Abstract
AIM: To investigate the clinical characteristics of pancreatic malignant melanoma.
METHODS: Here we report a case of pancreatic malignant melanoma and present a meta-analysis of pancreatic melanoma based on data from well-documented case reports.
RESULTS: A 32-year-old male presented with abdominal pain and jaundice. Computed tomography showed a non-discrete mass in the head of the pancreas. A pancreatoduodenectomy was performed. Histology revealed pancreatic malignant melanoma. Immunostaining showed that the neoplastic cells were positive for Melan A and S100, and that they expressed HMB-45. A review of 13 publications reporting 15 cases identified main clinical symptoms as abdominal pain (nine cases) and jaundice (three cases). Nine patients had a history of extra-abdominal malignant melanoma. The overall median survival time was 10 mo.
CONCLUSION: Pancreatic malignant melanoma is not typified by any special clinical presentation. The diagnosis depends on biopsy or specimen histology. Surgical resection remains the best treatment choice.
