Estelito mendoza law firm. Pulmonary alveolar microlithiasis pam is a rare pulmonary disorder characterized by the accumulation of calcium phosphate microliths within the alveoli with only a few cases described in animals. Pulmonary alveolar microlithiasis is a rare autosomal recessive disease where there is formation of intra alveolar calcium phosphate microliths building up gradually over time. A case of pulmonary alveolar microlithiasis pam with pleura calcification and nephrolithiasis is reported.

At necropsy numerous multifocal to coalescent protruding nodules of 15 mm. Pam is caused by inactivation of the gene slc34a2 due to which the alveolar type ii cells are unable to clean up the phosphorus ion from the alveolar space resulting in its accumulation forming. Pulmonary alveolar microlithiasis is believed to be due to a mutation in the slc34a2 gene that causes inactivation of a sodium dependent phosphate cotransporter which is found mainly in alveolar type ii cells.

Pulmonary alveolar microlithiasis pam is characterized by the widespread intra alveolar accumulation of innumerable minute calculi called microliths. Extrapulmonary calcification in multiple sites raises the possibility of pam being a systemic disorder. Pulmonary alveolar microlithiasis pam is a rare pulmonary disorder characterized by the accumulation of calcium phosphate microliths within the alveoli with only a few cases described in animals.

A 10 year old female bulldog. Pulmonary alveolar microlithiasis pam is a rare parenchymal lung disease caused by variants in the scl34a2 gene and characterised by the accumulation of intra alveolar microliths. Its true prevalence is unknown with about 500 case reports in the literature.

In summary concurrent diagnosis of pam and pleural mesothelioma is made in an adult spayed female bulldog. This cotransporter normally clears phosphate from degraded surfactant. A 10 year old female bulldog was euthanized due to history of dyspnea and recurrent pleural and pericardial effusions.

The significance of peripheral white lines a rarely reported observation on chest roentgenogram in pam is discussed. Pam has been reported in fewer than 1100 cases throughout the world. Pulmonary alveolar microlithiasis is a disorder in which tiny fragments microliths of calcium phosphate gradually accumulate in the small air sacs alveoli of the lungsthese deposits eventually cause widespread damage to the alveoli and surrounding lung tissue interstitial lung disease.

The diagnosis of an epithelioid pleural and pericardial mesothelioma with associated pulmonary alveolar microlithiasis was made based on the characteristic gross histological and immunohistochemical findings. People with this disorder may also develop a persistent cough and difficulty breathing dyspnea. Pulmonary alveolar microlithiasis pam is a rare genetic lung disease characterized by calcifications within the alveoli.
