History
First documented in 1980 by Beacham and colleagues, the condition was named "equestrian panniculitis" and is also called "equestrian perniosis" or "equestrian chilblains." A 2011 survey in Finland indicated that about one-quarter of riders experienced related symptoms between October and March. Comparable cases have appeared in cyclists, motorcyclists, and people crossing rivers, especially when wearing tight clothing in cold, damp conditions for long periods. This has prompted debate over whether "cold-associated perniosis of the thighs" is a more fitting term.
