pulmonary blastoma: report of a case and review of the literature

we describe a case of pulmonary blastoma, a rare primary lung malignancy which affects a younger population. this tumor contains both mesenchymal and epithelial elements. pulmonary blastoma tends to relapse locally and metastasizes mainly in the first few years. it has a poor 5-year prognosis, and shows a potentid radio-chemosensitivity. because these tumors are considered malignant, surgical excision is recommended. in this paper, we describe a case of pulmonary blastoma in a 3 year old boy with a brief review of literature.
