[Intrapulmonary sarcoid, presenting as tumor or as multiple pulmonary nodules with and without cavities (author's...

Eight cases of nodular, partially cavitary intrapulmonary--mainly acute--sarcoid mimicking metastatic disease or cavitary disease of other etiology are presented to point out the fact that sarcoid can occur in this form. Almost all these patients were young and asymptomatic with the lesions discovered incidentally on the chest films taken for other reasons. The pulmonary nodules and cavities present differential diagnostic problems; with the concomitant--or previous--presence of hilar or mediastinal lymph-adenopathy and the finding of unsharp borders of the nodules somewhat supporting the diagnosis of sarcoid.
