[Triple primary malignancies (malignant melanoma, laryngeal cancer and hepatoma)]

A 61 year-old male patient, diagnosed to have a malignant melanoma in the left arm in April, 1981, was treated by chemotherapy (gamma-INF and DAVP) and a left axillary lymphadenectomy. In March, 1985, he had complained of hoarseness and an early laryngeal squamous cell carcinoma was found, and was subjected to laser treatment. On May 25, 1986, during his hospitalization for treatment of a multiple metastasis of a malignant melanoma, he suddenly suffered from a gastroduodenal perforation. During an emergency operation, a third cancer, a primary mixed hepatocellular and cholangiocellular carcinoma, was discovered.
