Appendiceal carcinoma invading the urinary bladder.
A case is reported of a 78-year-old woman with appendiceal carcinoma invading the bladder causing irritative symptoms. Although several imaging studies suggested that the secondary bladder tumor was of cecal or appendiceal origin, such as abscess or mucocele, histologic findings on transurethral and transvaginal biopsy were inconclusive. However, following laparotomy, pathologic examination of the frozen sections revealed a mucinous cystadenocarcinoma originating in the appendix and a right hemicolectomy and en bloc partial cystectomy were performed. One year after the operation, the patient was well with no evidence of recurrent cancer.
