title: Pulmonary blastoma.
abstract: A primary pulmonary tumour in a four year old boy arising from the subpleural zone of the lung is described. It contains both stromal and epithelial elements at the primary site and in the bony metastases. The combination of the age of the patient, the site of the tumour, the stromal and epithelial elements present in the tumour suggest that this is a true pulmonary blastoma. Electronmicroscopy showed the presence of intranuclear viral particles.
