RESUMEN
Congenital cystic adenomatoid malformation (CCAM) of lung is a rare hamartomatous disorder characterized by abnormal branching morphogenesis of the lung. We report an unusual case of a 2-day-old male newborn with a pulmonary cystic lesion and lobectomy revealed a CCAM of the lung that has overlapping features of type 1 and type 2, complicating with multifocal mucinous bronchioloalveolar carcinoma (BAC). The case indicates that malignant transformation can occur in very early stage of the infancy in the patients with CCAM of lung.

Pulmonary sequestration and congenital cystic adenomatoid malformation (CCAM) are individually well known but infrequent congenital malformations of the lung. We report a rare case of pulmonary sequestration and CCAM occurring concurrently in the same infant.
