[Pulmonary alveolar microlithiasis--a clinical case]. / Microlitiaza alveolara pulmonara--caz clinic.

A new case of alveolar microlithiasis is reported, demanding for the diagnosis besides the radio-clinical investigations, complete respiratory function tests, also the pathologic proof. Authors recall the diagnostic approach and our present ignorance of the pathogenesis of this curious entity; no valid therapy is presently able to check the relentless course toward progressive respiratory failure.
