Role of trichoscopy in the management of tinea capitis in two infants: A case report

Tinea capitis in newborns: Report of a case and review of the literature with a focus on treatment modalities

Tinea capitis is a common disease in children but rare in newborns younger than 1 month of age. Only 29 cases of tinea capitis in newborns have been described in indexed literature from 1990 until now. While antifungal agents can be used topically and systemically, systemic antifungal therapy is generally accepted as the treatment of choice for tinea capitis due to limited penetration of topical agents into the hair follicle. However, there is a lack of data on the use of systemic antifungal agents in newborns, and there are reports of successful treatment of tinea capitis in newborns using only topical therapy. In this paper, we present a case of tinea capitis in a 29-day-old female baby and review the previous 29 reported cases.

Tinea Capitis in Children Younger than Two Years Old: A Retrospective Study and Treatment Recommendations

BACKGROUND

Tinea capitis (TC) is a dermatophytosis of the scalp and hair, which occurs less common in children younger than two years of age, and the data of TC in this age group are still unknown.

OBJECTIVES

We aimed to reveal the epidemiological, clinical and mycological characteristics of TC in children under two years old.

METHODS

We retrospectively analyzed all reported cases of TC in children in their first two years of life from 1991 to 2022, by searching PubMed, Embase, Web of Science, CNKI, Wanfang and Weipu databases.

RESULTS

A total of 47 articles involving 126 cases of pediatric TC were enrolled in this study. The sex ratio (M/F) was 1.28:1. The age of the children ranged from ten days old to two years old with a median age of three months. The main clinical manifestations were alopecic patches (40 cases, 31.7%) and scaling (39 cases, 31.0%) on the scalp, and 29 infants (23.0%) appeared kerion. The most common sources of contagion were animals (35 cases, 27.78%) and humans (31 cases, 24.60%). The leading pathogens were Microsporidium canis (64 cases, 50.79%), followed by Trichophyton violaceum (13 cases, 10.32%), T. mentagrophytes complex (12 cases, 9.52%) and T. tonsurans (10 cases, 7.94%). Ninety-five children (75.40%) were treated with systemic antifungal drugs and 22 patients (17.46%) were only treated with topical therapy. Except for 10 patients with unknown final prognosis, all the other cases were cured after treatment. There was one child (0.79%) relapsed after treatment with griseofulvin and one case (0.79%) presented with gastrointestinal symptoms from griseofulvin.

CONCLUSION

The principal clinical symptoms of TC in children less than two years old were alopecic patches and scaling. The top four pathogens were M. canis, T. violaceum, T. mentagrophytes complex and T. tonsurans. Oral treatment for pediatric TC had achieved good therapeutic effects, and topical therapy can be an alternative choice.

A Prospective Clinical and Trichoscopic Study of Tinea Capitis in Children during Treatment

BACKGROUND

Tinea capitis (TC) is the most common dermatophyte infection in children. Fungal culture; although a gold standard of diagnosis, requires time for the final results which can favor horizontal transmission. Trichoscopy helps in rapid diagnosis and could work as a monitoring tool during antifungal therapy.

AIM OF THE WORK

The objective of this study is to provide a clinico-trichoscopic evaluation and follow-up of children presenting with tinea capitis during treatment with either griseofulvin or terbinafine.

PATIENTS AND METHODS

One hundred and twenty children clinically diagnosed with tinea capitis confirmed by potassium hydroxide microscopy, were divided into two groups and given either oral ultramicrosize griseofulvin (60, Group A) or terbinafine (60, Group B).

RESULTS

Following initiation of the antifungal therapy, trichoscopic features within groups A and B were noted at 0, 2, 4, 6 and 8 weeks. However, variation in the baseline trichoscopic features between the two groups was not statistically significant (p = 0.855). A significant reduction of corkscrew and broken hairs as well as perifollicular scales, scalp erythema and crust was significantly observed from 2 weeks onwards irrespective of the antifungal drug prescribed.

CONCLUSION

Despite the paucity of data evaluating trichoscopic features in patients with tinea capitis, this tool can serve as a rapid diagnostic and monitoring tool during antifungal treatment. Trichoscopic signs of tinea capitis resolution occur before clinical improvement and can guide for treatment adjustment during the course of therapy. This article is protected by copyright.
