IMAGING OF PULMONARY-CUTANEOUS DISORDERS - MATCHING THE RADIOLOGIC AND DERMATOLOGICAL FINDINGS

Dermatologic lesions are often associated with pulmonary disorders and vice versa, Diseases with pulmonary and cutaneous manifestations can be divided into four major categories: (a) congenital and developmenta l disorders with cutaneous-pulmonary manifestations (Ehlers-Danlos syn drome, generalized elastolysis, yellow nail syndrome, neurofibromatosi s, hereditary hemorrhagic telangiectasia); (b) primary dermal diseases with associated pulmonary manifestations (septic vasculitis, malignan t melanoma, Kaposi sarcoma); (c) primary pulmonary diseases with assoc iated cutaneous manifestations (tuberculosis, Pseudomonas pneumonia, m ycoplasmal pneumonia, adenocarcinoma, metastasis); and (d) cutaneous-p ulmonary conditions (multisystem disorders) (progressive systemic scle rosis, systemic lupus erythematosus, Wegener granulomatosis, sarcoidos is). A series of selected cases is used to illustrate the radiologic a nd dermatologic features of conditions that affect both the lung and d ermal tissue, Specific emphasis is placed on the dermatologic manifest ations of disease. Diagnosis of a pulmonary-cutaneous disorder require s familiarity with the morphologic appearance of the cutaneous lesion.
