Lymphedema.

Abstract

Lymphedema is swelling that results from the accumulation of lymph due to a malformation or obstruction of the lymphatic system. Once other causes (cardiac, renal, and hepatic) of lower extremity edema have been ruled out, categorization into primary and secondary lymphedema is undertaken. A complete history, physical, and laboratory evaluation is completed to diagnose the specific type of lymphedema and appropriate management is recommended.
