[MALIGNANT GASTRIC LEIOMYOBLASTOMA: CASE REPORT]

: The gastric leiomyoblastoma is a benign neoplasia -extremely uncommon and potentially malignant-, which arises from the muscular layer of the stomach. We present the case of a 21 year old male patient with this disease, who suddenly had intraperitoneal hemorrhage. He underwent an exploratory operation and the surgical findings showed an ulcerated and bleeding nodular tumor, located on the anterior wall and minor curvature of the gastric antrum, ulcerated and with active bleeding. A distal subtotal gastrectomy was performed, as well as a Billroth II-type gastroenteroanastomosis from the Hoffmeister-Finsterer variety. The anatomopathologic report was, "malignant gastric leiomyoblastoma". We discuss the clinical features and therapeutical options used.
