Reiter syndrome is a systemic disorder, originally defined as a triad of arthritis, urethritis and conjunctivitis.This symptoms complex usually follows an episode of either urethritis or dysentery.Skin and mucosal involvement is observed in about 10% of the cases.We present a case of Reiter's syndrome in a 55-year-old man who developed the typical skin lesions -kerathoderma blenorrhagicum.The disease started with a severe asymmetric oligoarthritis a month after the patient had urethritis.Two weeks after the onset of the arthritis red patches on the palms and plants appeared, which transformed quickly in harder and elevated plaques.
