title: Hidradenitis suppurativa occurring on the leg.
abstract: The case of a patient with a recurrent, painful ulceration on the lower leg, clinically and histologically resembling hidradenitis suppurativa, is presented. The fact that this site is devoid of apocrine glands supports the concept that apocrine involvement in hidradenitis suppurativa is coincidental and that these glands are involved secondarily. It is suggested that in this patient the pathogenesis of the disease is follicular occlusion rather than selective apocrine poral closure.
