Vesical adenocarcinoma occurring in patient with pelvic lipomatosis

This is the first case reported of adenocarcinoma of the urinary bladder in a patient with pelvic lipomatosis and cystitis glandularis. The abnormal pelvic fat hampered endoscopic evaluation and transurethral biopsy, confused clinical staging, and complicated preoperative irradiation and cystectomy. The development of adenocarcinoma in this patient indicates the potential for malignant transformation of cystitis glandularis and underscores the necessity for endoscopic follow-up of persons with pelvic lipomatosis.
