Primary leiomyosarcoma of the lesser sac--report of a case

Abstract

A case of leiomyosarcoma arising in the lesser sac in a 64-year-old man is presented. A second operation was required because of local recurrence 6 years following the first operation. A review of the literature revealed that only eight cases of leiomyosarcoma arising in the lesser sac, including our case, were reported. Almost all of these patients had symptoms of abdominal pain or distension. The tumor tended to grow to a large size and about 90 percent were over 10 cm in the maximal diameter. The prognosis of these series was poor and our own patient seems to be the second 5 year survivor.
