Pancreatic metastasis from a nonpancreatic primary tumor is rare(s a potentially poor prognosis(3).Melanoma is an aggressive skin malignancy that commonly exhibits distant metastasis and poor overall prognosis(4).Isolated pancreatic metastasis from melanoma is even less common and poses significant diagnostic and therapeutic challenges.A retrospective study demonstrated that surgical resection increased the survival of patients with abdominal visceral melanoma metastases(5).However,pancreatic resection of metastatic melanoma is potentially associated with high mortality as experience with this type of surgery is limited(6).Here,we describe a rare case of isolated pancreatic metastatic melanoma treated with pancreatic resection at our hospital,including clinical features,treatment,and follow-up.A review of the related literature is also provided.
