Compartment Syndrome: An Uncommon Twist in Childhood Henoch-Schönlein Purpura.

Henoch-Schönlein purpura (HSP) also known as rheumatoid purpura is the most common vasculitis in children. This condition affects small blood vessels, predominantly targeting the skin, digestive system, joints, and kidneys. Short-term prognosis mainly depends on abdominal complications, while long-term prognosis is mainly determined by the severity of kidney involvement, which occurs in about 35% of cases. Although uncommon, other organs such as the lungs, heart, or nervous system may also be affected. Compartment syndrome of the hand and forearm is a very rare complication of HSP. To our knowledge, only two cases have been reported in the literature. We describe the case of a four-year-old child who presented with rheumatoid purpura complicated by compartment syndrome of the hand and forearm successfully managed through emergency fasciotomy.
