A 10 year old girl named Agatha Christie presents with fever, myalgias, stomach pain, and a rash LIMITED TO THE LOWER EXTREMITIES! (BIG HINT!) Labs show blood in the stool, RBC casts and mild proteinuria. What disease? (HINT: Is it Rocky Mountain or SLE or other?)
A) This is NOT Rocky Mountain or SLE. It is Henoch Schonlein vasculitis! The key words are LOWER EXTREMITIES!
