We report a case of upper gastrointestinal bleeding caused by a gastrointestinal stromal tumor in a 50-year old man. The patient was having melena for two months, and on admission he was hemodynamically stable. Upper G.I endoscopy showed diffuse gastritis and an extrinsic compressing mass in the upper part of the stomach. CT scan of the abdomen showed exophytic mass in the fundus of the stomach, with central necrosis. The patient was submitted to operative management. There were no features of dissemination but there was invasion of the hilum of the spleen. Wide local resection and splenectomy performed. Post operative course was complicated by a bleeding from the anastomotic site that required re-exploration and suturing of the bleeding vessel. Histologic examination revealed that it was composed of spindle-shaped cells with elongated nuclei. Post operatively the patient received adjuvant treatment with Imatinib [Gleevec]. The patient has an uneventful follow-up period so far.
