[The lymphatic system and the skin. Classification, clinical aspects und histology].

Dermatology offers many clinical examples of abnormalities in the production, absorption and transport of lymph. Lymphatic thromboses also occur. Many diseases are not named in accordance with their underlying pathogenesis. Malignant lymphedema must be recognized immediately. The differential diagnosis of regional lymphedema is also part of dermatology. Stemmer sign is a clue to chronic lymphedema. Lymphoedema is first divided into primary and secondary forms, depending on the cause, and then subdivided into stages depending on severity. Complications of chronic lymphedema include recurrent erysipelas, superficial lymphangiectases, verrucous lymphedema (papillomatosis lymphostatica) and angiosarcoma, which is often multifocal. Established diagnostic approaches are available to correctly diagnose lymphatic disease. The treatment of chronic lymphedema centers around reducing the edema which then influences all of the other problems. The physical therapeutic approach to reducing blockage is the best way to achieve these goals.
