Cystic adenomatoid malformation: Two clinical forms of presentation

Abstract

Cystic adenomatoid malformation (CAM) is a rare disease. It consists in an abnormal proliferation of mesenchymal lung elements secondary to maturation failure of the bronchial structures. It has a series of common pathology characteristics and others that are differentiated, and these are used to classify them. It is sometimes associated to other malformations and can be manifested clinically as: hydrops fetalis, neonatal respiratory distress, and sometimes is silent, even for long periods of time. It can be diagnosed prenatally, although the confirmation requires a pathology study of the lesion. The treatment is surgical. We present two cases of CAM with two different forms of presentation.
