title: [Gastric leiomyosarcoma].
abstract: We present a case of gastric leiomyosarcoma of special characteristics, given its clinical and pathologic divergence the existence of antecedents of sarcomatous neoplasm previously excised in the same patient. We emphasize the association of these tumors with the appearance of malignant neoplasms in other sites previously, synchronically or metachronically, and the necessary preoperative staging, based fundamentally on CAT and endoscopy, to establish the therapeutic approach according to the predicted behavior of these tumors.
