چکیده
Classification The major morphological classifications (WHO/ AFIP; modified Mainz classification, and the Heidelberg classification) discriminate eight sub-types of renal cell tumors related to the basic cell types of the nephron from which they are derived, and in line with the genetic facts as presently understood: 1) metanephric adenoma and metanephric adenofibroma, 2) papillary adenoma, 3) renal oncocytoma, all three benign parenchymal neoplasms Malignant parenchymal neoplasms are: 4) common or conventional (clear cell) renal carcinoma, 5) papillary (formerly chromophilic or tubulopapillary) renal carcinoma, 6) chromophobe renal carcinoma, 7) collecting duct carcinoma, and 8) renal cell carcinoma, unclassified.

Sarcomatoid Chromophobe Renal Cell Carcinoma with Heterologous Component
Clear cellrenal cell carcinoma (RCC) is the most common malignant renal tumor in adults, while chromophobe RCC (CRCC) is the third most common. Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC. Here a61-year male is presented with hematuria and palpable mass. Clinicoradiologically, RCC was considered and left r...
متن کاملIn vivo imaging of cellular proliferation in renal cell carcinoma using 18F-fluorothymidine PET
Objective(s): The ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. The aim of this study was to evaluate the uptake of 18Ffluorothymidine (FLT) PET in renal cell carcinoma (RCC), and to compare this to 18F-fluorodeoxyglucose (FDG), and to an immunohistochemical measure of cellular proliferatio...
متن کاملMetastatic Renal cell Carcinoma Presenting as a clear-cell Tumor in Tongue: A Case Report
Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs,...
متن کاملFeasibility of sentinel lymph node mapping in renal cell carcinoma using intraoperative radiotracer injection
Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...
متن کاملAn Unusual Case Report: Occurrence of Renal Cell Carcinoma, Basal Cell Carcinoma and Chronic Lymphocytic Leukemia in a Case of Papillary Thyroid Carcinoma Treated with Radioactive Iodine
The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinog...
