An Unusual Case of Tinea Capitis Presented as Erythematous, Hyperkeratotic, Scaly Plaque with Alopecia

A 45-year-old immunocompetent woman presented with an unusual case of tinea capitis, characterized by a non-itchy, erythematous, hyperkeratotic, scaly plaque with partial alopecia on the scalp. Despite the rarity of tinea capitis in immunocompetent adults, especially with alopecia, the diagnosis was confirmed through histopathological examination revealing abundant fungal spores. The patient was successfully treated with itraconazole for 8 weeks. This case highlights the importance of considering tinea capitis in adults with inflammatory scalp disorders unresponsive to conventional treatments, as misdiagnosis can lead to unnecessary interventions.
