[Castleman tumor].

Abstract

A case of a mediastinal benign tumor in a 56 year old male is presented. The tumor was detected during a routine chest radiographic examination. The patient was asymptomatic. During thoracotomy two tumors were found. One was localized in the middle mediastinum the other in the posterior mediastinum. Both tumors were removed completely. Basing on the results of the clinical examination, of the laboratory data and the histopathological examination of the resected tumors a diagnosis of Castleman's tumor of the plasma-cell type was made.
