Pleuropulmonary blastoma in the area of a previously diagnosed congenital lung cyst: report of two cases

Abstract

Pleuropulmonary blastoma (PPB) is a rare primary malignant pulmonary tumor in pediatric patients. We report the development of PPB in the area of a previous pulmonary cyst in two children, one boy and one girl 5 and 12 years old, respectively. We present the clinical and radiological findings. A short review of the literature is included.
