Double Lip: An Unusual Presentation

Double lip is a term used to describe a deformity of the upper or lower lip and consists of an accessory fold of redundant mucous membrane inside the vermilion border. Double lip is an uncommon congenital anomaly and is usually diagnosed and treated by a dentist or an oral surgeon. We present an unusual case of double lip—unusual because it was diagnosed and treated by a dermatologist and because of the histopathologic findings.
