We report a case of a seventy-year-old gentleman presenting with pain abdomen for 3 days which was sudden in onset, non-radiating, colicky in nature and gradually progressing to diffuse abdominal pain. Emergency chest x-ray (PA view) showed “Gas under Diaphragm” signifying suspicion of intestinal perforation. Exploratory laparotomy showed a thickened segment of jejunum 20 cm from DJ flexure with a perforation at antimesenteric border having a diameter of 2 cm which was resected with 5 cm margin and anastomosed. Histopathological and immunohistochemical examination diagnosed it to be a CD117 (KIT) positive Jejunal (Small Intestinal) Epithelioid GIST with high mitotic count and atypia (pT3N0Mx), with negative resection margins and reactive lymph node hyperplasia. The diagnosis along with its site of presentation and certain peculiarities constitute a rarity.
