[Unusually late debut of lymphangioleiomyomatosis].

The rare, severe lung disease lymphangioleiomyomatosis (LAM) usually presents with dyspnoea on exertion, cough and expectoration in females in the third decade and is worsened by pregnancy or hormone therapy. Lung transplant is often needed within ten years since no specific treatment is available. The patient in this case report was a mother of two, who had never received hormone therapy.
