  • Hepatobiliary Medicine

Background:

  • Primary melanoma is a malignant neoplasm originating from melanocytes.
  • The most common primary sites for melanoma are the skin and squamous mucous membranes.
  • Primary melanoma of the biliary tract is exceptionally rare.

Observation:

  • This study reports two new cases of primary melanoma of the bile ducts.
  • These cases represent the fourth and fifth documented instances globally.
  • The rarity underscores the diagnostic challenge and limited understanding of this condition.

Findings:

  • Two patients were diagnosed with primary bile duct melanoma.
  • This significantly increases the number of reported cases in medical literature.
  • Further research is needed to understand the etiology and behavior of biliary melanomas.
