characterized by subcutaneous nodules located preferentially on the posterior aspects
of the lower legs of adult women. The nodules commonly develop after exposure to cold

provoked by a number of different mechanisms but is most commonly associated with
active tuberculosis (erythema induratum of Bazin).;
