Rare finding of concomitant pseudomelanosis of stomach and duodenum; case report and literature review

Melanosis of the stomach and duodenum is a rare entity and a striking finding diagnosed by upper gastrointestinal endoscopy. Here, we describe the case of an 83-year-old female, with a complicated medical history, who was referred to gastroenterologist to assess bleeding risk. From the endoscopy, it was determined that she had both melanosis gastri and duodeni. Although both are rare, gastric melanosis appears to be even more unusual than duodenal melanosis, with only a few reported cases documented in the literature thus far.
