A CASE OF GASTROINTESTINAL STROMAL TUMOR WITH PERFORATION

Abstract

A 59-year-old woman with abdominal pain was diagnosed as having a perforated submucosal stomach tumor (8.0×8.0cm) expanding toward the serosa using abdominal computed tomography. The patient underwent emergency surgery. A histological examination of the resected sample showed palisading spindle cells but little mitosis. The immunohistological findings were positive for CD34 and C-kit, and the lesion was diagnosed as a gastrointestinal stromal tumor of uncertain origin (GIST).
