“…The development of ectopic sites of hair growth that include the complete hair follicle with the bulb and tract have been also reported in the nail bed, something different from the finding of subungual fragments of hair tracts in some occupations such as hairdressing. 31,32 Furthermore, it has been described that hair follicles, experimentally transplanted to the injured spine of mice, produced long hair tracts from the spinal cord. 33 This finding may mean that the presence of chronic trauma can promote the growth of longer hair tracts.…”

Key lesions of pilonidal cysts and hidradenitis suppurativa have similar sonographic morphologic characteristics, which suggests that a pilonidal cyst may be a variant or localized form of hidradenitis suppurativa. The retained fragments of hair tracts frequently detected in both entities may be caused by ectopic production of hair and not by embedding. Common therapeutic strategies and research can be designed for both entities.
