Melanosis coli is a condition usually associated with chronic laxative use in which dark pigment is deposited in the lamina propria (one of the lining layers) of the large intestine (colon). The pigment deposition results in a characteristic dark brown to black discoloration of the lining of the large intestine.
A 50-year-old woman underwent colonoscopy for rectal bleeding. Her entire colon appeared dark brown and black, a finding consistent with the diagnosis of melanosis coli (Panel A). Random biopsy specimens from the descending colon revealed sheets and clusters of macrophages laden with brownish pigment in the lamina propria (Panel B, arrow).
