Abstract

A 70-year-old man complained of weight loss (6 kg/6 months), anorexia, and night sweats. He had undergone distal gastrectomy for a duodenal ulcer 30 years previously. Upper gastrointestinal endoscopy revealed a ragged, irregular, and elevated lesion in the remnant stomach. Computed tomography and fluoroscopy revealed a massive tumor, exceeding 10 cm in diameter, in the remnant stomach lumen. A gastrointestinal stromal tumor (GIST) was diagnosed on endoscopic biopsy. The patient had a total remnant gastrectomy with splenectomy and Roux-en-Y reconstruction. On postoperative pathology, GIST with a mitotic index of 10/50 HPFs was demonstrated. The patient is alive without recurrence, 18 months after surgery, and he is receiving adjuvant chemotherapy with imatinib.
