Abstract
Background

Follicular vitiligo, a recently proposed new subtype of vitiligo, has primary involvement of the hair follicle melanocytic reservoir.

Objective

We sought to characterize follicular vitiligo through a case series of 8 patients.

Methods

Patients with features of follicular vitiligo who were seen at the vitiligo clinic in the National Center for Rare Skin Disorders in Bordeaux, France, were recruited. A retrospective review of case records and clinical photographs was carried out.

Results

There were 8 male patients with a mean age of 48 years. All patients reported significant whitening of their body and, in some, scalp hairs before cutaneous depigmentation. Examination revealed classic generalized depigmented lesions of vitiligo and an impressive presence of leukotrichia, not only in the vitiliginous areas, but also in areas with clinically normal-appearing skin. Punch biopsy specimen of the leukotrichia and vitiligo lesions demonstrated loss of melanocytes and precursors in the basal epidermis and hair follicle.

Limitations

This was a cross-sectional study based on a single-center experience.

Conclusion

Follicular vitiligo is a distinct entity within the spectrum of vitiligo. This entity may serve as the missing link between alopecia areata and vitiligo, with probable physiopathological similarities between these conditions.
