Granulomatous rosacea (Q90720)

Granulomatous rosacea is an uncommon and distinctive condition which is accepted as a variant of rosacea. It is characterised by chronic flesh-coloured, reddish-yellow or yellow-brown papules particularly affecting the skin around the eyes, nose and mouth. Lesions may appear singly or in profusion. The intervening skin is usually normal. Diascopy reveals the granulomatous nature of the papules and histology may show either caseating or non-caseating epithelioid-cell granulomas. It has been suggested that it is a granulomatous reaction to ruptured hair follicles. Individual papules may last for several years but may then regress spontaneously or heal with disfiguring scars.
