[Reiter's disease in children].

Two cases of diagnostic mistakes of Reuter's disease in for children have been described. 7-year-old girl has been operated on for the suspicion on hematogenic osteomyelitis. The diagnosis was not confirmed. The symptoms of Reuter disease-right knee and hip joints synovitis-have appeared in postoperative period. A nonsignificant trauma in 9-year-old boy was the reason for the diagnosis of nontraumatic arthritis. Despite of Reuter's disease symptoms (arthritis, urethritis and conjunctivitis) the immobilization of extremities has been done. In 7 of 30 patients the Reuter's disease has not been diagnosed from the beginning.
