Kerion is the result of the host's response to a fungal ringworm infection of the hair follicles of the scalp (occasionally the beard) that can be accompanied by secondary bacterial infection(s). 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]


There 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]
