Kerion is the result of the host's response to a fungal ringworm infection of the hair follicles of the scalp and beard accompanied by secondary bacterial infection(s). It usually presents itself as raised, spongy lesions. This honeycomb is severely painful inflammatory reaction with deep suppurative lesion on the scalp. The follicle may be seen discharging pus. There may be sinus formation and rarely mycetoma-like grains are produced. It is usually caused by Zoophilic dermatophytes such as Trichophyton verrucosum, Microsporum canis and T. mentagrophytes.


Oral Griseofulvin is the treatment of choice.
