Lymphangioleiomyomatosis (LAM) is a rare multisystem disorder affecting primarily women of child-bearing age, and characterized by cystic lung destruction, tumors of the kidney (angiomyolipomas [AMLs]), and involvement of the axial lymphatics (lymphangioleiomyomas). Patients with LAM experience loss of pulmonary function attributed to the proliferation of abnormal-appearing smooth muscle-like cells (LAM cells). It is possible to group the LAM population by the presence or absence of extrapulmonary involvement (eg, AMLs, lymphangioleiomyomas, chylous effusions). Serum vascular endothelial growth factor (VEGF)-D, a lymphangiogenic factor, is higher in LAM patients than in healthy volunteers and has been proposed as a tool in the differential diagnosis of cystic lung disease. We assessed serum VEGF-D concentrations in relationship to clinical phenotype in LAM patients.
