title: Gram-negative acne.
abstract: Gram-negative acne is an unusual, distinctive disease that is probably increasing in frequency. It seems directly related to long-term therapy with multiple antibiotics and in one of our cases with the misue of topical corticosteroids. Cultures should be taken from the obvious as well as the not so obvious sites--nares, ear canals, and perineum--with special technique to maximize growth of gram-negative and anaerobic bacteria. Our patients had a good response to appropriate systemic antibiotic and topical therapy.
