Granulomatous rosacea in infants. Report of three cases and discussion of the differential diagnosis

Abstract

Granulomatous rosacea is a variant of rosacea characterized by hard cutaneous papules and nodules in relatively normal-appearing skin that is rarely diagnosed in childhood. The differential diagnosis essentially includes perioral dermatitis and sarcoidosis. Despite the differences in clinical presentation and histopathology, there is similar responses to the same therapies used in rosacea. Therapeutic failure should lead to the investigation of other rare and controversial conditions, such as acne agminata.
