Article Abstract:
A 44-year-old man was diagnosed with desquamative interstitial pneumonitis. Desquamative interstitial pneumonitis is inflammation of the lungs that is caused by a reaction to a variety of substances. The patient was admitted to the hospital with a dry cough, shortness of breath and wheezing. He had been diagnosed with chronic proctitis approximately two years before being admitted to the hospital. He was an immigrant to the US from Haiti and had quit smoking seven years before admission. A series of chest X-rays revealed low lung volumes and patchy opaque areas at the bottom of both lungs. A computed tomographic scan of the chest revealed vesicles in the top portion of the lungs and infiltrates with a ground-glass appearance. A lung biopsy revealed he was suffering from desquamative interstitial pneumonitis. The patient was treated with high-dose prednisone without any improvement. He was changed to experimental treatment with interferon.
