BACKGROUND Lymphangioleiomyomatosis (LAM), sporadic or in women with tuberous sclerosis complex (TSC), is characterized by cystic lung destruction, lymphatic involvement (eg, chylous pleural effusions, lymphangioleiomyomas), and renal angiomyolipomas (AMLs). The multisystem manifestations of LAM appear to result from metastatic dissemination of LAM cells(More)
RATIONALE Lymphangioleiomyomatosis (LAM), occurring sporadically (S-LAM) or in patients with tuberous sclerosis complex (TSC), results from abnormal proliferation of LAM cells exhibiting mutations or loss of heterozygosity (LOH) of the TSC genes, TSC1 or TSC2. OBJECTIVES To identify molecular markers useful for isolating LAM cells from body fluids and(More)
LAM is a rare lung disease, found primarily in women of childbearing age, characterized by cystic lung destruction and abdominal tumors (e.g., renal angiomyolipoma, lymphangioleiomyoma). The disease results from proliferation of a neoplastic cell, termed the LAM cell, which has mutations in either of the tuberous sclerosis complex (TSC) 1 or TSC2 genes.(More)
Lymphangioleiomyomatosis (LAM), a rare multisystem disease, occurs primarily in women, with cystic destruction of the lungs, abdominal tumors, and involvement of the axial lymphatics in the thorax and abdomen. To understand the pathogenesis of LAM, we initiated a longitudinal study of patients with LAM; over 500 patients have been enrolled. LAM results from(More)
