Pseudothrombophlebitis in an adolescent without rheumatic disease. A case report.

Pseudothrombophlebitis syndrome is the occurrence of calf pain and swelling caused by extrinsic compression of the popliteal vessels by an enlarging Baker's cyst or by calf inflammation that occurs as the result of a ruptured Baker's cyst. Few cases of pseudothrombophlebitis syndrome have been reported in patients less than 18 years of age, and nearly all these young patients had juvenile rheumatoid arthritis. Reported here is the case of a 17-year-old male patient without rheumatic disease who presented to the outpatient clinic with a 1-week history of an increasingly painful swelling of the right calf without any history of precipitating factors for a deep vein thrombosis.
