Adenocarcinoma e tumor estromal (GIST) sincrônicos no estômago: uma rara ocorrência

Abstract

A concomitant epithelial and stromal tumor in stomach is unusual in the literature. The purpose of this paper is to report the case and it's therapeutic management. A 72 year old black male patient , which upper digestive endoscopy showed a gastric neoplasm (Borrmann III) at incisura angularis and the biopsy revealed adenocarcinoma. A subtotal gastrectomy with D2 limphadenectomy and Roux-en-Y reconstruction was performed. The histopathology studies confirmed an adenocarcinoma and a gastric stromal tumor, whose immunohistochemical exam was compatible to GIST. Seventeen months after surgery, a computadorized tomography revealed a retrogastric tumor and laparotomy was indicated to remove the lesion.
