Equestrian cold panniculitis in women

Area of Science:

• Dermatology
• Sports Medicine

Background:

• Cold exposure can trigger panniculitis, an inflammation of subcutaneous fat.
• Equestrian activities, especially in cold weather, present unique exposure risks.

Observation:

• Four young, healthy female equestrians developed thigh lesions after riding for hours daily in winter.
• Lesions evolved from papules to tender plaques and nodules.
• Histopathology revealed panniculitis with prominent venous inflammation.

Findings:

• Negative results for cryofibrinogens and cryoglobulins ruled out certain cold-related conditions.
• The findings suggest cold panniculitis can occur in adults, not just infants.
• Tight, uninsulated riding pants may exacerbate cold exposure by impairing circulation.

Implications:

• Highlights the risk of cold panniculitis in specific occupational or recreational activities.
• Suggests protective clothing modifications for equestrians in cold climates.
• Broadens the understanding of cold panniculitis etiology beyond childhood.
