General Discussion

Lymphangioleiomyomatosis (LAM) is a rare progressive multisystem disorder that predominantly affects women of childbearing age. It occurs in women who have tuberous sclerosis, and also in women who do not have a heritable genetic disorder. LAM is characterized by the spread and uncontrolled growth (proliferation) of specialized cells (smooth muscle-like LAM cells) in certain organs of the body, especially the lungs, kidney and lymphatics. Common symptoms associated with LAM include coughing and/or difficulty breathing (dyspnea), especially following periods of exercise or exertion. Affected individuals may also experience complications including collapse of a lung or fluid accumulation around the lungs (pleural effusion). The disorder is progressive and, in some cases, may result in chronic respiratory failure.
