Most cases of the popliteal cyst rupture in rheumatic diseases have been reported in patients with rheumatoid arthritis. A ruptured popliteal cyst is unusual in other diseases, especially in gouty arthritis. The clinical presentations of a ruptured popliteal cyst may include pain, swelling, tenderness and erythema of the calf, and mimic deep vein thrombophlebitis. It is therapeutically important to differentiate ruptured popliteal cyst from deep vein thrombophlebitis. A ruptured popliteal cyst in gouty arthritis has never been reported in Korea. We would like to report one case of the ruptured popliteal cyst into the calf in gouty arthritis mimicking deep vein thrombophlebitis.
