Overview
Kerion celsi, also called kerion or tinea capitis kerion, is a severe form of scalp ringworm caused by a fungal infection. Unlike mild ringworm, kerion causes a painful, swollen, boggy lump on the scalp that oozes pus. It happens when the body mounts a strong immune reaction against the fungus, usually from the Trichophyton or Microsporum family. The infection gets deep into the hair follicles, causing significant inflammation. The main symptoms include a raised, soft, tender swelling on the scalp that may feel spongy or boggy to the touch, hair loss in the affected area, pus draining from small openings, crusting, and swollen lymph nodes in the neck. The condition can be quite painful and distressing, especially for children, who are most commonly affected. The good news is that kerion celsi is treatable. Doctors use oral antifungal medicines, most commonly griseofulvin or terbinafine, taken by mouth for several weeks. Topical creams alone are not enough. With proper treatment, most people recover fully, though there is a risk of permanent scarring or hair loss if treatment is delayed. Early diagnosis and treatment are key to a good outcome.
