The authors report a unique case of a 79-year-old patient who presented to our attention for a skin lesion in the right cheek with no history of trauma or recent dental procedures, that underneath presented an indolent tooth-like structure inside the soft tissue of the right cheek, which at the histological study resulted to be an odontogenic choristoma. This rare histopathological diagnosis should be considered when a hard lesion is present in the head and neck region. ER -
