A 74 years old male was diagnosed 3 years ago with non small cell lung carcinoma. Accordingly, it was decided that no chemotherapy should be given at that stage. Year and a half later, a new SOL was found in right lung, and right pneumonectomy was performed. On pathology a well to moderately differentiated adenocarcinoma was found. Lymphatic invasion was identified in lung and mediastinum. A revision on previous specimen was performed and it was concluded that the tumor was morphologically different from the previous specimen.
2-year-old girl was diagnosed with pleuropulmonary blastoma (PPB). She presented with cough and fever which was treated as pneumonia. When her symptoms did not improve, a chest X-ray showed a right lower lobe infiltrate with pleural effusion and a cystic lesion superiorly. She was further treated with antibiotics and improved clinically, but follow-up with chest CT showed a persistent cystic area in the right lower lobe and pneumothorax. She thus underwent pleural drainage and thoracoscopic biopsy, revealing a diagnosis of "cystic pleuropulmonary blastoma".
