A case report of pulmonary blastoma confirmed via surgical resection for a massive lung mass

Pulmonary blastoma is a very rare primary lung tumor. We report herein the case of a 54-year-old man with pulmonary blastoma pathologically diagnosed after surgery. He was a heavy smoker and was admitted with dyspnea and coughing. Chest radiography showed a massive pulmonary mass in the left lower lobe and computed tomography scan revealed a 14 cm hypervascular necrotic mass in the same location. A definite pathologic diagnosis could not be obtained using a percutaneous needle biopsy. A left lower lobectomy was subsequently performed and pulmonary blastoma was confirmed following histological examination. The patient received two courses of chemotherapy and radiotherapy for a metastatic brain lesion. In spite of chemoradiotherapy, he had to undergo an operation for newly developed metastatic brain lesion.
