Spontaneous regression of malignant melanoma

The case of a 47-year-old white female patient has been described with malignant melanoma that started as a node on her right ankle twelve years ago and regressed spontaneously. During the last two years of her life, dissemination of the melanoma appeared in the form of subcutaneous nodes, which regressed spontaneously in successive crops. In the course of her disease there was evidence of distant metastases to the brain. Spontaneous regression seems to have been enhanced by immunotherapy, when most of the metastases had regressed, including those in the brain.
