We report the first case of a pathological complete response for plasmacytoid urothelial carcinoma of the bladder. A 76-year-old man was diagnosed with plasmacytoid urothelial carcinoma (T4, N0, M0) by the microscopically plasmacytoid appearance of the specimen from the transurethral resection. Immunohistochemical studies were positive for epithelial markers and negative for lymphoid markers. Two cycles of systemic chemotherapy were performed with methotrexate, etoposide, vinblastine, and cisplatin, followed by radical cystectomy. The pathological examination revealed no residual cancer cells in the resected specimen.

Our surgical experience with 7 cases of intrarenal vascular malformation is reported. Based on angiographic criteria the so-called congenital arteriovenous fistula of the kidney may be classified either as the cirsoid type, which represents a truly congenital form of arteriovenous malformation, or as the aneurysmal type, which is considered to be idiopathic or spontaneous. These 2 types of arteriovenous malformations are compared with regard to clinical presentation and the choice of surgical treatment for each type is discussed.
