title: Pulmonary lymphangioleiomyomatosis associated with pulmonary parenchymal, hilar, and mediastinal noncaseating granulomas.
abstract: A young nonsmoking woman presented with severe dyspnea, exercise desaturation, and chest discomfort. Pathologic and histochemical findings revealed pulmonary lymphangioleiomyomatosis (LAM) as the primary abnormality. In addition, there were multiple noncaseating granulomas with special stains and cultures negative for organisms. This highly unusual combination of pathologic findings might suggest the presence of coexistent sarcoidosis in our patient with LAM.
