A case of primary omental leiomyosarcoma / 대한내과학회지

ABSTRACT

Omental leiomyosarcomas are rare intra-abdominal tumors. This report describes a case of primary leiomyosarcoma of the greater omentum. A 76-year-old female complained of palpable abdominal mass which was revealed to be a primary omental tumor by means of UGI, small bowel series, abdominal ultrasonography, and computed tomography. Upon laparotomy, no metastatic focus was found and a part of tumor was found adhered to gastric serosa. Total omentectomy including the mass was performed. Histological examinations of the tumor confirmed a diagnosis of leiomyosarcoma. At 36 months postoperatively, there is no sign of tumor recurrence or metastasis.
