What is a Kerion?

A kerion is an abscess of the scalp caused by the fungi Trichophyton, Microsporum and other fungi that normally cause tinea (ringworm). A sore, boggy, raised abscess develops on the scalp and there may be spread of the fungal infection to other areas of the skin. A swab can be taken to identify the responsible fungus, then potent antifungal tablets and creams used to cure the infection.
