[Synchronous adenocarcinoma and lymphoepithelioma-like carcinoma in the stomach: a case presentation and literature review]. / Adenocarcinoma y carcinoma tipo linfoepitelioma sincrónico en estómago: presentación de un caso y revisión de la literatura.

ABSTRACT

Gastric cancer is one of the main causes of death in the world. In Venezuela, gastric tumors represent 37% of all malignant tumors of the digestive system, but only 1,6% to 3,1% of these cases are lymphoepithelioma-like carcinoma. Synchronous neoplastic lesions are also rare. The clinical case presented herein, a man with two synchronous tumor lesions, is the first of its kind in this country. Despite their incipient aspect, the histologic study reported two malignant tumors of epithelial origin well-differentiated adenocarcinoma and lymphoepithelioma-like carcinoma.
