Abstract
|
|
|
Progressive massive fibrosis (;PMF) as complicated silicosis is present when
conglomerate masses greater than 1 ㎝ diameter are present on the chest radiograph,
while silicosis is the name given to the fibrotic disease of the lungs caused by
inhalation of dust containing silicon dioxide.
Diagnostic difficulties commonly arise at the onset of PMF in excluding carcinoma or
tuberculosis, because of similar X-ray findings. Pathologically, silicotic PMF can be
definitely diagnosed by demonstration of the birefringent particles under polarized light.
We report a case of PMF as complicated silicosis in a 67-year old man with dyspnea.
The chest radiograph showed mass densities on both upper lung fields with increased
interstitial markings and old tuberculous lesions. Clinical diagnosis was lung cancer, but
PMF was confirmed by open lung biopsy.
