[Pleuropulmonary blastoma: case report].

Pleuropulmonary Blastoma corresponds to a malignant primary lung disorder, exclusive of pediatric age, infrequent and of aggressive characteristics. Age on diagnosis is 1 month-12 years. Rates per sex are equal. It can be found inside pleura or lungs. Respiratory distress associated or not with pneumothorax, chest pain and fever are classical clinical signs. These symptoms could be misdiagnosed as pneumonia. Radiologically, a large mass near the pleura at the base of the right lung without air bronchogram is its most common form. It has three histological types: type I (cystic), type II (mixed) and type III (solid). Its treatment requires tumor excision and multimodal chemotherapy. Pleuropulmonary Blastoma type I has good prognosis; type II and III variants have lower survival. We report a 2-year-old girl, pointing to the clinicalradiological diagnosis.
