What Is Kerion?
Kerion is a kind of fungal infection of the scalp that can cause significant amounts of discomfort and anxiety in individuals who have it. Kerion, also known as kerion celsi, is an acute inflammatory disease that develops when the body reacts to a fungal ringworm infection of the scalp (and occasionally the beard) that may also be followed by a secondary bacterial infection. This disorder is typified by elevated, boggy, and inflammatory lesions on the scalp, which are frequently followed by hair loss (alopecia).
It may appear yellow or crusty with oozing pus. Although the scalp is where they most frequently occur, they can also appear on the face, neck, shoulders, and upper arms. Though adults can be impacted, children are the ones who experience it most frequently. The fungal infection is treated with oral antifungal drugs.
If left untreated, kerions can result in permanent hair loss , alopecia and scarring.
What Can Cause Kerion?
Kerion is a fungal infection that is typically caused by dermatophytes, which are fungi that consume keratin, a protein that is present in the outer layer of skin, hair, and nails. The most frequent fungi that cause ringworms on the scalp are Trichophyton tonsurans, Trichophyton mentagrophytes, Trichophyton verrucosum, and Microsporum canis. There are several ways that these fungi might infect the scalp:
1. Direct Contact: Kerion can be transmitted by contact with an infected person or by sharing contaminated towels, caps, or combs.
2. Animals: Pets like cats and dogs are especially prone to transmitting fungal infections that result in kerion.
3. Poor Hygiene: People living in crowded or unhygienic environments or with poor scalp hygiene may be at greater risk for this infection.
4. Other factors - Additional variables that may heighten susceptibility include compromised immune systems, underlying medical disorders, diabetes, or certain drugs. Kerion is more common in children, especially those with tinea capitis (scalp ringworm).
What Are the Symptoms of Kerion?
The visible sign of a kerion is typically a thick, bumpy, boggy, or mushy nodule on the skin, usually the scalp, or a plaque, which is an elevated, bumpy area more significant than a thumbnail. Its surface typically has several pustules or lumps filled with pus. Pus might ooze from the pustules by breaking them open. Other symptoms of Kerion's include the following:
-
Hair Loss (Localized Alopecia): Damage to hair follicles and inflammation can cause hair loss in and around the afflicted areas.
-
Fever: Fever can sometimes accompany scalp lesions, especially in severe cases.
-
Swollen Lymph Nodes: Inflammation can cause swelling in the lymph nodes behind the ears, on the sides of the neck, and in the back of the head.
-
Dermatophytide: This broad, itchy rash resembles eczema and can occasionally follow fever and malaise.
Kieron's inflammatory nature and the possibility of severe hair loss make it an unpleasant sight. It is critical to distinguish kerion from other scalp disorders like psoriasis or eczema, as they have distinct causes and treatments.
How Is Kerion Diagnosed?
Medical professionals can often diagnose a kerion by taking a complete history and proper physical examination. Sometimes, diagnosing the kerion will be confusing as it mimics many other dermatological conditions. In such instances, the following tests are carried out.
-
KOH Stain—The medical professional carefully scrapes off a small portion of the afflicted area's skin. They might also remove a few hairs or gather pus, which will be studied under a microscope. The slide contains drops of potassium hydroxide (KOH) solution. The KOH solution dissolves the skin cells, allowing the technician to detect the presence of fungi. Usually, the findings are available within a day.
-
Culture - A culture is a material that facilitates the growth of fungus. Fungus culture can be used to identify the type of fungus causing the kerion. A culture yields more precise and targeted results than a KOH strain, but the process can take several weeks.
-
Wood’s Lamp - A unique kind of ultraviolet (UV) light is known as a Wood's lamp. The medical professional illuminates the scalp with a Wood's lamp. Under UV light, ringworms can occasionally glow. The kerion could shine blue, green, or yellow. The medical professional may identify the type of fungus-producing ringworm with a glow.
What Is the Treatment for Kerion?
The main aim of treating kerion is eliminating the fungal infection, reducing inflammation, and promoting scalp healing. Oral antifungal medications can be used to treat keratosis and tinea.
-
Antifungal: Oral antifungal drugs such as Fluconazole, Terbinafine, Isopropanol, or Griseofulvin. The extensive penetration of the fungus into the hair follicle renders topical antifungal medicines ineffective. Treatment usually involves taking oral antifungal medications or syrup for at least 6 to 8 weeks. In certain instances, the healthcare provider may additionally recommend a medicated shampoo, such as Ketoconazole or Selenium sulfide shampoo, to lessen the possibility of the illness spreading to others.
-
Anti-bacterial: The doctor may additionally recommend an oral antibiotic if the child also has a bacterial illness.
-
Anti-inflammatory Drugs: Corticosteroid drugs may be administered to treat inflammation and ease discomfort and itchiness. Powerful drugs like steroids can rapidly reduce the inflammation found in the kerion.
-
Hygienic Habits: It is possible to stop the infection from spreading and returning by practicing good scalp hygiene and refraining from sharing personal objects.
After the infection is treated, hair usually grows back, but in many cases, mainly if the infection has been present for an extended period, hair loss can be irreversible.
Can Kerion Infection Be Prevented?
To prevent kerion, one must take precautions against fungal infections and preserve the health of the scalp:
1. Good Hygiene: To help prevent fungal transmission, wash the hair frequently with a gentle shampoo and refrain from sharing combs, caps, or towels with others.
2. Stay away from Contaminated Items:The risk of infection can be limited by contact with things like pet bedding and shared hair care products that could carry fungus spores.
3. Early Treatment: Fungal infections can be treated early to lessen the chance of complications and stop the progression to kerion, especially in youngsters.
Conclusion:
Kerion is a fungal infection of the scalp that causes hair loss and inflammatory, pus-filled sores. It is mostly found in children and is brought on by fungi called dermatophytes, which feed on keratin. Proper diagnosis and antifungal medication treatment are essential to properly manage kerion and avoid complications.
