Abstract

A 64-year-old woman with life-long constipation and extensive use of laxatives containing anthraquinone received colonoscopy examination during a health checkup. Lower gastrointestinal endoscopy showed diffuse dark pigmentation in the colonic mucosa that contrasted dramatically with the normal pink ileal mucosa of the ileocecal valve (Figure 1A, 1B).
