Résumé

Trichoscopy is a noninvasive technique based on the analysis of hair structures and the scalp, which allows for early diagnosis of different forms of alopecia. We conducted a descriptive cross-sectional study in the Dermatology Department of Hospital Universitario "Dr. José Eleuterio González" in Monterrey, Northeastern Mexico. We included 25 patients with a confirmed diagnosis of leprosy. Ten dermoscopic characteristics were assessed in the eyebrows of these patients. Images of the medial and distal portions of the eyebrows were included. Cohen's kappa coefficient was used for the analysis of coherence between the findings of two dermatologists. Of the 25 patients, 14 were male (56%) and 11 were female (44%), with a median age of 60.28 years (IQR: 40-87). The most common findings in the medial eyebrow included vellus hair (96%) and white-yellowish structureless areas (84%). Furthermore, the most common features of the distal eyebrow included vellus hair (96%), white yellowish structureless areas (92%), and pinpoint white dots (92%). To the best of our knowledge, this study is the first of its kind to describe trichoscopy findings in different leprosy subtypes and classify them into medial and distal eyebrow findings, which seem to be the most affected areas. Identification of these changes is easier in the distal portion of the eyebrows in every subtype of leprosy. We also discovered new trichoscopic findings in the eyebrows: perifollicular hyperpigmentation and yellow dots.

BACKGROUND BACKGROUND
Trichoscopy is a noninvasive technique based on the analysis of hair structures and the scalp, which allows for early diagnosis of different forms of alopecia.
METHODS METHODS
We conducted a descriptive cross-sectional study in the Dermatology Department of Hospital Universitario "Dr. José Eleuterio González" in Monterrey, Northeastern Mexico. We included 25 patients with a confirmed diagnosis of leprosy. Ten dermoscopic characteristics were assessed in the eyebrows of these patients. Images of the medial and distal portions of the eyebrows were included. Cohen's kappa coefficient was used for the analysis of coherence between the findings of two dermatologists.
RESULTS RESULTS
Of the 25 patients, 14 were male (56%) and 11 were female (44%), with a median age of 60.28 years (IQR: 40-87). The most common findings in the medial eyebrow included vellus hair (96%) and white-yellowish structureless areas (84%). Furthermore, the most common features of the distal eyebrow included vellus hair (96%), white yellowish structureless areas (92%), and pinpoint white dots (92%).
CONCLUSIONS CONCLUSIONS
To the best of our knowledge, this study is the first of its kind to describe trichoscopy findings in different leprosy subtypes and classify them into medial and distal eyebrow findings, which seem to be the most affected areas. Identification of these changes is easier in the distal portion of the eyebrows in every subtype of leprosy. We also discovered new trichoscopic findings in the eyebrows: perifollicular hyperpigmentation and yellow dots.
