Primary mediastinal tumours.

, 475-481. A review of 28 patients with primary mediastinal tumours seen over a five-year period is presented. Clinical and pathological features of a heterogeneous group of tumours are emphasized. Since a number of patients presented with mild symptoms or were asymptomatic (especially adults), the importance of routine chest radiographs is stressed. Complete excision was accomplished in all patients with benign lesions. Malignant lesions were usually partially resectable and carried a poor prognosis.
