    This report describes a rare occurrence of a subcutaneous metastatic bronchogenic carcinoma to the distal fingertip. The original clinical presentation suggested an infectious process. Subsequent roentgenograms, sterile cultures, and positive biopsy material revealed that the lesion started as a subcutaneous metastasis that secondarily involved adjacent bone. Amputation of the digit was performed.

    Full Text Available The objective of this study was to present some clinical and radiological manifestations of PNS in relation to bronchogenic carcinoma (BC and to evaluate the usefulness of imaging findings in the diagnosis of asymptomatic BC. In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

    Full Text Available Cardiac metastases in bronchogenic carcinoma may occur due to retrograde lymphatic spread or by hematogenous dissemination of tumour cells, but direct invasion of heart by adjacent malignant lung mass is very uncommon. Pericardium is frequently involved in direct cardiac invasion by adjacent lung cancer. Pericardial effusion, pericarditis, and tamponade are common and life threatening presentation in such cases. But direct invasion of myocardium and endocardium is very uncommon. Left atrial endocardium is most commonly involved in such cases due to anatomical contiguity with pulmonary hilum through pulmonary veins, and in most cases left atrial involvement is asymptomatic. But myocardial compression and invasion by adjacent lung mass may result in myocardial ischemia and may present with retrosternal, oppressive chest pain which clinically may simulate with the acute myocardial infarction (AMI. As a result, it leads to misdiagnosis and delayed diagnosis of lung cancer. Here we report a case of non-small-cell carcinoma of right lung which was presented with asymptomatic invasion in left atrium and retrosternal chest pain simulating AMI due to myocardial compression by adjacent lung mass, in a seventy-four-year-old male smoker.

    To analyze the internal and peripheral textures of small peripheral bronchogenic carcinomas (analysis. Thin-section computed tomography images from 70 patients with bronchogenic carcinomas (61 adenocarcinomas and 9 squamous cell carcinomas) were used. Regions of interest (ROIs) with a matrix size of 32 x 32 (0.326 mm per pixel) were selected manually on the lung-nodule interfaces and within the nodules on HRCT images. Three-dimensional density surfaces based on CT values of ROIs were characterized by fractal dimensions (FDs). When all the bronchogenic carcinomas were divided into bronchioloalveolar cell carcinomas (BACs) and other bronchogenic carcinomas (nonBACs), there were significant differences between BACs and nonBACs in the FDs obtained from the internal textures (mean: 2.38 +/- 0.05 versus 2.19 +/- 0.05; Ptextures (mean: 2.16 +/- 0.01 versus 2.06 +/- 0.01; Ptextures of BACs that reveal ground-glass opacities are more complicated than those of nonBACs. The FDs can differentiate between small localized BACs, which have a good prognosis, and nonBACs, which have a poor prognosis. Fractal analysis is promising for characterization of small peripheral pulmonary bronchogenic carcinomas based on radiographic features of HRCT images.

    Full Text Available Abstract Introduction Double primary bronchogenic carcinoma and papillary carcinoma of the thyroid are extremely rare. We describe the case of a patient who underwent surgical resection for these two cancers. Case presentation A 56-year-old man presented to our hospital complaining of a cough with blood-tinged sputum. A slowly growing mass in the left lobe of the lung had been noted for about 1 year. He underwent video-assisted thoracic surgery of the left lower lobe and mediastinal lymph node dissection through an 8 cm utility incision. Pathology revealed a well-differentiated adenocarcinoma and the dissected lymph nodes were negative for malignancy. He also complained of a mass in his neck, which had grown slowly for over 5 years. A computed tomography scan of the neck revealed a left thyroid mass compressing the trachea towards the right side. There was no cervical lymphadenopathy. A left thyroid lobectomy was performed and pathology revealed a papillary carcinoma. Thus, he underwent a second operation to remove the right lobe of the thyroid. He underwent subsequent adjuvant chemotherapy. Conclusion In a review of the literature, it appears that there has only been one previously reported case of these two cancers, which was in Japan. The relationship between these two cancers is still unclear, and more case reports are required to determine this relationship.

    Full Text Available Concentrations of carcinoembryonic antigen (CEA and carbon hydrate antigen (CA 50 were measured in pleural effusion and sera of 57 patients with bronchogenic carcinoma and in 73 patients in whom the effusion was the sequelae of tuberculosis pleurisy. In the group with bronchogenic carcinomas plan cellular was confirmed in 19, micro cellular in 17, macro cellular in 2 and adenocarcinoma in 18, while in 1 patient it was not possible to determine the histopathologic structure. The diagnosis of pleural disease was established upon the cytologic examination of the effusion and histopathologic examination of the pleural sample obtained by blind percutaneous needle biopsy or following pleuroscopy. CEA concentration in the sera of patients with bronchogenic carcinoma was significantly higher than in the patients with tuberculosis (p<0.001, with sensitivity of 44% and ideal specificity and positive predictive value of 100%. In the same group highly significant difference of mean values of CEA concentrations in pleural effusion (p<0.001, was also found with sensitivity of 60%, significant specificity of 99% and positive predictive value of 97%. CA 50 concentrations in the sera of patients with lung carcinoma were significantly higher than those in the sera of patients with tuberculosis pleurisy (p<0.05, and the sensitivity was 50%, while the specificity was 94% and positive predictive value was 75%. Significantly higher was also the value in the pleural effusion (p<0.05, but the sensitivity was slightly lower - 40%, but specificity was favorable as well as the positive predictive value (94 and 86%, respectively. The results indicate the significance of the determination of CEA and CA 50 in the sera and pleural effusion in the differentiation of malignant from tuberculosis pleural effusion.

    We describe the case of a 60 year old female smoker who presented with a three month history of weight loss (14 Kg), generalized abdominal discomfort and malaise. Chest radiography demonstrated a mass projected inferior to the hilum of the right lung. Computed Tomography of thorax confirmed a lobulated lesion in the right infrahilar region and subsequent staging abdominal CT demonstrated a low density lesion in the neck of the pancreas. Percutaneous Ultrasound guided pancreatic biopsy was performed, histology of which demonstrated pancreatic tissue containing a highly necrotic small cell undifferentiated carcinoma consistent with metastatic small cell carcinoma of the bronchus.

    Full Text Available Background: The importance of rapid and accurate cytopathological diagnosis in bronchial cancers is increasing due to advances in treatment modalities. Aims: We evaluated the diagnostic methods and cytologic subtypes of bronchial cancers to determine the diagnostic reliability of different bronchoscopic techniques. Material and methods: Retrospective data were obtained from the hospital files and pathological specimens of the patients with diagnosis of primary lung cancer from a period of 36 months. Cytological tumor typing was determined using histopathology of bronchoscopic forceps biopsy (FB, bronchial-bronchoalveolar lavage (BL, bronchial brushing (BB, transbronchial fine-needle biopsy. Computed tomography or ultrasonography guided transthoracic biopsy and surgical biopsies were used where the other interventional methods were inadequate for diagnosis. Results: A total of 124 patients were diagnosed during study period. 119 (96% of them were male. The median age was 68, ranging between 36 and 88 years. Histopathologic subtypes were determined as non-small cell carcinoma (NSCC in 104 (83.9%, squamous cell carcinoma in 64 (51.6%, adenocarcinoma in 16 (12.9%, NSCC not otherwise specified in 24 (19.3% and small cell carcinoma in 20 (16.1% patients. The combination of FB, BL and BB established the diagnosis of bronchogenic carcinoma in most of the cases (92.6%. Conclusions: Lung cancer is seen commonly in elderly male patients with smoking history and squamous cell carcinoma is the most common cytologic type. High diagnostic accuracy can be achieved by a combination of bronchoscopic FB, BB and BL procedures.   Keywords: Bronchoscopy; Lung cancer; Bronchial brushing

  11. Round pneumonia: a rare condition mimicking bronchogenic carcinoma. Case report and review of the literature

    Directory of Open Access Journals (Sweden)

    José Jesus de Peixoto Camargo

    Full Text Available CONTEXT: Round pneumonia is a condition usually described in children, with few reports addressing adult patients. It is an oval-shaped consolidation that, due to its radiological appearance, simulates bronchogenic carcinoma. Its evolution tends to be benign, although diagnostic dilemmas have sometimes required exploratory thoracotomy. Deaths caused by this condition have even been reported. To the best of our knowledge, there have been 31 previous cases of round pneumonia in adults reported in the English and Portuguese-language literature, of which only one was completely asymptomatic. CASE REPORT: The case of a 54-year-old female patient presenting a lung mass found on routine imaging evaluation is reported. Respiratory symptoms and signs were absent, but the patient had a significant history of smoking. Her physical examination gave normal results. On chest radiographs, a mass located in the middle third of the right lung was observed. Three weeks after the initial evaluation, the patient was admitted for a complete evaluation and for staging of a pulmonary malignancy, but repeated chest radiographs showed complete resolution.

    The synchronous presentation of pulmonary and hepatic nodules in a patient with previously resected bronchogenic carcinoma raises suspicion of recurrence and mandates restaging. We present the case of a 71-year-old male with a history of lobectomy with pericardial resection and mediastinal lymphadenectomy (T3N0M0). At five years after the operation, he presented with a new pulmonary lesion. Restaging detected a synchronous nodule in the liver. Despite the strong suspicion of tumor recurrence, further investigation with a percutaneous liver biopsy revealed hepatocellular carcinoma. In order to investigate the etiology of the pulmonary lesion (hypotheses of recurrent bronchial cancer and of metastatic hepatocellular carcinoma), an open lung biopsy was performed, which revealed chronic inflammatory tissue with foci of anthracosis and dystrophic calcification. The patient was submitted to a non-anatomic resection of the liver lesion. The postoperative course was uneventful, and the patient was discharged on postoperative day 10. This report highlights the relevance of the histopathological diagnosis in patients with a history of bronchogenic carcinoma and suspicion of tumor recurrence. Differential diagnoses and the treatment administered are discussed.

    Intrapleural immunotherapy, radiotherapy and chemotherapy were employed in that sequence in 22 patients with Stage III non-oat cell bronchogenic carcinoma confined to the thorax. Seven patients received intrapleural BCG in a pilot study and 15 were randomized between intrapleural BCG and intrapleural saline. Isoniazid was begun on day 14 and irradiation (3000 rad in 10 fractions) to the primary lesion, mediastinum and ipsilateral supraclavicular nodes was started on day 21. One to two weeks following irradiation, CAMP chemotherapy was initiated (Cyclophosphamide 300 mg/M/sup 2/ iv, d. 1,8; Adriamycin 20 mg/M/sup 2/ iv, d. 1,8; Methotrexate 15 mg/M/sup 2/ iv, d. 1,8 and Procarbazine 100 mg/M/sup 2/ p.o., d. 1 to 10). Chemotherapy was given for a total of six months. Two patients expired prior to radiotherapy (1 tumor progression, 1 myocardial infarction) and 2 patients were lost to follow-up. Nausea, vomiting, alopecia and fatigue were universal side effects of the chemotherapy. Esophagitis occurred in 9 patients, 7 prior to and 2 after initiation of Adriamycin. In only one case did Adriamycin exacerbate a previous radiation esophagitis. No patient developed clinical radiation pneumonitis, although all had eventual radiation fibrosis. Congestive heart failure occurred in 1 patient with known valvular heart disease and responded to diuretics. Three patients developed localized herpes zoster infections. One patient developed radiation myelitis one year after initiating therapy and six months after completing all chemotherapy. The major side effect was leukopenia with relative platelet sparing. Although significant morbidity was encountered in this primarily older patient population (mean age 64.8 years) recall reactions involving irradiated intrathoracic structures were not a significant clinical problem.

    Full Text Available Bronchogenic cysts occur due to the anomalous development of the primitive tracheobronchial tree early in fetal life. They are usually present in middle mediastinum. Rarely, they have been found in other locations. We describe two patients with subcutaneous bronchogenic cysts located over manubrium sterni with special emphasis on the difficulties in pre-operative diagnosis. The two boys were managed by complete excision of the cysts. The children are well on follow-up.

    2011-01-01

    The authors describe a rare case of metastatic bronchogenic adenocarcinoma in a 55-year-old man presenting with concomittant solitary lytic skull lesion and ischaemic stroke. Metastatic bronchogenic carcinoma is known to present as lytic skull lesions. Primary brain tumours are also known to cause ischaemic brain injury. An underlying stroke risk may be exagerated by cranial tumour surgery. Patients with brain tumours are well known to be predisposed to an increased risk of developing thromboembolic disease. It is unusual to see metastatic bronchogenic adenocarcinoma presenting as ischaemic stroke with a background of concomittant cerebral metastasis. The aetio-pathogenesis of this rare occurrence is discussed with a review of literature.

    2017-01-01

    Abstract Subcutaneous bronchogenic cysts have been described rarely, particularly among adolescents. Only a few reports have described the ultrasonographic features of bronchogenic cysts, characterizing them as nonspecific cystic masses with or without internal echogenic foci or debris. Therefore, it is hard to differentiate subcutaneous bronchogenic cysts from other subcutaneous cystic tumors ultrasonographically. We report a case of presternal subcutaneous bronchogenic cyst in an 18-year-old man with unusual ultrasonographic findings. Ultrasonography revealed a small, oval, cystic mass containing a well-circumscribed, heterogeneously hypoechoic, egg-shaped lesion in the dependent portion of the mass within the subcutaneous fat layer overlying the sternum. Surgical excision was performed, and the cystic mass was diagnosed as a bronchogenic cyst. On pathological examination, the internal, heterogeneously hypoechoic, ball-like lesion was found to be mucous material within the cyst. To our knowledge, this is the first reported case of a presternal subcutaneous bronchogenic cyst presenting with a ball-like lesion inside of the cyst. This unusual ultrasonographic feature can be a clue to the diagnosis of subcutaneous bronchogenic cyst. In conclusion, if an anechoic cyst containing an internal, well-circumscribed, hypoechoic ball-like lesion is seen in the presternal subcutaneous fat layer, subcutaneous bronchogenic cyst should be considered in the differential diagnosis of subcutaneous cystic masses.

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Controversy persists as regards the indications and results of surgery in the treatment of patients with stage pIIIA-N2 non-small cell lung cancer (NSCLC). The objective of this study was to analyze the overall survival of a multicentre series of these patients and the role of adjuvant treatment, looking for factors that may define subgroups of patients with an increased benefit from this treatment. A retrospective study was conducted on 287 patients, with stage pIIIA-N2 NSCLC subjected to complete resection, taken from a multi-institutional database of 2.994 prospectively collected consecutive patients who underwent surgery for lung cancer. Adjuvant treatment was administered in 238 cases (82.9%). Analyses were made of the age, gender, histological type, administration of induction and adjuvant chemotherapy and/or radiation therapy treatments. The 5-year survival was 24%, with a median survival of 22 months. Survival was 26.5% among patients receiving with adjuvant treatment, versus 10.7% for those without it (P=.069). Age modified the effect of adjuvant treatment on survival (interaction P=.049). In patients under 70 years of age with squamous cell carcinoma, adjuvant treatment reduced the mortality rate by 37% (hazard ratio: 0,63; 95% CI; 0,42-0,95; P=.036). Completely resected patients with stage pIIIA-N2 NSCLC receiving adjuvant treatment reached higher survival rates than those who did not. Maximum benefit was achieved by the subgroup of patients under 70 years of age with squamous cell carcinoma. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    Full Text Available Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare. Due to the mostly asymptomatic behavior and the historical confusion regarding histology, an exact prevalence is not known. We present here a case report of a retroperitoneal bronchogenic cyst. A literature review was performed for cases of retroperitoneal bronchogenic cysts written in English. Anatomopathological criteria for inclusion were pseudo stratified, ciliated, columnar epithelium together with the presence of at least one of the following: cartilage, smooth muscle or seromucous glands. In addition, the embryology, pathogenesis, radiological, clinical and suggested treatment modalities are reviewed. We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a non-functioning left adrenal mass. Our review of literature revealed only 62 potential cases of retroperitoneal bronchogenic cysts. After applying the strict anatomopathological criteria, only 30 cases of true retroperitoneal bronchogenic cysts could be identified. Retroperitoneal location of a bronchogenic cyst is rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Only histology can confirm definitive diagnosis. Surgery remains the recommended treatment of choice.

    Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare. Due to the mostly asymptomatic behavior and the historical confusion regarding histology, an exact prevalence is not known. We present here a case report of a retroperitoneal bronchogenic cyst. A literature review was performed for cases of retroperitoneal bronchogenic cysts written in English. Anatomopathological criteria for inclusion were pseudo stratified, ciliated, columnar epithelium together with the presence of at least one of the following: cartilage, smooth muscle or seromucous glands. In addition, the embryology, pathogenesis, radiological, clinical and suggested treatment modalities are reviewed. We report the surgical excision of a retroperitoneal bronchogenic cyst that presented as a non-functioning left adrenal mass. Our review of literature revealed only 62 potential cases of retroperitoneal bronchogenic cysts. After applying the strict anatomopathological criteria, only 30 cases of true retroperitoneal bronchogenic cysts could be identified. Retroperitoneal location of a bronchogenic cyst is rare. Despite the rarity of this pathologic entity, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions. Only histology can confirm definitive diagnosis. Surgery remains the recommended treatment of choice. PMID:22532911

    Full Text Available Apesar dos avanços no tratamento, há pouca melhora na sobrevida dos pacientes com câncer do pulmão. Atualmente, é importante o conhecimento dos fatores que intervêm na sobrevida. Objetivos: Verificar possíveis diferenças de fatores prognósticos em duas populações de pacientes com câncer de pulmão, uma com pequena sobrevida (menos de seis meses e outra com maior sobrevida (acima de 24 meses. Métodos: De 1997 a 1999 foram estudados 52 pacientes com diagnóstico histopatológico de carcinoma homogênico, sendo colhidos dados demográficos, clínicos, paramétricos, hábitos tabágicos, índice de Karnofsky, estadiamento da doença e dosagem laboratorial de desidrogenase lática, fosfatase alcalina, antígeno carcinoembrionário e cálcio. Resultados: 29 pacientes tiveram sobrevida menor do que seis meses e 23, superior a 24 meses. Os três fatores mais importantes que influenciaram o tempo curto de sobrevida foram baixo índice de Karnofsky inicial, redução do apetite e alto nível sérico de DHL. Conclusão: Os três componentes do prognóstico são o estado físico atual, o estado físico prévio e o estado atual da doença.Despite the improvements seen in the treatment of lung cancer, little has improved in the survival of these patients, and a great importance is attributed to the factors that have a role to play in such survival. Purpose: To check for possible prognostic factor differences in two populations of lung cancer patients, one of them with short survival (less than six months, and the other with longer survival (more than 24 months. Methods: From 1997 to 1999, 52 patients with histopathologic diagnosis of homogenous carcinoma were studied, and demographics, clinical parameters, smoking pattern, Karnofsky's index, disease staging, and laboratory dosing of lactic dehydrogenase, alkaline phosphatase, carcinoembryonic antigen, and calcium data were surveyed. Results: 29 patients had less than six month survival, and 23

    Full Text Available Diagnosis of bronchogenic cysts is possible with computed tomography, but half of all cases present as soft tissue densities. Two such cases are highlighted where asymptomatic bronchogenic cysts that presented as soft tissue masses were evaluated by endobronchial ultrasound (EBUS. After studying the ultrasound image characteristics, the diagnosis was confirmed using EBUS-guided transbronchial needle aspiration (EBUS-TBNA. The first case had ultrasound findings of an anechoic collection, and the aspirate was serous with negative microbiologic cultures. The second was an echogenic collection within a hyperechoic wall. Needle aspirate was purulent and cultured Haemophilus influenza. The diagnosis of a bronchogenic cyst complicated by infection was made, and the lesion was surgically resected. This potential for EBUS in the diagnosis of bronchogenic cysts and in identifying complications such as infection should be considered in the management of such cases.

    This case report presents an intrapulmonary bronchogenic cyst exhibiting a unique shape. The patient was a 19-year-old man who had been diagnosed with a posterior mediastinal tumor by computed tomography and magnetic resonance imaging, 2 years previously. The imaging revealed that the tumor was located on the left side of the posterior mediastinum and was 45 × 25 mm in size. As the size and shape of the tumor did not change in the 2 years after its detection, surgical extraction was planned. Preoperative diagnosis was, firstly, a neurogenic tumor originating in the posterior mediastinum.Surgical findings revealed that the tumor formed a bridge between the visceral pleura of the left lower lobe and the chest wall, and most of the tumor was located in the thoracic cavity. Pathological diagnosis was intrapulmonary bronchogenic cyst. An intrapulmonary bronchogenic cyst with a unique shape, as observed in this case, is very rare.Although preoperative imaging could predict the tumor size, it could not confirm where the tumor originated. Surgical resection of this type of tumor, which is diagnosed preoperatively as a posterior mediastinal tumor, is a superior strategy for precise diagnosis and treatment.

    Full Text Available Bronchogenic cysts arise from abnormal buds from the primitive esophagus and tracheobronchial tree, which do not extend to the site where alveolar differentiation occurs. Bronchogenic cysts are typically unilocular mucus field lesions arising from posterior membranous wall of the air way. The prenatal diagnosis usually is realized by two-dimensional ultrasound showing the large unilocular cystic image in the chest fetus. The prenatal percutaneous aspiration can reduce the risk of heart compression and permit better respiratory conditions to newborn. We present a case of a primiparous pregnant 23 year-old-woman prenatal ultrasound showed a large unilocular cyst in the left hemithorax with compression of the normal left lung tissue and contralateral mediastinal shift. This cyst was percutaneously aspirated without subsequent reaccumulation of fluid. The newborn did not have respiratory distress and the computed tomography scan confirmed the finding of a fluid-filled cyst in the left chest. The chest X-ray showed the displacement of the heart and the mediastinum from the left to the right. The prenatal diagnosis of bronchogenic cyst is very important to assess the degree of the compression of the normal lung and the mediastinum shift. Furthermore, the prenatal diagnosis permits planning delivery in the tertiary hospital with multidisciplinary team because of the risk of respiratory distress.

    Full Text Available Abstract Introduction Bronchogenic cysts are developmental anomalies of the primitive foregut which mostly occur in the lung. Gastric bronchogenic cysts are extremely rare; few cases have been reported in the literature and the diagnosis was often made following surgical resection. Case presentation A 40-year-old North African man was admitted to our hospital with a gastric submucosal mass. An endoscopic ultrasound revealed a unilocular cystic mass located in the muscular layer. Its content was echogenic suggestive of mucus. Magnetic resonance imaging confirmed the liquid nature of the cyst and showed a high ratio of proteins. Based on these observations, the diagnosis of bronchogenic cyst was confirmed. An endoscopic monitoring was decided rather than surgery because of the small size of the cyst and the absence of symptoms. Conclusion Although gastric bronchogenic cysts are rare, they should be well known and considered in all differential diagnoses of gastric tumors. We report a new case of gastric bronchogenic cyst and highlight the contribution of morphological tests that currently allow a non-invasive diagnosis.

  18. Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

    Directory of Open Access Journals (Sweden)

    Avradip Santra

    2016-07-01

    Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

    Full Text Available Intraspinal bronchogenic cyst (SBC is a rare but important cause of spinal cord compression, commonly seen in the cervicothoracic spine. We report a case of a 43-year-old male, presenting with complaints of neck pain, radiating to right shoulder, with numbness of right hand and fingers. Magnetic resonance imaging of the cervical spine revealed an intradural extramedullary, ventral cystic lesion extending from C2 to C4 vertebral levels. Complete surgical excision was performed, and the patient had a complete relief of symptoms postoperatively. Only 11 cases of SBCs have been reported in literature. We discuss the peculiar location of this lesion, possible embryological reasons and the overall surgical outcome of SBC.

    2017-01-01

    Abstract Rationale: Retroperitoneal bronchogenic cysts without specific clinical manifestations are extremely rare and difficult to diagnose preoperatively and are easily misdiagnosed as left adrenal or pancreatic tumors. Patient concerns: A 48-year-old woman with the chief complaint of obscure epigastric pain for 1 month and with no other gastrointestinal symptoms and no significant medical history. The patient had signed informed consent for publication of this case report. Diagnosis: The serum level of carbohydrate antigen 19-9 (CA 19-9) in the patient was >1200 U/mL, which far exceeded the normal level of tumor. However, endoscopic ultrasound (EUS) showed that the adrenal gland had an intact capsule and that the mass originated in the retroperitoneal space and did not involve the paranephros. Interventions: Surgical resection was performed on the patient. Outcomes: Histopathological examination demonstrated that the mass was a retroperitoneal bronchogenic cyst. At the 2-month postoperative follow-up, the level of CA 19-9 had returned to normal. Lessons: EUS appears to be superior to CT because it clearly delineated the mass from the surrounding structures of the retroperitoneal region. EUS-fine needle aspiration can be used for diagnosis or determining whether the mass is malignant or benign. To the best of our knowledge, retroperitoneal bronchogenic cysts with significantly elevated serum CA 19-9 have not been reported. Measurement of serum CA 19-9 may be helpful in the diagnosis of retroperitoneal bronchogenic cysts. However, this was a rare case, and the mechanism behind CA 19-9 elevation is not clear and needs further investigation. PMID:28767594

    A follow-up 18F-fluorodeoxyglucose ({sup 18}F-FDG) PET/CT scan of a 57-year-old asymptomatic male who had undergone total thyroidectomy for thyroid cancer revealed a 5.0 x 4.0-cm, well-defined, ovoid-shaped mass around the left adrenal gland without definite FDG uptake. On the adrenal CT scan, the left paraadrenal tumor showed high attenuation on the precontrast scan without enhancement. The average Hounsfield unit (HU) was 58.1 on the precontrast scan and 58.4 on the postcontrast scan. The patient underwent laparoscopic adrenalectomy for resection of the left paraadrenal tumor. The final histopathologic examination revealed a bronchogenic cyst. Although retroperitoneal bronchogenic cysts are rare, they should be considered in the differential diagnosis of retroperitoneal cystic tumors. The preoperative diagnosis is difficult, but a contrast-enhanced CT scan or {sup 18}F-FDG PET/CT scan may be useful for differentiating hyperattenuated cysts from other soft tissue masses.

    Full Text Available Background and objective It is well-known that angiopoietin-2 (Ang-2 plays an important role in the formation of the blood vascular system. Angiopoietin is involved in many diseases about angiogenesis such as tumor, so may have great prospects for the treatment of these diseases. The aim of this study is to evaluate the influence of inhibiting Ang-2 via adeno-associated virus induced RNA interference (RNAi on the biological characteristics of bronchogenic adenocarcinoma. Methods AAV-Ang-2shRNA driven by H1 promoter was constructed to transfect A549 cell line. Normal and AAV-Null cell line were utilized in the control groups. The influence of RNAi on Ang-2 expression as well as the growth rate, tumorigenic efficiency, proliferation rate, apoptosis, and microvessel density of A549 cell line were analyzed. Results In vitro experiment indicated that the Ang-2 expression level (P<0.001 and growth rate (P<0.001 of A549 cell line 48 h transfected with AAV-Ang-2shRNA were significantly lower than those in the normal and AAV-Null cell lines. Cell cycle analysis showed the proliferation index (PI of normal, AAV-Null, and AAV-Ang-2shRNA transfected A549 cell line were 0.51±0.43, 0.48±0.29, and 0.26±0.31, respectively, which indicated the PI of AAV-Ang-2shRNA transfected cell line was significantly lower, compared with the normal and AAV-Null cell lines. In vivo experiment exhibited that AAV-Ang-2shRNA transfected cell line possessed a lower mass and volumn of tumor relative to two control groups. In addition, the apoptosis index (AI of AAV-Ang-2shRNA transfected, normal, and AAV-Null cell lines were (5.98±3.11%, (7.51±4.42% and (17.06±7.43% respectively, which manifested that AAV-Ang-2shRNA transfected cell line possessed a higher AI (P=0.005, P=0.007. A lower percentage of PCNA-positive cell was observed in AAV-Ang-2shRNA transfected cell line (92.75±9.7% as well, compared with the normal (85.8±11.8% and AAV-Null (69.8±16.5% cell lines

    Full Text Available Bronchogenic cyst, a benign congenital cystic lesion of the lung, is a rare cause of respiratory distress in children comprising 7.5% of all mediastinal masses. A thorough preoperative evaluation is crucial to plan for definitive intra- and post-operative management. All patients should be thoroughly evaluated for the presence of compression, deviation or distortion of airways and great veins. The easiest means of providing one lung ventilation in pediatrics is to intubate the main stem bronchus of the nonoperated lung. Other options available for pediatric one lung ventilation are single lumen endobronchial tubes, micro cuff tubes, Marraro bilumen tubes, and bronchial blockers. We hereby present a case report of a 2-month-old infant posted for excision of bronchogenic cyst along with a review of literature.

    Bronchogenic cysts are congenital anomalies resulting from abnormal budding of the tracheobronchial tree. Generally are asymptomatic in adults, unless infected or compressing neighbouring structures, and usually are discovered on routine examinations. Controversially, more recent studies report a high incidence of symptoms in adults, but worthlessed in routine examinations. The authors report 15 patients seen at the Pneumology and Thoracic Surgery and Image Diagnosis Departments of the Heliopolis Hospital, Sao Paulo State, between 1977 and 1996 (20 years), which undergone surgical excision for pulmonary (n=11) and mediastinal (n=4) bronchogenic cysts. There were 11 men and 4 women, with ages between 17 and 74 years. Sixty-six percent were symptomatic at the time of diagnosis. All the patients were investigated with chest radiographs, and 4 of them with computed tomography. All cysts localized in the mediastinum were excised locally, while the intrapulmonary ones needed pulmonectomy in a variable degree. Through a literature and a casuistic analysis the authors discuss the main etiology, clinical, surgical and radiological features of bronchogenic cysts. (author) 11 refs., 6 figs.

    2017-01-01

    Follicular carcinoma of thyroid is the second most common type of carcinoma of thyroid, and it may metastasize to bone, lung, brain, and skin. However, the initial presentation of follicular carcinoma of the thyroid as a large intrathoracic mass without any symptoms of thyroid gland enlargement and dysfunction is very rare. We hereby report a case of a 50-year-old male who presented with chief complaints of chest and low back pain. Preliminary evaluation led to the provisional diagnosis of left-sided intrathoracic mass with vertebral metastasis which was suspected to be a case of bronchogenic carcinoma with distant metastasis. Surprisingly, transthoracic biopsy and histopathology revealed metastasis from follicular carcinoma of thyroid. This prompted us for a retrograde evaluation for a primary thyroid malignancy for which an ultrasound and contrast enhanced computed tomography (CECT) of the neck was done which confirmed the presence of a solitary thyroid nodule. Ultrasonography-guided fine-needle aspiration cytology of the nodule revealed follicular carcinoma of thyroid. Histopathological evaluation subsequent to total thyroidectomy revealed follicular carcinoma thyroid, further confirming the diagnosis. The patient was then referred to Department of Nuclear Medicine and Radiotherapy for radionuclide ablation and chemotherapy. We chose to report this case because of its rare presentation as a large intrathoracic mass and the retrograde diagnosis of follicular carcinoma of thyroid. To the best of our knowledge, this is the first report of such a rare case.

    Full Text Available Introduction. There has been limited information reported on the use of hepatic arterial therapy in liver dominant hepatic metastases arising from lung cancer. The aim of this study was to evaluate the safety and efficacy of hepatic arterial therapy in the treatment of liver dominant hepatic metastases arising from lung cancer. Methods. Thirteen patients underwent a total of 30 treatment sessions with Drug-Eluting Beads. Eight of the thirteen received only doxorubicin DEB (17 of the total treatments, and four patients received Irinotecan DEB (7 of the total treatments. Results. The planned preprocedural dosage was a median of 75 mg (range 19–200, with total hepatic dose exposure being a median of 150 mg (range 0–458, with a technical success rate of 97% in all 29 treatments. There were 4 adverse events related to treatment, but no evidence of hepatic insufficiency. Overall 6-month and 12-month response rates were 50%. After a median followup of 24 months, the median overall survival in this cohort was 14 months (range 7–48 months. Conclusion. Drug-eluting beads loaded with doxorubicin (DEBDOX or irinotecan (DEBIRI can be safely and effectively used in treatment of patients with liver predominant metastatic disease from lung cancer.

    A prospective study, including 112 patients, designed to estimate the sensitivity and specificity of slide-touch and pleural lavage cytology for diagnosis of pleural micrometastases in operable non-small cell lung cancer (NSCLC). Histopathologically, excised tumors showed P0 in 22 patients (19%), P1 in 44 patients (39%), P2 in 32 patients (29%), P3 in 14 patients (13%). Cytological examination of the three slide-touch prints from visceral pleura overlying the tumor (slide 1), parietal pleura facing tumor (slide 2), parietal pleura in paravertebral gutter (slide 3) resulted in: slide 1: positive in 60% (66/112) [this included p0 (2 out of 22), p1 (22 out of 44), p2 (32 out of 32) and p3 (10 out of 14)], slide 2: positive in 13% (14/112); all of them had P3, and slide 3 positive in 8% (9/112). Total positive slides 62% (70/112). Pleural lavage: positive in 19% (22/112), all of them were detected with slide 1 and/or slide 2. During follow-up, patients with negative slides had no local or distant metastases (truly negative), six recurrences among those with positive slide 1, including four with positive lavage. Thus, slide touch print is more sensitive than lavage cytology, both of prognostic significance. Slide 1 is a highly sensitive detector of visceral pleural micrometastases; slide 2 is a more sensitive detector of parietal pleural invasion; slide 3 is the least.

    To verify the accuracy of the absorbed doses D calculated by a TPS Cadplan for a bronchogenic treatment (in an Alderson-Rando phantom) are chosen ten points with the following D's and localizations. Point 1, posterior position on the left edge with 136.4 Gy. Points: 2, 3 and 4 in the left lung with 104.9, 104.3 and 105.8 Gy, respectively; points 5 and 6 at the mediastinum with 192.4 and 173.5 Gy; points 7, 8 and 9 in the right lung with 105.8, 104.2 and 104.7 Gy, and 10 at posterior position on right edge with 143.7 Gy. IAEA type capsules with TLD 100 powder are placed, planned and irradiated. The evaluation of the absorbed dose is carried out a curve of calibration for the LiF response (nC) {sup vs} {sup DW}, to several cavity theories. The traceability for the DW is obtained with a secondary standard calibrated at the NRC (Canada). The dosimetric properties for the materials considered are determined from the Hounsfield numbers reported by the TPS. The stopping power ratios are calculated for nominal spectrum to 6 MV photons. The percent variations among the planned and determined D in all the cases they are < ± 3%.

    Small cell carcinoma (SmCC) is a distinct clinicopathological entity first described in the lung. It represents approximately 15% of all bronchogenic carcinoma. Extrapulmonary small cell carcinoma (EPSmCC) morphologically indistinguishable from small cell lung cancer (SCLC) was first reported in 1930. Since its first description, EPSmCC has been reported in virtually all anatomical sites, including: gynecologic organs (ovary and cervix); genitourinary organs (urinary bladder and prostate); the gastrointestinal tract (esophagus); skin (Merkel cell carcinoma) and head and neck region. Regardless of the anatomic sites, all SmCCs have similar, if not identical, histo-pathology features and immunohistochemical profile. SmCC is one of the most aggressive malignancies. The molecular mechanisms underlying its development and progression remain poorly understood. Herein, we reviewed the literature in SmCC in respect to its site of occurrence, clinical features, immunohistochemical characteristics. SmCCs have heterogeneous molecular mutations. Dinstinct genetic alterations associated with SmCC from different body sites were reviewed. Some genetic alterations such as RB1, TP53 are commonly seen in different origins of SmCC. Other genes with site specificity were also summarized, such as bladder SmCC with TERT promoter mutations; prostate SmCC with ERG translocations; ovarian SmCC with SMARCA4 mutations; Merkel cell carcinoma (skin) and cervical SmCC with Merkel cell polyomavirus (MCV or MCPyV) and human papillomavirus (HPV). Further studies are needed to employ a genetically oriented approach for the diagnosis and therapy of SmCC.

    Twenty-one patients with stage III M/sub 0/ non-oat cell bronchogenic carcinoma confined to the thorax were randomized to receive either intrapleural BCG (10/sup 7/ cfu, Tice strain) or intrapleural saline 3 weeks prior to beginning combined irradiation and chemotherapy. Radiation to the primary tumor and regional nodes was given at a dose of 3,000 rad in ten sessions and was followed in 7-14 days by CAMP chemotherapy (cyclophosphamide, adriamycin, methotrexate, and procarbazine) for a planned duration of 6 months. Isoniazid, 300 mg/day, was given to all patients for 3 months starting 1 week after intrapleural therapy. There were no significant differences in pretreatment prognostic factors or in response to radiation therapy. The patients receiving intrapleural BCG in addition to radiation and chemotherapy had a median survival of 18 weeks, significantly shorter than that for the patients receiving intrapleural saline (54 weeks, P=0.017).

    Full Text Available Background. Carcinoma of the gallbladder is a tumour with a dismal prognosis and 5-years overall survival rate less than 5%. Among the tumours of the gastrointestinal tract it is fifth in the row and its incidence is approximately 1.2/105. Tumour occurs more often (2–6 times in women and in people over 50 years old (90%. According to the Slovenian Registry of Cancer for year 1998 the incidence of gallbladder carcinoma was 2.7/105 and it occurred 4 times more often among women. The most important risk factors for development of gallbladder carcinoma are: bile stones, chronic inflammation and polyps of the gallbladder. Carcinoma of the gallbladder develops in only 2–3% of the patients with bile stones. When discovered, carcinoma has already invaded the liver in 60%, regional lymph nodes in 45% and the other surrounding organs in 40%. Carcinoma is at time of diagnosis already disseminated in distant organs in 20%. Only in 10% of the patients it is confined to the gallbladder wall. Before the routine use of the ultrasound, computed tomography and tumour markers the disease was discovered preoperatively in 10% versus 90% today. Diagnostic percutaneous biopsy is not recommended. TNM classification and staging of the disease is important for the decision of the modality of treatment.Conclusions. For TNM stage I gallbladder carcinoma, simple cholecystectomy is sufficient. When stage II-IVa is discovered, »en block« resection of gallbladder, liver segments 4b and 5, common bile duct and thorough lymphadenectomy is recommended. Regional radiotherapy and intraarterial chemotherapy with Mitomycin-C are showing promising results. Longterm outcome in patients with gallbladder carcinoma is improving but it is still disappointing.

    Full Text Available Abstract Nasopharyngeal carcinoma (NPC is a tumor arising from the epithelial cells that cover the surface and line the nasopharynx. The annual incidence of NPC in the UK is 0.3 per million at age 0–14 years, and 1 to 2 per million at age 15–19 years. Incidence is higher in the Chinese and Tunisian populations. Although rare, NPC accounts for about one third of childhood nasopharyngeal neoplasms. Three subtypes of NPC are recognized in the World Health Organization (WHO classification: 1 squamous cell carcinoma, typically found in the older adult population; 2 non-keratinizing carcinoma; 3 undifferentiated carcinoma. The tumor can extend within or out of the nasopharynx to the other lateral wall and/or posterosuperiorly to the base of the skull or the palate, nasal cavity or oropharynx. It then typically metastases to cervical lymph nodes. Cervical lymphadenopathy is the initial presentation in many patients, and the diagnosis of NPC is often made by lymph node biopsy. Symptoms related to the primary tumor include trismus, pain, otitis media, nasal regurgitation due to paresis of the soft palate, hearing loss and cranial nerve palsies. Larger growths may produce nasal obstruction or bleeding and a "nasal twang". Etiological factors include Epstein-Barr virus (EBV, genetic susceptibility and consumption of food with possible carcinogens – volatile nitrosamines. The recommended treatment schedule consists of three courses of neoadjuvant chemotherapy, irradiation, and adjuvant interferon (IFN-beta therapy.

    The distinction between ocular sebaceous carcinoma, poorly differentiated ocular squamous cell carcinoma and ocular basal cell carcinoma can be challenging. An appropriate immunohistochemical panel may help to differentiate these lesions. To determine the distribution and use of several immunostains in these specimens, formalin-fixed, paraffin-embedded tissue from several of each was studied using an immunohistochemical technique. Positive staining for cytokeratin (CK)7 was seen in 100% of sebaceous carcinomas, 77.8% of basal cell carcinomas and 67.7% of squamous cell carcinomas. One hundred percent of sebaceous and basal cell carcinomas were positive for cytokeratin CAM 5.2, while only 83.3% of squamous cell carcinomas were positive. Using epithelial membrane antigen (EMA), 100% of squamous cell carcinomas and 80% of sebaceous carcinomas were positive, while basal cell carcinomas were uniformly negative. One hundred percent of basal cell carcinomas and 80% of sebaceous carcinomas were positive for Ber-EP4, while all squamous cell carcinomas were negative. Finally, 77.8%, 20% and 16.7% of basal cell carcinomas, sebaceous carcinomas and squamous cell carcinomas showed immunoreactivity for the androgen receptor. An EMA positive, Ber-EP4 positive immunophenotype supports sebaceous carcinoma, EMA positive, Ber-EP4 negative result supports squamous cell carcinoma and an EMA negative, Ber-EP4 positive result supports basal cell carcinoma.

    Full Text Available Small cell neuroendocrine carcinoma (SNEC is a rare form of malignancy. It mainly presents as bronchogenic neoplasm, and the extrapulmonary form accounts for only 0.1% to 0.4% of all cancers. These extrapulmonary tumors have been described most frequently in the urinary bladder, prostate, esophagus, stomach, colon and rectum, gall bladder, head and neck, cervix, and skin. Primary SNEC of the sinonasal tract is extremely rare with only less than 100 cases reported in the literature. Because of extreme rarity and aggressiveness of the tumor, the management for this entity varies considerably mandating multimodality approach. In this paper, we report a patient presented with left-sided facial swelling, and the histopathologic examination confirmed primary SNEC of left sinonasal tract. The tumor involved multiple paranasal sinuses with invasion into the left orbit and left infratemporal fossa and metastasized to cervical lymph nodes and bone. The patient encountered devastating outcome in spite of optimal medical management and treatment with palliative chemotherapy highlighting the necessity for further research of primary SNEC of head and neck.

    1997-08-01

    Oesophageal carcinoma is an aggressive malignant tumour, and in Western countries accounts for only about 3 per cent of all malignancies. In other countries, such as China, this rate can be as high as 25 per cent, and as a result, is responsible for many deaths from malignancy. Despite this fairly low presentation rate in Westernised countries, the survival rate for sufferers beyond five years is dismal. This is also reflected in other parts of the world. Even with complex surgical techniques and Radiation Therapy, the survival rate has not improved markedly with these advanced techniques. This article gives a broad overview of Oesophageal Carcinoma, with a Westmead influence in reference to diagnosis, treatment and prognosis. The assessment of the tumour is done in a number of different ways. Barium Swallow is useful in assessing the length of the tumour. Endoscopy is also used to assess tumour length, this method being more sensitive than Barium Swallow. A CT of the Chest, Abdomen and Pelvis is performed to assess local spread, distant metastases and is also used for planning. The CT may be done as an Angio CT. Other methods of assessment used in a lesser extent, due to the technology being new, or from lack of experienced operators is MRI, endoscopic ultrasound and laparoscopic ultrasound. There are a number of different forms of treatment that may be considered, dependant upon the condition of the patient, and whether or not the tumour is considered `curable`. At Westmead Hospital, the considerations for treatment are: radiation therapy (as palliative therapy), surgery, combined radiation and chemotherapy and palliative therapy. 1 refs., 9 figs.

    2016-09-01

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that shares the same histologic appearance and ETV6 gene (12p13) rearrangement as secretory carcinoma of the breast. Prior to its recognition, MASC cases were commonly labeled acinic cell carcinoma and adenocarcinoma, not otherwise specified. Despite distinctive histologic features, MASC may be difficult to distinguish from other salivary gland tumors, in particular zymogen-poor acinic cell carcinoma and low-grade salivary duct carcinoma. Although characteristic morphologic and immunohistochemical features form the basis of a diagnosis of MASC, the presence of an ETV6-NTRK3 gene fusion is confirmatory. Given its recent recognition the true prognostic import of MASC is not yet clearly defined.

    Full Text Available Renal cell carcinoma is the most common neoplasm of the kidney comprised of different histological variants. Chromophobe renal cell carcinoma (ChRCC is a rare subtype of renal cell carcinoma (RCC mainly diagnosed in the sixth decade of life. It is important to identify this entity because it has significantly better prognosis than the clear cell (conventional and papillary renal cell carcinomas. The chromophobe renal cell carcinoma should be differentiated from oncocytoma and clear cell carcinoma. We report a case of a 70 year-old male who presented with a six month history of hematuria, left sided flank pain and a palpable non-tender lump in the left lumbar region. On radiology, the possibility of a left renal neoplasm was raised. A left radical nephrectomy was done and histopathological diagnosis of Type 2 (mixed chromophobe renal cell carcinoma was given. We present this case owing to its relative rarity of incidence, difficulties encountered and differential diagnoses to be considered during diagnosis as the prognosis and management protocols differ with different variants.

    The majority of hepatocellular carcinoma occurs over pre-existing chronic liver diseases that share cirrhosis as an endpoint. In the last decade, a strong association between lifestyle and hepatocellular carcinoma has become evident. Abundance of energy-rich food and sedentary lifestyles have caused metabolic conditions such as obesity and diabetes mellitus to become global epidemics. Obesity and diabetes mellitus are both tightly linked to non-alcoholic fatty liver disease and also increase hepatocellular carcinoma risk independent of cirrhosis. Emerging data suggest that physical activity not only counteracts obesity, diabetes mellitus and non-alcoholic fatty liver disease, but also reduces cancer risk. Physical activity exerts significant anticancer effects in the absence of metabolic disorders. Here, we present a systematic review on lifestyles and hepatocellular carcinoma.

    Pulmonary sarcomatoid carcinomas are a rare group of tumors accounting for about one percent of non-small cell lung carcinoma (NSCLC). In 2015, the World Health Organization classification united under this name all the carcinomas with sarcomatous-like component with spindle cell or giant cell appearance, or associated with a sarcomatous component sometimes heterologous. There are five subtypes: pleomorphic carcinoma, spindle cell carcinoma, giant cell carcinoma, carcinosarcoma and pulmonary blastoma. Clinical characteristics are not specific from the other subtypes of NSCLC. Epithelial to mesenchymal transition pathway may play a key role. Patients, usually tobacco smokers, are frequently symptomatic. Tumors are voluminous more often peripherical than central, with strong fixation on FDG TEP CT. Distant metastases are frequent with atypical visceral locations. These tumors have poorer prognosis than the other NSCLC subtypes because of great aggressivity, and frequent chemoresistance. Here we present pathological description and a review of literature with molecular features in order to better describe these tumors and perhaps introduce new therapeutics. Copyright © 2016.

  20. Early onset sebaceous carcinoma

    2011-09-01

    Full Text Available Abstract Background Ocular sebaceous carcinoma can masquerade as benign lesions resulting in delay of diagnosis. Early recognition is even more difficult in young patients where the disease rarely occurs. Here, we provide a clinicopathological correlation of ocular sebaceous carcinoma in a young individual lacking history of hereditary cancer or immunosuppression. Findings A detailed histopathological study including p53 DNA sequencing was performed on an aggressive sebaceous carcinoma presenting in a healthy 32 year-old Caucasian woman. She had no history of retinoblastoma, evidence for a hereditary cancer syndrome, or radiation therapy. However, she potentially was at risk for excessive UV light exposure. A detailed review of the literature is also provided. A moderately well differentiated sebaceous carcinoma was established histopathologically arising from the meibomian gland of the upper eyelid. In most areas, the cytoplasm contained small but distinct Oil-red-O positive vacuoles. Direct sequencing of p53 identified a G:C→A:T mutation at a dipyrimidine site. The mutation results in substitution of arginine for the highly conserved glycine at residue 199 located at the p53 dimer-dimer interface. Energy minimization structural modeling predicts that G199R will neutralize negative charges contributed by nearby inter- and intramonomeric glutamate residues. Discussion This study points to the importance of recognizing that sebaceous carcinoma can occur in young patients with no evidence for hereditary cancer risk or radiation therapy. The G199R substitution is anticipated to alter the stability of the p53 tetrameric complex. The role of UV light in the etiology of sebaceous carcinoma deserves further study. Our findings, taken together with those of others, suggest that different environmental factors could lead to the development of sebaceous carcinoma in different patients.

    The objective was to perform a systematic review of literature concerning epidemiology, clinical and biological data, prognosis and therapy of sarcomatoid renal cell carcinomas. Data on sarcomatoid renal cell carcinomas have been sought by querying the server Medline with MeSH terms following or combination of them: "renal carcinoma", "renal cell carcinoma," "renal cancer", "sarcomatoid" "sarcomatoid transformation" and "sarcomatoid differentiation." The articles obtained were selected according to their methodology, the language in English or French, the relevance and the date of publication. Twenty papers were selected. According to the literature, a sarcomatoid contingent can be observed in all subtypes of renal cell carcinomas, with a frequency of 1 to 15% of cases. The median age at diagnosis was 60 years with a majority of symptomatic patients (90%), mainly with abdominal pain and hematuria. These tumors were often found in patients with locally advanced or metastatic (45-77%). The imaging was not specific for the diagnosis and biopsy had a low sensitivity for identifying a sarcomatoid contingent. The treatment was based on a combination of maximal surgical resection whenever possible and systemic therapy for metastastic disease. Pathological data often showed large tumors, Furhman 4 grades, combined biphasic carcinomatous contingent (clear cell carcinoma in most cases) and sarcomatoid. Genetically, there was no specific abnormality but a complex association of chromosomal additions and deletions. The prognosis was pejorative with a specific median survival of 5 to 19 months without any impact of the sarcomatoid contingent rate. Sarcomatoid renal cell carcinoma is a form not to ignore despite its rarity. Mainly symptomatic and discovered at an advanced stage, it has a poor prognosis, requiring multidisciplinary management quickly and correctly. Copyright © 2013 Elsevier Masson SAS.

    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.

    Full Text Available Abstract Background Merkel cell carcinoma (MCC is an unusual primary neuroendocrine carcinoma of the skin. MCC is a fatal disease, and patients have a poor chance of survival. Moreover, MCC lacks distinguishing clinical features, and thus by the time the diagnosis is made, the tumour usually have metastasized. MCC mainly affects sun-exposed areas of elderly persons. Half of the tumours are located in the head and neck region. Methods MCC was first described in 1972. Since then, most of the cases reported, have been in small series of patients. Most of the reports concern single cases or epidemiological studies. The present study reviews the world literature on MCC. The purpose of this article is to shed light on this unknown neuroendocrine carcinoma and provide the latest information on prognostic markers and treatment options. Results The epidemiological studies have revealed that large tumour size, male sex, truncal site, nodal/distant disease at presentation, and duration of disease before presentation, are poor prognostic factors. The recommended initial treatment is extensive local excision. Adjuvant radiation therapy has recently been shown to improve survival. Thus far, no chemotherapy protocol have achieved the same objective. Conclusion Although rare, the fatality of this malignancy makes is important to understand the etiology and pathophysiology. During the last few years, the research on MCC has produced prognostic markers, which can be translated into clinical patient care.

    2018-01-25

    The review puts new information on geno- and phenotype of salivary duct carcinoma (SDC) in the perspective of the updated 2017 WHO classification. The proportion of SDC is increasing. This may be because of a true rise in incidence, but certainly to better diagnostic tests and changed WHO definitions. In this light, a substantial proportion of carcinoma expleomorphic adenoma is now attributed to the category of SDC. 'Low-grade SDC' and 'SDC in-situ' of the former WHO classification, are now named low-grade and high-grade intraductal carcinoma (IDC), respectively. Recent series quantify biologic aggressiveness: perineural growth, vascular invasion, and extracapsular extension in lymph node metastasis are each observed in two out of three patients with SDC. Most patients die within 3 years, but once 5-year disease-free survival is reached, further disease activity is exceptional. The typical molecular biological profile with high human epidermal growth factor receptor 2 and androgen receptor expression is increasingly successfully exploited in clinical trials for advanced SDC. The aggressive SDC is increasingly diagnosed. Despite intensive combined surgery and radiation therapy, many patients recur, for whom new bullets, targeting the molecular biological mechanisms, are the subject of ongoing clinical trials.

    Piura, Ettie; Piura, Benjamin

    2012-01-01

    This paper will focus on knowledge related to brain metastases from endometrial carcinoma. To date, 115 cases were documented in the literature with an incidence of 0.6% among endometrial carcinoma patients. The endometrial carcinoma was usually an advanced-stage and high-grade tumor. In most patients (~90%), brain metastasis was detected after diagnosis of endometrial carcinoma with a median interval from diagnosis of endometrial carcinoma to diagnosis of brain metastases of 17 months. Brain metastasis from endometrial carcinoma was either an isolated disease limited to the brain only (~50%) or part of a disseminated disease involving also other parts of the body (~50%). Most often, brain metastasis from endometrial carcinoma affected the cerebrum (~75%) and was solitary (~60%). The median survival after diagnosis of brain metastases from endometrial carcinoma was 5 months; however, a significantly better survival was achieved with multimodal therapy including surgical resection or stereotactic radiosurgery followed by whole brain radiotherapy (WBRT) and/or chemotherapy compared to WBRT alone. It is suggested that brain imaging studies should be considered in the routine follow up of patients with endometrial carcinoma and that the search for a primary source in females with brain metastases of unknown primary should include endometrial biopsy.

    2012-02-01

    Thyroid carcinoma is the most commonly diagnosed endocrine malignancy. Its incidence is currently rising worldwide. The discovery of genetic mutations associated with the development of thyroid cancer, such as BRAF and RET, has lead to the development of new drugs which target the pathways which they influence. Despite recent advances, the prognosis of anaplastic thyroid carcinoma is still unfavourable. In this review we look at emerging novel therapies for the treatment of well-differentiated and medullary thyroid carcinoma, and advances and future directions in the management of anaplastic thyroid carcinoma.

    A 16-year-old girl presented to our unit with crampy abdominal pain, change in bowel habit, a subjective impression of weight loss and a single episode of haematochezia. She was found to have a rectosigmoid adenocarcinoma and proceeded to laparoscopic anterior resection, whereupon peritoneal metastases were discovered. She received chemotherapy and is alive and well ten month later with no radiological evidence of disease. Colorectal carcinoma is rare in the paediatric population but is increasing in incidence. Early diagnosis is critical to enable optimal outcomes.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    Rectal carcinoma is a rare, but well documented late complication of pelvic irradiation. Little is known about the factors predisposing to the development of radiation-associated rectal carcinoma. We present two patients who developed rectal carcinoma 17 and 26 years after radiotherapy for carcinoma of the uterine cervix. In one patient, mutation in exon 4 of the hMLH1 gene was detected. Radiation-associated rectal carcinoma represents a rare late toxicity of radiotherapy for cervical carcinoma that may occur in patients with a family history of colorectal carcinoma, including hereditary non-polyposis colorectal cancer.

    Despite advances in diagnostic and therapeutic modalities, the prognosis of gallbladder carcinoma is still poor. The purpose of this study is to look for peculiarities of primary gallbladder carcinoma in Jordan regarding its incidence, clinical and pathological aspects. A retrospective study over a period of 19 years comprising 66 patients was reviewed; only patients treated primarily in our hospital were included. There were 40 females and 26 males (ratio of 3:2). The main presenting symptom was abdominal pain in 54 patients (82%); correct preoperative diagnosis was made in only 20% of cases. Cholecystectomy alone was the most commonly performed operation (32 cases), cholecystectomy in combination with biliary bypass and/or hepatic resection (16 cases), biopsy of the gallbladder was performed in 12 cases and bypass with T-tube drainage in 6 cases. Postoperative morbidity and mortality were encountered in 48% and 18% respectively. The incidence and clinicopathological aspects of gallbladder cancer in Jordan seem to resemble that in the west, albeit with a lower age incidence. Diagnosis remains difficult and the outcome is still poor in the majority of cases.

    2014-11-21

    Hepatocellular carcinoma (HCC) is currently the sixth most common type of cancer with a high mortality rate and an increasing incidence worldwide. Its etiology is usually linked to environmental, dietary or life-style factors. HCC most commonly arises in a cirrhotic liver but interestingly an increasing proportion of HCCs develop in the non-fibrotic or minimal fibrotic liver and a shift in the underlying etiology can be observed. Although this process is yet to be completely understood, this changing scenario also has impact on the material seen by pathologists, presenting them with new diagnostic dilemmas. Histopathologic criteria for diagnosing classical, progressed HCC are well established and known, but with an increase in detection of small and early HCCs due to routine screening programs, the diagnosis of these small lesions in core needle biopsies poses a difficult challenge. These lesions can be far more difficult to distinguish from one another than progressed HCC, which is usually a clear cut hematoxylin and eosin diagnosis. Furthermore lesions thought to derive from progenitor cells have recently been reclassified in the WHO. This review summarizes recent developments and tries to put new HCC biomarkers in context with the WHOs reclassification. Furthermore it also addresses the group of tumors known as combined hepatocellular-cholangiocellular carcinomas.

    Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in some areas of the world. In most cases, HCC is diagnosed at a late stage. Therefore, the prognosis of patients with HCC is generally poor. The recommended screening strategy for patients with cirrhosis includes the determination of serum α-fetoprotein (AFP) levels and an abdominal ultrasound every 6 months to detect HCC at an earlier stage. AFP, however, is a marker characterized by poor sensitivity and specificity, and abdominal ultrasound is highly dependent on the operator's experience. In addition to AFP, Lens culinaris agglutinin-reactive AFP (AFP-L3), des-γ-carboxy prothrombin (DCP), glypican-3 (GPC-3), osteopontin (OPN), and several other biomarkers (such as squamous cell carcinoma antigen-immunoglobulin M complexes [SCCA-IgM], alpha-1-fucosidase [AFU], chromogranin A [CgA], human hepatocyte growth factor, insulin-like growth factor) have been proposed as markers for the early detection of HCC. For these markers, we describe the mechanisms of production, and their diagnostic and prognosis roles. None of them is optimal; however, when used together, their sensitivity in detecting HCC is increased. Recent research has shown that some biomarkers have mitogenic and migratory activities in the angiogenesis of HCC and are a factor of tumor growth. Copyright © 2012 Elsevier Inc.

  17. Etiopathogenesis of Differentiated Thyroid Carcinomas

    Directory of Open Access Journals (Sweden)

    Tanja Makazlieva

    2016-08-01

    Full Text Available INTRODUCTION: Thyroid malignomas are a heterogeneous group of neoplasm consisting of most frequent differentiated encountered carcinomas, papillary and follicular thyroid carcinoma, then medullary thyroid carcinoma originating from neuroendocrine calcitonin-producing C-cells and rare forms of thyroid lymphomas arising from intrathyroidal lymphatic tissue, thyroid sarcomas and poorly differentiated anaplastic thyroid carcinoma. There are increasing numbers of epidemiological studies and publications that have suggested increased incidence rate of thyroid carcinomas. We have read, analysed and compare available reviews and original articles investigating different etiological factors in the development of thyroid carcinomas through Google Scholar and PubMed Database. DISCUSSION: Aetiology involved in the development of thyroid carcinomas is multifactorial and includes external influences, as well as constitutional predispositions and genetic etiological factors. The actual effect of environmental and constitutional factors is on promoting genetic and epigenetic alterations which result in cell proliferation and oncogenesis. Until now are identified numerous genetic alterations, assumed to have an important role in oncogenesis, with MAPK and PI3K-AKT as crucial signalling networks regulating growth, proliferation, differentiation and cell survival/apoptosis. CONCLUSION: This new molecular insight could have a crucial impact on diagnosis and also on improving and selecting an appropriate treatment to the patients with thyroid malignancies.

    Sarcomatoid carcinomas are biphasic tumours, which occur at any site in the human body. It rarely affects the penis, with only 38 cases being reported in literature. It may be considered as a variant of squamous cell carcinoma or a dedifferentiated tumour. We report a 60-year old gentleman who presented with a swelling in the glans penis. He underwent a partial penectomy. Histopathology revealed sarcomatoid carcinoma of the penis, which was confirmed by immunohistochemistry. The rarity of this clinical entity makes its diagnosis difficult.

    Full Text Available Ameloblastic carcinoma is a rare odontogenic tumor exhibiting not only features of ameloblastoma but also features of carcinoma in either or both primary and metastatic lesions. Clinical features of this lesion are more aggressive and rapid than those of ameloblastoma. At times, it can metastasize to the lung or regional lymph nodes. Histologically, there is a picture of both ameloblastoma and carcinoma. Treatment is aggressive and has to be designed for each individual patient. English literature is sparse for this condition, as fewer cases have been reported till date. We report a series of four cases with different treatment modalities.

    Nasapharyngeal carcinoma is a rare disease. Oftenly, the diagnostic is made for advanced disease. Localized tumors, T1 or T2 NO observed a good prognosis and are locally controlled in more than 90 % of the cases by radiotherapy alone. The standard treatment of locally advanced disease is combined chemoradiation. A special vigilance of fast decrease of the volume of the pathological lymph nodes, sometimes associated to loss of weight might indicate an adaptive dosimetric revision. The treatment of recurrent disease is of great importance. Surgical indications are limited but should be discussed in multidisciplinary tumor board when possible. Surgical nodal sampling has to be proposed for nodal recurrence as well as reirradiation, which could be indicated according to the technical issues. Copyright © 2016. Published by Elsevier SAS.

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    Penile carcinoma frequency varies widely in different parts of the world and comprises 1-10% of all the malignancies in males. Majority of the cases of penile carcinoma are squamous cell carcinoma of penis comprising 60% to 70% of all cases. Warty carcinoma of penis is an unusual neoplasm and a variant of penile squamous cell carcinoma comprising 5%-10% of all the variants. The other histological variants include basaloid, verrucous, papillary, sarcomatous, mixed, and adenosquamous carcinoma. The various histological entities with an exophytic papillary lesions including warty carcinoma are together referred to as the "verruciform" group of neoplasms. The warty carcinoma has to be differentiated from these lesions and is typically distinguished by histological features of hyperkeratosis, arborescent papillomatosis, acanthosis, and prominent koilocytosis with nuclear pleomorphism. We present a case of 65-year-old male with growth measuring 6 × 4 cm in the penis who underwent total penectomy and was diagnosed as warty carcinoma penis.

    Full Text Available Abstract Objectives The aim of this study was to present a rare neoplasm, Primary myoepithelial carcinoma arising from the palate, and to review its diagnostic criteria, pathologic and clinical characteristics, treatment options and prognosis. Clinical Presentation and Intervention Myoepitheliomas are tumors arising from myoepithelial cells mainly or exclusively. Myoepitheliomas mostly occur in salivary glands, as well as in breast, skin, and lung. Case of myoepitheliomas in palate has rarely been reported. Myoepithelial carcinoma is malignant counterpart of myoepitheliomas. Adenomyoepithelioma is also a different disease from myoepitheliaomas. Immunohistochemically, tumor cells of myoepithelial carcinoma express not only epithelial markers such as cytokeratin, epithelial membrane antigen (EMA, but also markers of smooth muscle origin such as calponin. The immunohistochemical criteria of myoepithelial differentiation are double positive for both cytokeratins and one or more myoepithelial immunomarkers (i.e., S-100 protein, calponin, p63, GFAP, maspin, and actins. Myoepithelial carcinomas of salivary and breast demonstrate copy number gains and gene deletion. The overall prognosis of myoepithelial carcinoma is poor. There is rarely recurrence or metastasis in benign myoepithelial tumors. Complete excision with tumor-free margin is always the preferred treatment, while local radiation therapy and chemotherapy are suggestive treatment options. Here, a rare case of myoepithelial carcinoma arising from the palate has been described and discussed for the treatment and outcome. Pathological and clinical characters of myoepitheliomas are also compared and discussed. Conclusion The case report serves to increase awareness and improve the index of diagnosis and treatment of myoepitheliomas.

    Purpose: To retrospectively evaluate the effectiveness of radiotherapy with or without transarterial embolization (TAE) and/or percutaneous ethanol injection (PEI) in patients with hepatocellular carcinoma who were ineligible for surgery. Patients and Methods: From October 1984 to November 1997, 62 patients underwent radiotherapy receiving 50 to 70 Gy in 25 to 35 treatments with or without transarterial embolization and/or percutaneous ethanol injection and were followed for a median period of 8.6 months (1.5 to 92 months). Results: Overall median survival rates were 9.5 months. Significant prognostic factors were the extent of pretreatment liver function impairment, radiation field size and the existence of tumor thrombosis. Six-month and 1-year local control rates were 67 and 54%, respectively. Seven of the 8 patients who suffered from hepatic failure had poor pretreatment liver functions. Conclusion: Radiotherapy with or without transarterial embolization and/or percutaneous ethanol injection appears effective in controlling hepatocellular carcinoma and prolonged survival. Individualized treatment strategies are presented depending on the tumor presentation and the degree of liver function impairment. (orig.)

In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis. Alcohol consumption remains an important additional risk factor in the United States as alcohol abuse is five times higher than hepatitis C. Diagnosis is confirmed without pathologic confirmation. Screening includes both radiologic tests, such as ultrasound, computerized tomography, and magnetic resonance imaging, and serological markers such as α-fetoprotein at 6-month intervals. Multiple treatment modalities exist; however, only orthotopic liver transplantation (OLT or surgical resection is curative. OLT is available for patients who meet or are downstaged into the Milan or University of San Francisco criteria. Additional treatment modalities include transarterial chemoembolization, radiofrequency ablation, microwave ablation, percutaneous ethanol injection, cryoablation, radiation therapy, systemic chemotherapy, and molecularly targeted therapies. Selection of a treatment modality is based on tumor size, location, extrahepatic spread, and underlying liver function. HCC is an

    Patients with recurrent or locally advanced oesophageal carcinoma have a poor prognosis. Relief of dysphagia is often the goal of any further treatment. Several methods, including laser re-canalization, prosthetic intubation, dilatation, external beam irradiation (EBI) and intraluminal brachytherapy (IBT) can be used to alleviate dysphagia. In this retrospective review of 11 patients, eight with recurrent tumour and three newly diagnosed patients were treated with low dose rate IBT. Relief of dysphagia was achieved in nine patients, all of whom were able to maintain swallowing of at least a semi-solid diet until death or last follow-up. Toxicity was minimal, but survival was poor, with a median survival of only 3 months. IBT presents several advantages over other palliative methods, especially in recurrent tumours where re-treatment with EBI is often difficult because of normal tissue tolerance. Low dose rate IBT takes only 1-2 days to deliver, is highly effective, has little morbidity and the palliation achieved is relatively durable. 19 refs., 2 tabs., 1 fig.

    Full Text Available The occurence of squamous cell carcinoma on long-lasting ulcers is classic. Malignant transformation may occur on burn scars and chronic ulcers of varying etiology, including infectious agents. Transformation of old lobomycosis lesion scars into squamous cell carcinoma has been rarely reported. Careful and long-term follow-up of such patients is important to avoid carcinomatous transformation.A ocorrência de carcinoma espinocelular sobre lesões cutâneas de longa evolução é clássica em cicatrizes de queimadura e úlceras crônicas de etiologia variada, inclusive infecciosa. Na literatura, são raros os casos de pacientes com lobomicose de longa evolução que desenvolveram CEC. O seguimento cuidadoso desses pacientes é importante, pois, nas áreas de traumas, ulcerações e cicatrizes crônicas pode ocorrer degeneração carcinomatosa.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    2015-12-01

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors. Copyright © 2015 AEC.

    Sarcoidosis is a systemic granulomatous inflammation of unknown etiology, and seems to involve the liver parenchyma in most cases. However, sarcoidosis-associated hepatocellular carcinoma is rare. We report here a case in which a hepatocellular carcinoma occurred within the liver, which was probably involved as a result of systemic sarcoidosis. A 57-year-old Japanese man had been followed up for 2 years because of diabetic nephropathy and sarcoidosis. On admission for pneumonia, imaging studies revealed an unexpected hepatic tumor. Histology revealed a hepatocellular carcinoma accompanied by T-lymphocytic infiltration and marked granulomatous inflammation, which was surrounding some tumor nodules. The background liver parenchyma exhibited a moderate degree of fibrosis with granulomatous inflammation. The patient had no other apparent liver disease such as viral hepatitis, steatohepatitis, or primary biliary cirrhosis. Therefore, in the present case, sarcoidosis may be considered the probable background etiology for hepatocarcinogenesis.

    Parathyroid carcinoma is a rare disease of unknown etiology. This study presents a case of parathyroid carcinoma in a patient with tertiary hyperparathyroidism. Despite a successful kidney transplantation, the intact parathyroid hormone (iPTH) level of the patient was elevated consistently and could not be controlled by medical therapy. Due to the development of tertiary hyperparathyroidism with bone pain and osteoporosis, subtotal parathyroidectomy was performed 4 months after the kidney transplantation. Histological evaluation revealed that one of four parathyroid lesions was a parathyroid carcinoma, while the others were diffuse hyperplasia. Postoperative laboratory studies indicated a decreased level of iPTH. A positron emission tomography-computed tomography performed 6 months after the operation revealed no evidence of local recurrence or distant metastasis. Copyright © 2013.

    The authors studied 80 hepatocellular carcinomas from three continents for p53 gene (TP53) mutations and hepatitis B virus (HBV) sequences. p53 mutations were frequent in tumors from Mozambique but not in tumors from South Africa, China, and Germany. Independent of geographic origin, most tumors were positive for HBV sequences. X gene coding sequences of HBV were detected in 78% of tumors, whereas viral sequences in the surface antigen- and core antigen-encoding regions were present in less than 35% of tumors. These observations indicate that hepatocellular carcinomas are genetically heterogeneous. Mozambican-types of hepatocellular carcinomas are characterized by a high incidence of p53 mutations related to aflatoxins. In other tumors, the rarity of p53 mutations combined with the frequent presence of viral X gene coding sequences suggests a possible interference of HBV with the wild-type p53 function.

    Full Text Available Although rare in Canada and the United States, hepatocellular carcinoma (HCC ranks as the eighth most common cancer in the world. High-risk regions are East and Southeast Asia, and sub-Saharan Africa. Independent of race and geography, rates in men are at least two to three times those in women; this sex ratio is more pronounced in high-risk regions. Rates of HCC in the United States have increased by 70% over the past two decades. Registry data in Canada and Western Europe show similar trends. In contrast, the incidence of HCC in Singapore and Shanghai, China, both high-risk regions, has declined steadily over the past two decades. Among white and black Americans, there is an inverse relationship between social class status and HCC incidence. Chronic infection by the hepatitis B virus (HBV is by far the most important risk factor for HCC in humans. It is estimated that 80% of HCC worldwide is etiologically associated with HBV. In the United States, although the infection rate in the general population is low, HBV is estimated to account for one in four cases of HCC among non-Asians. Chronic infection by the hepatitis C virus is another important risk factor for HCC in the United States; however, this virus is believed to play a relatively minor role in the development of HCC in Africa and Asia. Dietary aflatoxin exposure is an important codeterminant of HCC risk in Africa and parts of Asia. In Canada and the United States, excessive alcohol intake, cigarette smoking and oral contraceptive use in women also are risk factors for HCC.

    Urachal carcinomas are rare neoplasms that constitute urachal carcinomas treated in our hospital. We carried out a retrospective, descriptive and observational study. Clinical files were reviewed of patients with diagnosis of bladder cancer and who were operated on with radical cystectomy with urinary substitution and extended partial cystectomy, selecting those patients with pathological report of urachal carcinoma. The study was conducted from January 1994 to May 2007 analyzing the following data: age, sex, symptoms, diagnostic methods, surgical approach, complications and disease-free survival. Of the 306 patients operated on with radical surgery for bladder cancer, only five patients (1.6%) had a diagnosis of urachal carcinoma. There were three (60%) men and two (40%) women, with a median age of 61 years. Hematuria was the chief complaint in all cases and the reason why they were initially treated with ultrasonography (USG). In one case, tumor of the right ovary was documented and the patient underwent exploratory laparotomy and extended partial cystectomy. In the other four cases, tumor was reported in the dome of the bladder and for this reason cystoscopy and transurethral resection of the bladder (TURB) were done, confirming the clinical findings in addition to the pathology report suggesting urachal carcinoma. Computed tomography (CT) confirmed the tumor in urachal topography, reporting a Sheldon clinical stage IIIb in three patients and stage IVa in one patient. This was the reason for the Studer-type orthotopic bladder substitution. Currently, four patients are being followed-up without recurrence, reporting only one death related to the disease. Urachal carcinomas are rare tumors with an incidence of 1.6% in our studied population. Symptoms in most cases are similar to those of bladder pathology origin. The surgical approach and procedure described here provide the best opportunity for disease-free survival.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

    Pathogenetic mechanisms of hepatocellular carcinoma (HCC) are still unclear and new tools for diagnostic and therapeutic purposes are ongoing. We have assessed whether squamous cell carcinoma antigen (SCCA), a serpin overexpressed in neoplastic cells of epithelial origin, is also expressed in liver cancer. Squamous cell carcinoma antigen was evaluated by immunohistochemistry in 65 HCCs of different aetiology and in 20 normal livers. Proliferative activity was assessed using MIB-1 antibody. In 18 surgical samples, tumour and nontumour liver tissue was available for SCCA cDNA amplification and sequencing. Squamous cell carcinoma antigen was detected in 55 out of 65 (85%) tumour specimens, but in none of the 20 controls. In the majority of the cases, the positive signal was found in the cytoplasm of more than 50% of the hepatocytes. Low or undetectable SCCA (scoreSCCA score >or=2 (mean+/-s.d.: 2%+/-2.4 vs 7.5%+/-10.3, PSCCA1 variant (G(351) to A) was identified in five cases, while SCCA1 was revealed in six cases and SCCA2 in three cases. In conclusion, SCCA variants are overexpressed in HCC, independently of tumour aetiology. A novel SCCA1 variant has been identified in one third of liver tumours.

    Sclerosing cutaneous neoplasms often represent a diagnostic challenge. The monoclonal antibody Ber-EP4 recognizes two glycopolypeptides found in most human epithelial cells. It is diagnostically highly reliable in the differentiation between basal cell carcinoma and cutaneous squamous cell carcinoma. In this study, we report its application in the differential diagnosis of microcystic adnexal carcinoma, desmoplastic trichoepithelioma and basal cell carcinoma. Biopsy samples from 28 sclerosing and infiltrating basal cell carcinomas, 13 microcystic adnexal carcinomas and 16 desmoplastic trichoepitheliomas were examined after immunohistochemical staining with Ber-EP4. Ber-EP4 did not label any of the microcystic adnexal carcinomas, whereas all 28 basal cell carcinomas were Ber-EP4 positive. Twenty-seven of the 28 showed moderate or strong staining intensity, with the majority being strong. Only one basal cell carcinoma was weakly positive. Twelve of the 16 desmoplastic trichoepitheliomas were immunoreactive with Ber-EP4 and the staining was more variable than those of basal cell carcinomas. Ber-EP4 reliably differentiates microcystic adnexal carcinoma from basal cell carcinoma to the same extent as it distinguishes the latter tumor from squamous cell carcinoma. While it stains the majority of desmoplastic trichoepitheliomas, these tumors still have to be considered in the differential diagnosis with microcystic adnexal carcinoma, when Ber-EP4 is applied.

    In colorectal carcinomas, tumor budding has been defined as the presence of isolated single tumor cells or small cell clusters in the stroma at the invasive tumor margin. In this study, the relationship between tumor budding density at the invasive tumor margin and pathological parameters is investigated. Haematoxylin and eosin stained slides of 73 cases with colorectal carcinoma were retrospectively evaluated for the presence and intensity of tumor budding by 2 observers. After the specimens were assessed, the highest density of tumor budding area was counted in a microscopic field of x200. Cases were separated into 2 groups according to tumor budding density as low grade ( tumor invasion, histological grade, vascular invasion and lymph node involvement was investigated. Of the 73 colorectal carcinoma cases, 33 (45.2%) had low and 40 (54.8%) had high grade tumor budding density, respectively. There was a statistically significant relationship between high grade tumor budding density and histological grade (p=0.042), lymph node involvement (p=0.0001) and vascular invasion (p=0.0034). High grade tumor budding density is associated with aggressive phenotypical features in colorectal carcinoma.

    1990-01-01

    Primary carcinoma of the gallbladder, while infrequent, is the most representative among the malignant neoplasms of the biliary tract. The diagnosis of carcinoma of the gallbladder was made in 22 out of 1252 operations performed for gallbladder disease (1.8%) since January 1980 through June 1988: only in 9% of the subjects a malignant tumor of the gallbladder was suspected preoperatively. In 21 cases the carcinoma was associated with chronic lithiasic cholecystitis. The 22 cases were assessed according to the classification proposed by Nevin. The operations performed were: 4 routine cholecystectomies (stages I and II) 4 cholecystectomies with lymphadenectomy (stages I and II); 4 cholecystectomies with lymphadenectomy and liver wedge resection of the bed of the gallbladder (stages II, III, IV, V); 7 explorative laparotomies and 3 gastrojejunal anastomoses (stage V). A complete follow-up was available for each of the 22 subjects: cumulative survival rates were calculated according to Kaplan-Meyer. The overall 5-year cumulative survival rate after operation was 19% for the whole group, whereas it reached 76% for the subgroup of 9 patients classified in stages I and II. This analysis reinforces the statement that surgical therapy can achieve excellent results if brought about before cancer overwhelms the muscular layer of the gallbladder wall. Thus, as the preoperative diagnosis of gallbladder carcinoma is extremely difficult and uncertain, any delay in performing cholecystectomy seems to be unwise in all those cases of chronic benign disease of the gallbladder (whether lithiasic in nature or not) that are suspected to be a major risk factor for cancer degeneration because of their frequent association with the carcinoma of the gallbladder.

  6. Metastatic renal cell carcinoma management

    Flavio L. Heldwein

    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.

    To study the diagnostic usefulness of immunohistochemical markers in distinguishing between invasive ductal carcinoma and invasive lobular carcinoma of breast. Twenty-four cases of grade I invasive ductal carcinoma, 12 cases of classic invasive lobular carcinoma and 14 cases of invasive carcinoma with mixed ductal and lobular features were retrieved from the archival files of Peking University First Hospital during the period from January, 1998 to December, 2001. Immunohistochemical study for E-cadherin, p120 catenin, epithelia membrane protein 1 (EMP1) and DVL1 was performed. The positivity rates for E-cadherin in grade I invasive ductal carcinoma and classic invasive lobular carcinoma were 83.3% (20/24) and 0, respectively (P invasive ductal carcinoma (membranous staining) and classic invasive lobular carcinoma (cytoplasmic staining). The positivity rates for EMP1 and DVL1 in gradeI invasive ductal carcinoma were 95.8% (23/24) and 54.2% (13/24), respectively; while those in classic invasive lobular carcinoma were 12 and 5 cases, respectively. E-cadherin and p120 catenin are useful immunomarkers for distinguishing between invasive ductal carcinoma and invasive lobular carcinoma.

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis. Os autores apresentam uma revisão da epidemiologia do carcinoma basocelular.Basal cell carcinoma is the most common malignant neoplasm in humans and its incidence has increased over the last decades. Its high frequency significantly burdens the health system, making the disease a public health issue. Despite the low mortality rates and the rare occurrence of metastases, the tumor may be locally invasive and relapse after treatment, causing significant morbidity. Exposure to ultraviolet radiation is the main environmental risk factor

    Aim. Gallbladder carcinoma is an uncommon cancer with a poor prognosis. In the era of laparoscopic cholecistectomy for treatment of benign diseases incidental gallbladder carcinoma has dramatically increased and now constitutes the major way patients present with gallbladder cancer and allows to detect cancer at early stages with a better prognosis. In this single-center study we report our experience with gallbladder carcinoma incidentally diagnosed during or after laparoscopic colecistectomy performed for cholelithiasis. Methods. From January 2003 to December 2011 a total of 1193 patients underwent cholecistectomy at General Surgical Unit III of University of Bari. The patients were 458 males and 735 females, mean age was 52 years (range 19-91). In 6 of 1188 patients adenocarcinoma was present in the pathologic specimens (0,5%). Results. Of 1188 patients in whom laparoscopic cholecistectomy was attempted adenocarcinoma was diagnosed histopathologically in 6 cases (0,5%). There was no suspicion of malignancy to any of them. Intraoperatively, gallbladder wall appeared abnormal in one patients and frozen section analysis revealed adenocarcinoma. In the remaining 5 cases routine histopathological studies revealed the diagnosis of gallbladder carcinoma. One patient had T1 tumor, two had T2 and three had T3 tumor. Conclusions. In the present study the rate of incidental gallbladder carcinoma was 0,5%, according to the published English language literature. The risk factors widely related to the gallbladder cancer are advanced age and gallstones disease. The therapeutic approach to gallbladder cancer was applied according to the stage of tumor, but in our study this was possible only in two patients with T2 and T3 tumor since high risk and important comorbidities were the main causes for the refusal of 3 patient out of 5. Only the T1 patient underwent simple cholecystectomy. Similar to other reports in this single-center study the diagnosis of incidental gallbladder

    Abstract The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has been considered a variant of mucin-secreting carcinoma with only intracytoplasmic mucin. The ...

    Full Text Available Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

    Full Text Available A formidable threat to the health of women, cervical carcinoma can be prevented in many cases with adequate screening. The current guidelines for cervical carcinoma screening were created as joint recommendations of the American Cancer Society (ACS, the American Society for Colposcopy and Cervical Pathology (ASCCP and the American Society for Clinical Pathology (ASCP in 2012, and later accepted and promoted by the American Congress of Obstetricians and Gynecologists (ACOG. The 2012 recommendations underscore the utility of molecular testing as an adjunct to cytology screening for certain women and provide guidance to clinicians based on different risk-benefit considerations for different ages. This manuscript will review screening techniques and current recommendations for cervical cancer screening and human papilloma virus (HPV testing, as well as possible future screening strategies.

    The ameloblastic carcinoma is an extremely rate, aggressive odontogenic neoplasm of the jaws. It is described as an ameloblastoma in which there is histologic evidence of malignancy in the primary or recurrent tumors, regardless of whether it has metastasized. We report an aggressive case of ameloblastic carcinoma of the mandible. A 68-year-old man with the complaint of the left facial swelling and intermittent pain was referred to our hospital. Serial images of panoramic radiograph, computed tomograph, and magnetic resonance imaging showed an ill-defined destructive radiolucent lesion of the left mandible.The lesion had typically aggressive behavior with extensive local destruction of bone and extended to the adjacent soft tissues. Bone scan revealed increased uptakes in the left mandibular body and ramous regions. Histological features were generally resembled with those of an ameloblastoma but with cytologic features of epithelial malignancy.

    2008-07-01

    Full Text Available Carcinoma telangiectaticum is an unusual type of cutaneous metastasis originating from various malignant tumors and characterized by telangiectases. This disorder appears with the spread of malignant cells to the skin via superficial lymphatics. It presents as small pink to purplish pseudovesicles, purpuric papules, plaques and telangiectases. A 58-year-old female patient with extensive internal organ metastasis, the primary of which could not be determined, was consulted for bluish lesion on her abdomen, while she was receiving cisplatinum and etoposide combination chemotherapy and radiotherapy. Histopathologic examination revealed that the superficial lymphatics in dermis were attacked by tumoral cells. Final diagnosis was established by clinical and histopathological findings as carcinoma telangiectaticum due to metastasis of a malignant tumor of unknown origin. Unfortunately our patient succumbed during her chemotherapy.

    To determine the frequency of HER2 genetic heterogeneity according to the recent American Society of Clinical Oncology (ASCO) and College of American Pathologists (CAP) definition (2009) in invasive breast carcinoma, and to identify clinicopathological features that characterise breast carcinomas with HER2 genetic heterogeneity. 530 invasive breast carcinomas were retrospectively analysed for HER2 genetic heterogeneity, and investigated for a potential association of HER2 genetic heterogeneity with other HER2 FISH findings, clinicopathological parameters, oestrogen/progesterone receptor expression and DNA cytometric parameters in breast carcinomas with an equivocal (2+) HER2 immunohistochemical score. The overall frequency of HER2 genetic heterogeneity was 14.7% in a cohort of 218 consecutive breast carcinomas. HER2 genetic heterogeneity was most frequent in invasive breast carcinomas with an equivocal (2+) HER2 immunohistochemical score. Among the 151 carcinomas lacking HER2 amplification, 16.1% showed HER2 genetic heterogeneity. In an extended cohort of 345 carcinomas with a (2+) HER2 score, the frequency of HER2 genetic heterogeneity was 41%, and was associated with the absence of HER2 gene clusters, chromosome 17 polysomy, histological tumour grade, DNA ploidy category and 5c exceeding rate. HER2 genetic heterogeneity according to the ASCO/CAP definition is frequent in breast carcinoma, and is most often present in carcinomas with an equivocal (2+) HER2 score. Many carcinomas with HER2 genetic heterogeneity have a negative HER2 amplification status, although they contain a significant number of tumour cells with HER2 gene amplification. Single cell scoring of the HER2/17 centromeric probe (CEP17) ratio is necessary to identify carcinomas with HER2 genetic heterogeneity, because they lack specific clinicopathological characteristics.

    Invasive lobular carcinoma of the breast is a relatively common diagnosis. However, other carcinomatous as well as noncarcinomatous neoplasms, either primary or metastatic to the breast, may mimic invasive lobular carcinoma. As treatment may differ, establishing the correct diagnosis is paramount to providing the appropriate care for these patients. This review outlines important mimics of invasive lobular carcinoma and the key clinicopathologic and immunohistochemical features as well as additional studies helpful in establishing their diagnoses.

    Diagnosis of sebaceous carcinoma of the periorbital region is often delayed. Clinically, this lesion can mimic several inflammatory disorders. Histopathologically, it can mimic either squamous cell or basal cell carcinoma. To identify an immunohistochemical approach to assist in the diagnosis of periorbital sebaceous carcinoma. The immunohistochemical profiles of several cases of periorbital sebaceous, basal cell, and squamous cell carcinoma were examined. Although at least focal epithelial membrane antigen (EMA) staining can effectively distinguish sebaceous carcinoma (10 of 11 were positive) from basal cell carcinoma (1 of 16 were positive), most squamous cell carcinomas examined were also focally EMA positive (11 of 14). However, Cam 5.2 reactivity was seen in most sebaceous carcinomas (8 of 11) but no squamous cell carcinomas (0 of 14). In addition, at least focal BRST-1 reactivity was also seen in most sebaceous carcinomas (7 of 11) but no basal cell carcinomas (0 of 16). Periorbital sebaceous, basal cell, and squamous cell carcinomas have different immunohistochemical staining profiles; a panel of commonly available antibodies, including anti-EMA, BRST-1, and Cam 5.2, may help distinguish these diseases from each other when that distinction cannot be clearly made by light microscopy alone.

    The rates of distant metastases and tumor death in sebaceous carcinoma (SC) have been reported to be higher than those of other cutaneous carcinomas, such as squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), regardless of whether they occur in ocular or extraocular regions. Therefore, strict differentiation of SC from SCC and BCC is required. In this article, we report immunohistochemical findings of SC and compare these data to those of SCC, BCC, and sebaceoma. An immunohistochemical study was performed using 7 antibodies [anti-carcinoembryonic antigen (CEA), anti-epithelial membrane antigen (EMA), anti-CA15-3, anti-CA19-9, anti-androgen receptor (AR), anti-epithelial antigen (Ber-EP4), and anti-adipophilin (ADP)] on 35 cases of SC (16 cases in ocular and 19 cases in extraocular regions) and 10 cases of each SCC (5 cases in ocular and 5 cases in extraocular regions), BCC (5 cases in ocular and 5 cases in extraocular regions), and sebaceoma (no cases arose on the eyelids). In summary, the typical immunophenotypes of SC were EMA+, CA15-3+, AR+, Ber-EP4-, and ADP+; those of sebaceoma were CEA-, EMA+, Ber-EP4-, and ADP+; those of SCC were CEA-, EMA+, CA19-9-, AR-, Ber-EP4-, and ADP-; and those of BCC were CEA-, EMA-, CA15-3-, Ber-EP4+, and ADP-. Other antibody tests for each neoplasm were positive in about half of the cases. The detection of AR and ADP was useful for differentiating SC from SCC, whereas the determination of EMA, CA15-3, Ber-EP4, and ADP was valuable in differentiating SC from BCC.

    Urachus' carcinoma represents a rare oncologic disease with an unfavourable prognosis due to the usual delay of correct diagnosis for its anatomical localization. Its surgical treatment varies from radical cystectomy to segmentary resection of the bladder with pelvic lymphadenectomy. We report a case occurred in a ninety years old female, in which the diagnosis was achieved only at laparotomy. The patient was submitted to surgery with the only generic diagnosis of "lower abdominal mass", and treated with segmentary resection.

    Background. Nested variant of urothelial carcinoma was added to the WHO's classification in 2004. Aims. To review the literature on nested variant of urothelial carcinoma. Results. About 200 cases of the tumour have been reported so far and it has the ensuing morphological features: large numbers of small confluent irregular nests of bland-appearing, closely packed, haphazardly arranged, and poorly defined urothelial cells infiltrating the lamina propria and the muscularis propria. The tumour has a bland histomorphologic appearance, has an aggressive biological behaviour, and has at times been misdiagnosed as a benign lesion which had led to a significant delay in the establishment of the correct diagnosis and contributing to the advanced stage of the disease. Immunohistochemically, the tumour shares some characteristic features with high-risk conventional urothelial carcinomas such as high proliferation index and loss of p27 expression. However, p53, bcl-2, or EGF-r immunoreactivity is not frequently seen. The tumour must be differentiated from a number of proliferative lesions of the urothelium. Conclusions. Correct and early diagnosis of this tumour is essential to provide early curative treatment to avoid diagnosis at an advanced stage. A multicentre trial is required to identify treatment options that would improve the outcome of this tumour. PMID:24587796

    Full Text Available Continual increasing of breast cancer in young women, its rare discovery in the early stage (stage I, as well as high mortality from this disease, are the facts that explain why the breast cancer is a target for many scientists. Thanks to the Greek scientist Papanicolaou and his report (l928, a successful battle with the most frequent carcinoma in women - PVU carcinoma, has begun.With the development of exfoliative, brushing and fine needle aspiration cytological methods, the impressive results have been achieved. While cytologic methods are used more and more in the breast oncopathology worldwide, up to this moment their applications have been rare in our country, which is one more reason for this study reason more for this study.By using the exfoliative and fine needle aspiration cytology, 50 patients were examined. The following cells were discovered: foamy macrophages, lipoprotein background, mastitis, eritrocytes, ductal tumorous papilles, apocrine metaplasia and ductal carcinomas. Furthermore, cytological caracteristics of the breast cancers and both advantages and limitations of the cytologic methods were pointed out. It was concluded that, using cytological methods, discovery of both precancerous breast lesions and breast cancer was possible in the earli stage. Also, sufficient knowledge of histopathology was necessary for correct interpretation of cytological results because of frequent mimicry in oncologic pathology.

    1997-01-01

    A prospective study was performed to determine the most reliable MRI criteria to distinguish recurrent rectosigmoid carcinoma from benign postoperative fibrosis. Twenty-two consecutive patients who were suspected to have recurrent rectosigmoid carcinoma were examined by T2 and precontrast and contrast enhanced T1 weighted images. The prospective interpretations, the presence of high signal on T2 weighted images, the shape of the margins of a mass and the degree of contrast enhancement were correlated with histology and follow up to determine their respective accuracies, sensitivities and specificities. The best criteria for recurrent tumor was the combination of high signal on T2 weighted images, round margins and > 40% contrast enhancement, which had an accuracy of 92%, sensitivity of 100% and specificity of 85%. In patients who were more than one year postoperative the specificity was 100%. The most reliable MRI criteria for distinguishing recurrent rectosigmoid carcinoma from benign postoperative fibrosis are the combination of the signal intensity on T2 weighed images, the shape of the margins of a mass and the presence of greater than 40% contrast enhancement.

    Full Text Available Background. Microcystic variant of urothelial carcinoma is one of the new variants of urothelial carcinoma that was added to the WHO classification in 2004. Aims. To review the literature on microcystic variant of urothelial carcinoma. Methods. Various internet search engines were used to identify reported cases of the tumour. Results. Microscopic features of the tumour include: (i Conspicuous intracellular and intercellular lumina/microcysts encompassed by malignant urothelial or squamous cells. (ii The lumina are usually empty; may contain granular eosinophilic debris, mucin, or necrotic cells. (iii The cysts may be variable in size; round, or oval, up to 2 mm; lined by urothelium which are either flattened cells or low columnar cells however, they do not contain colonic epithelium or goblet cells; are infiltrative; invade the muscularis propria; mimic cystitis cystica and cystitis glandularis; occasionally exhibit neuroendocrine differentiation. (iv Elongated and irregular branching spaces are usually seen. About 17 cases of the tumour have been reported with only 2 patients who have survived. The tumour tends to be of high-grade and high-stage. There is no consensus opinion on the best option of treatment of the tumour. Conclusions. It would prove difficult at the moment to be dogmatic regarding its prognosis but it is a highly aggressive tumour. New cases of the tumour should be reported in order to document its biological behaviour.

    Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

    Mammary analog secretory carcinoma (MASC) is a recently recognized low-grade salivary carcinoma characterized by a specific ETV6 rearrangement. We describe 14 new MASCs and examine their immunophenotypic and genetic profiles in the context of look-alikes, namely, low-and high-grade salivary duct carcinoma and acinic cell carcinoma. ETV6 rearrangement, and robust expression of mammaglobin and S100, were demonstrated in 11/11, 14/14, and 12/14 MASCs, respectively. All low-grade salivary duct carcinomas coexpressed S100/mammaglobin (6/6); none harbored ETV6 rearrangements (0/5). Given that S100/mammaglobin coexpression and absence of zymogen granules are features of both MASC and low-grade salivary duct carcinoma, these two are best distinguished histologically. The former is predominantly an extraductal neoplasm with bubbly pink cytoplasm, whereas the latter is a distinct intraductal micropapillary and cribriform process. Querying ETV6 gene status may be necessary for difficult cases. No acinic cell carcinoma expressed mammaglobin (0/13) or harbored an ETV6 rearrangement (0/7); only 1/13 acinic cell carcinomas weakly expressed S100. DOG1 expression was limited or absent among all tumor types, except acinic cell carcinoma which expressed DOG1 diffusely in a canalicular pattern. Therefore, histology and immunohistochemistry (mammaglobin, S100, DOG1) suffices in distinguishing acinic cell carcinoma from both MASC and low-grade salivary duct carcinoma. HER2 (ERBB2) amplification was detected in only 1/10 acinic cell carcinomas, but none of the MASCs or low-grade salivary duct carcinomas tested. High-grade salivary duct carcinomas frequently expressed mammaglobin (11/18) and harbored HER2 amplifications (13/15); none harbored ETV6 rearrangements (0/12). High-grade salivary duct carcinomas can easily be distinguished from these other entities by histology and HER2 amplification.

    Full Text Available Oesophageal malignancies are not an uncommon disease entity in this part of India. It is observed in both the sexes. Patients present with progressive dysphagia for solids. The duration of symptoms varies from 6 months to 2 years. Among the various aetiological factors, smoking, alcohol intake, spicy hot food intake, industrial pollution and achalasia cardia are a few worth mentioning. AIM OF THE STUDY To evaluate the differences in the predisposing factors causing squamous cell carcinoma and adenocarcinoma of oesophagus in this part of India. MATERIALS AND METHODS The study is conducted in the Department of Surgery at Government Medical College Hospital, Kozhikode; Kerala. One hundred patients attending the Department with history of Dysphagia were included after thorough history taking, clinical and endoscopic examination and found to have malignant growths in the oesophagus which was confirmed by biopsy and histopathological examination. Various aetiological factors were elicited and analysed in both the histological varieties of malignancy of oesophagus. OBSERVATIONS AND RESULTS Significant number of patients with history of paan chewing presented with histological picture of squamous cell carcinoma as compared to patients who had adenocarcinoma. Gastroesophageal reflux disease was more commonly associated with adenocarcinoma. Out of 37 patients with adenocarcinoma, 31 patients had history of gastroesophageal reflux disease (83.8%. 6 patients had no history of gastroesophageal reflux disease (16.2% within histology. Consumption of hot drinks, tea and coffee more than 10 per day has been analysed. 52 were consuming, 48 were not consuming, P value 0.179 non-significant. CONCLUSIONS Squamous cell carcinoma is more prevalent as compared to adenocarcinoma in present study. The main factor that has emerged is lifestyle, dietary habit, smoking and alcohol, and environmental factor. Consumption of alcohol and smoking is known risk factors in

    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.

    The purpose of this study was to evaluate and compare the sonographic findings of a conventional papillary carcinoma, follicular carcinoma and a follicular variant of a papillary carcinoma. A total of 308 nodules from 231 patients that were diagnosed with a papillary carcinoma and a follicular carcinoma by surgery after sonography were analyzed. The nodules consisted of a conventional papillary carcinoma (255, 83%), a follicular variant of a papillary carcinoma (25, 8%), and a follicualar carcinoma (28, 9%). We compared and analyzed the sonographic findings of each nodule for content, margin, echotexture, shape, calcification and halo sign. A conventional papillary carcinoma showed significant different sonographic findings than a follicular carcinoma and a follicular variant of a papillary carcinoma for an ill-defined or well-defined spiculated margin (63.1%), marked hypoechogenicity (85.9%) and microcalcification (49%). A follicular carcinoma showed a significant difference than a conventional papillary carcinoma for a well-defined smooth margin (92.9%), iso, hypo- or hyperechogenicity (89.3%), wider than tall shape (100%) and halo sign (82.1%). The follicular variant of a papillary carcinoma showed similar findings to a follicular carcinoma except for marked hypoechogenicity (44%, p = 0.006) and taller than wide shape (16%, p = 0.027). The follicular carcinoma and follicular variant of a papillary carcinoma showed similar sonographic findings, but findings of a conventional papillary carcinoma were different

    Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

  4. HER2-Positive Metaplastic Spindle Cell Carcinoma Associated with Synchronous Bilateral Apocrine Carcinoma of the Breast

    Full Text Available Apocrine carcinoma, which is strictly defined as over 90% of tumor cells showing apocrine differentiation, is a rare variant of breast cancer. Here we report an uncommon case in which apocrine carcinomas developed concurrently in both breasts; in addition, a sarcomatoid spindle cell lesion was coincident in the right breast. Both apocrine carcinomas were immunohistochemically negative for estrogen receptor (ER and progesterone receptor (PgR, but diffusely positive for androgen receptor (AR, GCDFP-15, and HER2. The presence of intraductal components in bilateral carcinomas and the absence of lymph node metastasis suggested that they were more likely to be individual primary lesions rather than metastatic disease. The spindle cell lesion showed a relatively well-circumscribed nodule contiguous with the apocrine carcinoma. HER2 oncoprotein overexpression was observed not only in the apocrine carcinoma, but also in the spindle cell lesion. Since the spindle cell component was intimately admixed with apocrine carcinoma and had focal cytokeratin expression, we diagnosed it as metaplastic spindle cell carcinoma, which was originated from the apocrine carcinoma. To our knowledge, this is the first case report of a patient with synchronous bilateral apocrine carcinomas coinciding with metaplastic carcinoma.

    The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has been considered a variant of mucin-secreting carcinoma with only intracytoplasmic mucin. The presence of extracellular mucin is a feature of ductal carcinoma. Herein is presented a case of lobular carcinoma with extracellular and intracellular mucin in a 43-year-old female patient, and confirmed by immunohistochemistry. Up to the present, infiltrating lobular carcinoma displaying extracellular mucin has not been described in the literature except two case.

    2013-10-01

    Basal cell carcinoma of the anal region is rare and morphologically difficult to distinguish from basaloid squamous cell carcinoma, particularly on biopsies. This distinction has therapeutic and prognostic implications. We reviewed morphological features of 9 basal cell carcinomas and 15 basaloid squamous cell carcinomas from the anal region diagnosed during 1993-2011 and determined the utility of Ber-EP4, BCL2, TP63, CK5/6, CDKN2A, and SOX2 as diagnostic tools. Immunostains were scored in a semi-quantitative manner (1+-1-10%, 2+-11-50%, 3+->50%). All basal cell carcinomas were located in the perianal region, while all basaloid squamous cell carcinomas originated in the anal canal/anorectum. Nodular subtype of basal cell carcinoma was the most common subtype. Retraction artifact was the only significant distinguishing histological feature of basal cell carcinoma compared with basaloid squamous cell carcinoma (88% vs 26%; P=0.04). Atypical mitoses were more common in basaloid squamous cell carcinomas (71% vs 11%; P=0.05). An in situ component was only present in basaloid squamous cell carcinomas, and was noted in 6/15 cases. Basal cell carcinomas had 2-3+ Ber-EP4 (basal cell carcinoma 100% vs basaloid squamous cell carcinoma 40%; Pbasal cell carcinomas 100% vs basaloid squamous cell carcinoma 33%; Pcarcinomas (basal cell carcinoma 0% vs basaloid squamous cell carcinoma 93%; Pbasal cell carcinoma from basaloid squamous cell carcinoma. An in situ component, when present, supports the diagnosis of basaloid squamous cell carcinoma. Immunostains are extremely helpful as diffuse Ber-EP4 and BCL2 expression is a feature of basal cell carcinoma and basaloid squamous cell carcinoma is typified by diffuse CDKN2A and SOX2 expression.

    Full Text Available Mucinous carcinoma is also known as mucoid carcinoma, colloid carcinoma, gelatinous carcinoma and mucin producing carcinoma. They are uncommon neoplasms of the breast and the reported incidence varies from 1-4%. Most of the mucinous carcinomas occur in older age group. FNAC can aid in diagnosis of mucinous carcinoma with only a few FNAC studies documented in literature. We present here a 56year old lady with a huge ulcerated breast mass clinically diagnosed as Malignant Phyllodes tumor. An FNAC was done which showed epithelial cell clusters with mild atypia in a background of both bluish violet and pink extracellular material. Spindle shaped cells were noted in the ground substance which led to a diagnosis of a phyllodes tumor with extensive myxoid change. Mastectomy was performed and the histopathological features confirmed a diagnosis of mucinous carcinoma. The tumor had areas showing thick collagenized fibrous septae separating tumor cell clusters and also areas of fibrosis. The pitfall in FNAC diagnosis may be due to the sampling from such an area.

    Thyroid carcinoma is the most common malignancy of the endocrine system and its incidence is still growing. The majority of thyroid tumors occur in sporadic form, however, some are inherited in families. The carcinomas can be divided into two groups according to the types of thyroid cells. Medullary thyroid carcinoma is derived from parafollicular C-cells. 20 - 25% of medullary thyroid carcinomas are inherited in multiple endocrine neoplasia type 2 syndromes. Genetic causes are activated by germ-line mutations in the RET proto-oncogene, which are transmitted autosomal, dominantly. At present the routine genetic screening and presymptomatic treatment (i.e. prophylactic total thyreoidectomy) on the basis of genotype-phenotype correlation has already been developed. The second group consists of carcinomas derived from follicular cells of thyroid that can be divided into differentiated (papillary and follicular) and nondifferentiated (anaplastic and poorly differentiated) ones. Also in this group 5-15% of carcinomas are cases of different familial syndromes (Gardner, Cowden, Werner syndromes and Carney complex) or only simple familial papillary thyroid carcinoma. Although the genetic basis of inherited cancer syndromes are mostly known (APC, PTEN, PRKAR1α and WRN genes), the cause of nonsyndromic familial papillary thyroid carcinoma is still under investigation, several predisposition genetic loci are recognized.

    Verrucous carcinoma, a variant of well-differentiated squamous cell carcinoma, is usually described in the literature as arising in the oral cavity, skin, and larynx. The reports on verrucous carcinoma arising in the genital tract, usually originating in the vagina, vulva, or uterine cervix, are few. Verrucous carcinoma arising in the ovary has not been previously reported. In this article, a unique hybrid carcinoma, a large aggressive verrucous carcinoma in combination with squamous carcinoma of the left ovary and synchronously occurring with a squamous cell carcinoma in the endometrium, is presented. This unique case of a hybrid carcinoma includes the first-known case of this type of carcinoma involving the ovary. The negative cervical evaluation findings, together with the histologic patterns of the tumors in the uterus and the ovary, support the conclusion that these 2 carcinomas are synchronous, one arising in the left ovary and the other arising in the uterus.

  3. Solid papillary breast carcinoma with mucinous differentiation

    Kostov Miloš

    2003-01-01

    Full Text Available A case is reported of a solid variant of infiltrating papillary carcinoma of the breast with mucinous differentiation in a 74-year-old woman. Macroscopically, the tumor was solid and lobular, 4.5 cm in diameter. Light microscopy showed solid papillary invasive carcinoma mixed with infiltrating ductal carcinoma, not otherwise specified. Abundant intracellular and extracellular acid mucin produced by the solid papillary tumor cells was proven histochemically by: PAS, PAS-D, mucicarmine and alcian blue. Immunohistochemically, the papillary carcinoma cells were strongly reactive to estrogen receptors, and weakly to moderately reactive to smooth muscle actin. We suggest that papillary carcinoma of the breast could have potentially high degree of aggressiveness, and that differential diagnosis of these rare tumors might be a histopathological problem.

    The purpose of this study is to evaluate mammographic findings of invasive ductal carcinoma (IDC) and invasive lobular carcinoma(ILC) and to find differential points between the two. 239 patients, who underwent mammography prior to surgery and were proved to have IDC(patients) or ILC(15 patients) pathologically, were analized retrospectively. On mammogram, presence of mass and microcalcification were analized. When there was a mass on mammogram, lesion opacity was classified into high, equal, or low opacity and border of the mass was classified into spiculated, poorly marginated, and well-marginated. When there was no definite mass, mammographic findings were classifie into asymmetric opacity and no mass. Masses were observed in 168 patients(75%) of IDC and 12 patients(80%) of ILC. Border of the masses were spiculated(n=50, 22.3%), poorly marginated(n=112, 50%), or well-marginated(n=6, 2.7%) in patients with IDC. Spiculated and poorly marginated borders were observed in 8 patients(53.3%) and 4 patients(26.7%) respectively, in patients with ILC. Microcalcifications were seen in 88 patients(17.3%) of IDC and patients(33.3%) of ILC. Although equal or low opacities were observed more frequently in ILC and microcalcifications were noted more frequently in IDC, it was difficult to differentiate the two diseases based on mammographic findings.

    Hepatocellular carcinoma (HCC) is one of the most frequent malignancies worldwide. A variety of pharmacological strategies has been evaluated in the treatment of HCC: classical chemotherapy, tamoxifen, octreotide, thymostimulin, pravastatin, (131)I-lipiodol as well as transarterial chemoperfusion (TAC) and chemoembolisation (TACE). TACE monotherapy or TACE combined with pravastatin resulted in a survival benefit of selected HCC patients. New strategies such as immunotherapy, antiangiogenic agents or cyclooxygenase inhibitors are under clinical investigation and might play a role in future therapies for HCC. Efficient strategies for the primary prevention of HCC are available and promising concepts in the secondary prevention have been reported.

    Full Text Available Nasopharyngeal carcinoma (NPC is prevalent in Taiwan and is characterized by a high frequency of nodal metastasis. The most common organs with distal metastases are the bones, lungs, and liver, with extremely rare cases to the pericardium. Herein, we report a rare case with NPC who presented with dyspnea and orthopnea. Serial studies, including pericardial biopsy, revealed NPC with pericardial metastasis and pericardial effusion. The tumor cells of both the original and metastatic tumors were positive for Epstein–Barr virus by in situ hybridization. This is the first histologically confirmed case of NPC with pericardial metastasis.

    Cancer of stomach, colon and liver are a group of the most common cancer in Korea. However, results with current therapeutic modalities are still unsatisfactory. The intensive efforts have been made to understand basic pathogenesis and to find better therapeutic tools for the treatment of this miserable disease. We studied the alteration of tumor suppressor genes and oncogenes in hepatocellular carcinoma in Korea. We found that alteration of Rb gene, APC were 33 %, 13 % respectively. But alterations of oncogenes such as myc, ras and mdm2 were rarely found. Our results suggests that HBV may act as oncogenic role in hepatocarcinogenesis instead of oncogenes. 6 figs, 2 tabs.

    Profound hypercalcemia can impose both diagnostic and therapeutic difficulties. First, profound hypercalcemia can be life-threatening as well as difficult to control. Second, the use of mithramycin in the treatment of severe hypercalcemia is emphasized. Third, hypercalcemia of hyperparathyroidism cannot be absolutely distinguished from that of malignancy. In the present case, the tubular reabsorption of phosphate, serum calcium levels, and measurement of immunoreactive parathyroid hormone (iPTH) suggested primary hyperparathyroidism, yet ectopic iPTH from a cervical carcinoma was the probable cause of the hypercalcemia.

    Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

    Rhabdoid colonic tumors are very rare lesions with just a few publications describing such neoplasms. Even more unusual for these lesions are their primary rectal locations, with only two brief case reports having been published on that subject to date. We present a case of a composite rhabdoid rectal carcinoma in a 49-year-old male. The tumor behaved very aggressively, with rapid patient demise despite radical surgery and intensive postoperative chemotherapy (FOLFIRI [folinic acid {leucovorin}, fluorouracil {5-fluorouracil}, and irinotecan] and FOLFOX4 [folinic acid {leucovorin}, fluorouraci {5-fluorouracil}, and oxaliplatin]). Pathologic examination was supportive of a rhabdoid carcinoma, with a compatible immunohistochemical profile, demonstrating synchronous expression of vimentin and epithelial markers in the tumor cells. In addition, BRAF V600E gene mutation, together with a wild-type KRAS gene, was identified, and no evidence of microsatellite instability based on MLH1, MSH2, MSH6, and PMS2 immunophenotypes, i.e., no loss of expression for all 4 markers, was observed. Our reported case confirms previously published observations of the clinical aggressiveness and the poor therapeutic response for rhabdoid tumors. PMID:24466541

    Human papillomavirus (HPV) infection is the most common sexually transmitted disease worldwide and can result in pre-malignancies or overt malignancies of the skin and mucosal surfaces. HPV-related illnesses are an important personal and public health problem causing physical, mental, sexual and financial detriments. Moreover, this set of malignancies severely affects the immunosuppressed population, particularly HIV-positive patients and organ-transplant recipients. There is growing incidence of HPV-associated anogenital malignancies as well as a decrease in the average age of affected patients, likely related to the rising number of high-risk individuals. Squamous cell carcinoma is the most common type of HPV-related malignancy. Current treatment options for HPV infection and subsequent disease manifestations include imiquimod, retinoids, intralesional bleomycin, and cidofovir; however, primary prevention with HPV vaccination remains the most effective strategy. This review will discuss anogenital lesions in immunocompromised patients, cutaneous warts at nongenital sites, the association of HPV with skin cancer in immunocompromised patients, warts and carcinomas in organ-transplant patients, HIV-positive patients with HPV infections, and the management of cutaneous disease in the immunocompromised patient.

    Non melanoma skin cancers (NMSC) are the most common human neoplasms, encompassing basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), but also cutaneous lymphomas, adnexal tumors, merckel cell carcinoma and other rare tumors. The incidence of BCC and SCC varies significantly among different populations, and the overall incidence of both tumors has increased over the last decades. Although generally associated with a favorable prognosis, recent evidence suggests that the mortality rates of SCC might have been underestimated up-to-date.1 According to Medicare data, NMSC is the fifth most expensive cancer for health care systems. This increased economic burden is not associated with the cost of treating an individual patient, but with the large number of affected patients and the recurrence rates.2 Therefore, the adequate management of the primary tumor with a complete excision becomes a priority not only for the patient but also for the public health systems. Multiple treatment modalities are currently usedin clinicalpractice for the treatment of NMSC. While surgical excision (SE) remains the gold standard of care, non-surgical techniques have gained appreciation due to lower morbidity and better cosmetic results. The optimal management of treatment includes a complete tumor clearance, preservation of the normal tissue function, and the best possible cosmetic outcome.3 Surgery with a predefined excision margin is the treatment of choice for most NMSCs, with Mohs micrographic surgery being recommended for tumors considered to be at a higher recurrence risk or those developing on cosmetically sensitive areas.4, 5 Therefore, the surgical approach of a NMSC consists with three different and equally important steps. First the preoperative clinical assessment of the tumor margins, which can be facilitated by the use of dermoscopy. Second, the definition of the surgical margins depending on the tumor subtype and its biological behavior. Finally, the surgical

    Full Text Available OBJECTIVE: The majority of cases of hepatocellular carcinoma have been reported in individuals with cirrhosis due to chronic viral hepatitis and alcoholism, but recently, the prevalence has become increasingly related to nonalcoholic steatohepatitis around the world. The study aimed to evaluate the clinical and histophatological characteristics of hepatocellular carcinoma in Brazilians' patients with nonalcoholic steatohepatitis at the present time. METHODS: Members of the Brazilian Society of Hepatology were invited to complete a survey regarding patients with hepatocellular carcinoma related to nonalcoholic steatohepatitis. Patients with a history of alcohol intake (>20 g/day and other liver diseases were excluded. Hepatocellular carcinoma diagnosis was performed by liver biopsy or imaging methods according to the American Association for the Study of Liver Diseases’ 2011 guidelines. RESULTS: The survey included 110 patients with a diagnosis of hepatocellular carcinoma and nonalcoholic fatty liver disease from nine hepatology units in six Brazilian states (Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Paraná and Rio Grande do Sul. The mean age was 67±11 years old, and 65.5% were male. Obesity was observed in 52.7% of the cases; diabetes, in 73.6%; dyslipidemia, in 41.0%; arterial hypertension, in 60%; and metabolic syndrome, in 57.2%. Steatohepatitis without fibrosis was observed in 3.8% of cases; steatohepatitis with fibrosis (grades 1-3, in 27%; and cirrhosis, in 61.5%. Histological diagnosis of hepatocellular carcinoma was performed in 47.2% of the patients, with hepatocellular carcinoma without cirrhosis accounting for 7.7%. In total, 58 patients with cirrhosis had their diagnosis by ultrasound confirmed by computed tomography or magnetic resonance imaging. Of these, 55% had 1 nodule; 17%, 2 nodules; and 28%, ≥3 nodules. CONCLUSIONS: Nonalcoholic steatohepatitis is a relevant risk factor associated with hepatocellular carcinoma in

    Ultraviolet light (UV) is an important risk factor for cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin. These cancers most commonly affect persons with fair skin and blue eyes who sunburn rather than suntan. However, each of these cancers appears to be associated with a different pattern of UV exposure and to be mediated by different intracellular molecular pathways.Some melanocortin 1 receptor (MC1R) gene variants play a direct role in the pathogenesis of cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma apart from their role in determining a cancer-prone pigmentory phenotype (fair skin, red hair, blue eyes) through their interactions with other genes regulating immuno-inflammatory responses, DNA repair or apoptosis.In this short review we focus on the aetiological role of UV in cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin, and on some associated biopathological events.

    Lobular carcinoma in situ (LCIS) is a known risk factor for invasive breast carcinoma, but there is increasing data indicating a possible precursor relationship. This study investigates the incidence of lobular carcinoma in situ that occurs with invasive lobular carcinoma (ILC). Women diagnosed with ILC or LCIS from 2000 to 2010 were retrospectively identified and reviewed after institutional review board approval. This group was divided into two cohorts: ILC alone, and LCIS and ILC (ILC/LCIS). Patient demographics, disease characteristics, and treatment modalities were captured. p carcinoma in situ identified with invasive ductal carcinoma at ∼40%. The association of pre-invasive and invasive lobular lesions should be further studied in a large scale prospective study to assess for a precursor relationship. Copyright © 2014 Elsevier Ltd.

    Intracystic papillary carcinoma of the breast (ICP) is a rare form of noninvasive breast cancer. The average age of onset is 65 years. Patients with ICP have a greater than 15-year survival rate advantage compared to patients with other breast carcinomas. There have been no reports of disease-related deaths in patients with ICP and no increased risk of disease in the contralateral breast. No definitive conclusions have been made regarding adjuvant treatment; however, ICP should generally be treated like ductal carcinoma in situ (DCIS). Tamoxifen is often recommended.

    Full Text Available Buccal carcinoma is one of the most common oral malignant neoplasms, especially in the South Asian region. Radiotherapy, which plays a significant role in the treatment of this carcinoma, has severe adverse effects. Different types of prosthesis may be constructed to protect healthy tissues from the adverse effects of treatment and concentrate radiation in the region of the tumor mass. However, the technique for fabrication of shielding stent with Lipowitz's alloy (cerrobend/Wood's alloy has not been well documented. This article describes detailed technique for fabrication of such a stent for unilateral buccal carcinoma patients to spare the unaffected oral cavity from potential harmful effects associated with radiotherapy.

    Full Text Available Pancreatic carcinoma is the fourth-leading cause of cancer death and is characterized by early invasion and metastasis. The developmental program of epithelial-mesenchymal transition (EMT is of potential importance for this rapid tumor progression. During EMT, tumor cells lose their epithelial characteristics and gain properties of mesenchymal cells, such as enhanced motility and invasive features. This review will discuss recent findings pertinent to EMT in pancreatic carcinoma. Evidence for and molecular characteristics of EMT in pancreatic carcinoma will be outlined, as well as the connection of EMT to related topics, e.g., cancer stem cells and drug resistance.

    Thirty patients with recurrent primary nasopharyngeal carcinoma were reirradiated between 1949 and 1976. Twenty eventually demonstrated recurrence at or near the primary site, involving the nasopharynx in 4 and the central nervous system in 16. Long-term palliation was often achieved, and there were no severe complications except for one patient who died of necrosis of the base of the skull. The most frequent problems were hearing loss and trismus; necrosis of the nasopharynx was seen in only 2 patients. With therapy in the range of 18-25 MeV, significant palliation and an occational cure can be achieved without excessive risk. Recurrent disease involving the skull may be controlled for several years using current techniques.

    Full Text Available Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC. Although radiofrequency (RF ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect. Cryoablation destroys tissue via direct tissue destruction and vascular-related injury. A few recent comparative studies have shown that percutaneous cryoablation for HCCs is comparable to percutaneous RF ablation in terms of long term therapeutic outcomes and complications. Cryoablation has several advantages over RF ablation such as well visualization of iceball, no causation of severe pain, and lack of severe damage to great vessels and gallbladder. It is important to know the advantages and disadvantages of cryoablation compared with RF ablation for improvement of therapeutic efficacy and safety.

    Aim: The article focuses on the radioprotective effect of acute hypoxia on healthy tissues during preoperative accelerated hypoxyradiotherapy of colorectal carcinoma performed as locoregional irradiation including the common iliac lymph nodes. Analysis of early and late side effects and complications. Patients and Methods: In this prospective study, early and late complications were assessed in 50 patients as a function of hypoxyradiotherapeutic dose increase. The preliminary treatment results of this radiotherapeutic modification were evaluated after a median follow-up of 48 months using Kaplan-Meier analysis. Between April 1991 and February 1997, 50 patients (36 men and 14 women) with colorectal carcinoma were treated preoperatively with locoregional accelerated hypofractionated hypoxyradiotherapy. The extent of disease was classified according to Dukes' criteria (A: four patients, B: 28 patients, C: 18 patients). We used a 20-MeV linear accelerator with two parallel opposed fields. Hypoxyradiotherapy was performed extending from the perineum to the L4 region. Acute hypoxia was induced during irradiation by ventilation of a hypoxic gas mixture containing 7.8-8.0% oxygen. Total doses of 24 Gy/8 days, 28 Gy/9 days, and 32 Gy/10 days were applied in five, 20, and 25 patients, respectively. Low anterior resection or abdominoperineal amputation of the rectum was performed the day after completion of preoperative hypoxyradiotherapy. The early reactions after irradiation were evaluated according to the Common Toxicity Criteria of the National Cancer Institute (CTC-NCI). Results: Early postirradiation proctitis was documented in three and early radiation-induced cystitis in two patients only. Neither early nor late radiation-associated complications were observed in any of the three hypoxyradiotherapy schedules during the follow-uper period of 6-105 months. Based on Kaplan-Meier analysis (median 48 months), a 5-year overall survival rate of 61.5% and a local relapse

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Carcinoma of the prostate is one of the most frequent tumours in men over the age of 40. The early recognition of the carcinoma is only possible by rectal palpation which is due to the absence of symptoms. For the diagnosis, in all cases giving reason to suspicion concerning the rectal region a biopsy of the suspicious region is necessary. The classification of the carcinoma in clinical stages (TNM, A to D) provides the possibility to compare. More important than the clinical stage of the tumour is the histopathological grading of the tumour, i.e. its degree of malignity (G/sub 1/ to G/sub 3/) for the prognosis. The phosphatases, the excretory urogram, the bone scintiscanning, X-ray examinations of the skeleton and thorax, sonography, computerized tomography, and lymphography are not suitable for the early recognition of carcinoma of the prostate. These examinations serve to determine the stage of the tumour.

    Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

    Gallbladder carcinoma is about 0.5% of all cancer. The outcome of patients with gallbladder carcinoma is overall bad and the only potentially curative treatment is surgery. The aim of this study was to determine the disease's prevalence in Iceland and outcome of the patients diagnosed in the study period. This was a retrospective study of all diagnosed patients with gallbladder carcinoma during the years 2004-2013. A list of patients was obtained from the Icelandic Cancer Registry. Information was gathered from the patient's charts in Landspitali University Hospital and the Hospital in Akureyri. Descriptive statistics was used to analyze the results. Median follow-up time was 6 years. Twenty-four patients were diagnosed with gallbladder carci-noma in Iceland during the study period, 16 women and 8 men. Eighteen patients were diagnosed in Landspitali and six in the Hospital in Akureyri. The average age at diagnosis was 73 years. Eighteen patients have died, on average 5 months after the time of diagnosis. Adenocarcinoma was the most common cancer type (n=19). Three patients (3/24, 12.5%) underwent extended operation following the diagnosis of the gallbladder carcinoma. Nine patients (9/24, 37.5%) had advanced disease at the time of diagnosis and died within two months after being diagnosed with gallbladder carcinoma. Gallbladder carcinoma is a rare cancer type in Iceland and has a bad prognosis. One third of the patients had no connection with Landspitali University Hospital following the diagnosis. Extended surgery following the diagnosis was seldom performed. Key words: gallbladder carcinoma, gastrointestinal cancer, adenocarcinoma, extended cholecystectomy.

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    2015-06-01

    A case of a 53-year-old woman with the epithelioid variant of mammary myofibroblastoma, which was initially misinterpreted as invasive lobular carcinoma, is presented. A needle core biopsy of the 1.6 cm mass showed interlacing bundles of epithelioid myofibroblasts amid dense fibrous tissue associated with lobular carcinoma in situ of the classical type. Most epithelioid cells showed nuclear atypia, and a few exhibited signet-ring cytology. Immunoreactivity for estrogen and progesterone receptors further compounded the deception, and the neoplasm was misinterpreted as invasive lobular carcinoma. Excisional biopsy showed a circumscribed stromal tumor with foci suspicious for invasive lobular carcinoma. The latter was excluded by cytokeratin negativity throughout the tumor. The overall histopathological appearance and immunostaining pattern was confirmatory of myofibroblastoma. This case report emphasizes the potential for mistaking epithelioid myofibroblastoma for invasive lobular carcinoma--particularly in the setting of limited sampling, hormone-receptor immunoreactivity of the lesional cells, and synchronous lobular carcinoma in situ. © The Author(s) 2015.

    Aims—The mutual relation of lobular carcinoma in situ (LCIS) and ductal carcinoma in situ (DCIS) of the breast, as accepted precursor lesions of invasive breast cancer, is controversial. Because they display genetic heterogeneity, it is not clear how genetically advanced these entities are and what causes the transition to an invasive carcinoma. Methods—Six cases of LCIS, four of them with associated lobular invasive carcinoma, four cases of intermediately differentiated DCIS with an associated invasive lobular carcinoma, and nine cases of intermediately and poorly differentiated DCIS with associated ductal invasive carcinoma were investigated by means of comparative genomic hybridisation (CGH) after microdissection and immunohistochemical staining of E-cadherin. Results—LCIS was characterised by a low average rate of copy number changes, no evidence of amplifications, and a high rate of gains and losses of chromosomal material at 1q and 16q, respectively. A high degree of genetic homology with well differentiated DCIS was obvious, as reported previously. The cases of intermediately differentiated DCIS with associated lobular invasive components and lobular differentiation revealed striking homologies, and a significant difference of E-cadherin expression. The comparison of preinvasive and invasive breast lesions, irrespective of differentiation within the same patient, revealed no specific alteration that might be associated with invasion. Genetic alterations seen in invasive carcinoma were not necessarily seen in the adjacent precursor lesions. Conclusions—These results provide strong evidence that invasive breast cancer is a disease with multiple cytogenetic subclones already present in preinvasive lesions. Moreover, specific CGH alterations associated with invasion were not observed. Furthermore, the close genetic association between well differentiated and a subgroup of intermediately differentiated DCIS and LCIS led to the hypothesis that LCIS and a

    Epithelial carcinomas occasionally have sarcomatous components that consist primarily of spindle and cuboidal cells, which often resemble osteoblasts. Sarcomatoid carcinomas consist of similar cells. Recent studies have characterized these phenomena as a manifestation of epithelial-mesenchymal transition in carcinoma cells, but the mesenchymal phenotypes that manifest in sarcomatous cells of epithelial carcinomas are not well understood. Here, we examined the expression profiles of four osteoblastic differentiation biomarkers in the sarcomatous components of multiple carcinoma types, including five renal clear cell, four breast invasive ductal, two esophageal, one maxillary squamous cell, three larynx, three lung, one liver, and one skin sarcomatoid carcinoma. Expression was analyzed by immunohistochemistry using antibodies against cell adhesion molecule 1, a member of the IgCAM superfamily, osterix transcription factor (Osterix), cluster of differentiation 151, a transmembrane 4 superfamily member, and alkaline phosphatase. Immunostaining intensity was rated in scale 0 (negative), 0.5 (weak), and 1 (strong) for each marker, and the four scale values were summed to calculate osteoblastic scores. In all, 10 cases had a osteoblastic score ≥3, and all of these 10 cases were cell adhesion molecule 1- and Osterix-positive. Eight and five of the nine samples with a osteoblastic score carcinoma cells and that cell adhesion molecule 1 could be a useful marker for identifying this phenomenon in carcinoma tissues.

    GATA3 plays a role in cell proliferation and differentiation in many tissues, including breast, and it has been suggested that GATA3 expression correlates with ER expression. However, little is known on GATA3 expression in various subtypes of breast carcinoma, its utilization in cytology, and on how GATA3 performs in comparison with GCDFP-15 and mammaglobin. Eighty-four histology cases of breast carcinoma of various subtypes, including 28 triple-negative breast carcinomas, along with 20 cytology cases of metastatic breast carcinoma and 12 cytology cases of ER-positive metastatic gynecologic malignancies, were stained for GATA3, GCDFP-15, and mammaglobin. In non-triple-negative breast carcinomas (n=56), GATA3 showed 100% sensitivity, higher than GCDFP-15 (42.8%; Pcytology cases, 100% stained with GATA3, higher than GCDFP-15 (20%; Pgynecologic malignancies. Thus, in working up ER-positive metastatic malignancies GATA3 demonstrates specificity for breast.

    Full Text Available Abstract Background The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. Materials and methods Fifty three paraffin blocks of different lesions (15 muco-epidermoid carcinoma, 14 adenoid cystic carcinoma, 3 epi-myoepithelial carcinoma, 5 salivary duct carcinoma, 5 malignant pleomorphic adenoma, 6 polymorphous low grade adenocarcinoma and 5 acinic cell carcinoma were prepared for immunohistochemical staining with maspin and MCM2 antibodies. ANOVA and Pearson correlation tests were used for the statistical analysis of the results. Results All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis. Conclusions Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.

    The classification of squamous cell carcinomas, based on cellular differentiation features, includes the poorly differentiated epidermoid carcinomas and well-differentiated epidermoid carcinomas. The histogenetic cytologic data clarify conventional cytodiagnosis of poorly differentiated epidermoid carcinomas and poorly differentiated adenocarcinoma, and also eliminate other categories such as large cell carcinoma and small cell anaplastic carcinoma. We conducted a study for evaluating the degree of differentiation of pulmonary squamous cell carcinoma in 620 patients - 551 men (88.8%) and 69 women (11.1%) who had lung cancer confirmed by cytologic, histologic and bronchoscopic examination. The cytologic examination was performed on slides with samples obtained by bronchial brushing and prints of bronchial biopsy stained with the Giemsa method. Histopathologic examination was performed on samples obtained by bronchial biopsy and stained with Hematoxylin-Eosin. At cytologic examination we found: poorly differentiated epidermiod carcinomas in 66 cases (33.8%), moderately differentiated epidermoid carcinomas in 22 cases (11.2%) and well differentiated epidermoid carcinomas in 107 cases (54.8%). Histological examination revealed: poorly differentiated epidermoid carcinomas in 133 cases (45.7%), moderately differentiated epidermoid carcinomas in 32 cases (10.9%), and well differentiated epidermoid carcinomas in 126 cases (43.2%). Our results suggested the importance of the association between cytologic and histopatologic examinations in the diagnosis of lung cancer.

    To investigate the risks for occult carcinoma in contralateral nodules for unilateral papillary thyroid carcinoma. The study included 157 consecutive cases of unilateral papillary thyroid carcinoma with benign nodules in the contralateral lobe identified by preoperative ultrasound or fine-needle aspiration from January 2011 to December 2013. The patients received total thyroidectomies and neck lymph node dissections. The frequency and predictive factors for contralateral occult carcinoma in these patients were analyzed. A total of 68 patients (43.3%) had occult papillary thyroid carcinoma in the contralateral lobe and the maximum diameter of contralateral occult papillary carcinoma ranged from 0.1 to 1.2 cm, including ≤ 0.5 cm in 56 patients, 0.5-1.0 cm in 9 patients and >1.0 cm in 3 patients respectively. In univariate analysis, occult carcinoma in the contralateral lobe was associated with patient age (χ(2) = 7.266, P = 0.007) and pathologically multifocality in the ipsilateral lobe (χ(2) = 5.090, P = 0.024), but not with family history, tumor size, thyroid function, Hashimoto's thyroiditis, perithyroidal invasion, multifocality in the ipsilateral lobe, clinically or pathologically node-negative neck. In multivariate Logistic an analysis, age (OR = 1.054, P = 0.001) and multifocality in the ipsilateral lobe on final pathology (OR = 2.443, P = 0.021) were independent predictive factors for contralateral occult papillary thyroid carcinoma. Occult carcinoma is common in the contralateral "benign" nodules in patients with unilateral papillary thyroid carcinoma especially in young patients or the cases with multifocal tumors.

    Uroplakin II antibody is exclusively specific for urothelial carcinoma. Nonurothelial carcinoma has not been reported to be immunoreactive for uroplakin II. In the present study, we hypothesized that breast carcinoma showing apocrine differentiation, such as invasive pleomorphic lobular carcinoma (IPLC) and apocrine carcinoma (AC), stains positive for uroplakin II. We identified 6 cases of IPLC between 2000 and 2014 by searching a computerized pathological database. We randomly selected 10 cases of each classic invasive lobular carcinoma (cILC) and AC and five cases of apocrine metaplasia (AM) that coexisted in a surgically resected breast carcinoma specimen. Immunohistochemistry was performed for uroplakin II, GATA3, CK7, CK20, and other representative markers positive for urothelial carcinoma. All cases of IPLC, AC, and AM, except those of cILC, showed immunoreactivity for uroplakin II. Poorly differentiated urothelial carcinoma sometimes shows similar morphology to IPLC with the following immunophenotype: CK7+, CK20-, GATA3+, and uroplakin II+. In the present study, this immunophenotype was observed in all the cases of IPLC and AC. Therefore, when studying metastatic, poorly differentiated carcinoma showing the aforementioned immunophenotype, we should consider the possibility of it being IPLC in addition to metastatic urothelial carcinoma.

    The incidence of hepatocellular carcinoma (HCC) in Europe and throughout the world is currently increasing. This is caused by an increase in the number of patients with alcoholic liver damage, metabolic syndrome, and by increasing incidence of hepatitis B and C.From January 1, 2004 to December 31, 2013, resection or radiofrequency ablation of the liver was done in 360 patients with benign lesions or malignant tumors of the liver. In 28 patients HCC was diagnosed and histologically confirmed (7.8 %). Seven patients had HCC associated with liver cirrhosis (25 %), and 21 patients were without histologically confirmed cirrhosis (75 %). R0 resection was done in 18 (64 %) patients.Surgical complications occurred in 6 (21 %) patients and reoperation due to tumor relapse or progression was done eight times in 6 (21 %) patients. One-year and five-year patients' survivals were 64 % and 10 %, repectively, and did not statistically differ from the survival of the whole set of patients with tumor diseases in the given time period. In the future it will be possible to improve the long-term survival of patients with HCC by using screening methods for presymptomatic diagnosis of HCC, precise preoperative diagnosis and efforts for R0 resection (Tab. 1, Fig. 4, Ref. 11).

    A curative effect of high dose proton irradiation for hepatoma was investigated. In cases of single nodular type HCC, radiation field was limited to tumor, and in cases of multi nodular type HCC, irradiation was also fractionated. An average dose of radiation was 4 Gy/time, average times were 16, and an average total dose was 72 Gy. Tumor size reduction rate at 6 months after proton irradiation (123 cases) was CR (17.9%), PR (52.0%), NC (29.3%) and PD (0.8%). And the reduction rate of tumor size in monotherapy cases was 100% (after 3 weeks), 96% (after 1 year) and 88% (after 2 years). The local control rate was 99.1% (after 1 year) and 91.4% (after 3-5 years). AFP value significantly decreased from 571.0{+-}1266.6 ng/ml before radiation to 145.4{+-}346.3 ng/ml after radiation (p<0.0005). The recurrence after radiation occurred more at outside of radiation field, significantly. Indication basis of proton irradiation was showed in this article. Because selective radiation is possible, the proton irradiation should be optimum therapy in specific carcinomas of deep organ. (K.H.)

    As in other malignant tumors, prognosis in renal cell carcinoma (RCC) depends on tumor extent and metastasis at the time of primary diagnosis. Staging systems formalize the way in which the extent of RCC is being described and classified. Primary staging of RCC aims at evaluating surgical options. Since surgical excision, which is the mainstay of therapy in non-metastatic RCC, and, recently, minimally invasive ablation methods have evolved significantly over the last decades, staging systems continue to evolve along the way. The 40-year-old Robson classification has been replaced with the TNM classification of RCC, because the latter adapts more easily to changing patterns of diagnosis and therapy. Modern cross-sectional imaging methods, such as multidetector-row computed tomography (MDCT), and magnetic resonance imaging (MRI), perform highly in T-staging of local tumor extent and M-staging of distant metastasis. However, both MDCT and MRI perform poorly in N-staging of lymphadenopathy. At present, 18-F-desoxy-glucose positron emission tomography (FDG-PET) appears to be unreliable in the detection of RCC and its metastasis. This overview of current radiological and surgical literature attempts to describe how modern staging systems for RCC are organized, and which radiological and surgical developments currently influence the way in which primary staging and prognosis of RCC depend on one another.

    The Epstein-Barr virus (EBV) is detected in about 10% of gastric carcinoma cases throughout the world. In EBV-associated gastric carcinoma, all tumor cells harbor the clonal EBV genome. Gastric carcinoma associated with EBV has distinct clinicopathological features, occurs predominately in men and in younger-aged individuals, and presents a generally diffuse histological type. Most cases of EBV-associated gastric carcinoma exhibit a histology rich in lymphocyte infiltration. The immunological reactiveness in the host may represent a relatively preferable prognosis in EBV-positive cases. This fact highlights the important role of EBV in the development of EBV-associated gastric carcinoma. We have clearly proved direct infection of human gastric epithelialcells by EBV. The infection was achieved by using a recombinant EBV. Promotion of growth by EBV infection was observed in the cells. Considerable data suggest that EBV may directly contribute to the development of EBV-associated GC. This tumor-promoting effect seems to involve multiple mechanisms, because EBV affects several host proteins and pathways that normally promote apoptosis and regulate cell proliferation.

    Nine dogs were diagnosed with cranial mediastinal carcinomas. Based on histological and immunohistochemical analysis, four dogs were diagnosed with ectopic follicular cell thyroid carcinomas, one dog with ectopic medullary cell thyroid carcinoma, two dogs with neuroendocrine carcinomas and two dogs with anaplastic carcinomas. Clinical signs and physical examination findings were associated with a space-occupying mass, although one dog was diagnosed with functional hyperthyroidism. Surgical resection was attempted in eight dogs. The cranial mediastinal mass was invasive either into the heart or into the cranial vena cava in three dogs. Resection was complete in six dogs and unresectable in two dogs. All dogs survived surgery, but four dogs developed pulmonary thromboembolism and two dogs died of respiratory complications postoperatively. Adjunctive therapies included pre-operative radiation therapy (n=1) and postoperative chemotherapy (n=3). Three dogs had metastasis at the time of diagnosis, but none developed metastasis following surgery. The overall median survival time was 243 days. Local invasion, pleural effusion and metastasis did not have a negative impact on survival time in this small case series.

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    - Basal cell carcinoma (BCC) is the most common human malignant neoplasm and is a frequently encountered diagnosis in dermatopathology. Although BCC may be locally destructive, it rarely metastasizes. Many diagnostic entities display morphologic and immunophenotypic overlap with BCC, including nonneoplastic processes, such as follicular induction over dermatofibroma; benign follicular tumors, such as trichoblastoma, trichoepithelioma, or basaloid follicular hamartoma; and malignant tumors, such as sebaceous carcinoma or Merkel cell carcinoma. Thus, misdiagnosis has significant potential to result in overtreatment or undertreatment. - To review key features distinguishing BCC from histologic mimics, including current evidence regarding immunohistochemical markers useful for that distinction. - Review of pertinent literature on BCC immunohistochemistry and differential diagnosis. - In most cases, BCC can be reliably diagnosed by histopathologic features. Immunohistochemistry may provide useful ancillary data in certain cases. Awareness of potential mimics is critical to avoid misdiagnosis and resulting inappropriate management.

    NUT carcinoma (NC) is a recently described, rare and extremely aggressive cancer primarily located to supradiaphragmatic structures and affecting young individuals. NC is characterized by translocations involving the NUT gene on 15q14 with the most common translocation partner gene being BRD4 on 19......p13, resulting in the t(15;19)(q14;p13) karyotype. NC is poorly differentiated and is likely to be overlooked and misdiagnosed as poorly differentiated squamous cell carcinoma (SCC) when immunohistochemical evaluation of NUT protein expression is omitted. Previously, NC has been found in the parotid...... and submandibular glands and we present the first case in the sublingual gland arising in a 40-year-old woman.

    A 66-year-old man visited author's institute complaining of the swelling on the submandibular gland area. Clinically, the exophytic mass penetrated the skin of the submandibular area. On MRI, the lesion occupied the left submandibular space and extended downward, protruding exterior to the subcutaneous fat layer, but the center of the lesion was located on the side of the skin and the growth exterior to the skin was prominent. Demarcation of the lesion and the submandibular gland was unclear. Histopathologically the epithelial nests and keratin production were seen, then the biopsy result was squamous cell carcinoma. The stroma of lesion showed a myxoid characteristic and some ducts showed metaplasia of the ductal cells, which suggested the gland-origin carcinoma. However, lots of keratin production and carcinomatous change of cells continuous to the normal epithelium of the skin, the skin-origin carcinoma invading into the submandibular gland area could not be excluded.

    Parathyroid carcinoma is a rare endocrine malignancy accounting for 0.5% to 4.0% of all cases of hyperparathyroidism and commonly present as hypercalcemia and parathyroid hormone (PTH) elevation. Nonfunctional parathyroid carcinoma does not show symptoms of hyperparathyroidism and only showed a vague indication of being pathologic, even when detected late. The optimal treatment is en bloc resection of the cancer, but frequent local recurrence after surgery has been reported. Adjuvant local treatment such as radiotherapy may improve the likelihood local control in cases with incompletely resected or microscopic residual tumor. The results of this study point to a case of nonfunctional parathyroid carcinoma treated by external beam radiotherapy after en-bloc resection of cancer.

    Full Text Available Male breast cancer is rare as compared to female counterpart. Pure mucinous carcinoma is an extremely rare histological subtype representing less than 1% of male breast cancers. So far very few cases of pure mucinous carcinoma of male breast have been reported in the literature, most of which were diagnosed after surgical resection. Fine-needle aspiration cytology is a well-established procedure for the evaluation of female breast masses but the diagnosis of malignancy in aspirates from male breast masses is rare. We herein present one case of mucinous carcinoma of breast in a 75-year-old male diagnosed by fine-needle aspiration and confirmed by histopathology. After a follow-up of 12 months the patient is free of any recurrence or metastasis.

    The ultimobranchial bodies in human embryos develop from the fourth and fifth branchial pouch complexes along with thymic and parathyroid tissue. They become incorporated within the lateral thyroid lobes and are believed to be involved in the development of C-cells. We report a case of an unusual bilateral thyroid and neck prelaryngeal medullary carcinoma in a 23-year-old male patient who belongs to a multiple endocrine neoplasia type 2a (MEN type 2a) family with thyroid tumors and pheochromocytomas. The medullary carcinoma was located in an abnormal cystic structure that seems to be a remnant of the ultimobranchial body (UBB) in the neck. Within the contralateral thyroid lobe, the medullary carcinoma was associated with C-cell hyperplasia.

    Full Text Available The authors report a case of mucinous carcinoma of the male breast firstly diagnosed as a mucinous carcinoma of the skin. The immunohistochemical results of this tumor were as follows: cytokeratin7 (-, gross cystic disease fluid protein 15 (-, p63 (-, estrogen receptor (+, and progesterone receptor (+ for the primary nodule; cytokeratin7 (-, thyroid transcription factor-1 (-, gross cystic disease fluid protein 15 (-, p63 (-, cytokeratin8 (+, cytokeratin18 (+, and cytokeratin20 (+ for the recurrent nodule. The tumor cells had cytokeratin7 (-/ cytokeratin20 (+ phenotype and it was very unusual for mucinous carcinoma of the breast.

    Full Text Available Carcinoma cuniculatum is an uncommon variation of squamous cell carcinoma (SCC has been documented in a few cases at various locations of the body such as penis, foot, jaw, oropharynx and esophagus. In this case, a 79-year-old male presents with a penile mass, which he underwent a total penectomy. Histology of the mass was defined as carcinoma cuniculatum with negative margins and no lymphovascular invasion. This variant of SCC rarely metastasizes. A joint decision was made to observe lymph nodes. It is important to differentiate the different SCC because patient care can be guided based on the pathology.

    Laryngeal carcinoma is usually encountered in smoker men, and thyroid carcinoma is sometimes discovered incidentally during treatment for these patients. However, this coexistence of malignancies could occur in non-smoker female. We report an unusual case of multiple primary malignancies in the larynx and the thyroid gland. The laryngeal carcinoma was suspected to be related to the malignant transformation of the papillomas. The case suggests the importance of meticulous examination in the head and neck region for treatment of cervical metastatic lymph nodes with negative cytology in non-smoker female.

    Hepatocellular carcinoma (HCC) has a very poor prognosis and any effort to identify additional risk factors, besides those already established, would be important for the prevention of the disease. Data on the role of diet on HCC risk are still controversial. We have evaluated the association of adherence to the Mediterranean diet with HCC risk, as well as the interaction of this dietary pattern with chronic hepatitis infection, by combining two case-control studies undertaken in Italy and Greece, including overall 518 cases of HCC and 772 controls. Adherence to the traditional Mediterranean diet was assessed through the Mediterranean diet score (MDS), which ranges between 0 (lowest adherence) and 9 (highest adherence). Odds ratios (OR) for HCC were obtained through multiple logistic regression models, controlling for potentially confounding factors, including chronic infection with hepatitis B/C viruses. Compared to MDS of 0-3, the ORs for HCC were 0.66 (95% confidence interval (CI), 0.41-1.04) for MDS equal to 4 and 0.51 (95% CI, 0.34-0.75) for MDS ⩾ 5, with a significant trend (pMediterranean diet on HCC risk was disproportionally high among those chronically infected with hepatitis B and/or C viruses, with a suggestion of super-additive interaction, albeit statistically non-significant. Closer adherence to the Mediterranean diet appears to be protective against HCC. Our results also point to potential benefits from adhering to a Mediterranean dietary pattern for patients chronically infected with hepatitis viruses.

    Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified. The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient at-risk for developing HCC. The diagnosis of HCC can be based on non-invasive criteria (only in cirrhotic patient) or pathology. Accurately staging patients is essential to oncology practice. The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function. Treatment allocation is based on several factors: Liver function, size and number of tumours, macrovascular invasion or extrahepatic spread. The recommendations in terms of selection for different treatment strategies must be based on evidence-based data. Resection, liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates. Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment. Finally, in patients with advanced HCC with preserved liver function, sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

  10. Hepatitis C and hepatocellular carcinoma.

    Chronic hepatitis C virus infection is a well-recognized risk factor for occurrence of hepatocellular carcinoma (HCC). In Europe, Oceania and America, chronic hepatitis C and alcoholic cirrhosis are the main risk factors for HCC. In Latin America, a few retrospective and one prospective study have also shown the predominant role played by hepatitis C in this setting. Furthermore, the incidence of HCC has been increasing in industrialized countries in the last decades; partially as a consequence of the increase in HCV-related cirrhosis (as the long-term sequel of the peak of infections occurring 2-4 decades ago). The main risk factor for HCC development in patients with hepatitis C is the presence of cirrhosis. Among patients with hepatitis C and cirrhosis, the annual incidence rate of HCC ranges between 1-8%, being higher in Japan (4-8%) intermediate in Italy (2-4%) and lower in USA (1.4%). Some studies have also found that HCC may be the first complication to develop and the more frequent cause of death in the compensated HCV-associated cirrhosis. Other risk factors for HCC occurrence are older age at infection, male gender, decreased platelet count, esophageal varices, presence of porphyria cutanea tarda, liver steatosis or diabetes, infection with genotype 1b, coinfection with hepatitis B virus or with HIV and chronic alcoholism. Many studies and also meta-analysis have reported that antiviral therapy based on interferon may reduce the incidence of HCC in chronic hepatitis C, especially in patients with sustained virologic response. Patients with HCV-related cirrhosis should undergo surveillance for HCC.

  11. Synchronous Parathyroid and Papillary Thyroid Carcinoma

    Full Text Available Concomitant thyroid disease is not unusual among patients with primary hyperparathyroidism. However, the simultaneous occurrence of parathyroid and thyroid carcinoma is extremely rare. We report a 38-year-old man with primary hyperparathyroidism who presented with osteitis fibrosa cystica complicated with pathologic femoral neck fracture. Preoperative investigation for exclusion of multiple endocrine neoplasia did not find evidence of medullary thyroid carcinoma or pheochromocytoma, but imaging studies revealed the presence of nodules in the right lobe and a parathyroid lesion over the left inferior pole of the thyroid gland. Total thyroidectomy, left parathyroidectomy, and bipolar hemiarthroplasty of the left hip were then performed simultaneously. The resected specimens were pathologically identified as papillary thyroid carcinoma and parathyroid carcinoma, respectively. After the operation, 131I ablation therapy was administered at a dose of 120 mCi. Additional doses of 30 mCi were given yearly as serum thyroglobulin level became elevated. Serum calcium level remained normal during yearly follow-up. Although parathyroid carcinoma is an uncommon cause of parathyroid hormone-dependent hypercalcemia, it should nonetheless be given due consideration because its surgical approach differs from that of parathyroid adenoma. As the coexistence of parathyroid and non-medullary thyroid carcinoma has previously been reported, the possibility of both malignancies must also be considered in the setting of primary hyperparathyroidism with thyroid nodules. If confirmed with preoperative parathyroid scintigraphic and other laboratory studies, an optimal outcome may be achieved with complete resection of both tumors at the time of initial operation, followed by adjunctive therapy.

    Background Mucinous carcinoma of the breast is an indolent tumors with a favorable prognosis; however, micropapillary features tend to lead to aggressive behavior. Thus, mucinous carcinoma and micropapillary carcinoma exhibit contrasting biologic behaviors. Here, we review invasive mucinous carcinoma with a focus on micropapillary features and correlations with clinicopathological factors. Methods A total of 64 patients with invasive breast cancer with mucinous or micropapillary features were enrolled in the study. Of 36 pure mucinous carcinomas, 17 (47.2%) had micropapillary features and were termed mucinous carcinoma with micropapillary features (MUMPC), and 19 (52.8%) had no micropapillary features and were termed mucinous carcinoma without micropapillary features. MUMPC were compared with 15 invasive micropapillary carcinomas (IMPC) and 13 invasive ductal and micropapillary carcinomas (IDMPC). Results The clinicopathological factors of pure mucinous carcinoma and MUMPC were not significantly different. In contrast to IMPC and IDMPC, MUMPC had a low nuclear grade, lower mitotic rate, higher expression of hormone receptors, negative human epidermal growth factor receptor 2 (HER2) status, lower Ki-67 proliferating index, and less frequent lymph node metastasis (p HER2, T-stage, and lymph node metastasis were significant risk factors for overall survival; however, only T-stage remained significant in a multivariate analysis (p mucinous carcinoma does not contribute to aggressive behavior. However, further analysis of a larger series of patients is required to clarify the prognostic significance of micropapillary patterns in mucinous carcinoma of the breast. PMID:28597867

    Full Text Available Salivary duct carcinoma is a rare high-grade neoplasm that more frequently affects the parotid gland. Though neoplasms of this type are infrequent in minor salivary glands, they are less aggressive and may lead to early diagnosis before distant metastases could occur. Salivary duct carcinoma is also the most frequent epithelial component of carcinosarcoma. The present article reports a case of SDC of the palate in a 26-year-old male and discusses SDC as a malignant epithelial component in carcinosarcoma.

    2011-02-01

    Full Text Available Abstract Ameloblastic carcinomas are rare odontogenic tumors. Treatment usually consists of surgical resection and sometimes adjuvant radiation. We report the case of a 71 year-old male patient undergoing carbon ion therapy for extensive local relapse of ameloblastic carcinoma. Treatment outcome was favourable with a complete remission at 6 weeks post completion of radiotherapy while RT-treatment itself was tolerated well with only mild side effects. High dose radiation hence is a potential alternative for patients unfit or unwilling to undergo extensive surgery or in cases when only a subtotal resection is planned or the resection is mutilating.

  17. Inflammatory carcinoma of breast: The chameleon

    2017-01-01

    Full Text Available Inflammatory breast carcinoma is an extremely rare, rapidly progressive breast carcinoma which is a great masquerader and often is mistaken as an inflammatory lesion. This leads to the delay in diagnosis. Here, we report such a case where the mistaken clinical diagnosis led to it being treated with antibiotics. However, fine-needle aspiration cytology of the case saved the day. Histopathological confirmation followed by multimodal therapy was rendered, and the patient responded well to the treatment. Thus, awareness and recognition of this rare entity, which mimics various inflammatory and nonmalignant causes, is of paramount importance for the doctors and patients alike.

    With the rising incidence of chronic liver disease caused by viral hepatitis, hepatocellular carcinoma is showing a corresponding rise worldwide. Surgery remains the mainstay of treatment, but patients unfit for surgery or liver transplantation form the bulk of those presenting with this disease. Palliative treatments are being used to treat those and radiological modalities form the mainstay of the treatment. Radiology plays a major role in the diagnosis, treatment and follow-up of hepatocellular carcinoma. Current radiological treatment modalities include percutaneous ethanol ablation, radiofrequency ablation and trans-arterial chemoembolization. This update highlights the recent advancements in the field and compares their relative merits and demerits.

    Full Text Available Collecting duct carcinoma (CDC is a rare, highly aggressive malignant neoplasm that arises from the collecting duct epithelium of the kidney. CDC was reported to coexist with renal cell and transitional cell carcinomas. We report a rare case of CDC associated with oncocytoma, confirmed by the characteristic histological appearance and immunohistochemistry. We also review the epidemiological, histological and immunohistochemical criteria for diagnosis, in addition to the genetic and cytogenetic aberrations reported in the literature. Identification and reporting CDC is important for the establishment of treatment strategies and monitoring prognosis.

    Full Text Available Michael C Kew Department of Medicine, Groote Schuur Hospital and University of Cape Town, Cape Town, South Africa Abstract: Hepatocellular carcinoma is one of the major malignant tumors in the world today. The number of new cases of the tumor increases year by year, and hepatocellular carcinoma almost always runs a fulminant course and carries an especially grave prognosis. It has a low resectability rate and a high recurrence rate after surgical intervention, and responds poorly to anticancer drugs and radiotherapy. Hepatocellular carcinoma does not have a uniform geographical distribution: rather, very high incidences occur in Eastern and Southeastern Asia and in sub-Saharan Black Africans. In these regions and populations, the tumor shows a distinct shift in age distribution toward the younger ages, seen to greatest extent in sub-Saharan Black Africans. In all populations, males are more commonly affected. The most common risk factors for hepatocellular carcinoma in resource-poor populations with a high incidence of the tumor are chronic hepatitis B virus infection and dietary exposure to the fungal hepatocarcinogen aflatoxin B1. These two causative agents act either singly or synergistically. Both the viral infection and exposure to the fungus occur from early childhood, and the tumor typically presents at an early age. Chronic hepatitis C virus infection is an important cause of hepatocellular carcinoma in resource-rich countries with a low incidence of the tumor. The infection is acquired in adulthood and hepatocellular carcinoma occurs later than it does with hepatitis B virus-induced tumors. In recent years, obesity and the metabolic syndrome have increased markedly in incidence and importance as a cause of hepatocellular carcinoma in some resource-rich regions. Chronic alcohol abuse remains an important risk factor for malignant transformation of hepatocytes, frequently in association with alcohol-induced cirrhosis. Excessive iron

    2014-01-01

    Full Text Available A woman in her mid-60s presented with a bulky mass on the anterior abdominal wall. She had a previous incidental diagnosis of endometrial adenocarcinoma FIGO stage IB following a vaginal hysterectomy. Physical exam and imaging revealed a well circumscribed bulging tumour at the umbilical region, measuring 10 × 9 × 9 cm, with overlying intact skin and subcutaneous tissue. Surgical resection was undertaken, and histological examination showed features of endometrial carcinoma. She began chemotherapy and is alive with no signs of recurrent disease one year after surgery. This case brings up to light an atypical location of a solitary metastasis of endometrial carcinoma.

    To determine the efficacy of adipophilin immunohistochemistry in the diagnosis of sebaceous carcinoma of the ocular adnexal region and to provide the guidelines for interpretation of this immunostain. Retrospective, histopathologic case series. A total of 25 patients with sebaceous carcinoma, 21 patients with basal cell carcinoma, 22 patients with conjunctival squamous cell carcinoma, 9 patients with cutaneous squamous cell carcinoma, and 5 patients with conjunctival mucoepidermoid carcinoma. Immunohistochemical staining for adipophilin was performed on paraffin-embedded tissues and correlated with hematoxylin-eosin, periodic acid-Schiff (PAS), and mucicarmine-stained preparations. Immunostaining was quantified by light microscopy and with a computerized image analysis system of scanned images. Statistical analysis was performed to compare immunostaining patterns within the tumor categories by stage and grade, between the different neoplasms, and for correlation between light microscopy observations and computerized image analysis. Localization of adipophilin immunostain, intensity of immunostaining, percent of immunoreactive cells, percentages of vacuolar staining and granular staining, and vacuole size. Adipophilin expression was observed in 100% of sebaceous carcinomas, 100% of cutaneous squamous cell carcinomas, 95% of basal cell carcinomas, 73% of conjunctival squamous cell carcinomas, and 60% of mucoepidermoid carcinomas. Sebaceous carcinomas demonstrated significantly stronger adipophilin expression, a greater number of intracytoplasmic vacuoles, and larger vacuoles. The specificity and sensitivity of adipophilin immunostaining in the diagnosis of sebaceous carcinoma were both 100% when more than 5% of the staining occurred in vacuoles (carcinomas, the pattern and intensity of adipophilin immunostaining are helpful in distinguishing sebaceous carcinoma from other neoplasms with overlapping histology.

    Full Text Available Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

    Approximately 100 cases of collecting duct carcinoma have been reported in the medical literature. We herein report on a case of collecting duct carcinoma of the kidney in a 75-year-old patient. The abdominal sonography depicted a relatively poorly defined 7x6 cm sized, isoechoic mass lesion, as compared to the normal parenchyma, at the left kidney lower pole and the affected kidney showed preservation of the reniform shape. CT revealed a heterogeneous poorly defined low-attenuation mass that was mainly located in the medulla with involvement of the cortex and the lower half of the renal pelvis. Retrograde ureter opyelography showed a filling defect at the lower renal pelvis and severe narrowing of the left proximal ureter. We initially thought this lesion was invasive transitional cell carcinoma. Subsequent surgery confirmed a collecting duct carcinoma

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that has morphologic features similar to secretory carcinoma of the breast and that also harbors the same ETV6 translocation. Diffuse mammaglobin and S-100 immunoreactivity are used to differentiate MASC from its morphologic mimics, especially acinic cell carcinoma and adenocarcinoma, not otherwise specified. However, the combination of mammaglobin and S-100 immunoreactivity has not been well studied in other types of salivary gland carcinomas that may have focal areas reminiscent of MASC. Here we evaluated mammaglobin and S-100 immunoreactivity in 15 cases each of polymorphous low-grade adenocarcinoma, adenoid cystic carcinoma and mucoepidermoid carcinoma, and also in 2 cases of adenocarcinoma, not otherwise specified, and 1 mucinous adenocarcinoma. Cases with significant co-expression of mammaglobin and S-100 (moderate or strong immunoreactivity in >25% of tumor cells) were further analyzed by fluorescence in situ hybridization using the ETV6 (12p13) break-apart probe. Nine cases (60%) of polymorphous low-grade adenocarcinoma and two (13.3%) of adenoid cystic carcinoma met the criteria for significant co-expression of mammaglobin and S-100. All were negative for the ETV6 translocation by fluorescence in situ hybridization. Although mammaglobin and S-100 positivity was seen in the majority of polymorphous low-grade adenocarcinomas and a minority of adenoid cystic carcinomas, none were positive for the ETV6 translocation characteristic of MASC. This indicates a need for caution in the use of immunohistochemistry for diagnosing MASC, especially in the absence of cytogenetic confirmation. © 2013.

    Sebaceous carcinoma is a rare aggressive skin cancer derived from the epithelium of sebaceous glands. Sebaceous carcinomas are generally divided as ocular or extraocular locations. Very few cases of extra ocular sebaceous carcinomas have been reported till date. Among them only six cases were reported which were on the chest wall. We are hereby reporting the seventh case of sebaceous carcinoma on the chest wall. The disease exhibits diverse clinical presentations and histologic patterns, often resulting in a delay in an accurate diagnosis as it may mimic many other cutaneous malignancies like Dermatofibrosarcoma protuberance Basal Cell Carcinoma or Squamous Cell Carcinoma. High degree of suspicion is required and sebaceous carcinoma should be considered as one of the differential diagnosis for an ulceroproliferative growth on the skin.

    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.

    Full Text Available Carcinoma of male breast is uncommon as it accounts for 0.7% of total breast cancer. The pathology of male breast cancer is remarkably similar to that of cancers seen in women. The same histological subtypes of invasive cancer are present, although papillary carcinomas (both invasive and in situ are more common and lobular carcinomas are less common. The predominant histological type, in males, as in females, reported in large series has been infiltrating ductal carcinoma with scattered reports of infiltrating lobular carcinoma, all of them of classical type except for a single case of pleomorphic infiltrating lobular carcinoma. Herein, we describe a case of pleomorphic lobular carcinoma occurring in male breast.

  17. Invasive Lobular Carcinoma Mimicking Papillary Carcinoma: A Report of Three Cases.

    Encapsulated and solid papillary carcinomas (EPCs and SPCs) are considered historically as a special form of ductal carcinoma in situ. Invasive lobular carcinoma (ILC) is characterised by a discohesive growth pattern. There are several variants of ILC, but, as yet, no papillary subtype has been identified. Here we report 3 cases of ILC presenting as papillary carcinoma (PC) with a typical solid papillary growth pattern. One case was reported on core biopsy as EPC (B5a). The 3 ensuing resection specimens showed features typical of SPC with a circumscribed malignant epithelial proliferation containing fibrovascular cores and surrounded, at least focally, by a thick fibrous capsule. The lobular nature of these tumours was confirmed on the resection specimens by the absence of E-cadherin and β-catenin membrane expression. The invasive nature was confirmed by the presence of entrapped fat cells, the absence of myoepithelial cells and focal merging of the solid papillary areas with classic ILC at the periphery. Of note, 1 case was a recurrent carcinoma without an in situ component. This study provides further evidence that EPC and SPC represent a unique growth pattern of breast carcinomas rather than reflecting the in situ or invasive nature of the tumour, and that ILC can acquire a papillary growth pattern. © 2016 S.

    Thirty-four patients with carcinoma of the vagina were treated by radiotherapy at the Hyogo Medical Center for Adults between April 1965 and May 1990. All patients were treated with a combination of external and intracavitary or interstitial irradiation. Twenty-three patients had squamous cell carcinoma, five had adenocarcinoma and two had malignant melanoma. The five-year survival of patients with squamous cell carcinoma was 70% in Stage I (10 patients), 40% in Stage II (seven patients), 50% in Stage III (three patients) and 0% in Stage IV (three patients). Local control was achieved in 72.7% of the patients with squamous cell carcinoma and 60% of those with adenocarcinoma. However, neither of the malignant melanomas was controlled. Five patients had severe complications that required surgical treatment: severe proctitis and small-bowel perforation, ileus, rectal stenosis, vesicovaginal fistula and small-bowel perforation. Local and pelvic failure was noted in three patients. Patients with previous hysterectomy were more likely to develop serious treatment-related complications. (author).

  15. Targeting Hsp90 in urothelial carcinoma

    Science.gov (United States)

    Skotnicki, Kamil; Landas, Steve; Bratslavsky, Gennady; Bourboulia, Dimitra

    2015-01-01

    Urothelial carcinoma, or transitional cell carcinoma, is the most common urologic malignancy that carries significant morbidity, mortality, recurrence risk and associated health care costs. Despite use of current chemotherapies and immunotherapies, long-term remission in patients with muscle-invasive or metastatic disease remains low, and disease recurrence is common. The molecular chaperone Heat Shock Protein-90 (Hsp90) may offer an ideal treatment target, as it is a critical signaling hub in urothelial carcinoma pathogenesis and potentiates chemoradiation. Preclinical testing with Hsp90 inhibitors has demonstrated reduced proliferation, enhanced apoptosis and synergism with chemotherapies and radiation. Despite promising preclinical data, clinical trials utilizing Hsp90 inhibitors for other malignancies had modest efficacy. Therefore, we propose that Hsp90 inhibition would best serve as an adjuvant treatment in advanced muscle-invasive or metastatic bladder cancers to potentiate other therapies. An overview of bladder cancer biology, current treatments, molecular targeted therapies, and the role for Hsp90 inhibitors in the treatment of urothelial carcinoma is the focus of this review.

    Urachal carcinoma is a rare malignancy of urogenital tract. The objective of this study was to assess the clinical presentation, histopathological findings, treatment and outcome of patients of urachal carcinoma at a tertiary care centre. A retrospective analysis of six cases of urachal carcinoma diagnosed over a period of 7 years from 2005 to 2011 was carried out. All pathologic specimens were reviewed by a single pathologist. Clinical and histological features along with treatment were reviewed and patient follow-up and survival outcome was obtained. The mean age at diagnosis was 36 years. Of the six patients, five were male. The tumor was located in dome in five and dome and anterior wall in one patient. All patients underwent partial cystectomy with bilateral pelvic lymph node dissection. The Sheldon pathologic stage was stage II in 1, IIIA in 2, IVA in 3 cases. Five out of six patients received adjuvant radiotherapy. The mean follow-up period was 37 months. Three out of six were disease free at last follow-up. Urachal carcinomas are rare and usually locally advanced at presentation with a high risk of distant metastases. Surgery is the primary treatment of choice. Adjuvant therapy may decrease the chances of recurrence but it needs to be elucidated by prospective trials.

    This work is a part of a pharmacovigilancy survey. To determine the links between radiation therapy, chemotherapy, nasopharyngeal carcinoma and mesenteric ischemia. A case of 69 year old man with a nasopharyngeal carcinoma, treated by radiation therapy and chemotherapy, who developed a lethal mesenteric ischemia is described. Etiology of mesenteric ischemia was unknown. A review of literature had been made on Pubmed with terms: "Mesenteric ischemia" and cisplatin, 5-FU or fluorouracil, radiation therapy, cancer or neoplasm, "head and neck cancer" or "carcinoma of the nasopharynx. In our case, the origin of the mesenteric ischemia is not atheromatous. Chimiotherapy with 5-fluorouracile and cisplatine, radiation therapy and morphine were suspected. According to literature, responsibility of morphine and radiation therapy is uncertain. In opposition, the 5-FU and the cisplatine can be incriminated. Mesenteric ischemia is an uncommon adverse effect of a treatment with cisplatin and 5-FU. It's the second case of mesenteric ischemia associated with a treatment with 5-FU and cisplatin in a patient with a nasopharyngeal carcinoma. ENT physicians must be aware of this complication.

All patients had undergone diagnostic sonomammography. The imaging findings were identified by experienced breast imagers. Final surgical pathology results were used as the reference standard.Results: Thirty-two women ranging in age from 42 to 63 years old (mean age, 53 years, All had biopsy-proven invasive lobular carcinomas. Common features on mammogram included dense mass followed by architectural distortion; three cases showed breast asymmetry and one case was reported as normal. On ultrasound, common features included solid mass with spiculated margins, posterior shadowing, and perpendicular to the skin.Conclusion: Although no specific features could be linked to invasive lobular carcinoma, care should be directed to subtle signs such as architectural distortion and breast asymmetry in order not to miss any lesions. The combination of mammographic and sonographic helps to decrease the relatively high false negative diagnosis of this type of breast cancer.Keywords: mammography, ultrasound, cancer, breast

    Most prognostic studies in differentiated carcinoma have included a high number of papillary carcinomas and few follicular carcinomas, and not all of their conclusions therefore apply to the latter. To analyze the prognostic factors of follicular thyroid carcinoma. Patients with histological diagnosis of follicular carcinoma who had undergone potentially curative surgery, had no disseminated disease at diagnosis, and had been followed up for at least 5 years. Tumor recurrence was defined as: 1) tumor lesions with cytological analysis suggesting malignancy and/or 2) patients with total thyroidectomy with thyroglobulin levels >2 ng/mL. Clinical, therapeutic, and histological parameters were analyzed to assess prognostic factors. Recurrence was found in 25 (38%) of the 66 study patients during a follow-up period of 99 ± 38 months. Most patients with recurrence (n=20) had increased Tg levels without anatomical location, and were initially treated with radioactive I131. In the remaining 5 cases, surgical excision of the lesion was performed, and three patients required surgery during the follow-up period. Two patients died due to the disease (3%), and two other patients (3%) currently have distant metastases. Mean disease-free interval was 154 ± 14 months, and rates of disease-free patients at 5, 10, 15, and 20 years were 71, 58, 58, and 58% respectively. Clinical factors influencing recurrence included 1) age (p=0.0035); 2) sex (p=0.0114); and 3) cervical pain (p=0.0026). Histological/surgical factors associated with recurrence included 1) infiltration into neighboring structures (p=0.0000); 2) type of carcinoma (p=0.0000); 3) size (p=0.0162); 4) vascular invasion (p=0.0085); and 5) adenopathies (p=0.046). In the multivariate study, cervical pain (p=0.018) and extrathyroid invasion (p=0.045) continued to be significant factors. In follicular carcinoma, rates of disease-free patients are 71% at 5 years and 58% at 10 years, and the main predictive factors are presence

    Prostates obtained at autopsy from black and white males in the United States of America, from Colombians, from Japanese migrants in Hawaii, and from Japanese in Japan (all over 50 years old) were serially step-sectioned and examined microscopically using identical techniques and diagnostic criteria. The age-adjusted overall prevalence of latent carcinoma was significantly higher in US blacks (36.9%), in US whites (34.6%) and in Colombians (31.5%) than in Japanese in Japan (20.5%). There was no significant difference in prevalence between Japanese migrants in Hawaii (25.6%) and Japanese in Japan. When the carcinomas were subdivided into latent infiltrative type (LIT) and latent non-infiltrative type (LNT), the LIT component reflected upon the overall prevalence of latent carcinoma. There was an increase in the overall prevalence of latent carcinoma and in the prevalence of LIT tumors with age in Japanese migrants to Hawaii and in Japanese of Japan but only a suggestive increase in blacks and whites in the United States. There was no significant relation between age and prevalence in Colombia. In LNT tumors, there was no consistent trend related to race or age. The size of LIT tumors was significantly greater than that of LNT tumors in all races or in each decade of total material. There were many large LIT tumors in blacks and whites in the United States. These results suggest that the prevalence of LIT tumors shows a race variation similar to the incidence of clinical carcinoma of the prostate, and that LNT tumors probably remain latent during the individual's life span.

    Full Text Available Background: Carcinoma of breast has become the major public health problem among females in developing as well as developed countries. InNepal it comprises 6% of total cancers cases and often diagnosed at advanced stage. Surgical removal or modified radical mastectomy (MRM is the most commonly used tools for disease management. The objective of this study is to identify the clinical, macroscopic and microscopic features of MRM specimens.Materials and methods: This prospective cross-sectional study was carried out at Department of Pathology, Bhaktapur Cancer Hospital, Bhaktapur, Nepal. Macroscopic and microscopic examination provided the tumor size, stage, grade, lymph node status, lympho-vascular invasion and perineural invasion. Data were collected and analyzed using SPSS 16.Results: The study comprised 112 breast cancer patients of which 109 (97.3% were females and 3 (2.7% were males. Invasive ductal carcinoma no specific type was the most common type of breast carcinoma. (84 cases accounting 75% of total cases. Carcinoma with medullary features was second most common (6 cases comprising 5.4% cases followed by lobular, papillary, apocrine, mucinious and NST mixed types. Grade II tumors were most frequent grade observed in 76.79% cases followed by Grade I (12.50% and Grade III (10.71%.Conclusion: As a conclusion invasive ductal carcinoma was the most common histological type breast cancer and the tumors were found at T2 and N3 stage i.e maximum at grade II. Our study provides prognostic significance of histo-pathological information in breast cancer management.

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland neoplasm that is defined by ETV6-NTRK3 gene fusion. To the best of the authors' knowledge, only rare case reports of the cytopathologic features of MASC have been published to date. A wide variety of archival salivary gland tumors were tested for ETV6 translocation by break-apart fluorescent in situ hybridization. Positive cases with preoperative fine-needle aspiration (FNA) specimens or intraoperative touch preparations were retrieved from the archives of The Johns Hopkins Hospital. All smears were reviewed and the cytologic characteristics were described. Five cases of MASC with cytopathologic material (4 FNA specimens and 1 touch preparation) were identified. The cases occurred in 3 men and 2 women ranging in age from 21 years to 78 years (mean, 52 years). On the cytologic smears, the MASCs were variably cellular and exhibited 2 different architectural patterns: 1) intact tissue fragments with isomorphic cells arranged in a sheet-like or papillary configuration; and 2) dispersed and dissociated cells with a mostly "histiocyte-like" appearance with large cells containing abundant vacuolated cytoplasm. No matrix tissue or stromal spindled cells were present. The cells did not display acinic differentiation in the form of cytoplasmic zymogen granules. In each case, the preoperative FNA correctly identified a neoplasm, and the most frequent diagnostic considerations were acinic cell carcinoma, mucoepidermoid carcinoma, and pleomorphic adenoma. MASC is a newly described salivary gland tumor that should be considered in the differential diagnosis of low-grade salivary gland neoplasms. Its cytologic features overlap considerably with those of other tumors, especially acinic cell carcinoma and mucoepidermoid carcinoma. Copyright © 2013 American Cancer Society.

    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.

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    Classifying intracystic papillary carcinoma under invasive or in situ ductal carcinoma is still a matter of debate. The purpose of this study is to explore the genomic relationship of this tumor to its concurrent invasive ductal carcinoma and ductal carcinoma in situ using array comparative genomic hybridization. Intracystic papillary carcinoma cases were classified into three categories: pure, with concurrent ductal carcinoma in situ, or with concurrent invasive ductal carcinoma. Each component was dissected using laser capture microdissection. DNA was extracted and array comparative genomic hybridization was performed. The test of difference in copy number changes among the three tumors was carried out using CGHMultiArray. Intracystic papillary carcinoma clustered with 4 of 5 concurrent ductal carcinoma in situ cases and with 2 of 2 invasive ductal carcinoma cases. Intracystic papillary carcinoma showed the highest proportions of genome copy number aberration, followed by ductal carcinoma in situ then by invasive ductal carcinoma (p=0.06). Comparing intracystic papillary carcinoma with invasive ductal carcinoma vs. without invasive ductal carcinoma, the former had 11q22.1 to 11q23.3 loss (p=0.031) and chr5 gain (p=0.085) and enriched with matrix metalloproteinase genes. Comparing intracystic papillary carcinoma with ductal carcinoma in situ vs. without ductal carcinoma in situ, the former had gain in 5q35.3 (p=0.041), 8q24.3 (p=0.041), and 21q13.2 to 21q13.31 (p=0.011). Comparing intracystic papillary carcinoma with ductal carcinoma in situ, the latter acquired a group of genes involved in cell adhesion and motility, while intracystic papillary carcinoma differentially expressed genes that are involved in papillary carcinomas of other organs (thyroid and kidney). We conclude that the overall molecular change in intracystic papillary carcinoma is closer to ductal carcinoma in situ than to invasive ductal carcinoma, which may explain the indolent behavior of this

    Sebaceous carcinoma is notorious for masquerading clinically as other benign lesions such as chalazion. A tool to better differentiate between these two conditions would thus be desirable. To examine the potential application of noninvasive meibography in the differential diagnosis of chalazion and sebaceous carcinoma of the eyelid as a retrospective cross-sectional study. Five individuals with chalazion and three patients with sebaceous carcinoma were observed. Noninvasive meibography was performed to visualize the reflectivity and shape of the lesion in each subject. Noninvasive meibographic imaging revealed chalazion as a lesion of overall low reflectivity with small regions of higher reflectivity corresponding to lipid granules. On the other hand, the noninvasive meibography revealed sebaceous carcinoma as a poorly marginated lesion of high reflectivity in the eyelid. Noninvasive meibographic imaging may prove useful for the differential diagnosis of chalazion and sebaceous carcinoma. It may also be informative in definition of the resection area in carcinoma patients.

    2013-02-01

    Full Text Available Background: Warthin tumor- like papillary carcinoma of thyroid is a rare variant of papillary thyroid carcinoma. It is characterized by distinct papillary structures lined by oncocytic tumor cells with nuclear features of papillary carcinoma and marked lymphoplasmocytic infiltrate in the papillary stalks. This tumor derives its name from its resemblance to Warthin tumor of major salivary glands.Case presentation: We report a 54- year- old man presented with bilateral thyroid masses. Histopathological study showed papillary structures lined by cells with eosinophilic granular cytoplasm and ground- glass nuclei with lymphoplasmacytic infiltration of the stalks.Conclusion: Warthin tumor-like papillary thyroid carcinoma could be mistaken for benign lymphoepithelial lesions such as Hashimoto thyroiditis, Hurthle cell tumors and tall cell variant of papillary carcinoma. Follow- up information on the previously reported cases has suggested that these tumors behave similarly to usual papillary carcinoma.

    Hepatocellular carcinoma (HCC) is one of the most recurrent and lethal cancers worldwide. The low survival rate of this particular strain of carcinoma is largely due to the late stages at which it is diagnosed. Tumorigenesis of hepatocellular carcinoma is most frequently detected through ultrasonography, magnetic resonance imaging and computerized tomography scans, however, these methods are poor for detection of early tumor development. This review presents alternative hepatocellular carcinoma detection techniques through the use of protein and enzyme/isozyme biomarkers. The detection methods used to determine the serum levels of α-fetoprotein (AFP), glypican-3 (GPC3), Golgi protein 73 (GP73), α-L-fucosidase (AFU), des-γ-carboxyprothrombin (DCP), γ-glutamyl transferase (GGT) and squamous cell carcinoma antigen (SCCA) are presented and each marker's respective validity in the diagnosis of hepatocellular carcinoma is evaluated.

    Directory of Open Access Journals (Sweden)

    M. C. Álvarez Sánchez

    2014-11-01

    Full Text Available Secondary symptomatic gastrointestinal metastases from lung primary tumor are rare. They can cause a variety of clinical conditions such as perforation, obstruction and bleeding. Intestinal perforations of intestinal metastases have a very poor prognosis. We present a case of a patient with metastatic lung cancer who presents with intestinal perforation and pneumoperitoneum. A 67 year old male, immunosuppressed and smoker is diagnosed with acute abdomen secondary to perforation of a tumor of the terminal ileum, as well as three other similar injuries. Resection and anastomosis. The patient died two months after surgery. The final pathological diagnosis supports epidermoidide poorly differentiated lung carcinoma. It was concluded that given an intestinal perforation in a patient diagnosed with lung carcinoma, it shouldn´t be excluded the metastases origen . Surgery is a purely palliative procedure.

  20. Markers of metastatic carcinoma of breast origin.

    Gown, Allen M; Fulton, Regan S; Kandalaft, Patricia L

    2016-01-01

    This review summarizes the three major breast-associated markers that can be of assistance in evaluating metastatic carcinomas for which a breast primary diagnosis is entertained. These markers include gross cystic disease fluid protein-15 (GCDFP-15), mammaglobin, and GATA3. The first two are cytoplasmic markers that show comparable sensitivities for breast cancer, although relatively few of the published studies have employed the same antibodies against the target molecule, making direct comparisons challenging. GATA3 is a nuclear transcription factor that shows superior sensitivity to GCDFP-15 and mammaglobin. However, the specificity of GATA3 can pose challenges, inasmuch as carcinomas of the bladder and other sites can show significant levels of positivity. Determination of the optimal panel of antibodies employed in a given clinical setting will thus depend on the non-breast tumours included in the differential diagnosis. © 2015 John Wiley & Sons Ltd.

    A 94-year-old woman, who had had a chalazion for a period of 8 months, presented because of thickening of the eyelid with necrosis, madarosis and adenopathy. A 67-year-old woman, previously operated on for a sebaceous carcinoma, presented because of reddening of the conjunctiva and eyelid. Clinical evaluation revealed inflammation of the eyelid and an irregular and erythematous superior bulbar conjunctiva with disruption of the limbal architecture. A sebaceous carcinoma is a tumour which is difficult to diagnose and treat, because it can be patchy and has a tendency to pagetoid dissemination. Diagnosis requires a biopsy of the lesion and mapping of biopsies from the conjunctiva of the eyelid and eyebrow. The subsequent treatment depends on the extent of the tumour, and may involve simple cleavage, topical mitomycin C, radiotherapy or exenteration of the eyebrow.

  2. Metastatic mammary carcinoma in a cow

    Directory of Open Access Journals (Sweden)

    Manoela Marchezan Piva

    Full Text Available ABSTRACT: Mammary gland neoplasms in cattle are rarely observed in the field veterinary diagnostics routine. Therefore, the objective of this study is to report a metastatic mammary carcinoma in a fourteen-year-old Holstein cow in the state of Santa Catarina, Brazil. The animal was diagnosed by the field veterinarian with clinical mastitis that was unresponsive to treatment, and was euthanized due to the poor prognosis. At the necropsy, multiple yellow, firm, and sometimes friable nodules, ranging from 0.1 to 20cm were observed in all mammary glands, lymph nodes, kidneys, spleen, liver, pancreas, mediastinal lymph nodes, heart, and lungs. The final diagnosis of mammary carcinoma was established through the association of clinical, necropsy, histopathological, and immunohistochemical findings. Differential diagnoses included diseases such as bovine tuberculosis and chronic fungal or bacterial mastitis.

    2011-12-01

    In the last decades, rarity of chromosomal rearrangements and fusion genes detected in epithelial cancers in using classical karyotyping led to consider these genomic events as specifically restricted to haematological neoplasia and mesenchymal tumors. Today, gene positioning as well as bio-informatics approaches has enabled identifying in carcinoma various fusion genes subsequent to chromosomal translocations, inversions, or deletions. Thus, gene fusion formation appears as a common mechanism in oncology that concerns most of human cancers, independent of original tissue lineage. At a clinical point of view, applications of fusion genes in terms of diagnosis, prognosis and therapeutics can be envisioned. This review will present current knowledge about fusion genes in common carcinoma (prostate, breast, colon). Following a structural and functional description of various fusion genes so far found in human malignant solid tumors, as well as techniques used for their detection, the review will integrate fusion genes in epithelia oncogenesis general scheme. Finally, promising clinical issues of fusion genes will be surveyed.

    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

    Prior to 2005, the treatment options for metastatic renal cell carcinoma (mRCC) were limited. There has been a proliferation of agents since the introduction of sorafenib, sunitinib, and becavicumab for clinical use in advanced renal cell carcinoma. Recently, four new agents have been approved by the US Food and Drug Administration (FDA) for use in mRCC. These agents come from two unique targeted pathways for RCC, tyrosine kinase inhibitors (TKIs) of vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTOR) inhibitors. This review examines the investigational evolution, phases of development, adverse event profiles, and future directions of pazopanib, axitinib, everolimus, and temsirolimus as well as new novel agents being explored in clinical trials for these targeted pathways.

  6. Radiotherapy for metastatic fibrolamellar hepatocellular carcinoma

    Directory of Open Access Journals (Sweden)

    Justin G. Peacock

    2013-07-01

    Full Text Available Fibrolamellar hepatocellular carcinoma (FLHCC is a rare variant of hepatocellular carcinoma (HCC that commonly affects young individuals without a prior history of liver disease. FLHCC commonly results in a better prognosis than HCC; however, the risk of recurrence and metastatic disease is high. FLHCC is typically treated by primary resection of the tumor with 50-75% cure rates. The use of radiation therapy in FLHCC has not been assessed on its own, and may show some success in a very few reported combination therapy cases. We report on the successful use of radiation therapy in a case of metastatic FLHCC to the lung following primary and secondary resections. Our treatment of the large, metastatic, pulmonary FLHCC tumor with 40 Gy in 10 fractions resulted in an 85.9% tumor volume decrease over six months. This suggests FLHCC may be a radiosensitive tumor and radiotherapy may be valuable in unresectable or metastatic tumors.

    2005-12-01

    A mass that developed in the lung of a 10-year-old mixed-breed dog was pathologically examined. Histopathological examination showed papillary and tubular growth of glandular epithelium-like cells in some areas and growth of squamous cells arranged in nests in other areas, showing coexistence of adenocarcinoma and squamous cell carcinoma in a lung tumour. Immunohistochemical staining with anti-keratin-cytokeratin antibody was strongly positive for cytoplasms in both components. Electron microscopically, the neoplastic cells of the adenocarcinoma component had features of glandular cells, with microvilli, numerous free ribosomes, large round secretory granules and intercellular desmosomes. Non-keratinized squamous cells had tonofilaments and intercellular desmosomes. These findings led to the diagnosis of primary adenosquamous carcinoma, which demonstrates phenotypic profiles characteristic of both epidermal keratinocytes and glandular epithelium.

    An 8-year-old, male, mongrel dog developed severe cough and anorexia and died within 3 months. Autopsy revealed an invasive grayish-white mass in the right kidney and multiple nodules in the lungs, thoracic wall, and spleen. Histologically, the renal mass and the other nodules were mainly composed of papillotubular structures lined by oval-to-polygonal pleomorphic cells. The cells were reactive with DBA, PNA, and UEA-1 lectins and positive for vimentin but negative for CD10 and high molecular weight cytokeratin. Because of its histological, histochemical, and immunohistochemical similarities with human collecting duct carcinoma (CDC), a diagnosis of renal collecting duct carcinoma with pulmonary, thoracic, and splenic metastases was established. To our knowledge, this is the first case report of CDC in animals.

    2017-07-01

    Liver cancer, primarily encompassing hepatocellular carcinoma and intrahepatic cholangiocarcinoma, has become the second leading cause of worldwide cancer-related death during the past two decades. Lymphoepithelioma-like carcinomas (LELCs) are defined as tumors composed of undifferentiated epithelial cells with a prominent lymphoid infiltrate, and can arise in the liver as hepatocellular or cholangiocarcinoma forms. Patients with liver LELC display distinctive demographics and tumor characteristics. LELCs also appear to be associated with strikingly better outcomes compared to typical liver cancers, with 5-year survival rates of 57% to 100% versus 12% to 68%, respectively. Liver LELCs represent a unique model of immune response in liver cancer. Data on LELCs of the liver remain limited, and future comprehensive studies are needed to further elucidate this disease, which could ultimately offer precious insights for immunotherapeutic strategies in liver cancer.

    Full Text Available A 70-year-old female underwent follow-up colonoscopy after colonic polypectomy. The colonoscopy revealed the presence of a 7-mm submucosal tumor in the sigmoid colon. The tumor surface was smooth and covered with normal mucosa. It was diagnosed as a submucosal tumor, and polypectomy was performed. Histopathological examination of the resected specimen revealed moderately to poorly differentiated adenocarcinoma measuring 2 × 5 × 3 mm with marked peritumoral lymphocytic infiltration and lymphoid follicle formation. It was diagnosed as carcinoma with lymphoid stroma (lymphoepithelioma-like carcinoma, SM (1,800 μm, ly2, v0, budding; grade 1. We confirmed the indication for noncurative additional surgical resection and performed laparoscopic sigmoid colectomy. No metastases were observed in the dissected lymph nodes.

    Full Text Available Keratocystic odontogenic tumor (KCOT is still a dilemma in the field of medical science because of its biological behavior and transformation of this benign odontogenic tumor to a carcinomatous type, which is called as odontogenic carcinoma. We are presenting here a case of squamous cell carcinoma occurring in recurrent KCOT of temporal region. The rarity of this article is the location of the lesion which is rarest at temporal region. Malignant transformation of these KCOT′s has been reported only in 15 cases in literature, the majority occurring in jaws but no case reported for lesion of temporal region. The pathogenesis of the tumor, the biologic progression, overall clinical, and histopathological features of this rare malignancy, and its management is reported and discussed.

    Fibrolamellar hepatocellular carcinoma (FLHCC) tumors all carry a deletion of ∼400 kb in chromosome 19, resulting in a fusion of the genes for the heat shock protein, DNAJ (Hsp40) homolog, subfamily B, member 1, DNAJB1, and the catalytic subunit of protein kinase A, PRKACA. The resulting chimeric transcript produces a fusion protein that retains kinase activity. No other recurrent genomic alterations have been identified. Here we characterize the molecular pathogenesis of FLHCC with transcriptome sequencing (RNA sequencing). Differential expression (tumor vs. adjacent normal tissue) was detected for more than 3,500 genes (log2 fold change ≥1, false discovery rate ≤0.01), many of which were distinct from those found in hepatocellular carcinoma. Expression of several known oncogenes, such as ErbB2 and Aurora Kinase A, was increased in tumor samples. These and other dysregulated genes may serve as potential targets for therapeutic intervention. PMID:26489647

    1976-05-01

    Necropsies were performed on 285 consecutively unclaimed Orang Asli bodies from Gombak Orang Asli Hospital during an eight-year period from May 1967 to April 1975. Of the 25 malignant neoplasms, hepatocellular carcinoma was by far the commonest (36%). The nine patients with this neoplasm had coexistant macronodular cirrhosis. There were 20 cases of cirrhosis; 45% of these had coexistant hepatocellular carcinoma. The 53,000 Orang Aslis living in West Malaysia comprise three tribes, the Negrito, Senoi, and Melayu Asli (Proto Malays). The Sinoi appear to have a high predilection for liver cancer, all our nine cases occurring in this group. These aboriginal people live in the jungles where they practice shifting cultivation and maintain their own dietary and social customs. Detailed studies of their dietary habits may provide a clue to the etiology of liver cancer in these people.

    Follicular neoplasms of the thyroid gland include benign follicular adenoma and follicular carcinoma. Currently, a follicular carcinoma cannot be distinguished from a follicular adenoma based on cytologic, sonographic, or clinical features alone. As a result, all patients with a follicular neoplasm should, at minimum, undergo a diagnostic thyroid lobectomy and isthmusectomy. A completion thyroidectomy is necessary for invasive follicular carcinoma. The overall ten-year survival for patients w...

  12. Role of SERPINB3 in hepatocellular carcinoma.

    Science.gov (United States)

    Pontisso, Patrizia

    2014-01-01

    SERPINB3 (formerly known as squamous cell carcinoma antigen-1 or SCCA1) is a member of the family of serine-protease inhibitors. SERPINB3 protects cells from oxidative stress conditions, but in chronic liver damage this serpin may lead to hepatocellular carcinoma through different strategies, including inhibition of apoptosis, induction of epithelial to mesenchymal transition and decrease of desmosomal junctions, cell proliferation and invasiveness. SERPINB3 may also contribute to tumor cell resistance to anti-neoplastic drugs through its binding to the respiratory Complex I, protecting cells from the pro-oxidant action of chemotherapeutic agents. Mechanisms of tumor growth promotion induced by SERPINB3 include the inhibition of intratumor infiltration of natural killer cells, up-regulation of Myc oncogene and the recent identification of this serpin as a Ras-responsive factor. In the liver SERPINB3 and SERPINBB4 isoforms (known as squamous cell carcinoma antigen or SCCA) are undetectable in normal hepatocytes, but their expression progressively increases in chronic liver diseases, dysplastic nodules and hepatocellular carcinoma. High SERPINB3 levels have been recently detected in HCC tissue of patients with early tumor recurrence after surgical resection. In serum SERPINB3/4 isoforms (or SCCA) are detectable bound to IgMs (SCCA-IgM) in the majority of HCV infected patients with HCC and in patients with cirrhosis their levels and/or the progressive increase have been found correlated to the risk of HCC development. Preliminary findings in patients with HCC revealed that SCCA-IgM was predictive of HCC prognosis, since low levels of this biomarker were able to identify HCC patients with long overall and progression-free survival.

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

    Squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the 2 most common cutaneous carcinomas. Molecular profiles predicting metastasis of these cancers have not been identified. Epigenetic profiles of 37 primary cases of cutaneous SCC and BCC were quantified via the Illumina Goldengate Cancer Panel. Differential protein expression by metastatic potential was analyzed in 110 total cases by immunohistochemical (IHC) staining. Unsupervised hierarchical clustering analysis revealed that metastatic BCCs had a methylation profile resembling cutaneous SCCs. Metastatic cutaneous SCCs were found to be hypermethylated at FRZB (median methylation: 46.7% vs 4.7%; p = 4 × 10(-5) ). Metastatic BCCs were found to be hypomethylated at MYCL2 (median methylation: 3.8% vs 83.4%; p = 1.9 × 10(-6) ). Immunohistochemical staining revealed few differences between metastatic and nonmetastatic cancers. Metastatic primary BCCs and cutaneous SCCs had distinct epigenetic profiles when compared to their nonmetastatic counterparts. Epigenetic profiling may prove useful in future diagnosis and prevention of advanced nonmelanoma skin cancers. © 2014 Wiley Periodicals, Inc.

    1984-11-01

    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.

    Full Text Available OBJECTIVE: To assess the occurrence of upper urinary tract urothelial tumors (UUTT in Brazil. MATERIALS AND METHODS: We performed a clinical and histopathologic study of 33 patients who were diagnosed with a malignant neoplasm in the renal pelvis or ureter in the period of 1994 to 2004, in a single institution. RESULTS: Among the patients with upper urinary tract carcinoma, 70% were males and 30% females, with mean age of 65 ± 16 years (ranging from 31 to 91 years. Nineteen patients presented renal pelvis tumor (58%, 9 ureteral tumor (27% and 5 synchronic pelvic and ureteral tumors (15%. Renal pelvis tumors represented 2.8% of all the urothelial neoplasms, and 11.4% of all renal neoplasms treated in the same period. Ureteral tumors represented 1.6% of all the urothelial malignancies surgically managed in these 11 years. Tobacco smoking was the most common risk factor, and analgesic abuse was not reported by those patients. Most carcinomas were high-grade and muscle-invasive. Mean time to diagnosis was 7 months, being hematuria the most common symptom. CONCLUSIONS: A high association was also found between UUTT and bladder urothelial carcinoma. UUTT were mostly seen in men in their seventies and related to a high overall and cancer-related mortality rate. The overall disease-specific survival was 40%, much lower than found in most of the reported series.

    We identified a case of lymphadenopathy of metastatic papillary thyroid carcinoma (PTC) with CD20 expression, which was also expressed by the primary tumor. CD20 expression was identified using immunohistochemistry (IHC) in metastatic PTC biopsy samples from a 58-year-old woman. CD20 expression was initially determined using a CD20-recognizing L26 clone. To validate this phenomenon, we performed IHC with another antibody that recognizes the N-terminus of CD20 and fluorescent double staining using anti-TTF-1 and anti-CD20 antibodies. Taken together, we concluded metastatic PTC expressed CD20. We also examined 21 additional PTC cases and found four more cases that were CD20 positive. Therefore, five of the 22 (23%) cases were positive for CD20. In the positive cases, four cases were classical papillary thyroid carcinoma and one case was a follicular variant of papillary thyroid carcinoma. CD20 is an important target for molecularly targeted therapy for a subset of B-cell lymphomas. Complement-dependent and antibody-dependent cellular cytotoxicities are important effector mechanisms of anti-CD20 therapy. Here, for the first time, we report PTC with expression of CD20. Our findings provide a rationale for treating CD20-positive PTC patients with anti-CD20 therapy. © 2017 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

    An 8-year-old male Irish Terrior dog and a male St. Bernard dog each had a thyroid medullary carcinoma. The first dog was hypocalcemic before removal and with recurrence of the neoplasm. In both dogs the neoplasms were bilateral and microscopic metastases were seen only in the regional lymph nodes. Both neoplasms were characterized by a solid alveolar pattern separated by thin vascular stroma or a linear festoon-like arrangement with thick stroma. The neoplastic cells varied little and were polygonal or round with abundant pale eosinophilic and finely granular cytoplasm. There was little mitotic activity. Both carcinomas contained amyloid. Electron microscopically, the neoplastic cells had moderate nuclear pleomorphism, well developed Golgi complexes, and characteristic membrane-bound electron-dense secretory granules. In some sections, the secretory granule membranes were fused to the cytoplasmic membrane and the granules were in the extracellular space. In one carcinoma there were linear fibrillar structures with an average width of 7.8 nanometers similar to that of amyloid fibrils.

  5. Epstein-Barr virus and nasopharyngeal carcinoma

    2014-01-01

    Since its discovery 50 years ago, Epstein-Barr virus (EBV) has been linked to the development of cancers originating from both lymphoid and epithelial cells. Approximately 95% of the world's population sustains an asymptomatic, life-long infection with EBV. The virus persists in the memory B-cell pool of normal healthy individuals, and any disruption of this interaction results in virus-associated B-cell tumors. The association of EBV with epithelial cell tumors, specifically nasopharyngeal carcinoma (NPC) and EBV-positive gastric carcinoma (EBV-GC), is less clear and is currently thought to be caused by the aberrant establishment of virus latency in epithelial cells that display premalignant genetic changes. Although the precise role of EBV in the carcinogenic process is currently poorly understood, the presence of the virus in all tumor cells provides opportunities for developing novel therapeutic and diagnostic approaches. The study of EBV and its role in carcinomas continues to provide insight into the carcinogenic process that is relevant to a broader understanding of tumor pathogenesis and to the development of targeted cancer therapies.

    The aim of this study was to clarify the characteristics of pancreatic head carcinomas mainly invading the groove between the duodenum and the pancreatic head. Nine patients with pathologically proven pancreatic head carcinomas underwent thin-slice dynamic CT, MR imaging, duodenal endoscopy, and angiography (seven patients). Plate-like masses within the groove region were seen in all cases, which showed hypointensity on T1-weighted images and slight hyperintensity on T2-weighted MR images. The masses appeared hypovascular in the early phase and delayed enhancement in the late phase of dynamic CT and MR imaging. On MR cholangiopancreatography, stenosis of intrapancreatic common bile duct was seen in all patients, whereas stenosis of the main pancreatic duct was seen in only three cases. Endoscopy revealed luminal narrowing of the duodenum in all patients, and duodenal mucosal biopsy demonstrated adenocarcinoma in seven patients. Abdominal arteriography showed serrated encasement of peripancreatic arteries in seven patients who received angiographic examinations. The CT and MR imaging findings of groove pancreatic carcinomas resemble those of groove pancreatitis. Differential diagnosis may be achieved by the pathological diagnosis of a biopsy specimen of the duodenal mucosa and arterial encasement on arteriography. (orig.)

    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.

    A 68-year-old woman was referred to the Oculofacial Plastic and Reconstructive Surgery service for evaluation of a left upper eyelid lesion that was worrisome for carcinoma. The mass measured 8 × 8 mm; it was well-circumscribed, pink, and firm with distortion of the eyelid margin, central ulceration, and loss of the lashes. The patient denied previous surgery or trauma in this area, but she had a history of blepharopigmentation (tattoo eyeliner) of all 4 eyelids approximately 7 years prior. Incisional biopsy revealed inflammatory changes consistent with a localized reaction to the tattoo pigment granules. Local kenalog injection was attempted with improvement of the overall appearance but with persistent deformity including irregularity of the margin and loss of lashes. The persistent abnormal appearance was worrisome for an underlying carcinoma missed on the initial incisional biopsy and prompted a full-thickness wedge resection and reconstruction of the abnormal area. The results of biopsy of the excised tissue confirmed absence of malignant neoplasm and showed changes consistent with tattoo granuloma. Tattoo granuloma of the eyelid should be considered in the differential diagnosis of eyelid lesions worrisome for carcinoma in patients with a history of blepharopigmentation.

    Chronic granulomatous mastitis is known as a benign and relatively rare disorder that is often difficult to differentiate from breast carcinoma. We highlight the case of a 34-year-old woman who had recurrent episodes of right breast swelling and abscess for 8 years. These were proven to be chronic granulomatous mastitis by tissue biopsies on 3 different occasions. Her condition improved on similar courses of antibiotics and high-dose prednisolone. However, she subsequently developed progressive loss of vision due to an orbital tumour. She then underwent a craniotomy and left orbital decompression with excision of the tumour, which proved to be a metastatic carcinoma. A trucut biopsy of the right breast was then done and showed features consistent with an infiltrating ductal carcinoma. This case illustrates the possibility that chronic granulomatous mastitis could be a precursor for malignancy and the difficulty in differentiating one from the other. The possible mechanisms of development and the implications for future management are also discussed.

    Full Text Available Objective: To perform a retrospective review of 14 patientssubmitted to surgical treatment of hepatocellular carcinoma atthe Universidade Federal de Sao Paulo – UNIFESP. Methods:Review of data obtained from 14 patients with hepatocellularcarcinoma submitted to surgical resection in the Discipline ofSurgical Gastroenterology, at the Universidade Federal de SaoPaulo - Escola Paulista de Medicina, from June 1992 to September1998. Results: Three patients (21.4% were female and 11 (78.6%were male. Ten patients (71.4% had disease-related symptoms;76.8% were classified as Child-Pugh A. Alpha-fetoprotein levelswere analyzed in 13 patients and were elevated in 65.1%. Allpatients had abdominal ultrasound and computerized tomographyscans compatible with hepatocellular carcinoma. Surgicalresections varied from segmetectomy to trisegmentectomy.Bleeding was the most common intraoperative complication andcaused one death. The most frequent postoperative complicationwas ascitis, followed by pleural effusion, encephalopathy and biliaryfistula. Tumor recurrence rate was 61.5% at one year and wasrelated to tumors larger than 5 cm, tumor invasion and absence ofa capsule, suggesting late diagnosis. Mean disease-free survivalrate was 17 months and mean survival rate was 21 months.Conclusion: The patients with hepatocellular carcinoma submittedto surgical resection had a high recurrence rate in a one-yearfollow-up, probably due to large tumor size, vascular invasion andabsence of a capsule. The importance of an early diagnosis isemphasized.

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor characterized by ETV6 translocation. It appears that prior studies have identified MASC by reviewing salivary gland carcinomas, such as acinic cell carcinoma and adenocarcinoma, not otherwise specified. To address the possibility of MASC mimicking benign salivary neoplasms we reviewed 12 salivary gland (cyst)adenomas diagnosed prior to the discovery of MASC. One encapsulated (cyst)adenoma of the parotid gland demonstrated features of MASC. The diagnosis was confirmed by fluorescence in situ hybridization with an ETV6 break-apart probe. An unusual complex pattern of ETV6 rearrangement with duplication of the telomeric/distal ETV6 probe was identified. This case illustrates that MASC may mimic salivary (cyst)adenomas. To more accurately assess true clinical and morphologic spectrum of MASC, future studies may have to include review of salivary (cyst)adenomas. The differential diagnosis of MASC may have to be expanded to include cases resembling salivary (cyst)adenomas.

    Full Text Available Xp11 translocation renal cell carcinoma (TRCC is a rare subtype of renal cell carcinoma characterized by chromosomal translocations involving the TFE3 gene located at the Xp11.2 locus. Initial cases were more common in children, but cases in older adults have begun to accrue and suggest a relatively more aggressive course. We report a case of Xp11 TRCC in a 63-year-old female patient with initial presentation mimicking upper urinary tract urothelial cell carcinoma, with biopsy proving TRCC. She underwent a radical nephrectomy and paracaval lymph node dissection and is followed up with the intent to initiate vascular endothelial growth factor–targeted therapy in case of recurrence.

  13. An FNA pitfall: Mammary analog secretory carcinoma mistaken for acinic cell carcinoma due to cytoplasmic granules

    2014-12-01

    Full Text Available In the salivary gland, a key differential feature of Mammary analog secretory carcinoma (MASC from acinic cell carcinoma (ACC is the lack of cytoplasmic granules. We report a case of a parotid mass incorrectly diagnosed on fine needle aspirate as acinic cell carcinoma due to many cells with basophilic granules suggesting serous acinar differention. Tumor resection revealed a tumor consistent with low grade adenocarcinoma that had eosinophilic, microvacuolar cytoplasm with distinct basophilic granules staining with PASD and mucicarmine. The diagnosis of MASC was confirmed with stains for GCDF-15, mammoglobin, and S100 and FISH consistent with a t(12;15 translocation. Relying on the absence of cytoplasmic granules as a feature to distinguish ACC from MASC is a diagnostic pitfall.

    Basal cell carcinoma is the most common form of skin cancer, especially in elderly people. Pigmented basal cell carcinoma is a rare subtype and has been described in the literature as a nodular and hyperpigmented lesion; rarely, it can appear as an extensive pigmented plate, which may be clinically indistinguishable from superficial spreading melanoma and Bowen disease. Dermatoscopy has a high sensitivity in the diagnosis of basal cell carcinoma. When Menzies criteria are used; however, the final diagnosis is made by histopathology. The objective of the present report is to analyze the case of a patient with pigmented basal cell carcinoma simulating a superficial spreading melanoma.

    A 64-year-old female patient underwent radical left nephrectomy in 2005 after being diagnosed with renal cell carcinoma. The pathological diagnosis was pT2b pN0 M0 clear cell carcinoma. Three years postoperatively, metastatic recurrence in the para-aortic lymph node was noted, and the patient underwent retroperitoneal lymph node dissection in 2008. The pathological diagnosis was renal cell carcinoma (a combination of clear cell carcinoma and type 2 papillary cell carcinoma). Five years later, she exhibited splenic metastasis on computed tomography, but no other distant metastases were observed. She underwent splenectomy in 2013, and the pathological diagnosis was splenic metastasis of renal cell carcinoma (type 2 papillary cell carcinoma). Three months after the splenectomy, she developed multiple bone metastases but refused to undergo treatment with molecularly targeted drugs ; hence, she was transferred to palliative care services. Fourteen months after the splenectomy, she died of cancer. Most metastatic splenic tumors occur as part of multiple organ metastases in the terminal stage of renal cell carcinoma. If splenic metastasis of renal cell carcinoma is observed, further imaging studies should be performed, and splenectomy should only be considered if a definitive diagnosis of sporadic splenic metastasis is made.

    Full Text Available Reported prostate cancer incidence rates vary greatly among cystoprostatectomy samples. We investigated how the thoroughness of prostate sampling influences prostatic carcinoma incidence in bladder cancer patients. In a retrospective study, 313 cystoprostatectomy cases of urinary bladder carcinoma were analysed for the presence of concurrent prostatic carcinoma. Patients were divided into two groups: patients who had undergone the operation before and after 2007, when a policy of preferably complete prostate sampling in cystoprostatectomy specimens was introduced at our institution. Cases processed after the 2007 recommended sampling changes had a significantly higher rate of incidental prostatic carcinoma and clinically significant prostatic carcinoma than the pre-2007 group (p < 0.0001 and p = 0.003, respectively. Complete prostate processing in cystoprostatectomy specimens results in a higher incidence of incidental prostatic carcinoma than with partial processing. More patients with clinically significant prostate cancer are consequently discovered. In conclusion, we believe that complete prostate sampling should be mandatory.

    Invasive lobular cancer (L) differs clinically and morphologically from invasive ductal cancer (D); differences notwithstanding, Nottingham grades are provided in both. This study compared 22,719 lobular carcinomas with 201,517 ductal carcinomas, dividing them into the grades: well differentiated (W), moderately differentiated (M), poorly differentiated (P), and ungraded to see if differences between comparable grades of lobular and ductal cancer were uniform, consistent with the notion the grading system provides similar information for both cancer subtypes. The Surveillance, Epidemiology and End Results (SEER) database was used to limn relationships among grades, as respects proportions of patients with T3 tumors and nodal metastases, as well as cancer-specific survival. Taken into account were age, estrogen and progesterone receptor status, and the administration of radiotherapy. More lobular than ductal carcinomas were T3; grades were not homogenous, with the incidence rate ratio (IRR) comparing lobular and ductal carcinomas being 8.2 for well differentiated, 4.1 for moderately differentiated, and 2.48 for poorly differentiated. With respect to nodal metastases, the 1.16 W L:W D IRR (P 0.05) and the 0.96 P L:P D IRR (P > 0.05) could have been due to chance. As respects survival, neither the 1.4 P L:P D time ratio (TR) (P 0.05) might have been due to chance. Grades of lobular carcinoma imply different meanings than do grades of ductal carcinoma. Studies of breast cancer should not assume commonality with respect to grade. Copyright © 2011 Elsevier Inc. All rights reserved.
