Abstract

Background: Kerion celsi represents the inflammatory extreme of tinea capitis, as a delayed hypersensitivity reaction to the causative dermatophyte. Data regarding prevalence, trends in pathogens, and risk factors for scarring are limited.

Objective: The main objective of the study is to assess clinical and epidemiologic features of children with kerion celsi and risk factors for scarring.

Methods: We reviewed medical records of pediatric patients with kerion celsi treated between January 2006 and July 2020.

Results: Among 80 patients, the prevalence of permanent alopecia was 27.5%. Patients with remaining alopecia presented to our clinic at a mean 1.3 months earlier than those with complete response to treatment (2.2 ± 2.1 and 3.4 ± 4.8, respectively; p < .05). Patients of Ethiopian ethnicity were more represented than in the general population; however, scarring was observed in only 11% (p = 0.08). Outcomes did not differ by pathogen, antifungal treatment prescribed, duration of treatment, or the use of prednisone or antibiotics.

Conclusions: Scarring alopecia is a common complication of kerion celsi. Host innate immune response, pathogen virulence, and treatment timeline should be considered as possible variables affecting risk of scarring in the future studies.
