ABSTRACT

Objective:To report a case of mature cystic teratoma of the omentum.
Setting:Second-level health care hospital.
Case report:Benign cystic teratomas of the omentum are an extremely rare condition. We report a case of a mature cystic teratoma of the omentum. A 47-year-old woman was evaluated because of a three-month history of increasing abdominal girth and urinary incontinence. Physical examination revealed a non-painful, large, mobile, well-circumscribed abdominal mass. Ultrasonography of the abdomen showed an 8 by 6.5 by 6 cm cystic mass in the right upper abdomen. At surgery through a median laparotomy, a large mass embedded in the tissue of the greater omentum was removed. The tumor consisted of a multiloculated and heterogeneous cystic mass, containing hair and sebaceous material as well as calcifications. Examination by light microscopy revealed a benign germ cells neoplasm, classified as a mature teratoma. The patient was sent home four days after surgery and was asymptomatic at the four-month follow-up visit.
Conclusion:The two most useful diagnostic tools to suspect a teratoma are ultrasonography and computed tomographic scan of the abdomen. Treatment of mature omental teratomas consists of local excision, with partial omentectomy. Postoperative chemotherapy is recommended for immature teratomas due to their high malignant potential.
