Pulmoner Alveoler Mikrolitiyazis: Olgu Sunumu.

Pulmonary alveolar microlithiasis (PAM) is a rare diffuse lung disease characterized by intra-alveolar accumulation of spherical calcium phosphate concretions (microliths). The disease predominates in a few countries, particularly Turkey, Italy, and Japan. Since most of the patients have no symptoms at the time of diagnosis, the disease is usually diagnosed incidentally during pulmonary radiography for other reasons, as in the current case. The SLC34A2 gene mutations can cause PAM. Characteristic radiographic findings of PAM consist of bilateral, fine, sand-like micronodules typically in the middle and lower zones. Although many authors argue that the typical radiological pattern precludes the requirement for a lung biopsy in most cases, it remains the most definitive procedure for confirmation of PAM. There is no known effective treatment for the disease. We present a case of pathologically diagnosed PAM with a review of the literature. [ABSTRACT FROM AUTHOR]
