Childhood malignant blue nevus of the ear associated with two intracranial melanocytic tumors-metastases or neurocutaneous melanosis?
Blue nevus is an uncommon pigmented tumor of dermal melanocytes that has traditionally been classified into common and cellular variant. It is usually a skin tumor in adults but can become apparent in early childhood or even be present at birth. Malignant blue nevus is a rare melanocytic tumor of the skin arising from a preexisting cellular blue nevus. We report a multinodular blue nevus of the left ear in an 11-year-old girl who also had 2 intracranial melanocytic lesions. Differential diagnosis between metastases from malignant blue nevus and neurocutaneous melanosis is discussed.
