[Pulmonary alveolar microlithiasis. Apropos of a case]. / La microlithiase alvéolaire pulmonaire. A propos d'un cas.

The pulmonary alveolar microlithiasis is an affection characterized by the presence, in the alveolar light, of calcified deposits or "microliths". It is a rare affection as there is now about 200 cases in the world. We report the case of a pulmonary alveolar microlithiasis discovered in a patient of 25 years old and demonstrated histologically by transbronchial lung biopsy under flexible bronchoscope.
