Up to 5% of all small cell carcinomas develop at extrapulmonary sites. Primary small cell carcinomas originating in the kidney are extremely rare neoplasms. Here we report a case of primary small cell carcinoma of the kidney. A nephrectomy was performed on a 52-year-old female patient to remove a large tumor located in the right kidney. The histology and immunohistochemistry of the resected tum...

Carbonic anhydrase IX (CAIX) is a transmembrane metalloenzyme which upregulated in tumour cells under hypoxic conditions. CAIX expression induced by the accumulation of hypoxia-inducible factor-1α and has several downstream effects, including acidification extracellular pH, loss cellular adhesion increased cell migration. variety solid organ tumours prognostic implications. High protein marker ...

BACKGROUND Renal cell carcinoma commonly metastasizes to lung, liver, and bone. Small intestinal metastases are exceedingly rare. CASE REPORT A 75-year-old man presented at our hospital with tarry stools. He had undergone a right nephrectomy for renal cell carcinoma (RCC) 6 years previously; in addition, he had received antiplatelet treatment for ischemic heart disease. Esophagogastroduodenos...

PURPOSE Elective nephron sparing surgery is established as an alternative to radical nephrectomy for renal cell carcinoma if tumors are small (4 cm or less, stage T1a). We compared outcomes in patients with renal cell carcinoma 4 cm or less (small) vs more than 4 cm (large) who were treated with nephron sparing surgery. MATERIALS AND METHODS Between 1979 and 2006, 618 patients underwent elect...

A 73-year-old female was operated with radical nephrectomy and cholecystectomy for renal cell carcinoma and suspected gallstones after 9 courses of sunitinib treatment. Gallbladder specimen showed gallbladder metastasis originating from the renal cell carcinoma. Gallbladder metastasis from renal cell carcinoma is rare. Here, we discuss a case of gallbladder metastasis from renal cell carcinoma.
