Malignant melanoma is rare in Asians and one of the poorer prognostic diseases. Malignant melanoma accounts for only a small ratio of all skin cancers, but it causes the greatest number of skin cancer - related deaths worldwide. Melanoma incidence has continued to increase worldwide and in Korea, like other countries, the number of patients has increased compared with previous cancer incidence data. In this case report, we describe a case of a malignant melanoma patient who showed neck node metastasis (right supraclavicular area) after wide excision of facial melanoma 2 years before the diagnosis of relapse. The patient refused to get conventional western medical treatment including chemotherapy and the size of cancer increased over the 5 months of clinical follow-up. After 4 months of traditional Korean medical treatment using allergen-removed Rhus verniciflua Stokes(A-RVS), however, the size of cancer mass decreased and the patient showed no side effects. Further study will be needed in order to determine the long-term effect of allergen-removed Rhus verniciflua Stokes on patients with malignant melanoma.
