A seven-year-old girl, with erythematous-squamous rash, was admitted to our clinic to decide upon the diagnosis and treatment, being transferred from a county hospital. Heredo-collateral antecedents - an aunt, related to her mother, with psoriasis. When admitted, the patient presented prominent non-pruriginous erythematous plaques, clearly marked and covered by thick, silvery-white scales, easily exfoliating, all over at the level of: scalp, earlobes, neck, torso, limbs, periungual, axillary and genital areas. The dermatological examination: psoriasis vulgaris in patches and plaques, a diagnosis also confirmed histopathologically. Using a local dermatologic treatment, the evolution was favorable, the patient initially presenting thick squamae, then, gradually, there occurred the psoriasis whitening. We presented this case since psoriasis is rarely met at this early age.
