Pulmonary blastoma is a rare lung neoplasm of disputed histogenesis and variable biologic behaviour. A 31 yr old male presented to the hospital with complaints of breathlessness. Imaging studies revealed a mediastinal mass measuring 11 x 9 x 7cm. Subsequent histopathology on core biopsy revealed a biphasic tumor showing mesenchymal and epithelial components. It is a rare tumor with aggressive behaviour. The case is being presented to make the general histopathologists aware of this rare entity.
