Equestrian perniosis is a skin condition that presents on the lateral thighs of equestrians who ride in cold, damp weather.[1]: 22
Equestrian perniosis lesions appear as red to violaceous patches or plaques on the lateral and posterior thighs and buttocks, often following winter horse-riding in cold, damp conditions.[2][3][4] The lesions may be painful, pruritic, scaly, crusted, ulcerated, or necrotic.[2][4] Associated findings may include Raynaud’s phenomenon and livedo reticularis.[2][3]
Diagnosis
Diagnosis is clinical, based on lesion appearance and history of cold exposure during horse-riding.[2][4] Histological findings are consistent with chilblains, showing vacuolar interface dermatitis with lymphocytic infiltrates, endothelial swelling, and mucin deposition.[4] Blood tests are usually unremarkable.[4]
Management
The primary approach to management is warm, loose-fitting clothing.[2][4] Topical corticosteroids may be used for symptom relief. Oral vasodilators are generally ineffective.[4] Heated pads may offer limited relief. [3]
Lesions typically resolve spontaneously.[2][3]
Prevention
Preventive strategies include avoiding tight clothing, minimizing cold exposure, and wearing insulated clothes during winter riding. Risk factors include being female, young age, smoking, high BMI, prolonged riding, and tight clothing.[2][4][5]
