title: Pathogenesis of lipodermatosclerosis of venous disease: the lesson learned from eosinophilic fasciitis.
abstract: The histological features of lipodermatosclerosis and eosinophilic fasciitis and its variants were compared in a prospective study of outpatients attending the vascular clinic and inpatients in the Department of Medicine of a regional university hospital. Main outcome measures examined were swelling and induration of the subcutaneous layers with a stocking distribution in the calves. The inflammatory and fibrosing alterations involving the panniculus adiposus, superficial fascia and perimysium were essentially indistinguishable histologically in patients with lipodermatosclerosis or eosinophilic fasciitis and its variants. The intensity of the subcutaneous induration was related to the underlying nosological entity and the duration of the process. Infectious cellulitis was found to aggravate the clinical symptoms of lipodermatosclerosis. Since the stereotypical inflammatory and fibrosing processes in lipodermatosclerosis and eosinophilic fasciitis and its variants are similar irrespective of the initiating factors, it is suggested that there is a common final pathway in the pathogenesis of both disorders.
