Pleuropulmonary blastoma in adolescence: A rare tumor beyond first decade of life.

Pleuropulmonary blastoma (PPB) is a unique dysontogenetic and a primitive neoplasm occuring almost exclusively in the first decade of life, as a pulmonary- and/or pleural-based tumor with cystic, solid, or combined cystic and solid features. It is characterized histologically by a primitive, variably mixed blastematous and sarcomatous tissues. These tumors are usually associated with a poor prognosis. However, with a multimodality treatment approach, the survival of the patient can be prolonged. We herein report two cases of PPB in adolescence, a rare presentation beyond first decade of life with a short review of literature.
