Primary Small Cell Carcinoma of the Kidney / 대한비뇨기과학회지

ABSTRACT

Small cell carcinoma is a malignant neoplasm, which has neuroendocrine and epithelial features immunohistochemically and ultrastructurally. Primary small cell carcinoma originating from the kidneys is extremely rare, aggressive and lethal. Approximately half the reported cases show combined features of transitional cell carcinoma. A case of primary renal small cell carcinoma without features of transitional cell carcinoma is reported, which was studied under light microscopy and by immunohistochemistry and treated by retroperitoneal laparoscopic radical nephrectomy and chemotherapy.
