[A case of rapidly grown pulmonary blastoma].
A 78-year-old woman who had been in a local hospital with a complaint of cough and chest pain was referred to our hospital because a mass 12 cm in size was found in her right lung by a chest X-ray and CT. Within 3 weeks, the tumor rapidly developed to 19 cm in size. Malignant schwannoma of the lung was suspected by a percutaneus lung biopsy and the right upper and middle lobectomy was performed. Histological analysis of the tumor showed a biphasic structure with epithelial and mesenchymal component which was diagnosed pulmonary blastoma. Pulmonary blastoma is very rare, but it may be of benefit for the thoracic surgeon to establish methods of diagnosis and treatment of this disease.
