Abstract
AbstractCongenital pulmonary lymphangiectasia (CPL) is a rare developmental disorder of the lung, characterized by dilation of pulmonary subpleural, interlobar, perivascular and peribronchial lymphatics. The incidence of CPL among stillborn and neonates was estimated to be <1%. The etiology of CPL is unknown. However, it has been suspected to be of a genetic background. Recent basic studies revealed that it might be caused by the FOXC2, Vegfr-3 and integrin α9β1gene mutations. A clinical diagnosis of CPL can be made much easier in full-term neonates who present with respiratory distress, pleural (especially chylous) effusions with or without generalized edema. In infancy, the diagnosis seems to be more difficult due to the nonspecific respiratory symptoms like persistent tachypnea, cough and wheeze. Lung biopsy with subsequent histological and immunohistochemical studies is the golden diagnostic method of CPL. Immunohistochemical staining for endothelial cell markers CD31, CD34 and D2-40 confirms lymphatic origin. Therapeutic strategies include supportive, nutritional, investigational, aggressively interventional and surgical regimens, most of which have shown promising outcomes. Although CPL was once regarded as a disorder of very poor prognosis in neonatal onset cases, teenager and adult patients have shown good outcomes upon long-term follow-up.
