The differential diagnosis largely depends on the pattern of rosacea. Erythematotelangiectatic rosacea (ETR) can resemble seborrheic dermatitis, lupus erythematosus, and other photodermatoses. Carcinoid syndrome and mitral valve incompetence are overlooked causes of erythema and telangiectasia. Acneiform rosacea may be simulated by acne, bromoderma and iododerma, perioral dermatitis, and pustular folliculitis. Acne agminata can be indistinguishable from lupus vulgaris and cutaneous sarcoidosis.
