Use of Trichoscopy in Non-Scarring Alopecia in Pediatric Age
Keywords:
alopecias; trichoscopy; children; scalpAbstract
Introduction: Trichoscopy is a diagnostic technique, with dermatoscopic patterns described in non-scarring alopecia. It is not a common practice in Cuba, and there are few studies on the subject. In recent years, an increase in childhood alopecia has been observed at the Provincial Teaching Pediatric Hospital Eliseo Noel Caamano, of Matanzas, and the use of this procedure allowed for a definitive diagnosis of the cases.
Objective: To determine the usefulness of trichoscopy in the diagnosis of non-scarring alopecia in pediatric patients.
Methods: A descriptive, cross-sectional study was conducted in 67 children with alopecia, treated at the provincial pediatric hospital, in the period from February 2021 to May 2023. The information was processed using the SPSS statistical package for Windows, version 16.0.
Results: The age group of 5 to 9 years (49.0%) and male sex (65.7%) prevailed. Among the most observed entities were non-inflammatory tinea capitis (25 cases), and the trichoscopic findings included perifollicular scales (84%), black dots (48%), broken hairs (32%), and corkscrew hairs (28%); alopecia areata (19 patients), where exclamation mark hairs (63%) were observed, and seborrheic dermatitis (16 cases), with a predominance of scales (94%), erythema (50%), and a simple vascular pattern (44%). Clinical/trichoscopic concordance was established, with satisfactory results in this type of alopecia.
Conclusions: It was determined that the technique is useful for the diagnosis of non-scarring alopecia in infants.
