Pulmonary hyperplasia

Etiology

laryngeal or tracheal atresia with pharyngotracheal communication

Clinical signs

hydrops
endlarged lungs

Laryngeal atresia, enlarged lungs (73041)

Histology

Histologic appearance of the lung is normal, but the lungs are more mature. In non-communicating forms histology resembles rather CAM, type III.

Case study

Laryngeal atresia

Marta Ježová

History

20-week fetus with hydrops fetalis, enlarged abdomen, striking edema of the head.
