Acne vulgaris.
Acne vulgaris is a disease of the pilosebaceous unit that affects nearly all persons to some degree during the teenage years. It is a disease that should be treated because of the anxiety and disfigurement it causes in the affected patient. Acne therapy is directed against the three probable pathogenic processes in acne: (1) abnormal keratinization of the sebaceous follicle, (2) excessive production of sebum, and (3) proliferation of bacteria in the follicle. Superficial acne consisting of comedones and small papulopustules will frequently respond to topical therapy such as retinoic acid, benzoyl peroxide, and topical antibiotics. Deeper lesions require systemic antibiotics of which tetracycline is the drug of choice. Severe, recalcitrant cystic acne usually responds well to the oral retinoid, isotretinoin. The severe teratogenic effects of isotretinoin on a developing fetus make this a risky drug to prescribe for women with childbearing potential. In such cases the greatest precautions should be taken to avoid pregnancy during a course of isotretinoin. Such precautions include pregnancy testing, contraceptive counseling, and the use of at least two effective forms of birth control in sexually active women.
