(lim-fam'jē-ō-lī'ō-nū'ō-mă-tō'sis), [MIM*606690]
A rare disorder of unknown etiology seen in women of reproductive age and in patients of either sex with tuberous sclerosis. Pulmonary complications are due to hamartomatous proliferation of smooth muscle cells preferentially along bronchovascular structures resulting in obliteration of the airways and consecutive development of cysts in the lungs. Usually progressive, leading to death from respiratory failure. Treatment by lung transplantation has been successful.

In fact, TSC provides a good model into the roles of autophagy in human disease but also indicates the possibility of using autophagy inhibition as a therapeutic target, namely, in combination with mTORC1 inhibitors, as was also suggested for lymphangioleiomyomatosis (LAM) [26], a condition also associated with mTOR activation and TSC2 gene mutations.
The indications for LTX were cystic fibrosis in two patients, chronic obstructive lung disease (COPD) in 24 patients, lung fibrosis in 31 patients, lymphangioleiomyomatosis of the lung in one patient, and pulmonary hypertension in one patient.
The lung volume appears to be preserved in chest radiograph, and this feature helps to differentiate PLCH from other (excluding lymphangioleiomyomatosis) interstitial lung diseases that are almost always associated with reduced lung volume.
