Oral Cutaneous Fistulas Differential Diagnoses

  • Author: James Cade, DDS; Chief Editor: William D James, MD  more...
Updated: Sep 03, 2015

Diagnostic Considerations

The differential diagnoses include any dental and periodontal infection, odontogenic cysts and tumors, salivary gland lesions and neoplasms, and other benign and malignant neoplasms. The most common neoplastic cause of oral cutaneous fistulas is squamous cell carcinoma. Unless secondarily infected, oral cutaneous fistulas rarely, if ever, develop from benign neoplasms and cysts.

Dental infections may also mimic dermatological infections.[29]
