膀胱原発印環細胞癌の1例

Abstract

A 41-year-old man visited our clinic with complaints of gross hematuria and pain on urination. Cystoscopic examination revealed papillary and sessile tumor at the retrotrigone of the bladder and the specimen of the transurethral biopsy showed signet ring cell carcinoma. Since there was no primary tumor in any other organs, we diagnosed it as a primary signet ring cell carcinoma of the bladder. Total cystectomy with Kock continent ileal reservoir and post-operative chemotherapy consisting of cisplatinum, adriamycin and 5-FU were performed. The literature on the pathological findings of this disease are reviewed.
