Cutaneous intestinal metaplasia: An unusual cause of peristomal complication with malignant potential

Peristomal ulcer with cutaneous intestinal metaplasia, defined by scattered colonic crypts within variably intact epidermis, is an exceedingly rare pathologic diagnosis, which possesses the potential to progress to primary adenocarcinoma. Herein, we report the third case of cutaneous intestinal metaplasia in a peristomal ulcer and emphasize the importance of diagnosis and surveillance when managing this rare entity.
