Abstract

The mature cystic teratoma of the omentum is a very rare tumor. It is generally believed that autoamputation and reimplantation of an ovarian tumor is the most common etiology of omental teratoma. Abdominal pain is the main presenting symptom of these tumors. A 41-year-old woman was admitted for pelvic mass. At laparotomy, a 8.5 x 7.0 x 7.5 cm mass was found in the pelvic cavity, attached to the omentum with adhesion to bladder. The histopathologic diagnosis was mature cystic teratoma in conjunction with the cyst wall is diffusely necrotic and calcified with hairs. The absence of the left ovary suggested that the tumor underwent autoamputation and reimplantation on the omentum. We report the case with a brief review of literature.
