Ectropion of lip (Q88576)

An eversion of the lip resulting from contractures involving adjacent perioral skin. The lower lip is much more commonly affected than the upper lip. Ectropion of the lower lip is a particular complication of severe facial burns. Ectropion may also result as a complication of surgery or cryotherapy involving perioral skin, e.g. for removal or destruction of skin cancers. Rarely it may result from genetic skin conditions, especially harlequin ichthyosis.
