A rare case report: Non-syndromic double, double lip

Double lip is a rare developmental oral anomaly, affecting the lips. It is also referred to as "macrocheilia," in which a fold of excess or redundant labial tissue is apparent at rest or on smiling. It usually involves the upper lip, less frequently the lower lip either unilaterally or bilaterally, but rarely both the lips are affected as in the presented case. It may interfere with speech and esthetics; surgery may be indicated for cosmetic reasons only. In this article, the authors report a rare case of non-syndromic congenital double upper and lower lip in a 70-year-old male patient, with a brief review of literature.
