Primary malignant melanoma of the common bile duct is rare. Only seven cases have been described in the literature. Diagnosis is based on failure to find another primary site, histological examination with electron microscopy, and immunohistochemical tests. We describe a new case of primary malignant melanoma of the biliary tract and present a review of previous reports.
