We studied the expression of the N-myc proto-oncogene and the insulin-like growth factor-II (IGF-II) gene in human fetuses of 16-19 gestational wk. Both genes have specific roles in the growth and differentiation of embryonic tissues, such as the kidney and neural tissue. Since continued expression of N-myc and IGF-II mRNAs is also a characteristic feature of Wilms' tumor, a childhood neoplasm ...
Collecting duct carcinoma (CDC), also known as Bellini duct carcino-ma, is a rare neoplasm comprising less than 1% of renal epithelial tumors [1]. Collecting duct carcinoma is an aggressive neoplasm and is thought to arise from the collecting ducts of renal medulla [2]. Papillary renal cell carcinoma (PRCC) comprises 10% of renal cell carcinomas (RCC) and has distinct cytogenetic and molecular ...
Mucinous tubular and spindle cell carcinoma (MTSCC) is a relatively rare renal epithelial neoplasm. Although MTSCC is considered to be a low-grade and indolent neoplasm, aggressive cases have been recently reported. The present study discussed two additional cases of high-grade MTSCC causing multiple distant metastases with a fatal course. In case 1, a 71-year-old patient presented with hematur...
Cystic lesions of the pancreas are increasingly recognized. While some lesions show benign behaviour (serous cystic neoplasm), others have an unequivocal malignant potential (mucinous cystic neoplasm, branch- and main duct intraductal papillary mucinous neoplasm and solid pseudo-papillary neoplasm). European expert pancreatologists provide updated recommendations: diagnostic computerized tomogr...
Introduction: Solid and cystic papillary epithelial neoplasm of pancreas is a rare neoplasm with low malignant potential which often occurs in young women. The tumor is usually large and encapsulated. Microscopic examination reveals small round cells with papillary-configuration in a delicate vascular stroma. Case Report: The cases presented in this report were 2 women at the age of 15 & 26...
Abdominal computed tomography in a 64 year-old male presenting hematuria showed two malignant tumors in the left kidney, thus radical nephrectomy was realized. In histological preparations a clear cell renal cell carcinoma and a papillary urothelial carcinoma were identified occurring synchronously, which is a rare occurrence having only about 50 cases reported in the literature.
Introduction Pancreatic acinar cell carcinoma (ACC) is a relatively rare neoplasm. Furthermore, tumor rupture extremely rare. Only 1 case of ruptured pancreatic ACC has been reported, and the long-term outcome unknown. Here, we present spontaneously with survival after successful resection. Case Presentation A 67-year-old man was brought to our hospital by ambulance, presenting progressive left...
