Congenital inclusion dermoid cyst of the anterior fontanel

Abstract

An unusual type of dermoid cyst is reported in 10 African infants. In these cases a soft, cystic mass located over the anterior fontanel was noted shortly after birth and gradually enlarged. The cyst had no intracranial extension and was easily excised intact. The clinical and x-ray findings of the cyst are described and compared with the usual dermoids. The histology and the contents of the cyst are detailed and some peculiarities of this lesion pointed out.
