Colonic leiomyoma--an unusual cause of gastrointestinal hemorrhage in childhood. Report of a case.

Leiomyomas of the intestine are rarely found in the pediatric population. The authors' review of the literature revealed only three colonic leiomyomas previously described. The authors present the first reported case of a child with lower gastrointestinal hemorrhage secondary to a colonic leiomyoma. Pathologic aspects of intestinal leiomyomas are discussed along with the difficulty in histologic differentiation from leiomyosarcomas. Wide resection is recommended for spindle cell neoplasms of the intestine owing to difficulty in differentiating benign from malignant tumors.
