The labial pits describe a rare anomaly, which shows blind-ended epidermal invaginations of the lip mucosa. Their diameter is usually less than 4mm with their depth being 1 to 4mm. Mostly, they include fistulae which are normally asymptomatic, but if they are linked to a salivary gland they can cause secretion and concern the patient. In that case, a sufficiently deep excision with the removal of the involved glands is required. The condition is suggested to represent a genetic disorder exhibiting autosomal dominant inheritance.
