Equestrian perniosis: A case report and review of the literature.

Equestrian perniosis is a rare form of perniosis that is predominantly seen in young female equestrians who ride in cold temperatures. Tight fitting clothing, age under 35 years, and smoking can contribute to the disease manifestation. The diagnosis can be determined from a thorough history and physical examination. However, a biopsy can be taken to confirm the diagnosis. Although many cases are self-limiting and resolve within a few days to weeks of diagnosis, nifedipinie can be considered as a therapeutic measure for persistent cases. Measures such as wearing loose fitting clothing and horseback riding in warmer temperatures and for shorter time periods can prevent recurrence.
