SHIMIZU, Akiko et al. PRIMARY GASTRIC ADENOCARCINOMA CONCOMITANT WITH GASTROINTESTINAL STROMAL TUMOR (GIST): : EPORT OF TWO CASES. Gen [online]. 2015, vol.69, n.3, pp.74-77. ISSN 2477-975X.

Worldwide,  gastric cancer (GC) is the second most frequent cause of death by cancer. Other histological types as lympho- mas and sarcomas are less frequent, resulting even rarer, the synchronous development of adenocarcinoma with a tumor of the gastrointestinal stromal (GIST). In this work are documented two cases of patients with gastric Adenocarcinoma concomitant with Gastrointestinal stromal Tumor, with different clinical presentation. The first of these is 76-year-old female patient who goes by dyspeptic symptoms with early gastric Ca IIc + III, the patient undergoes radical subtotal gastrectomy and the surgical specimen additionally shows subepithelial elevated lesion on gastric body with lesser curvature measuring 0.6 cm, histopathological evaluation showed that the gastric cáncerinvasión was confined to thethe submucosal layer, case of synchronous  tumours with different histogenesis.  The other case is 66-year-old female patient who came to our gastric cáncer screening and we found a colission tumor in the stomach.
