[Benign and semi-malignant lung tumors--Review of a ten-year period]

Benign tumors of the lung are infrequent diseases. Their symptoms depend on their localisation in the periphery of the lung or in the central airways. Cough, hemoptysis, and dyspnoea are the most frequent symptoms, they should cause further diagnostic investigations (X-ray in two directions, bronchoscopy). This paper shows the frequency, symptoms, diagnostic procedure and findings, and the treatment of benign lung tumors, giving a survey of the patients of a pneumologic clinic during ten years.
