Lymphangioleiomyomatosis (LAM) is a rare multi-system disorder affecting predominantly women of childbearing age. The disease entity is divided in sporadic LAM (sLAM) and LAM associated with tuberous sclerosis complex (TSC). In up to 50 % of female TSC-patients pulmonary involvement (TSC-LAM) can be found, with first clinical symptoms usually starting between 25 and 30 years of age. Progressive deterioration of lung function of 3 - 11 % of diffusion capacity per year has been described, that's why all female TSC patients should be screened for LAM (pulmonary function testing, 6-minute walk test, high-resolution chest CT scan). MTOR inhibitors such as Everolimus or Sirolimus are implemented in the treatment of TSC/LAM and found to control disease burden. Screening for all organ manifestations in TSC is recommended and allows to improve prognosis and to prevent complications in TSC.
