A retrospective analysis of lobectomy, pneumonectomy, cystectomy specimens (10 years) and stillbirth/neonatal autopsies (5 years) was carried out to analyze the histologic spectrum of congenital pulmonary developmental disorders/malformations. The autopsy data was analyzed to identify the lesions that are more diffuse and not amenable to surgical management. A total of 166 cases of pulmonary developmental disorders/ malformation were found. Out of 2,155 stillbirth/neonatal autopsies, there were 105 cases of pulmonary hypoplasia, 2 cases of congenital pulmonary lymphangiectasis, 2 cases of extralobar sequestration, and 3 cases of congenital pulmonary airway malformation (CPAM). Among the surgical specimens, there were 21 cases of CPAM, 11 cases of intralobar sequestration, 5 cases of congenital lobar emphysema and 17 cases of bronchogenic cyst. All these malformations have been described in reference to the latest updated classification of developmental disorders/malformations. [ABSTRACT FROM AUTHOR]

We report an autopsy case of congenital pulmonary airway malformation (CPAM) type I occurring within an extralobar sequestrated segment in a neonate with congenital diaphragmatic hernia. [ABSTRACT FROM AUTHOR]
