The diagnosis of paraffin-induced interstitial pulmonary disease was established by (1) evidence of massive exposure to aerosolized hot paraffin, (2) interstitial pulmonary disease with progressive constitution of restrictive syndrome, (3) CT scan demonstrating interstitial syndrome and hypodense mediastinal lymph nodes suggesting fat density, (4) light microscopy of open biopsy showing features consistent with lipoid pneumonia […]

Paraffin, a mineral oil, can induce alveolitis and interstitial fibrosis, possibly related to the activation of oil-laden AMs. This lipoid pneumonia is usually related to repeated aspiration of paraffin-containing laxative or nasal drops. We report the first case of a workman suffering from an interstitial pulmonary disease related to occupational par­affin exposure.
