title: Cartilaginous choristoma of the lower lip.
abstract: Choristoma is a tumor-like mass consisting of normal cells in an abnormal location. Cartilaginous choristoma, which is composed of ectopic cartilaginous tissue, very rarely presents in the oral cavity and most commonly in the tongue. Here we report an extremely rare case of cartilaginous choristoma of the lower lip.
