Se denominan tumores del estroma gastrointestinal a los tumores mesenquimales, fusiformes o epitelioides, primarios del tracto digestivo, mesenterio y retroperitoneo (1). Son sarcomas que, en su mayoría, derivan de precursores de las células intersticiales de Cajal, las células marcapasos del tracto gastrointestinal tracto responsable de su motilidad (2) (5). Estos tumores se presentan asintomáticamente en la generalidad de los casos, especialmente en los más pequeños del tracto intestinal, y son diagnosticados incidentalmente durante una exploración endoscópica o imágenes radiológicas por un propósito diferente o durante cirugía (3). Los pacientes sintomáticos pueden mostrar síntomas inespecíficos: náuseas, vómitos, dolor abdominal distensión, saciedad temprana, dolor abdominal y rara vez como masa abdominal palpable (4). Se expone el reporte de caso de mujer de 72 años con antecedentes de hipertensión arterial y anemia, que acude por dolor intenso en epigastrio, tipo urente, acompañado de deposiciones diarreicas en abundante cantidad en concho de café con coágulos. Permanece hospitalizada durante 18 días por hemorragia digestiva alta. Se realiza angiotomografía axial computarizada de aorta abdominal, laparotomia exploratoria más exceresis de hemangioma y resección de yeyuno. Se envió muestra para estudio histopatológico e inmunohistoquímico.
