title: Rectal and appendiceal inflammatory myofibroblastic tumors.
abstract: Inflammatory myofibroblastic tumors are neoplasms characterized by spindle cell proliferation and a fiboinflammatory vascular stroma. Herein, we presented the successful treatment of a rectal inflammatory myofibroblastic tumor in an 11-year-old boy who presented with diarrhea and abdominal pain of 1(1/2) months duration and an appendiceal inflammatory myofibroblastic tumor in a 29-year-old man presented with recurrent abdominal pain of two months duration with associated tenderness and rebound tenderness in the right lower abdomen. Histologically, our cases had inflammatory myofibroblastic tumors very similar to that of other sites; the spindle cells were positive for vimentin and muscle-specific actin.
