Clinical Consequences of Delayed Treatment for Tinea Capitis (Ringworm of the Scalp): A Case Report.

Abstract

A 6-year-old Hispanic patient presented with a 1-month history of pruritic patches on her scalp, characterized by hair loss, black dots, and dandruff-like scales. The patient was seen by her primary care physician, who prescribed ketoconazole 2% shampoo. This provided little relief for her symptoms, which prompted her admission to nearby hospital, where fluconazole was administered intravenously and mometasone lotion applied. The patient was discharged and instructed to use the ketoconazole shampoo and mometasone lotion. The previously prescribed medications failed to improve her now enlarged, inflamed, scaly, pustule-speckled lesions. Given her condition, she was admitted to the University Pediatric Hospital in San Juan, where the Dermatology Department was consulted. Cultures were taken from the lesions, revealing the presence of Trichophyton tonsurans, which led to the diagnosis of tinea capitis (ringworm of the scalp) with kerion formation. In addition, multiple nits and adult lice characteristic of Pediculus humanus capitis were observed. A 6-week course of griseofulvin, a 1-week course of permethrin solution, and a 5-day course of oral prednisolone were started, effectively cleared the patient's inflammation and fungal infection. This case highlights how there exist areas of improvement in terms of interprofessional communication between physicians, as well a need to increase awareness of the proper treatment for this common pediatric skin condition. We postulate that in doing so, similar cases could be spared the unfortunate results of untreated tinea capitis, that is, kerion formation and the possible scarring this lesion can produce.
