Cutaneous sinus tract of dental origin

47-year-old woman presented with a nodular lesion on her face that had been discharging pus intermittently for 7 months. She could not recall any prev ious trauma to the site. Dermatologic examination revealed a nontender, ery thematous, nodular, draining lesion on the patient's chin (Fig. 1). Dental examination showed poor oral hygiene and severe chronic periodontitis, but no acute infection. Radiography demonstrated diffuse periapical radiolucenc y associated with the right central mandibular incisor (Fig. 2). The patien t was diagnosed with chronic apical periodontitis. Because it was too late for her oral condition to be corrected with endodontic treatment, the tooth was extracted and the scar on her chin was revised later.
