[Benign tumors of the lung and pleura (author's transl)]

218 benign tumors of the lung and pleura, 190 of which were operated, are discussed. Little doubt exists about the necessity of operative removal in cases of benign pleuro-pulmonary tumors. Therapeutic management depends on histology, localisation and the extent of growth. The majority of untreated benign tumors have a poor prognosis even if malignant degeneration does not occur. Postoperative prognosis of rehabilitation and resocialization is good.
