%X Se presenta el caso de una mujer joven, que tuvo varios episodios de sangrado digestivo oscuro manifiesto por lo que requiri車 soporte transfusional, realizaci車n de dos esofagogastroduodenoscopias y dos colonoscopias, en las que no se identific車 causa del sangrado. Se realiz車 enteroscopia de doble bal車n encontrando una lesi車n subepitelial, ulcerada, de aspecto neopl芍sico en el 赤leon, la cual se marc車 con tinta china y se tomaron biopsias que no fueron diagn車sticas. Despu谷s de realizar estudios de extensi車n que fueron negativos, se llev車 a laparotom赤a diagn車stica y terap谷utica resecando el segmento de ileon comprometido por la lesi車n y cuyo diagn車stico histopatol車gico y por inmunohistoqu赤mica fue conclusivo de carcinoma neuroendocrino mal diferenciado de alto grado de c谷lula grande. Al final presentamos adem芍s, una revisi車n de sangrado oscuro manifiesto y tumor neuroendocrino de intestino delgado. Young woman who is having episodes of overt obscure gastrointestinal bleeding that requires transfusions. The endoscopic study consists of 2 endoscopies of the upper digestive system and two colonoscopies. The tests do not find the cause of the digestive hemorrhage. A double-balloon enteroscopy is performed and it is found that the Ileum has an ulcerate subepitelial lesion with neoplasic appearance which is marked with Chinese ink and biopsies are taken from the tissue which are not diagnosed. Studies of staging are performed ant the result is negative. A laparatomy is performed for diagnosis and treatment which includes the intestinal resection of ileum where the tumor is placed. The result of the test shows to be a neuroendocrine carcinoma of high degree of large cells undifferentiated. One appears in addition a revision to overt obscure gastrointestinal bleeding and neuroendocrine tumor of small bowel.
