Tuberous sclerosis with pulmonary involvement

Abstract

Pulmonary tuberous sclerosis produced interstitial disease in a woman with normal-sized lungs; numerous hemosiderin-laden macrophages were found in the fluid obtained through bronchoalveolar lavage. The pathological changes seen in the lungs were identical to those of pulmonary lymphangiomyomatosis, in which the constellation of clinical signs usually found in tuberous sclerosis is absent. The two conditions are sufficiently similar in clinical presentation, pathological changes and prognosis to be considered variants of the same disease. The recent findings of progestin receptors in lung tissue from patients with pulmonary lymphangiomyomatosis will likely direct future management towards hormonal manipulation.
