This paper reports the first described case of pregnancy-associated decidual changes within vesical (urinary bladder) endometriosis that clinically mimicked a rapidly growing bladder tumor. A 36-year-old woman underwent cystoscopy with cold cup biopsy and fulguration of a solitary red-brown nodular bladder lesion, which histologically proved to be decidualized endometriosis. The lesion was managed around delivery, and postdelivery follow-up was uneventful with no recurrence diagnosed. This paper is centrally about endometriosis—specifically pregnancy-induced decidualized urinary bladder endometriosis presenting as a tumor-like lesion.

Abstract

Vesical endometriosis accounts for approximately 1% of all discovered cases of endometriosis. We report the first case of a 36-year-old woman with pregnancy-associated decidual changes within bladder endometriosis that are clinically presented as a rapidly growing bladder tumor. Cystoscopy, with subsequent cold cup biopsy and fulguration, revealed a solitary, red-brown, nodular lesion, which turned to be a decidualized endometriosis of the urinary bladder. Delivery and postdelivery follow-up was uneventful and no recurrence was diagnosed.
