Description:
Perineuriomas of the gastrointestinal tract, formerly known as benign fibroblastic polyps, most commonly occur as polyps on screening colonoscopy, particularly in the distal colon. Gastric examples are exceedingly rare. We report the sixth patient with a gastric perineurioma in a 57-year-old female. Histologically, the lesion was composed of bland spindle cells without cytologic atypia or mitotic activity located in the gastric lamina propria. The spindled cells were strongly positive for GLUT1 and focally reactive for epithelial membrane antigen (EMA). The morphologic and immunophenotypic findings were those of gastric perineurioma.
