Pulmonary Blastoma (PB) is a rare primary lung malignancy usually occurring in young to middle aged adults. Surgery is the primary mode of treatment, but survival is poor with the mean 5-year survival being approximately 16%. We report on a case of PB arising in a 63-year-old man. Computed tomography, magnetic resonance imaging and positron emission tomography confirmed the mass to be of pulmonary origin. The morphological appearance combined with the immunoprofile of the tumour was consistent with a poorly-differentiated biphasic pulmonary blastoma. Two months after the surgical resection the patient relapsed with multiple sites of metastasis. The patient was treated with four cycles of cyclophosphamide-, doxorubicin- and vincristine-(CAV)-based chemotherapy, achieving a partial response to treatment. He is currently on a two-monthly review and is recovering from chemotherapy-related toxicities.
