“…The similarity of keratin expression in the non-infundibular epithelium of HS lesions, keratinized or not, to that observed in the outer root sheath suggests that it plays a role in the pathogenesis of HS [27]. An ultrasonographic study of hair follicles in healthy skin of HS patients highlighted their wide diameter and distorted shape and their deep location [28]. Magnetic resonance imaging has been used in some case; it may be helpful in differentiating HS from Crohn's disease or from subcutaneous infection and in preparing for large excisional surgery [29].…”

“…However, quantitatively, this distorted shape with an increase in width difference was statistically significant only in the genitofemoral paralesional follicles, not in axillary ones. 49 Mean axillary and genitofemoral skin thickness and follicular area were also increased in HS patients, though they were statistically significant only in the axillary skin. 49 Jemec and Gniadecka 49 suggest that increased dermal thickness, resulting in alteration of cutaneous mechanical properties, could be a physical factor in HS development or simply the result of chronic inflammation.…”

“…The follicles appear to be of a larger diameter and a distorted shape with a wider deep follicular diameter, in agreement with the clinical impression that the primary event in HS is deep-seated rather than superficial. 102 …”
