Question 11

In a beryllium-sensitized individual, the presence of this finding in lung tissue establishes the diagnosis of chronic beryllium disease

Answer 11

Noncaseating granulomas or monocytic infiltration

Question 12

Constituent of tungsten carbide (“hard metal”) which is likely the etiologic agent of both the interstitial pneumonitis and the occupational asthma that may occur

Answer 12

Question 17

Syndrome of fever, chills, malaise, and occasionally mild wheezing after inhalation of volatilized fluoropolymers such as Teflon

Answer 17

Polymer fume fever

Question 18
