Sudden neonatal death from congenital cystic adenomatoid malformation

We report a case of congenital cystic adenomatoid malformation (CCAM) of the lungs resulting in sudden death immediately after birth. The case is extremely unusual because of the diffuse bilateral involvement. The extensive involvement of both lungs could explain the abrupt onset of the symptoms and the ineffectiveness of resuscitation attempts. The presence of cartilage as a part of the malformation adds interest to the case, since it is seldom found in this malformation and to the best of our knowledge has been reported only exceptionally in a type II CCAM.
