Clinical Trial Summary

This is a physiopathological case-control, non-interventional, monocentric study of adult patients with lymphangioleiomyomatosis. The controls are patients followed in neurology at the CHU of Tours for a tuberous sclerosis complex without lymphangioleiomyomatosis, the healthy volunteers are women with neither pulmonary nor renal pathology and recruited at the clinical investigation centre of the CHU of Tours.
