Primary Malignant Melanoma of Gallbladder; an overview of its presentation, diagnosis and management

Abstract

Malignant melanoma of gallbladder is a rare entity; mostly it is metastatic in nature. Primary malignant melanoma is extremely rare. In this article we have presented a case of primary malignant melanoma of gallbladder that was treated successfully by surgery. Presentation of primary gallbladder melanoma is no different from other gallbladder malignancies; diagnosis is purely based on histology or cytology. Surgery is the mainstay of treatment, though multiple systemic therapies are under trial. Overall prognosis is poor with some exceptions.
