The gastrointestinal tract is a common site for metastases in malignant melanoma. However, there is no prior report of surgically resected metastatic malignant melanoma of the duodenum. We report a patient, who was treated by pancreatoduodenectomy for metastatic melanoma. The patient was a 69-year-old woman, who had histories of nasal malignant melanoma and cecal cancer. She was hospitalized because of dizziness and tarry stoll. Endoscopic examination revealed a blackish elevated lesion in the second portion of the duodenum, and biopsy confirmed the diagnosis of metastatic malignant melanoma. As no other metastases were found by systemic examinations, pancreatoduodenectomy was performed. Adjuvant chemotherapy was carried out 2 months after the operation and she was discharged 3 months after surgery. In April 1995, 6 months after surgery, there were no signs of recurrence.
