Abstract

ABSTRACT: In recent years, minocycline has become a commonly used agent for die treatment of acne vulgaris and rosacea. With this increased use have come reports of severe and in some cases life-threatening toxicity, often occurring in otherwise healthy young women after prolonged courses of minocycline. These adverse reactions include hepatotoxicity, druginduced lupus erythematosus, eosinophilic pneumonitis, and hypersensitivity syndrome. We describe a 35-year-old woman who had necrotizing vasculitis of the skin and uterine cervix after 2 years of minocycline therapy for acne vulgaris. Skin and cervical biopsies revealed acute inflammation involving through-and-through necrosis of vessel walls with thrombosis, focal fibrinoid change, and a perivascular lymphohistiocytic infiltrate. The disease fully resolved within 3 months of discontinuance of the minocycline therapy. Patients should be informed of these rare but potentially serious adverse effects before the initiation of minocycline therapy. Early recognition of these complications can result in complete resolution.
