful method to characterize renal masses since it determines their solid-cystic or fatty structure; aiding in many cases to define a surgical treatment. For the CT staging of renal tumors, the

    Background. The concomitant occurrence of a renal cell carcinoma and retroperitoneal sarcoma is extremely rare with only few cases being reported. Methods. We present a case of simultaneous renal cell carcinoma and exceptionally large size retroperitoneal sarcoma involving small intestine. Surgical resection of retroperitoneal sarcoma and simultaneous right nephrectomy were performed. Results. Patient developed recurrent and metastatic disease and underwent debulking surgery following by chemotherapy. Despite aggressive behavior of the retroperitoneal sarcomas, patient is currently (7 years after simultaneous resection and nephrectomy) recurrence-free. Conclusions. Complete surgical resection is the mainstay of therapy for both renal cell carcinoma and retroperitoneal sarcoma. We present a case of simultaneous renal cell carcinoma and exceptionally large size retroperitoneal sarcoma. Debulking surgery and chemotherapy were helpful in our case. PMID:27595033

    Full Text Available True metastases to prostate from solid tumors are reported only in 0.2% of all surgical prostatic specimens and 2.9% of all male postmortems. Clinical context, morphological features, and immunohistochemical localization of prostate specific antigen (PSA are supposed to clarify the differential diagnosis between a secondary and a primary tumor. We report an unusual and rare case of secondary signet ring cell carcinoma (SRCC of prostate in which the clinical data and signet ring cell morphology pointed toward the diagnosis of a primary SRCC. Immunohistochemistry (IHC for PSA not only proved the case to be a secondary SRCC but also initiated the process for diagnosis of the occult primary malignancy in the patient′s stomach.

    Full Text Available

    We present a case of a primary advanced gastric tumor that was composed of 2 different pathological components: small cell carcinoma and moderately-differentiated adenocarcinoma. The patient was still alive four years after the surgery was performed, without recurrence. A large part of the tumor consisted of a diffuse sheet of small cell carcinoma, which transitioned into another small portion consisting of moderately-differentiated tubular adenocarcinoma components. Therefore, this case raised the possibility that small cell gastric carcinoma may originate from totipotential stem cells of the stomach. Although small cell carcinoma progresses aggressively, and patients with it have an extremely poor prognosis, this patient recovered uneventfully after the surgical resection, and has remained in good health, without any recurrences.

    Full Text Available Adrenocortical carcinoma (ACC is a rare malignancy and cytodiagnosis of this tumor is not routinely encountered by a cytopathologist. Here, we report a case of ACC initially diagnosed by computed tomography (CT-guided fine needle aspiration cytology (FNAC with the help of immunocytochemistry. A 48-year-old lady presented with flank pain and abdominal mass for the last 6 months. A CT scan of her abdomen revealed a large mass arising from the upper part of the left kidney. CT-guided FNAC was performed. Cytologic smears showed pleomorphic large cells arranged discretely and in small aggregates against a myxoid background. The cells had a high nucleocytoplasmic ratio, anisonucleosis and conspicuous nucleoli. Based on cytomorphology, differential diagnoses of ACC and renal cell carcinoma (RCC were made. On immunocytochemistry, the tumor cells were synaptophysin, inhibin, vimentin and Melan-A positive but cytokeratin and epithelial membrane antigen negative. Thus, a cytodiagnosis of myxoid ACC was made and histopathologic examination was suggested. Subsequent histologic examination and immunohistochemistry proved the case to be myxoid ACC.

    Companion animals may serve as valuable models for studying human cancers. Although KRAS is the most commonly mutated gene in human ductal pancreatic cancers (57%), with mutations frequently occurring at codons 12, 13 and 61, human pancreatic acinar cell carcinomas (ACCs) lack activating KRAS mutations. In the present study, 32 pancreatic ACC samples obtained from 14 dogs and 18 cats, including seven metastases, were analyzed for six common activating KRAS mutations located in codons 12 (n = 5) and 13 (n = 1) using Sequenom MassARRAY. No KRAS mutations were found, suggesting that, similar to human pancreatic ACC, KRAS mutations do not play a critical role in feline or canine pancreatic ACC. Due to the similarity of the clinical disease in dogs and cats to that of man, this study confirms that companion animals offer potential as a suitable model for investigating this rare subtype of pancreatic carcinoma.

    2016-01-01

    Bruton’s tyrosine kinase (Btk) is a member of the Tec-family non-receptor tyrosine kinases family. It has previously been reported to be expressed in B cells and has an important role in B-cell malignancies. While the roles of Btk in the pathogenesis of certain B-cell malignancies are well established, the functions of Btk in gastric carcinoma have never been investigated. Herein, we found that Btk is over-expressed in gastric carcinoma tissues and gastric cancer cells. Knockdown of Btk expression selectively inhibits the growth of gastric cancer cells, but not that of the normal gastric mucosa epithelial cell, which express very little Btk. Inhibition of Btk by its inhibitor ibrutinib has an additive inhibitory effect on gastric cancer cell growth. Treatment of gastric cancer cells, but not immortalized breast epithelial cells with ibrutinib results in effective cell killing, accompanied by the attenuation of Btk signals. Ibrutinib also induces apoptosis in gastric carcinoma cells as well as is a chemo-sensitizer for docetaxel (DTX), a standard of care for gastric carcinoma patients. Finally, ibrutinib markedly reduces tumor growth and increases tumor cell apoptosis in the tumors formed in mice inoculated with the gastric carcinoma cells. Given these promising preclinical results for ibrutinib in gastric carcinoma, a strategy combining Btk inhibitor warrants attention in gastric cancer. PMID:27508020

  12. A contribution to radiotherapy of the larger-celled bronchial carcinoma

    International Nuclear Information System (INIS)

    This work consists of a retrospective definition of disease courses of 859 patients with lung tumors and the definition of the survival curves in their dependence on histology, radiation dose and sex. With 721 larger-celled bronchial carcinomas the ratio of men to women was 12:1. The age peak lay between 60 and 70 years. The one/five year survival rate of all included larger-celled bronchial carcinomas (n=701) was, independent from the therapy form, 35.7, resp. 4.78%. The one year/five year survival rates were for the squamous epithelia 31.08/0.58%, for the undifferentiated carcinomas 25.34/3.41%, and for the lung tumors without histology 35.4/5.14%. Lobectomized patients with squamous epithelium carcinoma had in comparison to pneumonectomized patients a clearly higher survival chance. A clearly sex-dependent predisposition for a certain type of carcinoma was not present. (TRV)

    Full Text Available The clinical and morphological picture of Merkel cell carcinoma (MCC may be rather challenging; therefore, the immunohistochemical profile plays a relevant role in confirming the microscopic diagnosis. A panel of antibodies including cytokeratins 20, 7 and epithelial membrane antigen, and neuronspecific enolase is used in confirming the morphological diagnosis of MCC. The majority of MCCs express CK20 and are CK7-negative. Herein, we present a case of primary cutaneous neuroendocrine carcinoma with an atypical immunohistochemical pattern. A 83-years old woman presented with a painless plaque, red to violaceous in colour, located in the leg. The skin tumor was excided, formalin-fixed and paraffinembedded. Tissue sections were immunostained with a panel of antibodies routinely utilized in complex primary skin tumors for evidencing epithelial and neuroendocrine differentiation of tumor cells. The neuroendocrine differentiation of tumor cells was evidenced by their immunoreactivity for synaptophysin, chromograninA and neuron-specific enolase. Tumor cells also showed diffuse cytoplasmic staining for CK7. No immunoreactivity was detected for CK20 and thyroid transcription factor-1. Our data, together with previous rare reports of CK20-/CK7+ MCCs, lay stress on the importance of routinely utilizing a panel of antibodies in the differential diagnosis of complex primary carcinomas of the skin and may have important implications in expanding the differential diagnosis of skin tumors. In particular, caution should be taken in excluding the diagnosis of MCC only on the basis of the absence of reactivity of tumor cells for CK20, favouring the wrong diagnosis of less aggressive skin tumors.

Of the few teratomas found in the head and neck, malignant transformation of a teratomatous element is very uncommon, and primary bone involvement within the head and neck is even rare. We present a case of primary malignant mixed germ cell Tumour involving the mandible, the present case presented malignant transformation of the epithelial component showing foci of squamous cell carcinoma within the GCT.

  15. Bronchiolo-alveolar cell carcinoma: A review of 11 cases

    International Nuclear Information System (INIS)

    Eleven patients with proved Bronchiolo-alveolar cell carcinoma were found in the chest department of the national menical center from 1975 to 1981. The clinical od Bronchiolo-alveolar cell carcinoma is recently increased as primary lung carcinoma. The results were as follow. 1. The ratio of male and female was 5 : 6, and an incidence of 4.4% among total primary lung cancer patients. The highest incidence (3 of cases) was seen in the sixth decade, and the remaining cases were evenly distributed in the third, fourth, and fifth decades of life. Among them youngest was 29 years old and the oldest was 66 years old. 2. Clinical and radiological initial diagnosis prior to the final diagnosis were as follows; pulmonary tuberculosis; 7 cases, pneumonia; 1 case, bronchiectasis; 1 case, and lung cancer; 2 cases. 3. Radiological examination of chest presented several pictures; most commonly, homogenous or patchy infiltration; 6 cases, nodular or mass like densities; 2 cases, disseminated nodular or military patterns; 2 cases, and reticular pattern; 1 case. 4. Bronchogram revealed no contributable findings except one case of complete tappering obstruction of the segmental bronchus. Therefore we arrive at the conclusion that early diagnosis will result in increased resectability and improved survival so aggressive diagnostic work-up for suspicious pulmonary infiltrate is necessary

    Full Text Available Abstract Introduction We present the case of a patient with two tumors in his left kidney and a synchronous colon cancer. While coexisting tumors have been previously described in the same kidney or the kidney and other organs, or the colon and other organs, to the best of our knowledge no such concurrency of three primary tumors has been reported in the literature to date. Case presentation A 72-year-old man of Greek nationality presenting with pain in the right hypochondrium underwent a series of examinations that revealed gallstones, a tumor in the hepatic flexure of the colon and an additional tumor in the upper pole of the left kidney. He was subjected to a right hemicolectomy, left nephrectomy and cholecystectomy, and his postoperative course was uneventful. Histopathology examinations showed a mucinous colon adenocarcinoma, plus two tumors in the left kidney, a papillary renal cell carcinoma and a chromophobe renal cell carcinoma. Conclusion This case underlines the need to routinely scan patients pre-operatively in order to exclude coexisting tumors, especially asymptomatic renal tumors in patients with colorectal cancer, and additionally to screen concurrent tumors genetically in order to detect putative common genetic alterations.

  17. Systemic Chemotherapy for Advanced Hepatocellular Carcinoma: Past, Present, and Future

    Full Text Available Systemic chemotherapy is one of the most important treatment modalities for advanced hepatocellular carcinoma (HCC. Before the introduction of sorafenib, cytotoxic agents, hormonal therapies, or many combinations of these were the mainly used modalities for systemic chemotherapy of advanced HCC. However, such regimens were of only limited value in clinical practice, because some randomized controlled studies comparing promising regimens with no treatment or doxorubicin alone failed to show any overall survival advantage. In two pivotal phase III placebo-controlled studies, the SHARP trial and the Asia-Pacific trial, sorafenib was demonstrated to significantly delay the time to progression and the overall survival time in patients with advanced HCC. Therefore, sorafenib therapy has come to be acknowledged as a standard therapy for advanced HCC worldwide. After the introduction of sorafenib, a number of phase III trials of various molecular-targeted agents vs. sorafenib as first-line chemotherapy and of various molecular-targeted agents vs. placebo as second-line chemotherapy have been conducted to determine if any of these agents could offer a survival benefit, however, none of the agents examined so far has been demonstrated to provide any survival benefit over sorafenib or placebo. Recently, favorable treatment efficacies have been reported in some clinical trials of molecular-targeted agents in the biomarker-enriched population. Development of individualized cancer treatments using molecular-targeted agents based on the results of genome-sequencing is aggressively ongoing. Furthermore, immune-oncologic agents, such as anti-CTLA-4 antibody and anti-PD-1/PD-L1 antibody, have been reported to provide promising outcomes. Thus, various novel systemic chemotherapeutic agents are currently under development, and further improvements in the treatment outcomes are expected.

    Recent clinical trials have revealed that accurate histologic typing of non-small cell lung cancer is essential. Until now, squamous cell carcinoma (SQC) and adenocarcinoma (ADC) markers have not been thoroughly analyzed for pulmonary neuroendocrine carcinomas (NECs). We analyzed the expression of 8 markers [p63, cytokeratin (CK) 5/6, SOX2, CK7, desmocollin 3, thyroid transcription factor-1 (8G7G3/1 and SPT24), and napsin A] in 224 NECs. SOX2 (76.2%) had the greatest expression for NECs. CK5/6 (1.4%), desmocollin 3 (0.5%), and napsin A (0%) were expressed less or not at all in NECs. Although our investigated markers have been reported useful for differentiating between SQC and ADC, some of them were also present in a portion of pulmonary NECs. In our study, CK5/6 and desmocollin 3 were highly specific markers for SQC, and napsin A was highly specific for ADC. These markers are recommended for diagnosis of poorly differentiated non-small cell lung cancer. PMID:23060301

    Full Text Available Abstract Background Novel therapies are necessary to improve outcomes for patients with squamous cell carcinomas (SCC of the head and neck. Historically, vaccinia virus was administered widely to humans as a vaccine and led to the eradication of smallpox. We examined the therapeutic effects of an attenuated, replication-competent vaccinia virus (GLV-1h68 as an oncolytic agent against a panel of six human head and neck SCC cell lines. Results All six cell lines supported viral transgene expression (β-galactosidase, green fluorescent protein, and luciferase as early as 6 hours after viral exposure. Efficient transgene expression and viral replication (>150-fold titer increase over 72 hrs were observed in four of the cell lines. At a multiplicity of infection (MOI of 1, GLV-1h68 was highly cytotoxic to the four cell lines, resulting in ≥ 90% cytotoxicity over 6 days, and the remaining two cell lines exhibited >45% cytotoxicity. Even at a very low MOI of 0.01, three cell lines still demonstrated >60% cell death over 6 days. A single injection of GLV-1h68 (5 × 106 pfu intratumorally into MSKQLL2 xenografts in mice exhibited localized intratumoral luciferase activity peaking at days 2–4, with gradual resolution over 10 days and no evidence of spread to normal organs. Treated animals exhibited near-complete tumor regression over a 24-day period without any observed toxicity, while control animals demonstrated rapid tumor progression. Conclusion These results demonstrate significant oncolytic efficacy by an attenuated vaccinia virus for infecting and lysing head and neck SCC both in vitro and in vivo, and support its continued investigation in future clinical trials.

  1. SPINDLE CELL CARCINOMA OF MAXILLA:CASE REPORT OF A RARE ENTITY AND REVIEW OF LITERATURE

    Directory of Open Access Journals (Sweden)

    Ajish M. Saji

    2013-07-01

    Full Text Available Spindle cell Carcinoma is a rare biphasic neoplasm consisting of epithelial andmesenchymal components and accounts for less than 1% of all tumours of oralregion. It is a rare aggressive variant of squamous cell carcinoma which frequentlyrecurs and metastasizes with poor prognosis compared to classical squamous cellcarcinoma. The biologic behaviour is comparable to poorly differentiated SquamousCell Carcinoma. The 5 year disease free survival rate is approximately 30% for all OralTumors. The variants of squamous cell carcinoma frequently arise in mucosa of upperaerodigestive tract. The most common site in head and neck region is in larynx andhypopharynx; the oral cavity being rarely affected. This biphasic malignant neoplasmoften assumes a sarcomatous appearance and may present diagnostic difficulty. Hencecareful histopathologic analysis is warranted. We report a rare case of spindle cellcarcinoma in unusual location with immunohistochemical findings and review of theliterature.

    Concomitant infection with Aspergillus species and cervical squamous cell carcinoma in the female genital tract is a rare occurrence and attributed to the opportunistic nature of infection in the immunocompromised state due to the underlying malignancy. The contamination of smears with Aspergillus species should be excluded. The diagnosis of Aspergillus species infection along with squamous cell carcinoma was established on cervicovaginal pap smears in a 62-year-old female presented to gynecological clinic with complaints of stress urinary incontinence. Speculum examination revealed first-degree cervical descent. Smears showed features of squamous cell carcinoma along with fungal spores and fruiting body with hyphae of Aspergillus species. The presence of fruiting bodies and hyphae of Aspergillus species with coexisting squamous cell carcinoma is rare in routine pap smears. True infection needs to be distinguished from contamination by Aspergillus species. Early diagnosis can be established on routine cervicovaginal Pap smear examination. PMID:24272933

    Full Text Available Abstract Background We aimed to estimate whether the macroscopic extent of gastric mucosal atrophy is associated with a risk for esophageal squamous cell carcinoma using a case-control study in Japanese subjects, a population known to have a high prevalence of CagA-positive H. pylori infection. Methods Two hundred and fifty-three patients who were diagnosed as having esophageal squamous cell carcinoma, and 253 sex- and age-matched controls were enrolled in the present study. The macroscopic extent of gastric mucosal atrophy was evaluated based on the Kimura and Takemoto Classification. A conditional logistic regression model with adjustment for potential confounding factors was used to assess the associations. Results Body gastritis, defined endoscopically, was independently associated with an increased risk for esophageal squamous cell carcinoma. Conclusion Our findings suggest that macroscopic body gastritis may be a risk factor for esophageal squamous cell carcinoma in Japan. Further studies are needed to confirm these findings.

    Full Text Available Gardners syndrome (GS is a variant of familial adenomatous polyposis (FAP and presents with both colonic and extra colonic manifestations. It is an autosomal dominant disorder and results from mutations in adenomatous polyposis coli (APC gene. Patients with GS if not treated early will invariably develop colonic cancers at a much younger age than those with sporadic colonic carcinoma. These patients also develop other malignant tumours like duodenal cancers, gastric cancer, hepatoblastoma, papillary carcinoma of the thyroid and multifocal cholangiocarcinomas. With early diagnosis and treatment of colonic polyposis, adenocarcinoma of the duodenum has become the leading cause of death in FAP patients. The mean age at which duodenal carcinoma is diagnosed in FAP is 45-52 years. We report the rare occurrence of duodenal carcinoma as the presenting feature of Gardner’s syndrome in a young 25-year-old male with no obvious malignant changes in the colonic adenomas.

    Full Text Available Basal cell carcinoma originates from pluripotent cells of basal layer of epiderm, external covering of hair follicles, sebaceous glands or other skin adnexa. It is characterized by local infiltrating and sometimes destructive growth. There are several types of basal cell carcinomas that may be manifested in over 12 clinical forms. Surgical treatment depends to a large extent on the histological type, localization and its clinical manifestation. The analysis included 250 patients of both gender and different age, operated for basal cell carcinoma. Clinical characteristics of basal cell carcinoma and the width of the excision were described. It was concluded that the width of the excision of basal cell cancer was in relation to histological type. .

  6. Perineural Infiltration of Cutaneous Squamous Cell Carcinoma and Basal Cell Carcinoma Without Clinical Features

    International Nuclear Information System (INIS)

    Purpose: To review the factors that influence outcome and patterns of relapse in patients with cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with perineural infiltration (PNI) without clinical or radiologic features, treated with surgery and radiotherapy. Methods and Materials: Between 1991 and 2004, 222 patients with SCC or BCC with PNI on pathologic examination but without clinical or radiologic PNI features were identified. Charts were reviewed retrospectively and relevant data collected. All patients were treated with curative intent; all had radiotherapy, and most had surgery. The primary endpoint was 5-year relapse-free survival from the time of diagnosis. Results: Patients with SCC did significantly worse than those with BCC (5-year relapse-free survival, 78% vs. 91%; p < 0.01). Squamous cell carcinoma with PNI at recurrence did significantly worse than de novo in terms of 5-year local failure (40% vs. 19%; p < 0.01) and regional relapse (29% vs. 5%; p < 0.01). Depth of invasion was also a significant factor. Of the PNI-specific factors for SCC, focal PNI did significantly better than more-extensive PNI, but involved nerve diameter or presence of PNI at the periphery of the tumor were not significant factors. Conclusions: Radiotherapy in conjunction with surgery offers an acceptable outcome for cutaneous SCC and BCC with PNI. This study suggests that focal PNI is not an adverse feature.

    Full Text Available Abstract Background Squamous cell carcinoma of the scrotum is rare and its development in the scar of Fournier's gangrene is still rarer. Case presentation A 65-year-old gentleman presented with a small non-healing ulcer developing on right hemi-scrotum two years after the treatment for Fournier's gangrene. On histological examination it was found to be squamous cell carcinoma. He was successfully managed by surgery in the form of wide local excision and ilio-inguinal lymph node dissection followed by adjuvant radiotherapy and chemotherapy. Conclusions Squamous cell carcinoma can develop in the scar of Fournier's gangrene after a long delay, which differentiates it from other scar carcinomas or Marjolin's ulcer.

    Treatment of renal cell carcinoma has evolved considerably over the last few years. While total nephrectomy is necessary at times, nephron-sparing surgery, with a goal of renal function preservation, should always be considered. Although open partial nephrectomy is considered the gold standard approach for nephron-sparing surgery, laparoscopic- or robotic-assisted techniques allow urologists to perform renal surgery less invasively, with excellent long-term oncological outcomes. Cryotherapy and radiofrequency ablation are less invasive management approaches for carefully selected patients with small renal masses. Active surveillance should be considered in elderly or patients who are unfit for surgery. Ultimately, the method chosen for management of a renal mass is an informed decision made by the physician and patient. PMID:26892144

    Small cell carcinoma of the gall bladder (SCCGB) is a rare condition, with only 53 prior cases reported in the world literature when our case was first diagnosed. Our patient was found to have limited stage disease and was treated with sequential laparoscopic cholecystectomy, etoposide/carboplatin chemotherapy followed by consolidating loco-regional radiation therapy. She is alive and well without evidence of disease more than 132 months since diagnosis. We describe here our experience in the diagnosis, staging workup, treatment, and surveillance of a case of SCCGB and review the published literature. Treated aggressively with currently available methods, patients with limited stage SCCGB can have an excellent prognosis. The authors' intent is to provide a reasonable plan of treatment for other physicians facing such an unusual patient. PMID:27197345

    This review provides an overview of the incidence of renal cell carcinoma (RCC) and a summary of the most commonly associated risk factors. A literature review was performed with a focus on recent studies with a high level of evidence (large prospective cohort studies and meta-analyses). The incidence rate of RCC varies globally, with the rate rising rapidly in more developed regions, demonstrating the effects of increased use of diagnostic imaging and prevalence of modifiable risk factors. Based on the current evidence, cigarette smoking, obesity, and hypertension are the most well-established risk factors for sporadic RCC worldwide. Acquired cystic kidney disease is also a significant risk factor, specifically in dialysis patients. There is increasing evidence for an inverse association between RCC risk and moderate alcohol consumption. Certain analgesics and occupational exposure have been linked to an increased risk of RCC, although data are limited. Diets rich in fruits and vegetables may provide a protective effect.

    Targeted therapies have fundamentally altered the therapy of metastatic renal cell carcinoma (mRCC). Sunitinib today is an internationally recommended reference standard in first-line therapy; other drugs such as Temsirolimus, Everolimus, Bevacizumab (in combination with Interferon-alpha) and Sorafenib are part of the therapeutic arsenal. Practitioners thus have now more and better therapeutic options at hand, leading to a significantly improved prognosis for mRCC patients. Numerous ongoing research activities aim at the improvement of the benefits of the new compounds in the metastatic situation or application earlier in the course of the disease. Key aspects of future development in RCC are the optimization of the current therapy options by developing new targeted therapies, the search for the best combinations and sequences including the role of nephrectomy and the assessment in the adjuvant or neo-adjuvant setting. The following contribution provides an overview of ongoing studies, thus giving insight into the future therapy of RCC. PMID:20164673

    2008-02-01

    Full Text Available Abstract Background The head and neck/oral squamous cell carcinoma (HNOSCC is a diverse group of cancers, which develop from many different anatomic sites and are associated with different risk factors and genetic characteristics. The oral tongue squamous cell carcinoma (OTSCC is one of the most common types of HNOSCC. It is significantly more aggressive than other forms of HNOSCC, in terms of local invasion and spread. In this study, we aim to identify specific transcriptomic signatures that associated with OTSCC. Results Genome-wide transcriptomic profiles were obtained for 53 primary OTSCCs and 22 matching normal tissues. Genes that exhibit statistically significant differences in expression between OTSCCs and normal were identified. These include up-regulated genes (MMP1, MMP10, MMP3, MMP12, PTHLH, INHBA, LAMC2, IL8, KRT17, COL1A2, IFI6, ISG15, PLAU, GREM1, MMP9, IFI44, CXCL1, and down-regulated genes (KRT4, MAL, CRNN, SCEL, CRISP3, SPINK5, CLCA4, ADH1B, P11, TGM3, RHCG, PPP1R3C, CEACAM7, HPGD, CFD, ABCA8, CLU, CYP3A5. The expressional difference of IL8 and MMP9 were further validated by real-time quantitative RT-PCR and immunohistochemistry. The Gene Ontology analysis suggested a number of altered biological processes in OTSCCs, including enhancements in phosphate transport, collagen catabolism, I-kappaB kinase/NF-kappaB signaling cascade, extracellular matrix organization and biogenesis, chemotaxis, as well as suppressions of superoxide release, hydrogen peroxide metabolism, cellular response to hydrogen peroxide, keratinization, and keratinocyte differentiation in OTSCCs. Conclusion In summary, our study provided a transcriptomic signature for OTSCC that may lead to a diagnosis or screen tool and provide the foundation for further functional validation of these specific candidate genes for OTSCC.

  18. Ultrastructural proof of polyomavirus in Merkel cell carcinoma tumour cells and its absence in small cell carcinoma of the lung.

    Directory of Open Access Journals (Sweden)

    Charlotte T A H Wetzels

    Full Text Available BACKGROUND: A new virus called the Merkel Cell Polyomavirus (MCPyV has recently been found in Merkel Cell Carcinoma (MCC. MCC is a rare aggressive small cell neuroendocrine carcinoma primarily derived from the skin, morphologically indistinguishable from small cell lung carcinoma (SCLC. So far the actual presence of the virus in MCC tumour cells on a morphological level has not been demonstrated, and the presence of MCPyV in other small cell neuroendocrine carcinomas has not been studied yet. METHODOLOGY/PRINCIPAL FINDINGS: We investigated MCC tissue samples from five patients and SCLCs from ten patients for the presence of MCPyV-DNA by PCR and sequencing. Electron microscopy was used to search ultrastructurally for morphological presence of the virus in MCPyV-DNA positive samples. MCPyV was detected in two out of five primary MCCs. In one MCC patient MCPyV-DNA was detected in the primary tumour as well as in the metastasis, strongly suggesting integration of MCPyV in the cellular DNA of the tumour in this patient. In the primary MCC of another patient viral particles in tumour cell nuclei and cytoplasm were identified by electron microscopy, indicating active viral replication in the tumour cells. In none of the SCLCs MCPyV-DNA was detected. CONCLUSIONS/SIGNIFICANCE: Our results strongly suggest that MCPyV is an oncogenic polyomavirus in humans, and is potentially causally related to the development of MCC but not to the morphological similar SCLC.

The latter, also known as malignant AN, is mostly related to abdominal neoplasms. Malignant AN occurs frequently among elderly patients. In these cases, the onset is subtle, and spreading involves the flexural regions of the body, particularly the axillae, palms, soles, and mucosa. Gastric adenocarcinoma is the most frequent associated neoplasia, but many others have been reported. Renal cell carcinoma (RCC), although already reported, is rarely associated with malignant AN. The authors report the case of a woman who was being treated for depression but presented a long-standing and marked weight loss, followed by darkening of the neck and the axillary regions. Physical examination disclosed a tumoral mass in the left flank and symmetrical, pigmented, velvety, verrucous plaques on both axillae, which is classical for AN. The diagnostic work-up disclosed a huge renal mass, which was resected and further diagnosed as a RCC. The post-operative period was uneventful and the skin alteration was evanescent at the first follow-up consultation. The authors call attention to the association of AN with RCC. PMID:27284539

    Full Text Available On the basis of multidimensional and comprehensive molecular characterization (including DNA methalylation and copy number, RNA, and protein expression, we classified 894 renal cell carcinomas (RCCs of various histologic types into nine major genomic subtypes. Site of origin within the nephron was one major determinant in the classification, reflecting differences among clear cell, chromophobe, and papillary RCC. Widespread molecular changes associated with TFE3 gene fusion or chromatin modifier genes were present within a specific subtype and spanned multiple subtypes. Differences in patient survival and in alteration of specific pathways (including hypoxia, metabolism, MAP kinase, NRF2-ARE, Hippo, immune checkpoint, and PI3K/AKT/mTOR could further distinguish the subtypes. Immune checkpoint markers and molecular signatures of T cell infiltrates were both highest in the subtype associated with aggressive clear cell RCC. Differences between the genomic subtypes suggest that therapeutic strategies could be tailored to each RCC disease subset.

Liver CSCs have emerged as an important therapeutic target against HCC. Numerous surface markers for liver CSCs have been identified, and include CD133, CD90, CD44, CD13, and epithelial cell adhesion molecules. These surface markers serve not only as tools for identifying and isolating liver CSCs but also as therapeutic targets for eradicating these cells. In studies of animal models and large-scale genomic analyses of human HCC samples, many signaling pathways observed in normal stem cells have been found to be altered in liver CSCs, which accounts for the stemness and aggressive behavior of these cells. Antibodies and small molecule inhibitors targeting the signaling pathways have been evaluated at different levels of preclinical and clinical development. Another strategy is to promote the differentiation of liver CSCs to less aggressive HCC that is sensitive to conventional chemotherapy. Disruption of the tumor niche essential for liver CSC homeostasis has become a novel strategy in cancer treatment. To overcome the challenges in developing treatment for liver CSCs, more research into the genetic makeup of patient tumors that respond to treatment may lead to more effective therapy. Standardization of HCC CSC tumor markers would be helpful for measuring the CSC response to these agents. Herein, we review the current strategies for developing treatment to eradicate liver CSCs and to improve the outcome for patients with

    Basal cell carcinoma is the most common malignant skin tumour. Chronic sun exposure is considered as the main etiologic factor in its development. Although it mainly occurs on sun-exposed areas as the face and neck, it rarely develops on the forearms and/or arms. The etiologic factors which affect the anatomic distribution of basal cell carcinoma are not well-known. Here we report two patients who developed basal cell carcinoma on the forearm. None of the patients had a specific etiologic fac...

    A 70-year-old Japanese man presented at our hospital with an asymptomatic, blackish, irregularly shaped plaque with a gray nodule in the periphery on his left lower leg. The lesion had been present for 10 years and had recently enlarged, associated with bleeding. Histopathologically, the tumor consisted of three distinct parts: The first part showed massive aggregation of basophilic basaloid cells with peripheral palisading and abundant melanin granules, and was diagnosed as solid-type basal cell carcinoma. The second part showed aggregation of clear cells with squamous eddies, and was diagnosed as proliferating trichilemmal tumor. The third part showed reticular aggregation of basaloid cells with infundibular cysts in the papillary dermis, and was diagnosed as infundibulocystic basal cell carcinoma. We diagnosed this tumor as basal cell carcinoma with various forms of hair follicle differentiation, including differentiation into the outer root sheath. PMID:26955331

    We report a 12-year-old female with a history of mixed germ cell carcinoma of the right ovary who developed a generalized skin rash after oophorectomy and chemotherapy. She also presented with periodic episodes of flushing, anemia, tachycardia, shortness of breath, high fever, hepatosplenomegaly, nausea, abdominal cramping with diarrhea, and a papuloerythematous skin rash. There was no evidence of secondary carcinoma. Skin biopsy revealed nonspecific inflammatory cells with negative staining for mast cells. Peripheral blood smear showed an increased number of mast cells, thrombocytopenia and normal white cells count. Bone marrow showed hypercellularity with 38% of the nucleated cells being mast cells. Bone marrow chromosome analysis revealed hyperdiploidy in 30% of the cells: 58-64,XX, +1, +2, +5, +6, +7, +8, +14, +16, +18, +19, +19, +20, +21, +22. She expired two months after the occurrence of systemic mastocytosis. Systemic mastocytosis has been reported in association with hematopoietic disorders and with germ cell tumors. The association between mediastinal germ cell tumors and hematological malignancies has also been observed. To our knowledge, combination of most cell leukemia, systemic mastocytosis, and ovarian germ cell carcinoma has not been observed. It is know that mutations at the locus of either proto-oncogene c-kit receptor or its ligand, mast/stem cell factor (SCF) may impair the development of three stem cell populations: hematopoietic stem cells, germ cells and melanoblasts. There have been also extensive investigations on the expression and modulation of the SCF/c-kit interaction in various malignancies. Further molecular studies in patients with germ cell tumor/hematopoietic malignancy syndrome are required to delineate underlying mechanisms.

    Full Text Available Abstract Background The incidence of multiple primary malignant neoplasms increases with age and they are encountered more frequently nowadays than before, the phenomenon is still considered to be rare. Case presentation We report a case of a man in whom urinary bladder transitional cell carcinoma, metachronous prostate adenocarcinoma and small cell lung carcinoma were diagnosed within an eighteen-month period. The only known predisposing factor was that he was heavy smoker (90–100 packets per year. The literature on the phenomenon of multiple primary malignancies in a single patient is reviewed and the data is summarized. Conclusion It is important for the clinicians to keep in mind the possibility of a metachronous (successive or a synchronous (simultaneous malignancy in a cancer patient. It is worthy mentioning this case because clustering of three primary malignancies (synchronous and metachronous is of rare occurrence in a single patient, and, to our knowledge, this is the first report this combination of three carcinomas appearing in the same patient.

  16. Comparative study of MRI appearances in clear cell renal cell carcinoma, papillary renal cell carcinoma and chromophobe renal cell carcinoma

    International Nuclear Information System (INIS)

    Objective: To investigate the differential diagnostic features of subtypes of renal cell carcinoma (RCC) using dynamic contrast-enhanced MRI(DCE-MRI). Methods: The MRI appearances of 77 RCCs, including 55 clear cell RCCs (CCRCC), 14 papillary RCCs (PRCC) and 8 chromophobe RCCs (CRCC), were retrospectively analyzed and compared with findings of pathology. DCE-MRI was conducted in each case after intravenous administration of contrast agent. Region of interest measurements (cortical, nephrographic and delayed Phases) of signals within tumor and uninvolved renal cortex were used to calculate percentage signal intensity change and tumor-to-cortex enhancement index, and the data was analyzed by AVONA and t test. Results: On unenhanced and enhanced MRI, most CRCCs showed homogeneous signal (7/8). CCRCC and PRCC often show inhomogeneous signal with necrosis (36/55, 7/14). Hemorrhage and cystic degeneration were often found in PRCC (9/14). On the cortical, nephrographic and delayed phase images, CCRCCs showed greater signal intensity change [(296.15± 60.27)%, (236.33±58.31)% and (216.83±46.72)%, respectively than PRCCs (79.70±18.84)%, (122.81±27.35)% and (117.55±20.63)%, respectively], and CRCCs showed intermediate change [(119.56±40.76)%, (163.06±33.91)% and (179.72±32.89)%, respectively]. A phenomenon of quick staining and quick fainting was observed in CCRCCs. Both of CRCCs and PRCCs showed delayed enhancement. The tumor-to-cortex enhancement index at the cortical, nephrographic and delayed phases was highest for CCRCCs (1.26±0.34, 0.92±0.23 and 0.76±0.14, respectively), lowest for PRCCs (0.33±0.12, 0.41±0.23 and 0.35±0.11, respectively), and intermediate for CRCCs (0.54±0.10, 0.62±0.15 and 0.69±0.12, respectively, P<0.01). The degree of enhancement was significantly different among the 3 subtypes at the every contrast enhanced phase (F= 940.931, 124.515 and 38.194, P<0.01), so was the tumor-to-cortex enhancement index (F=798.625, 78.308 and 73.699, P

    The purpose of this study was to investigate the anticancer effect of aloe-emodin, an anthraquinone compound present in the leaves of Aloe vera, on two distinct human gastric carcinoma cell lines, AGS and NCI-N87. We demonstrate that aloe-emodin induced cell death in a dose- and time-dependent manner. Noteworthy is that the AGS cells were generally more sensitive than the NCI-N87 cells. Aloe-emodin caused the release of apoptosis-inducing factor and cytochrome c from mitochondria, followed by the activation of caspase-3, leading to nuclear shrinkage and apoptosis. In addition, exposure to aloe-emodin suppressed the casein kinase II activity in a time-dependent manner and was accompanied by a reduced phosphorylation of Bid, a downstream substrate of casein kinase II and a pro-apoptotic molecule. These preclinical studies suggest that aloe-emodin represents a suitable and novel chemotherapeutic drug candidate for the treatment of human gastric carcinoma. PMID:17637488

    Full Text Available Basal cell and squamous cell carcinoma of skin are common tumors which can be easily distinguished on hematoxylin and eosin stained sections, but basosquamous carcinoma is a controversial entity. The aim of our study was to distinguish basal cell carcinoma and basosquamous carcinoma using Ber-EP4, immunohistochemically in 52 skin tumors. Twenty basal cell carcinomas, 20 squamous cell carcinomas, 10 basosquamous carcinomas and 2 collision tumors of the skin were stained with Ber-EP4 immunohistochemically. All basal cell carcinomas were stained strongly and diffusely with Ber-EP4, whereas squamous cell carcinomas were not, and basosquamous carcinomas were partially stained. Our results suggest that, distinction of basal cell carcinoma and basosquamous carcinoma can be achieved with routine immunohistochemical Ber-EP4 staining.

    AIM: To study the viscoelastic properties of humanhepatocytss and helatocellulsr carcinoma (HCC) cellsunder cytoslelstal perturbation, and to further to study theviscoelastic properties and the adhesive properties of mousehepatorna cells (HTC) in different cell cycls.METHODS: Micropipette aspiration technique was adopted tomeasure viscoelastic coefficients and adhesion force tocollagen coated surface ofthe cells. Three kinds ofcytoskeleton perturbing agents, colchiclnes (Col),cytochalssin D (CD) and vinblastine (VBL), were used totreat HCC cells and hepatocytes and the effects of thesetreatent on cell viscoelastic coefficients were investigated.The experimental results were analyzed with a thres-elsmentstandard linear solid. Further, the viscoelastic properties ofHTC cells and the adhesion force of different cycle HTC cellswere also investigated. The synchronous G1 and S phasecells were achieved through thymine-2-desoryriboside andcolchicines sequential blockage method and thymine-2-desoryriboside blockage method respectively.RESULTS: The elastic coefficients, but not viscouscoefficient of HCC cells (k1 = 103.6± 12.6N.m-2, k2 =42.5±10.4N. m-2, μ = 4.5 ± 1.9Pa. s), were significantly higherthan the corresponding value for hepatocytes (K1 = 87.5 ±12.1N.m-2, k2 =33.3± 10.3N.m-2, μ=5.9±3.0Pa. s, P<0.01). Upon treatment with CD, the viscoelastic coefficients ofboth hepotocytes and HCC cells decreased consistently,with magnitudes for the decrease in elastic coefficients ofHCC cells (k1: 68.7 N.m-2 to 81.7N.m-2, 66.3 % to 78.9 %;k2: 34.5 N.m-2 to37.1N.m-2, 81.2% to 87.3 %, P<0.001)larger than those for normal hepatocytes (k1: 42.6N. m-2 to49.8N.nt-2, 48.7% to56.9 %; k2: 17.2N.m-2 to 20.4N.m-2,51.7 % to 61.3 %, P< 0.001). There was a little decrease inthe vlscous coefficient of HCC cells (2.0 to 3.4Pa. s, 44.4 to75.6 %, P<0.001) than that for hepatocytes (3.0 to 3.gPa.s, 50.8to 66.1% P<0.001). Upon trastment with Col andVBL, the elastic coefficients
