    Abstract:
    3 cases of congenital pulmonary lymphangiectasis are described. A girl, now 3 years old, underwent at the age of 4 weeks a resection of the left superior lobe of the lung which was singularly involved. A male newborn died 4 h after birth and showed the typical affection of both lungs. A second male infant died 19 d after birth and had an isolated involvement of the left lung. Post-mortem examination additionally revealed in both boys a cardiovascular malformation. Histologically, we especially observed a papillar endothelial hyperplasia in a dilated lymph vessel in case 1 and multinuclear giant cells of the foreign-body type in case 3. In the literature, there are reported 99 cases of congenital pulmonary lymphangiectasis. Including our case, a unilobar or unilateral involvement is described in only 8 cases. The congenital pulmonary lymphangiectasis occurs more often in males than in females (1.8 : 1). 90 out of 93 life-born children suffering from this malformation died, 57 of them during the perinatal period. However, cardiovascular malformations, which were observed in 53 cases, are playing an important role as the cause of death. The aetiology of the congenital pulmonary lymphangiectasis remains unknown. There are 4 different theories concerning the pathogenesis, namely, a persistence of early-fetal lymphatic vessels, a missing connection between primitive lymphatic vessels, a hyperplasia of lymphatic ducts and, last but not least, a passive dilatation of the lymph vessels because of venous or lymphatic congestion.
