Abstract
Chronic granulomatous disease (CGD) is a rare, inherited disorder, in which phagocytic cells, through an enzyme defect, are unable to produce microbicidal oxidants; affected individuals are thereby unduly susceptible to certain life-threatening bacterial and fungal infections and require lifelong antibiotic and antifungal prophylaxis. We present the case of an adolescent CGD patient whose recalcitrant acne vulgaris and subsequent recurrent facial abscesses were successfully treated with isotretinoin; swift resolution of this and similar patients' acne lesions is paramount, as these lesions may serve as a portal of entry for systemic infections and may pose a significant risk for scarring. Isotretinoin is associated with an increased rate of cutaneous Staphylococcus aureus carriage as well as exuberant granulation responses, both of theoretical concern in CGD patients. The therapeutic outcome of isotretinoin in treatment-resistant cases of acne in CGD patients has not been reported in the literature; we present this case to advocate an underreported use of isotretinoin in the prevention of acne, its subsequent cyst formation, and scarring patients with CGD.
