Three unrelated patients with psoriasis present since birth did not have a family history of psoriasis. The oldest of the three developed crippling psoriatic arthritis before the age of 13. The child who is now eight years old has continued to have severe psoriasis. The infant who is at present under 1 year of age has psoriatic lesions that are being controlled with topical application of steroid cream.
