Malignant melanoma in children.

Six patients with prepubertal malignant melanoma are presented. Three were metastatic. One was congenital in a giant pigmented nevus. A second was found at 6 mo of age to have metastatic lesions. All were treated aggressively and had a favorable outcome. Aggressive treatment, once malignant melanoma is diagnosed, is recommended. Prognosis does not differ markedly from similar lesions in adults.
