Abstract

ATHANAZIO, D. A. et al. Differential diagnosis between glomus tumor and carcinoid of the stomach. J Port Gastrenterol. [online]. 2009, vol.16, n.1, pp.29-32. ISSN 0872-8178.

We report a rare case of gastric glomus tumor with preoperative diagnosis of carcinoid tumor in a 57-year-old man. Immunophenotyping panel revealed expression of smooth muscle actin and vimentin by tumor cells with pericellular collagen IV and absence of expression of neuroendocrine makers. Recent advances on diagnosis of gastric glomus tumor and understanding of its biological behaviour is reviewed. This case highlights the overlapping features of gastric glomus tumor and carcinoid suggesting that immunohistochemistry should be considered for this differential diagnosis in all cases.

Keywords : Glomus tumor; Carcinoid tumor; Stomach.
