Cutis verticis gyrata is characterised by hypertrophy
and folding of skin of scalp leading to gyrated
appearance. Polan and Butterworth1 classified it
into primary and secondary forms. Secondary CVG
has been described with a wide variety of causes.
Congenital melanocytic neavus appears to be the
most common2. However it has been described with
other naevoid abnormalities like Neavus
lipomatoses, connective tissue nevi, genetic
disorders such as neurofibromatoses, and endocrine
disorders like acromegaly.
