We present a case a 74-year-old female patient with gastrointestinal bleeding of obscure origin. Even after complex complementary exams, no definitive diagnosis was possible. Surgical cavity inventory found a pedunculated mass of approximately 10.0 centimeters on its largest axis on the antimesenteric border of the distal ileum. The segment with the lesion was resected, and end-to-end enteroanastomosis was performed in a single plane. Pathologic examination of the mass demonstrated a gastrointestinal stromal tumor. The patient evolved satisfactorily, without evidence of new episodes of gastrointestinal bleeding, and was referred to the clinical oncology service.
