A 13-year-old boy presented to the outpatient department with complaints of breathing difficulty for the past 2 months. Magnetic resonance imaging of the thorax showed a solid cystic mass lesion in the right hemithorax of size 8.9 x 10.7 cm with mild pleural effusion with mass effect shifting the major vessels to the left side. Computed tomography-guided biopsy was done which showed variable thickened nodule-like areas with both single cells and cohesive aggregates with positive stains for vimentin and cytokeratin. A diagnosis of pleuropulmonary blastoma was made. The patient underwent surgical resection and is currently on follow-up. Pleuropulmonary blastomas are rare and aggressive childhood intrathoracic tumors common in children less than 6 years of age. It may be of three types- type I (cystic), type II (mixed), or type III (solid). Clinical presentation includes shortness of breath, chest pain, cough, and hemoptysis. Tumor size >5 cm with pleural or mediastinal invasion has a poor prognosis. Surgical resection, postoperative radiotherapy, and chemotherapy are available.
