four-year-old, white female child was referred to the emergency department for slight chest pain, cough, and a history of low-grade fever in the previous days. Chest radiography showed a hypertensive right pneumothorax associated with complete atelectasis of the lung. A chest tube was positioned with complete resolution of pneumothorax, and the patient was discharged after 5 days.

positioned. A computed tomographic scan was then performed showing a multilocular aerial cyst (Fig 2A) with a caudal solid parenchymatous part (Fig 2B) arising from the lower and middle lobe. After multidisciplinary discussion, the patient underwent surgical intervention performed with a right thoracotomy; two aerial cysts were found arising from the middle and lower lobes. Inside the larger one, whiteyellow, soft parenchymatous areas were found. Frozen section specimen revealed malignant spindle cells. A wide wedge resection of lower and middle lobes was performed (Fig 3). The patient recovered with an uneventful postoperative course. The final diagnosis was type II pleuropulmonary blastoma (Fig 4; hematoxylin and eosin stain, 10), and the patient was referred to the pediatric oncology department.
