Pseudomelanosis duodeni. Case report and review of literature.
Pseudomelanosis duodeni is an extremely rare disease that has been only recently recognized. We present what we take to be the first Oriental case with typical endoscopic and histological manifestations. With detailed studies of histochemistry and electron microscopy, we have confirmed that the pigment is composed of iron and lipofuscin. A detailed review of the literature may be found here.
