We report the case of a male patient of 75 years old who presents with abdominal pain, hyporexia, early satiety, general malaise and watery stools, admitted in emergency for an episode of syncope. On physical examination, hepatomegaly of 6cm below the right costal margin was detected. CT scan showed multiple liver metastases. An upper endoscopy found multiple hyperpigmented lesions on the second portion of the duodenum. Histology and immunohistochemistry studies concluded it was duodenal melanoma. Skin and ocular examination did not reveal associated neoplastic lesions.
