[Pulmonary alveolar microlithiasis].

The authors present two of their own observations where, based on the clinical course of the disease and the X-ray finding, they diagnosed the condition as pulmonary alveolar microlithiasis. They present a review of the literature as regards new views on the pathogenesis, diagnosis and therapy of the condition. They evaluate the contribution of scintigraphy 99 mTc, bronchial lavage and X-ray methods with a high differentiating capacity (HRCT). As regards therapeutic possibilities, transplantation of the lungs should be considered in advanced stages of the disease.
