[Value of thoracoscopy in the diagnosis of solid tumors extending into the pleural cavity].

Abstract

Thoracoscopy examinations in 5 cases of solid tumors of the pleura: 1 case of Pancoast's and Tobias' tumors of neoplastic origin, 1 case of asbestosis-induced fibrohyaline plaques, and 2 cases of benign pleural tumors, 1 neurinoma emphasized the diagnostic value of thoracoscopy for tumors of this type. Direct visualization of the lesion is possible, its precise site and extent can be determined, and biopsy samples obtained for pathology under direct visual guidance.
