Abstract

<p>The patient was a 41-year-old woman who was under follow-up for neurofibromatosis type 1 (NF1) at our orthopedic surgery department. During one of her regular medical checkups, she went into shock, and a blood test revealed a Hb level of 5.8 g/dl. Suspecting gastrointestinal bleeding, we performed esophagogastroduodenoscopy (EGD), which revealed a 20-mm-sized submucosal tumor in the anterior wall of gastric pylorus with a bleeding ulcer over the tumor. Gastrointestinal stromal tumor (GIST) was suspected. After the patient’s general condition stabilized with blood transfusions, we performed laparoscopic surgery. To avoid postoperative gastric outlet obstruction due to cicatricial stricture at the suture site after partial resection, we performed distal gastrectomy. Immunohistochemistry revealed CD34-positive spindle-shaped cells and the tumor was diagnosed as a GIST.</p>
