A Case of Metastatic Malignant Melanoma of the Gallbladder and Small Bowel

ABSTRACT

Malignant melanoma is a rare entity that accounts for approximately 1-3% of all malignant tumors, but shows an increasing incidence. Malignant melanoma has a well-documented tendency to metastasize to the gastrointestinal tract, an affinity significantly higher than that of other primary malignant lesions. Involvement of the gallbladder in cases of widespread metastasis is uncommon in the Asian area. We report a malignant melanoma which involved multiple organs, the gallbladder and the small bowel. We also present a review of literature.
