Leiomyoma and Ovarian Cancer

Ovarian cancer is often difficult to diagnose with certainty pre-operatively. This photograph illustrates a not uncommon reason for this difficulty. This patient underwent a hysterectomy and bilateral salpingoophorectomy for “enlarging fibroids”. The uterus does, in fact,, contain a large leiomyoma projecting from the fundus (the white mass at the top of the picture). The right ovary was also found to be completely replaced with a grade 3 adenocarcinoma (the mass on the left of the photograph).
