cys·tic ad·e·no·ma·toid mal·for·ma·tion

a rare developmental lung-bud abnormality that results in stillbirth, acute progressive respiratory disease of newborns, or protracted childhood pneumonias; combines features of a hamartoma, dysplastic growth, and tumorous growth. Three types have been described, based chiefly on cyst diameters: Type I: up to 10 cm; Type II: less than 1.2 cm; and Type III: less than 0.5 cm.
