KIT expression has not been studied substantially in renal tumors. We analyzed the immunohistochemical expression for KIT in 256 conventional renal cell carcinomas (RCCs), 29 chromophobe RCCs, 25 papillary RCCs, 6 collecting duct RCCs, 6 unclassified RCCs, 7 renal oncocytomas, 20 urothelial carcinomas, 7 nephroblastomas, and 23 angiomyolipomas. We found that 24 chromophobe RCCs (83%) and 5 rena...
Renal cell carcinoma (RCC) is the most common malignant tumor involving the kidney. Determining the subtypes of renal cell carcinoma is among the major goals of preoperative radiological work-up. Among all modalities, magnetic resonance imaging (MRI) has several advantages, such as inherent soft tissue contrast, detection of lipid and blood products, and excellent sensitivity to detect small am...
metastatic tumors in the nose and paranasal sinuses are infrequent. the origin of this metastatic tumors are often renal cell carcinoma. we present one case of metastatic renal cell carcinoma to the nose and paranasal sinuses ,4 years after initial nephrectomy and diagnosis of stage t1n0m0 clear cell carcinoma. the patient complained of nasal obstruction and recurrent epistaxis who was tr...
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,...
UNLABELLED Synchronous occurrence of benign and malignant kidney tumours is very rare. We present the case of a 63-year-old female patient who underwent a bilateral partial nephrectomy after being diagnosed with bilateral kidney tumours by ultrasonography and a computed tomography scan. Histopathological analysis of the left kidney tumour mass revealed a chromophobe renal cell carcinoma. In the...
PURPOSE To compare gene expression profiles of chromophobe renal cell carcinoma (RCC) and benign oncocytoma, aiming at identifying differentially expressed genes. EXPERIMENTAL DESIGN Nine cases each of chromophobe RCC and oncocytoma were analyzed by oligonucleotide microarray. Candidate genes that showed consistent differential expression were validated by reverse transcription-PCR using 25 f...
