ABSTRACT
Among metastatic pancreatic tumors, malignant melanomas are rare. Here, we report a very rare case of a malignant melanoma that involved only the pancreas and liver, and was difficult to differentiate from a neuroendocrine tumor of the pancreas with a liver metastasis. A 65-year-old- male with no history of a malignant melanoma exhibited hypervascular hepatic and pancreatic tumors on computed tomography and contrast-enhanced endoscopic ultrasonography. He lacked lesions of the skin, eye, and gastrointestinal tract on physical examination, upper endoscopy, and a whole-body positron emission tomography-computed tomography scan; these sites are common primary sites of malignant melanoma. Finally, endoscopic ultrasound-guided pancreatic core biopsy and percutaneous ultrasonography-guided liver biopsy confirmed malignant melanoma of the pancreas and liver.
