A case is presented of a 73-year-old male patient who was operated for a gastric adenocarcinoma of the antrum. A distal subtotal gastrectomy plus D2 lymphadenectomy were practiced. During the anatomic and pathologic examination of the surgical piece, a second tiny tumor was found in the wall of the antrum and that was covered with a normal mucosa separated from the adenocarcinoma. The histologic examination confirmed another synchronous incidental neoplasm, a spindle-cell gastrointestinal stromal tumor, positive for the tumor marker CD117. This paper is aimed at presenting synchronous tumor entity, to review its characteristics and the current etiologic and pathogenic theories of this synchronic condition according to the specialized literature.
