Primary leiomyosarcoma of the greater omentum: a case report

Abstract

Introduction Greater omentum leiomyosarcomas are rare tumors with only a few cases reported in literature.

Presentation of case We report the case of a 68-year-old man who consulted complaining of diffuse abdominal pain without a palpable mass at physical examination. Imaging studies revealed a solid-cystic lesion in the right lower quadrant. Surgical resection was performed and the tumor was diagnosed as a leiomyoscarcoma by histological and immunohistochemical examinations.

Discussion Surgical resection of all lesions seems to be a reasonable therapeutic approach if resection is feasible. Chemotherapy may be used in selected cases.

Conclusion More cases are needed to define the best treatment approach of this disease.
