title: Idiopathic pulmonary calcinosis: a variant of alveolar microlithiasis.
abstract: Diffuse pulmonary calcinosis has been observed in hyperparathyroidism, chronic renal disease, vitamin D intoxication, but has never been reported in the absence of any underlying disease. We report the case of a young man in whom diffuse pulmonary calcifications was found without any underlying disease and whose clinical and histological features suggest a variant or an incomplete form ('forme fruste') of alveolar microlithiasis.
