ATYPICAL FACIAL SCARRING AFTER ISOTRETINOIN THERAPY IN A PATIENT WITHPREVIOUS DERMABRASION

The increased use of isotretinoin therapy for severe cystic acne has p osed new problems for dermatologic surgeons. There have been recent re ports in the literature of unexpected ''atypical'' scarring after derm abrasion in patients who have previously taken isotretinoin. This scar ring was considered atypical because it occurred outside the typical ' 'danger zones'' (e.g., mandible and malar eminences) where scarring mo st often occurs after dermabrasion. This is the first reported case of atypical scarring in a patient who began isotretinoin therapy 2 month s after dermabrasion.
