Answer

Ultrasonography of the hair follicles and dermal thickness in hidradenitis suppurativa patients may reveal abnormalities in the deep part of the follicle. In the genitofemoral region, perilesional clinically normal hair follicles have an abnormal shape and are significantly wider in the deep part of the dermis, compared with control samples. Mean axillary and genitofemoral skin is significantly thicker in patients with hidradenitis suppurativa than in healthy control subjects. Thickened skin may play a role in the pathogenesis of hidradenitis suppurativa.
