Lymphangioma of bladder.

We report the first case of a lymphangioma arising from the wall of the bladder, protruding into the lumen on 1 side and invading the peritoneal cavity on the other side. The presenting sign was painless macroscopic hematuria that had occurred initially 2 months before hospitalization. Treatment consisted of partial cystectomy. A review of the literature failed to reveal a report of an identical case.
