Folliculitis keloidalis (FK) is a chronic inflammatory condition that affects the hair follicles on the back of the neck and scalp. It is characterized by the formation of keloid-like scars, which can be itchy, painful, and unsightly. Folliculitis keloidalis (FK) is a chronic condition characterized by the formation of small, raised bumps or keloids on the back of the neck, scalp, or other areas where hair grows. The exact cause of FK is not known, but it is believed to be related to irritation and inflammation of the hair follicles.
Causes
The exact cause of FK is unknown, but it is thought to be related to a combination of factors, including:
- Genetics: FK tends to run in families and is more common in people of African descent.
- Trauma: Constant friction or irritation of the hair follicles, such as from tight hairstyles or clothing, may contribute to the development of FK.
- Bacterial infection: Folliculitis caused by bacteria such as Staphylococcus aureus may lead to the formation of keloid-like scars.
Symptoms
- Small, red bumps around hair follicles
- Itchy, painful skin
- Keloid-like scars, which can be raised and have a shiny appearance
- Pus-filled bumps or boils
- Hair loss in the affected area
It is important to consult a dermatologist for proper diagnosis and treatment. Treatment options may include topical or oral antibiotics, topical or intralesional steroid injection, laser therapy and surgery.
Diagnosis
FK is typically diagnosed based on a physical examination of the affected area. A skin biopsy may be performed to confirm the diagnosis and rule out other conditions.
Treatment
Treatment for FK may include:
- Topical medications: Topical creams, lotions, or ointments containing steroids or antibiotics may be used to reduce inflammation and itching.
- Oral medications: Oral antibiotics or corticosteroids may be prescribed to help control the inflammation.
- Laser therapy: Laser therapy can be used to reduce the size of the keloids and improve the appearance of the affected area.
- Surgery: In some cases, surgery may be necessary to remove the keloids.
- Preventive measures: Keeping the affected area clean and avoiding tight hairstyles or friction can help prevent further irritation.
It is important to consult with a dermatologist for an accurate diagnosis and personalized treatment plan, as FK can be difficult to manage and may require a combination of treatments to achieve the best results.
