To the editor: I read the paper by Cordes and associates (1) in the December issue and the accompany thing editorial by Rosenstock (2) on occupational medicine with both interest and concern. The description of three subjects with a bizarre pneumonia is of interest: it includes however, several errors, and their unjustified speculation detracts from their message. In Patient 1 the lungs are said to contain numerous marcophages containing hemosiderin. Welding fumes contain iron oxide, not hemosiderin! We are told that eight dust samples exceeded the standard of the National Institute for Occupational Safety and Health (NIOSH) for free silica.
