Elongated Corkscrew Hairs as a Possible Novel Trichoscopic Sign in Endothrix Tinea Capitis Affecting Adults with Immunosuppression

Résumé fourni par la source

INTRODUCTION: Tinea capitis is a fungal infection of the scalp in which trichoscopy plays an important role by allowing early identification of characteristic hair shaft alterations before mycological confirmation. METHODS: We describe two adult women who are immunosuppressed with endothrix tinea capitis caused by Trichophyton violaceum. RESULTS: Both patients presented with diffuse scalp alopecia and scaling. Trichoscopic examination revealed unusually elongated corkscrew hairs, and fungal cultures confirmed the diagnosis. CONCLUSIONS: Elongated corkscrew hairs represent a previously unreported trichoscopic pattern in chronic endothrix tinea capitis. Awareness of this finding may facilitate earlier diagnostic suspicion and prompt targeted mycological investigation in patients who are immunosuppressed.
