Rosacea: A cutaneous disorder primarily of convexities of the central part of the FACE, such as FOREHEAD; CHEEK; NOSE; and CHIN. It is characterized by FLUSHING; ERYTHEMA; EDEMA; RHINOPHYMA; papules; and ocular symptoms. It may occur at any age but typically after age 30. There are various subtypes of rosacea: erythematotelangiectatic, papulopustular, phymatous, and ocular (National Rosacea Society's Expert Committee on the Classification and Staging of Rosacea, J Am Acad Dermatol 2002; 46:584-7).Facial DermatosesErythema: Redness of the skin produced by congestion of the capillaries. This condition may result from a variety of causes.Mite Infestations: Infestations with arthropods of the subclass ACARI, superorder Acariformes.Dermatologic Agents: Drugs used to treat or prevent skin disorders or for the routine care of skin.Dermatitis, Perioral: A papular eruption of unknown etiology that progresses to residual papular erythema and scaling usually confined to the area of the mouth, and almost exclusively occurring in young women. It may also be localized or extend to involve the eyelids and adjacent glabella area of the forehead (periocular dermatitis). (Dorland, 28th ed)Rhinophyma: A manifestation of severe ROSACEA resulting in significant enlargement of the NOSE and occurring primarily in men. It is caused by hypertrophy of the SEBACEOUS GLANDS and surrounding CONNECTIVE TISSUE. The nose is reddened and marked with TELANGIECTASIS.Sulfacetamide: An anti-infective agent that is used topically to treat skin infections and orally for urinary tract infections.Skin Diseases, Papulosquamous: A group of dermatoses with distinct morphologic features. The primary lesion is most commonly a papule, usually erythematous, with a variable degree of scaling on the surface. Plaques form through the coalescing of primary lesions.Telangiectasis: Permanent dilation of preexisting blood vessels (CAPILLARIES; ARTERIOLES; VENULES) creating small focal red lesions, most commonly in the skin or mucous membranes. It is characterized by the prominence of skin blood vessels, such as vascular spiders.
