Odontogenic Cutaneous Fistula: A Diagnosis to be Remembered by the Dermatologist

Keywords: Cutaneous Fistula/diagnosis, Dental Fistula


Odontogenic cutaneous fistulas occur mostly on the mandibula but we report a case due to a periapical infection of a maxillar teeth with a less frequent location: a 32 years-old female patient with an erythematous nodular lesion in the nasogenian sulcus for about 1 year that recurred after surgery. Examination of the oral cavity showed darkening of the upper arch canine tooth, ipsilateral to the skin lesion and imaging examination confirmed a periapical infection responsible for the extra-oral cutaneous fistula.
