A 20 year old woman horse rider presented with painful lesions on her outer thighs in the winter months for five years. Examination showed bilateral symmetrical erythematous indurated tender plaques on the lateral aspects of her thighs. Blood investigations, including a vasculitis screen, serum cryoglobulins, and cold agglutinins, were normal. Skin biopsy from the affected area showed features of perniosis with lymphocytic vasculitis. Equestrian perniosis occurs in female horse riders, affecting their buttocks or lateral thighs, with worsening symptoms in cold weather. Wearing warm loose clothes, avoidance of cold, and use of oral nifedipine or pentoxyfylline may be helpful.
