 note = {A 75-year-old woman presented at our hospital in June 2000 with hematochezia and abdominal pain which had first developed in April, and she was admitted on July 4. An endoscopic examination of the lower gastrointestinal tract showed a blood flow out of the ileum, and a hemorrhage from the small intestine was suspected. Radiography of the small intestine revealed a protruding hemispherical lesion at a position some 30 cm from the Treitz ligament toward the anus, and it was thus diagnosed to be a tumor of the small intestine. As a result, on July 17, a segmentectomy of the jejunum was performed. Macroscopically, a 5.7 x 4.8 cm well-defined sessil tumor with a flat surface and showing extramural growth was detected in jejunum. A small erosion was present on the mucosal surface. On a histopathological examination, HE staining showed a funicular-formed growth of spindle cells. Immunostaning was positive for CD117 and CD34, and was also partially positive for smooth muscle actin, and negative for s-100. Based on the above findings, a primary gastrointestinal pacemaker cell tumor (GIPACT) of the jejunum was diagnosed. The patient had an uneventful postoperative course, and was discharged on the 22nd postoperative day},
