    Author: Alrashid MHR, Thomas N, Idnani DD, ALkhaleefa FA.
    Journal: Arab J Gastroenterol; 2024 Aug; 25(3):320-322. PubMed ID: 38705814.
    Abstract:
    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.
