It's something like the eruptions in rubeola.
"Disturbing Sun"
Robert Shirley Richardson
This world is thick with De Boursy-Williamses, throwing in bromides with a liberal hand, ungrudging of strychnine, happily at home with quinine and cathartics, ready at a case of simple rubeola; hideously, secretly, helplessly perplexed between the false diphtheria and the true; treating internal cancer and fibrous tumours as digestive derangements for happy, profitable years, until the specialist comes by, and dissipates with a brief examination and with half a dozen trenchant words the victim's faith in the quack.
"The Dop Doctor"
Clotilde Inez Mary Graves
Have you had any experience with rubeola?
"The Bat"
