Question – What disease was once known as “Salem sarcoidosis”?

Answer- The cited article notes “The first identified cluster of chronic beryllium disease cases ever identified was termed “Salem Sarcoidosis” when former workers from a fluorescent lamp manufacturing plant were found to have a chronic lung disease with features very similar to sarcoidosis. It is of note that chronic beryllium disease and sarcoidosis are histopathologically indistinguishable. (Mayer AS. et al. Sarcoidosis and chronic beryllium disease: Similarities and differences. 2014 Semin Respir Crit Care Med 35: 316-329)
