Rosacea
Introduction
Rosacea is a chronic inflammatory disorder characterized by facial flushing, telangiectasias, erythema, papules, pustules, and, in severe cases, rhinophyma. Diagnosis is based on the characteristic appearance and history. Treatment depends on severity and includes topicalmetronidazole, topical and oral antibiotics, topicalivermectin, rarelyisotretinoin, and, for severe rhinophyma, surgery. Rosacea most commonly affects patients aged 30 to 50 with fair complexions, most notably those of Irish and Northern European descent, but it affects and is probably under-recognized in darker-skinned patients.
