Radical resection of a pulmonary blastoma involving the mediastinum

Pulmonary blastoma is a rare primary lung tumour associated with poor prognosis. Despite modern diagnostic imaging and biopsy techniques, the diagnosis is usually not considered initially. A case of a 22-year-old man with a large biphasic left-sided pulmonary blastoma, extending to the mediastinum, is reported. It was treated by pneumonectomy and pericardiectomy with radical tumour resection from the anterior mediastinum, under cardiopulmonary bypass. Adjuvant radiotherapy was used. 3 years postoperatively there is no sign of recurring disease.
