摘要

Van der Woude syndrome (VWS; OMIM 119300) is an autosomal dominant developmental malformation presenting with bilateral lower lip pits related to cleft lip, cleft palate, and other malformations in about half the patients. These congenital lip pits appear clinically as a defect in the vermilion border of the lip. They are commonly related to fistulae of minor salivary glands with or without excretion. Usually the cause of cosmetic defects, VWS is preferably treated through simple excision. This report aims to describe a case of VWS involving a patient who presented with isolated congenital bilateral lower lip pits related to fistulae of the minor salivary glands, which were treated successfully through simple excision.
