Laparoscopic excision of an omental leiomyoma with a giant cystic component.

Primary tumors of the omentum are uncommon, and leiomyomas arising in the omentum are exceedingly rare. We report on a patient who presented with a large abdominal cyst presumed to be an omental cyst. At laparoscopy, after aspiration, the cyst was found to be attached to a solid mass arising from the greater omentum. The entire tumor was successfully excised laparoscopically. Histopathology and immunohistochemistry revealed it to be an omental leiomyoma with a large degenerative cystic component. Treatment by a minimal access approach allowed the patient to recover rapidly with a short convalescence. Our case confirms the feasibility and safety of a minimal access surgical approach to a rare pathological entity.
