Abstract

Rosacea is one of the most common conditions on the face. Rosacea affecting the central parts of the face and is characterized by erythema, flushing, telangiectasia; papules and pustules. Cutaneous flushing – a common presenting complaint to dermatologists, allergists, internists, and family practitioners. Diagnosis typical cases of rosacea is not difficult, but many diseases, both benign and malignant, can be associated with facial flushing and erythema. Most cases are caused by very common, benign diseases, such as rosacea, that are readily apparent after a thorough taking of history and physical examination. However, in some cases, accurate diagnosis requires further laboratory, radiologic, or histopathologic studies. In particular, the serious diagnoses of carcinoid syndrome, pheochromocytoma, mastocytosis, systemic lupus erythematosus, dermatomyositisand anaphylaxis need to be excluded by laboratory studies. In the article, we present main diseases that dermatologysts should consider when diagnosing rosacea.
