Cutaneous sinus tract due to an asymptomatic dental infection
Pyogenic cutaneous lesions of the cervicofacial region may have a variety of causes but one possibility that should be considered is a cutaneous sinus tract (CST) of dental origin. Correct diagnosis is based on a high index of suspicion and radiologic evidence of a dental pathology. Patients with odontogenic CST should be referred to a dentist and the treatment consists of either endodontic therapy or extraction of the involved tooth. We present a case report with misdiagnosis of CST of dental origin.
