Unusual Cause of Pulmonary Mass in Childhood: Pleuropulmonary Blastoma

Pleuropulmonary blastoma is a malignant lungtumor affecting children. Pleuropulmonary blas-toma is a rare entity having an incidence between 0.25-0.5% of all primary lung malignancies that occurs exclusively in children younger than 6years. The tumor usually originates from pul-monary parenchyma, mediastin and pleura andespecially presents as a solitary pulmonary mass in unilateral lung. In this case report, we present a 3.5-year-old boy who was admitted with fever, dyspnea, wheezing, abdominal pain, weight loss and was diagnosed as pleuropulmonary blastoma. As pleuropulmonary blastoma is rarely seen in childhood, relevant literature on pleuropulmonaryblastoma is reviewed.
