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.
