Henoch-Schonlein purpura (HEN-awk SHURN-line PUR-pu-ruh) is a disorder that causes inflammation and bleeding in the small blood vessels in your skin, joints, intestines and kidneys.
The most striking feature of Henoch-Schonlein purura is a purplish rash, typically on the lower legs and buttocks. Henoch-Schonlein purpura can also cause abdominal pain and aching joints. Rarely serious kidney damage can occur.
Although Henoch-Schonlein purpura can affect anyone, it's most common in children between the ages of 2 and 6. Henoch-Schonlein purpura usually improves on its own. Medical care is generally needed if the disorder affects the kidneys.
