Bronchioloalveolar carcinoma in a child with congenital cystic adenomatoid malformation

An 11-year-old girl was evaluated for chest pain, and chest radiographic findings of multiple nodules throughout both lungs. She underwent resection of several of the lesions from her left lung, which were found at pathologic examination to be bronchioloalveolar carcinoma. Her previous medical history included incomplete resection of a type I congenital cystic adenomatoid malformation in the neonatal period. To our knowledge, this girl is the youngest reported case of bronchioloalveolar carcinoma in a nonimmunocompromised patient, and one of several in which the association of congenital cystic adenomatoid malformation and bronchioloalveolar carcinoma has been observed.
