[Lupoid rosacea as a special form of rosacea: review of pathogenesis and therapeutic options].

Lupoid or granulomatous rosacea is classified as a special form of rosacea which along with the typical rosacea symptoms features monomorphic yellow-brown and red papules and nodules on the cheeks and periorificial areas. Histology shows noncaseating epithelioid cell granulomas with surrounding mononuclear cell infiltrates. It is difficult to treat. Currently, the only officially approved systemic treatment is tetracycline. However, there is a broad experience with off-label use of isotretinoin (10-20 mg daily). We describe a patient with an excellent response to 20 mg isotretinoin daily.
