Abstract
We report a case of brown-black pigmentation of the duodenum found in an elderly female during endoscopy for unrelated reasons. Melanin-like pigmentation of the duodenum is a rare endoscopic entity of uncertain etiology and significance. Various theories related to the etiology and pathogenesis, as well as histochemical and electron microscopic characteristics, are discussed.
