Mysterious finger rash, solved!

In the good old days, docs could discover new things, and name them after themselves. These are probably thousands of these eponyms: Osler’s Nodes, the Sphincter of Oddi, Rovsing’s Sign, Sinding-Larssen-Johansson Syndrome—there are hundreds of these for doctors to reel off, impressing patients and medical students alike. Names like these aren’t really in style now, but I figure if I find something cool, maybe I can squeeze in one more eponymous disease?

The family was reassured, and the boys were sent back to the pool.

There. Now I am famous. Yay!
