Complications Chronic inflammation can cause long term lymphatic obstruction. Typically, patients have disorders that present local nodes, primary lymphedema and chronic venous insufficiency. Erysipelas and trauma are major risk factors. Lymphatic edema can be developed in many acral cases accompanied by a thickening of the folds of the skin, hyperkeratosis and papillomatosis. Chronic venous edema is only partially reversible and soon becomes hard, especially confirming tenderness. All structures of the skin are affected. Dilated dermal lymphatic vessels with consequent superior organization and fibrosis result in papillomatosis. As dermal lymphatic<unk>  progreses, these skin changes become more marked and known as elephantiasis. Occasionally, tissue fibrosis and thickening may become so marked in the later stages of lymphedema that pitting is absent. Recurrent cellulitis, erysipelas and dermato-LAM-adenitis are complications of chronic lymphedema.
