Abstract
A pulmonary blastoma is a rare malignant tumor of the lung that is composed of epithelial and mesenchymal elements and resembles the structure of an embryonic lung. Pulmonary blastomas have a very poor prognosis and make up 0.25 to 0.5 percent of all primary malignant lung tumors. A pulmonary blastoma usually manifests as a solitary parenchymal mass or nodule and multiple subpleural mass with effusion on chest X-ray and computed tomography. We encountered a very rare case of pulmonary blastoma in a 52 years old male. He complained of abdominal pain, fullness, and dyspnea. The radiology examination revealed a huge lung mass invading the mediastinum, heart, diaphragm, and liver. The percutaneous needle biopsies were performed, and this tumor was diagnosed as a pulmonary blastoma. We report a biopsy confirmed case of a huge pulmonary blastoma invading multiple organs.
Key Words: Pulmonary blastoma, Lung cancer, Metastasis
