Giant congenital naevus of the scalp and cranium: case report and review of the literature.

We report a giant congenital naevus of the scalp which involved skin, galea, full thickness cranial bone, dura and the intracranial venous sinuses. The literature on giant congenital naevi with direct involvement of underlying bone is reviewed.
