[A case of adenocarcinoma arising in the vesical diverticulum].
A 70-year-old woman presented at our hospital with the chief complaint of gross hematuria and pain on urination. Cystoscopy revealed a broad-based tumor covered with mucus on the right wall of the bladder and therefore a transurethral resection was performed. At surgery the tumor was found to arise from the diverticulum and could not be resected because of the risk of perforation. A histopathological examination disclosed adenocarcinoma including a small region of signet ring cell carcinoma. The tumor was thus diagnosed to be adenocarcinoma originating from the vesical diverticulum and total cystectomy and urinary diversion (ileal conduit) were scheduled. At operation, the carcinoma was found to have infiltrated into the cecum. The operation procedure was therefore changed to partial cystectomy and excision of the cecum in consideration of both the patient's quality of life and her overall prognosis. Although a tumor originating from the vesical diverticulum and adenocarcinoma are both considered to be factors indicating a poor prognosis, no signs of recurrence or metastasis have been detected in this patient at 26 months after the operation.
