Morsicatio Labiorum / 대한피부과학회지

ABSTRACT

Morsicatio is a condition caused by chronic irritation of the tongue (morsicatio linguarum), buccal (morsicatio buccarum) or labial mucosa (morsicatio labiorum). The condition shows a macerated, grey-white lesion of mucosa where bacterial colonies form and is caused by continuous biting, chewing and sucking of the cheeks or lips. We herein report a case of morsicatio labiorum which occurred in a woman. This is a rarely encountered mucocutaneous disorder, and has never before been reported in the Korean dermatological literature.
