Misdiagnosis of an Odontogenic Infection as a Skin Lesion: The Diagnostic Dilemma.

Extraoral sinus tracts of endodontic origin might be confused for a variety of dermatological conditions. Differential diagnosis of this clinical condition plays an essential role in providing appropriate clinical care because misdiagnosis is the most prevalent cause of prolonged therapy and healing failure. As a result, every cutaneous sinus structure affecting the face or neck should be investigated for dental issues. Its diagnosis can sometimes be difficult until the treating clinician examines the potential of a dental cause. Once an appropriate diagnosis has been established, definitive treatment, consisting of root canal therapy or tooth extraction, to remove the primary source of infection is a straightforward and successful operation.
