Recurrent septic arthritis and Milroy's disease.

Milroy's disease is a rare disorder characterized by multiple physical anomalies, the most prominent of which is lymphedema of one or both lower extremities. We describe, with a review of proposed pathogenetic mechanisms, a patient with Milroy's disease who, over a 13-year period, manifested at least 14 isolated episodes of septic arthritis of the left knee. Recurrent septic arthritis associated with Milroy's disease has not been reported previously.
