This micrograph depicts the histopathologic changes associated with zygomycosis of the lung, 1965. The infection, due to members of the class Zygomycetes, typically involves the rhino-facial-cranial area, lungs, gastrointestinal tract, and skin. This disease occurs more often in immunocompromised, or burn patients, or those on steroid therapy. Image courtesy CDC/Dr. Martin Hicklin. (Photo by Smith Collection/Gado/Getty Images).
