Primary essential cutis verticis gyrata--a case report.

Cutis verticis gyrata (CVG) is a skin deformity characterised by excessive growth of the skin of the scalp, resulting in furrows and folds which are similar to gyri of the brain cortex. CVG can be classified into two forms: 'primary' (essential and non-essential) and 'secondary'. The primary non-essential type is associated with the neurological and ophthalmological changes, while the primary essential form does not present any other disorder except for the cutaneous alterations. Secondary forms of CVG are much more frequent and accompany other pathologies. The treatment consists of local hygiene and surgical resection of skin excess. This study reports a case of CVG of the primary essential type in a male patient, who was referred to us for a surgical treatment.
