Odontogenic cutaneous fistula (OCF) is the result of an abnormal canalization originating from chronic periapical infection. It represents a diagnostic challenge, as it is frequently misdiagnosed as dermatological lesion. There is a broad differential diagnosis, including pyogenic granuloma, cutaneous tuberculosis or congenital malformations, among others. We report the case of a 46-year-old man diagnosed with OCF who presented a rapid improvement after extraction of the affected dental pieces and fistulectomy. We consider knowledge of this pathology to be important in order to avoid unnecessary delays in diagnosis and proper treatment.
