Lymphedema
Introduction
Lymphedema is edema of a limb due to lymphatic hypoplasia (primary) or to obstruction or disruption (secondary) of lymphatic vessels. Symptoms and signs are brawny, fibrous, nonpitting edema in one or more limbs. Diagnosis is by physical examination. Treatment consists of exercise, pressure gradient dressings, massage, and sometimes surgery. Cure is unusual, but treatment may lessen symptoms, slow progression, and prevent complications. Patients are at risk of cellulitis, lymphangitis, and, rarely, lymphangiosarcoma. (See also Overview of the Lymphatic System .)
