Auer rod
Auer rods (or Auer bodies) are large,
azurophilic and can resemble needles, commas, diamonds, rectangles, corkscrews, or (rarely) granules.[1]
Eponym
Although Auer rods are named for American physiologist John Auer,[2] they were first described in 1905 by Canadian physician Thomas McCrae, then at Johns Hopkins Hospital,[3] as Auer himself acknowledged in his 1906 paper. Both McCrae and Auer mistakenly thought that the cells containing the rods were lymphoblasts.[4]
