We report an unusual presentation of PAM in a 10 year old girl with clinically significant interstitial lung disease and histological evidence of both PAM and lymphocytic interstitial pneumonitis. A rapid improvement of pulmonary function and exercise tolerance was seen in response to glucosteroid therapy. ER -
