Extraoral sinus tract misdiagnosed as an endodontic lesion.
The extraoral sinus tract may occur as a result of an inflammatory process associated with a necrotic pulp. However, several non-odontogenic disorders may also produce an extraoral sinus tract. Thus, the differential diagnosis of this clinical finding is of paramount importance in providing appropriate clinical care because misdiagnosis of this condition may result in healing failure or unnecessary treatment. This case report of a 19-yr-old male patient describes an extraoral cutaneous sinus tract misdiagnosed as an endodontic lesion. Consequently, the patient underwent unnecessary exploratory procedures and antibiotic therapy. Identification of the inflammatory source of the lesion and removal of the affected tissue led to tissue healing.
