Congenital inclusion dermoid cyst located over the region of the anterior fontanel in adult Nigerians: report of two cases.

Two cases of a congenital inclusion dermoid cyst located over the region of the anterior fontanel are described in adult Nigerians, aged 28 and 32 years. In both cases, the cystic lesion was noticed at birth over the anterior fontanel as a small soft lump, and was carried on the head from infancy into adult life. The clinical, radiological, and the operative findings revealed no intracranial extension. The two lesions were histologically verified as dermoid cysts. Surgical excision was curative.
