[Congenital pulmonary lymphangiectasis and hyaline membrane. Report of a case]

The case of a newborn with pathological confirmation of congenital pulmonary lymphangiectasis and hyaline membrane is reported. The lymphagiectasis corresponded to type III, with histological characteristics that make it different from other types of lymphatic dilatation. This association is quite uncommon and should be considered in the differential diagnosis of acute respiratory failure in the newborn period.
