It usually appears as raised, spongy lesions, and typically occurs in children.[1] This honeycomb is a painful inflammatory reaction with deep suppurative lesions on the scalp. Follicles may be seen discharging pus. There may be sinus formation and rarely mycetoma-like grains are produced. It is usually caused by dermatophytes (fungal infections of the skin affecting humans and animals) such as Trichophyton verrucosum, T. mentagrophytes,[1] and Microsporum canis. Treatment with oral griseofulvin common.[1] SymptomsThere may be loss of hair as hair will come out easily.[2] Sometimes, there is growth of organisms.[3] Lymph and fever symptoms may be present. This condition can be mistaken for a case of impetigo.[4] Diagnosis{{Empty section|date=September 2017}}TreatmentUnlike most other manifestations of Tinea dermatophyte infections, Kerion is not sufficiently treated with topical antifungals and requires systemic therapy. Typical therapy consists of oral antifungals, such as griseofulvin or terbinafine, for a sustained duration of at least 6-8 weeks depending on severity. Successful treatment of kerion often requires empiric bacterial antibiotics given the high prevalence of secondary bacterial infection.[5] See also
