Bladder wall lipoma

Bladder wall lipoma is a rare finding that includes mature, well-encapsulated fatty tissue within the submucosa of the bladder wall. We present a case of a submucosal bladder wall lipoma that was discovered incidentally during a workup for microhematuria. This lesion was seen during cystoscopy and removed using cold cup biopsy forceps. This lipoma should be differentiated from pelvic lipomatosis in that it was confined to the submucosa of the bladder wall and did not cause compression of the pelvic viscera or its structures.
