Primary chest tumours in children.

Primary chest tumours in children are rare and appear in 3% of cases, 83% of which are malignant. Early diagnosis is very difficult because of delayed symptoms and highly advanced stage. Symptoms of chest tumours depend on the tumour mass, localization and time of progression. These tumours can cause cough, dyspnoea, Horner's syndrome and superior vena cava syndrome. The purpose of this study was to analyze the kind of chest tumours, clinical symptoms before diagnosis, their duration and results of treatment.
