Congenital Adenomatoid Malformation of the Lung

Abstract

An autopsy case of congenital adenomatoid malformation in a newborn female infant who was born after 38 weeks gestational period was reported. This patient had marked cyanosis and respiratory distress immediately after birth, and was dead in 7 hours of age. Adenomatoid malformation was diffuse throughout the entire lungs, and there was no mass effect anywhere. Microscopically myriads of tubular structures lined by cuboidal or cylindrical epithelium were seen, embedded in fibrous stroma in which some smooth muscle and elastic fibers were present. No other gross or microscopic anomalies were observed.
