Pulmonary alveolar microlithiasis with involvement of the sympathetic nervous system and gonads.

Pulmonary alveolar microlithiasis is a relatively rare disease, of obscure aetiology, manifested by the presence of intra-alveolar laminated concretions distributed diffusely throughout the lungs. In all the recorded cases disease has been limited to the lungs and similar lesions have not been observed in other organs or tissues. The findings in a patient in whom lesions identical to those in the lungs were confirmed in the lumbar sympathetic chain and suspected to be present in the testes are recorded.
