title: Pulmonary blastoma: report of a case.
abstract: We herein describe a 27-year-old male presenting with a pulmonary blastoma. The patient was admitted to our hospital with the chief complaints of fever and left back pain. Chest roentgenograms showed a tumor measuring 10 cm in diameter in a lower lobe of the left lung. Computed tomography and magnetic resonance imaging revealed a well demarcated and heterogeneously enhanced tumor. Although a histological diagnosis could not be obtained by a transbronchial biopsy, image analyses led us to suspect it to be malignant. The patient underwent a left lower lobectomy with lymph node dissection. A histopathological examination revealed the tumor to be a biphasic type of pulmonary blastoma. Because of the rapid progress of the tumor and the difficulty in making a preoperative diagnosis in such cases, an immediate surgical resection is therefore recommended in cases with even the slightest suspicion of malignancy.
