Dusting off the numbers of in situ particle analysis: a 35-year experience.

Published

Journal Article

A variety of fibrotic lung diseases are caused by the inhalation of organic dusts. Many of these disorders have distinctive histopathology and can be readily diagnosed by routine histopathologic examination. However, in some instances, there is overlap in morphology between diseases caused by dust inhalation (mineral pneumoconiosis) and other lung diseases. In such cases, analytical scanning electron microscopy (SEM) can provide valuable information to assist the pathologist in making the correct diagnosis. We report herein our findings in 96 cases in which in situ particle analysis (ISPA) was performed with the SEM. This included 56 cases of pneumoconiosis as well as 40 cases of other types of interstitial lung disease. The most common diagnosis for which ISPA was performed in individuals with pneumoconiosis was mixed dust pneumoconiosis (14 cases). The most common diagnoses for which ISPA was performed in individuals with other diseases were sarcoidosis (13 cases) and hypersensitivity pneumonitis (10 cases). In addition to a detailed description of our methodology, we also report other circumstances in which ISPA assists in the diagnosis of pulmonary disease.
