title: Ureter in histopathologic specimen: a gynecologist's nightmare.
abstract: An 18-year-old woman presented with a large right-sided ovarian cyst. After further evaluation and counselling, the patient underwent laparotomy and oophorectomy. The pathology report described a large mature cystic teratoma with a tubular structure consistent with a cross-section of ureter. Subsequent evaluation of the urinary tract system was normal indicating that the ureter was an element of the mature cystic teratoma.
