Abstract
In the clinical course of malignant melanoma, which can metastasize to multiple organs, gallbladder metastases are rarely detected. A 69-year-old man who underwent resection of a primary malignant melanoma was subsequently treated with nivolumab for lung metastases and achieved complete response. Seven years after surgery, multiple nodules were found in the gallbladder, and he underwent laparoscopic cholecystectomy. The postoperative diagnosis was metastases of malignant melanoma. He has been recurrence-free 8 months after surgery. If radical resection is possible, such surgery should be performed for gallbladder metastases found in patients with other controlled lesions of malignant melanoma.
