Congenital malignant melanoma.
The diagnosis and management of a 3-day-old infant with an exophytic pigmented growth on her back and chest are discussed. At 3 days of age, the child underwent a complete surgical excision of this lesion with immediate coverage by partial-thickness skin grafts. Pathologically, the lesion proved to be a thoracolumbar congenital melanocytic nevus with multiple focal areas of malignant melanoma. The child is now 3 years past surgery and shows no evidence of recurrence or distant metastases. The importance of this case lies in the presence of overt malignant melanoma at birth within a giant congenital nevocytic nevus.
