L66.2
Folliculitis decalvans
Clinical Classification Guidelines
Medical Intelligence & Overview
Folliculitis decalvans is a chronic inflammatory condition that affects the scalp, leading to hair loss and damage of hair follicles. It is characterized by inflamed, pustular lesions that can result in scarring and permanent hair loss if not properly managed. The condition primarily targets hair-bearing areas on the scalp and can impact self-esteem and quality of life due to its visible symptoms.
Causes & Symptoms
Clinical Causes: Bacterial infections, often involving Staphylococcus aureus bacteria, are believed to be a significant contributing factor. Possible immune system involvement, where the body's immune response mistakenly attacks hair follicles. Genetic predisposition may make some individuals more susceptible to developing folliculitis decalvans. Environmental factors, such as skin trauma or irritation from hair treatments or styling tools, can potentially trigger or exacerbate the condition. Other contributing factors might include poor scalp hygiene or the presence of skin conditions that compromise the scalp’s integrity.
Key Symptoms: Persistent scalp inflammation involving red, swollen areas. Formation of pustules or pus-filled bumps on the scalp. Itching, burning, or soreness of the affected areas. Progressive hair loss in patches, often with a scarring appearance. Crusting or scaly patches on the scalp surface. In some cases, the affected hair may break off near the scalp, creating uneven hair loss.
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily based on a thorough clinical examination of the scalp, accompanied by a detailed medical history. A dermatologist may perform scalp biopsies or take skin samples for laboratory analysis to identify bacterial presence or inflammatory patterns. Additional tests might include cultures to detect bacterial infections or blood tests to assess immune response and rule out other scalp conditions.
Treatment Protocols: Antibiotic therapy, such as topical or oral antibiotics, to combat bacterial infections and reduce inflammation. Anti-inflammatory medications, including corticosteroids, may be prescribed to control inflammation and immune reactions. Other medications like dapsone or isotretinoin could be considered in resistant cases. Good scalp hygiene, including gentle cleaning and avoiding irritants or harsh hair treatments, can help minimize flare-ups. In some cases, laser therapy or other dermatological procedures may be recommended to reduce inflammation and promote scalp health. Regular follow-up with a healthcare provider to monitor condition progression and adjust treatment plans as needed.
