[Bellini duct carcinoma of kidney with invasive growth pattern: a case report].
We report a case of Bellini duct carcinoma of the left kidney with invasive growth pattern. A 39-year-old man was admitted to our hospital with the chief complaint of gross hematuria. Ultrasonography showed left renal swelling but normal reniform configuration of the kidney was maintained. Computed tomography demonstrated a low density tumor infiltrating into the renal cortex and with tumor extension into the renal vein. Renal angiography revealed a hypovascular tumor. We suspected a left renal cell carcinoma with tumor extension into the left renal vein, and performed radical nephrectomy. Macroscopically, the resected kidney had a normal outer contour. The tumor with infiltrative growth pattern existed in renal medulla. Histopathologic examination revealed a papillary adenocarcinoma originated in Bellini duct (pT3bN2M0). The patient underwent systemic chemotherapy (M-VAC). This case showed invasive growth pattern, which were different from the usual renal cell carcinoma and Bellini duct carcinoma.
