Pseudomelanosis duodeni is characterized by endoscopic findings of black or black-brown speckled pigmentation in the duodenal mucosa, usually diagnosed via biopsy. This report presents a case of a 75-year-old male presented with left lower abdominal pain, change in bowel habits, and decreased appetite. Gastroduodenoscopy and biopsies of the duodenum and antrum lead to the diagnosis of pseudomelanosis duodeni.
