Colchicine effect has been described recently in gastrointestinal biopsies, where it can result in accumulation of metaphase mitoses and epithelial disorganization. We describe the case of a colonic hyperplastic polyp with colchicine effect from a 52-year-old woman who was receiving colchicine for primary biliary cirrhosis. Biopsy of the polyp revealed prominent metaphase mitoses and focal loss of nuclear polarity in the surface epithelium, features that mimicked a serrated adenoma. Distinguishing between hyperplastic polyp and serrated adenoma is important because of the different management implications and the increased potential for neoplastic progression in the latter.
