Article: Malignant melanoma of the gallbladder: A case report and literature review

Metastatic melanoma of the gallbladder is extremely rare. It has a poor prognosis. Its optimal treatment remains unclear. Surgical resection is generally considered the mainstay of treatment. However, there are no standards to guide the choice between open surgery and laparoscopic surgery. Criteria for the extent of surgical dissection have not been established yet either. We report a patient diagnosed with gallbladder cancer who underwent extended cholecystectomy but had metastatic melanoma at the final biopsy. We reviewed the literature on the treatment of metastatic melanoma in the gallbladder and compared it with our case to determine a treatment strategy.
