Disfiguring draining sinus tracts in a female acne patient.

A 17-year-old girl with a 9-month history of papulopustular acne developed disfiguring, highly inflammatory, fluctuant nodules in both nasolabial folds within 2 months. Periodically she experienced discharge of pus and blood from these lesions. A diagnosis of disfiguring draining sinus tracts associated with acne vulgaris was made. The therapeutic regimen included intralesional corticosteroid injection, systemic corticosteroids along with a macrolide antibiotic, and systemic isotretinoin to reduce the inflammatory process. Outcome was favorable, with no recurrences during the following 10 months. Draining sinus is a malevolent lesion usually seen in severe forms of acne such as acne conglobata, acne fulminans, and acne inversa. Treatment is difficult and often unsatisfactory. In many cases, excision of the lesion is necessary to provide a permanent cure.
