Abstract:
Equestrian cold panniculitis in women.

We describe four patients with panniculitis attributable to a combination of cold
exposure and equestrian activities. All were young, healthy women who rode horses
for at least two consecutive hours per day throughout the winter. Initially,
several small, erythematosus, pruritic papules appeared on the superior-lateral
portions of one or both thighs. During one week, the lesions progressed to
indurated, red-to-violaceous,tender plaques and nodules. Studies for
cryofibrinogens and cryoglobulins were negative. The histologic picture was that
of a panniculitis with prominent inflammation of veins most notable at the
dermal-subcutaneus fat junction. Cold panniculitis is not limited to infancy and
childhood. The distribution of lesions in our patients may have been caused, in
part, by the use of tight-fitting, uninsulated riding pants. Such attire may have
slowed blood flow through the skin, thereby further reducing tissue temperature.
