Melanosis Coli Associated with Aloe Consumption in a Child
Abstract
Melanosis coli is described as a black or brown discoloration of the mucosa of the colon. Such a discoloration is largely due to pigment granule deposition in macrophages in the colonic mucosa, which arises from anthraquinone-containing laxative abuse. Melanosis coli has usually been reported in the elderly. We present the first case of melanosis coli associated with aloe consumption in a Korean child.
Fig. 1
Colonoscopic finding shows brown pigmentation with aggregates of lymphoid follicles in the rectum and sigmoid (A, B). Patchy intense pigmentation, as well as focal areas of absent pigment in a reticulated pattern, were also noted (C).
Fig. 2
Light microscopic finding shows the brown pigment granule-laden macrophages (arrows) in the submucosa (A) (H&E stain, ×40) and in the lamina propria (B) (H&E stain, ×200).
