Oxidized Cellulose (Surgicel???) Granuloma Mimicking a Primary Ovarian Tumor

A 37-year-old woman presented with left lower quadrant pain and vaginal spotting 1 month after hysterectomy and right salpingo-oophorectomy, which were performed for hemoperitoneum related to a ruptured corpus luteum. An 8-cm left ovarian mass was removed that had a microcystic, mucoid sectioned surface. Histological examination revealed that the mass consisted of a massive foreign-body granulomatous reaction to oxidized cellulose (Surgicel). To our knowledge, this is only the second report of an ovarian Surgicel granuloma.
