Adenocarcinoma of the bladder: a case report

Background: Adenocarcinoma of the urinary bladder is a rare malignancy accounting for 0.5-2.0% of all bladder cancers and has a poor prognosis. The main treatment is radical cystectomy. However, there is no case report of adenocarcinoma of the urinary bladder treated by robot -assisted radical cystectomy. Case Description: A 43 -year -old man was diagnosed with bladder tumor that was incidentally detected during ultrasonography. Cystoscopy revealed a follicular tumor in the trigon of the urinary bladder. The patient underwent transurethral resection and pathological examination revealed adenocarcinoma, not otherwise specified, associated with intestinal metaplasia and cystitis glandularis of the urinary bladder. Most parts of the specimen exhibited intestinal metaplasia and cystitis glandularis. Adenocarcinoma with a nonspecific glandular growth was found in some part of the specimen and the Ki-67 positivity rate was higher in these regions than in the other regions. Computed tomography, gastroscopy and colonoscopy revealed no other tumors. The patient underwent robot -assisted radical cystectomy with a total intracorporeal urinary diversion (ileal neobladder). Pathological examination revealed no residual tumor (pT0). Conclusions: Here, we report a rare case of adenocarcinoma of the urinary bladder associated with intestinal metaplasia and cystitis glandularis of the urinary bladder treated by robot -assisted radical cystectomy. The patient was free from recurrence 1 year after the surgery.
