A 32-year old woman had recurrent episodes of severe dysuria and lower abdominal pain. Her symptoms recurred despite several courses of urinary antibiotics. She did not have macroscopic haematuria. The physical examination was unremarkable. The urinalysis showed microscopic haematuria and pyuria. The urine culture did not grow any organisms. The abdominal and pelvic ultrasonography was normal. The cystoscopic examination revealed a papillary lesion with bluish patches visible on the surface in the left postero-lateral wall of the bladder. The mucosa was intact over the lesion. Transurethral endoscopic resection of the lesion was done and the histopathology revealed bladder endometriosis (Figures 1, 2 and 3).
