[Pseudothrombophlebitis syndrome in Reiter's syndrome].

Although the pseudothrombophlebitis syndrome has been studied for a long time it still presents some difficulties to be diagnosed and we can not distinguish it from real thrombophlebitis only by clinical methods. The author presents a Reiter's syndrome patient with recurrent Baker's cyst rupture that develops into pseudothrombophlebitis and discusses some aspects related to this diagnosis and treatment. He calls the attention to this diagnosis mainly in those patients presenting clinical signs of thromboplebitis of the inferior member and knee arthropathy.
