Bladder Endometriosis: A Rare Histopathological Entity Diagnosed by Transurethral Resection.

Bladder endometriosis is a rare form of deep infiltrating endometriosis involving the urinary tract, often presenting with nonspecific urinary or pelvic symptoms and mimicking neoplastic conditions. This report describes a 28-year-old nulliparous female who presented with recurrent pelvic discomfort. Imaging revealed a bladder wall lesion near the vesicoureteric junction, prompting transurethral resection. Histopathological examination facilitated the proper diagnosis. The case highlights the need for a comprehensive diagnostic approach in atypical cases of bladder pathology.
