Leiomyosarcoma in leiomyomatosis of the small intestine

Abstract
Summary: Multiple leiomyomata of the small intestine are rare. We report one such case where a leiomyosarcoma had arisen from a leiomyoma in the small intestine 8 years after presentation. The possible origin of the leiomyomata is discussed and it is concluded that small intestinal leiomyomatosis should be regarded as a premalignant condition.
