The role of cold exposure in the etiology of perniosis was clearly identified among susceptible individuals. However, few authors have newly reported purple-red “equestrian-type lesions” localized on thighs in patients without equestrian activity and suggested to use the reputation; “cold-induced perniosis of thighs.” We conducted a retrospective chart review of patients who have presented to our department with cold perniosis-like lesions exclusively localized on the thighs. Clinical and histopathological features of five female patients aged 16–31 years without equestrian activity indicated the diagnosis of cold-induced perniosis of the thighs. Cold-associated perniosis may be appropriate diagnosis for the patients presenting with symmetrically distributed painful, itching, or burning violaceous plaques and patches on the thighs for several weeks. The condition primarily affects overweight women and does not require outdoor activity. Microscopic presentation of the disorder is variable and very similar to acral idiopathic perniosis and chilblain lupus erythematosus.
