Abstract

We report the rare case of a 68-year-old man who had two separate and histologically dissimilar gastric tumors: a poorly differentiated adenocarcinoma and a carcinoid. The latter tumor showed argyrophilic granules (Grimelius technique) and positivity for chromogranin A and neuron-specific enolase stains, confirming the neuroendocrine nature of the neoplasia. The literature concerning this subject is reviewed.

Key words
