A Case of Cutaneous Sinus Tract of Odontogenic Origin / 대한피부과학회지

A cutaneous sinus tract of odontogenic origin occurs when purulent by-products of dental pulp necrosis spread along the path of least resistance from the root apex to the skin on the face. Patients presenting with this condition usually visit a dermatologist first, as the lesion can mimic various dermatologic pathologies, ranging from an epidermal cyst to basal cell carcinoma. The location of the sinus in the head and neck region should lead the dermatologist to seek a dental origin in order to avoid misdiagnosis. The lesion may persist for long periods before a correct diagnosis is made and the odontogenic source is treated appropriately. Herein, we report a case of a cutaneous sinus tract of odontogenic origin.
