Gastrointestinal smooth muscle tumors and iron deficiency anemia in children.

Smooth muscle tumors are rarely seen in the pediatric population. We present a child with smooth muscle tumor of low malignant potential in the ileocecal valve region in whom iron deficiency anemia was the only presenting sign. Abdominal computed tomographic (CT) scan, barium enema, and colonoscopy revealed the mass. Following resection of the tumor the anemia was corrected and the child feels well.
