[Lymphangioleiomyomatosis and tuberous sclerosis: a casual association or a causative one?].

Lymphangioleiomyomatosis (LAM) is a rare lung disease that mainly affects women of childbearing age. Pulmonary disease that is indistinguishable from LAM appears in 1% of patients with tuberous sclerosis (TS). At present we can not say whether we are looking at an association of two rare diseases or at a single disease with different clinical profiles. To date, open lung biopsy has been required for definitive diagnosis. We report the case of a women with TS and LAM in whom a diagnosis of pulmonary involvement was based on clinical signs and high resolution computerized tomography of the chest.
