ICD-10: L66.2

Folliculitis decalvans, classified under the ICD-10-CM code L66.2, is a specific type of folliculitis characterized by inflammation of the hair follicles, leading to hair loss and scarring. This condition primarily affects the scalp and is considered a form of cicatricial alopecia, which is a type of scarring hair loss.

Clinical Description

Definition and Characteristics

Folliculitis decalvans is an inflammatory condition that results in the destruction of hair follicles, leading to patchy hair loss. The affected areas may exhibit pustules, crusting, and sometimes pain or itching. Over time, the inflammation can cause scarring, which permanently affects hair regrowth in the affected regions.

Etiology

The exact cause of folliculitis decalvans is not fully understood, but it is believed to be related to an abnormal immune response to bacteria, particularly Staphylococcus aureus, that colonize the hair follicles. Genetic predisposition and environmental factors may also play a role in the development of this condition.

Symptoms

Patients with folliculitis decalvans may experience:
- Pustules: Small, pus-filled lesions around hair follicles.
- Crusting: Formation of crusts on the scalp due to the rupture of pustules.
- Itching or Pain: Discomfort in the affected areas.
- Hair Loss: Gradual thinning or complete loss of hair in patches, often leading to bald spots.

Diagnosis

Diagnosis is typically made through clinical examination, where a dermatologist assesses the characteristic lesions and hair loss patterns. In some cases, a biopsy may be performed to confirm the diagnosis and rule out other conditions, such as alopecia areata or other forms of cicatricial alopecia.

Treatment Options

Medical Management

Treatment for folliculitis decalvans often involves:
- Antibiotics: Oral or topical antibiotics may be prescribed to reduce bacterial colonization and inflammation.
- Corticosteroids: Topical or intralesional corticosteroids can help decrease inflammation and promote healing.
- Immunosuppressive Agents: In severe cases, medications that suppress the immune response may be considered.

Supportive Care

Patients are advised to maintain good scalp hygiene and avoid irritants that may exacerbate the condition. Regular follow-ups with a dermatologist are essential to monitor the condition and adjust treatment as necessary.

Prognosis

The prognosis for folliculitis decalvans varies among individuals. While some may experience spontaneous remission, others may have a chronic course with recurrent episodes. Early intervention and appropriate management can help minimize hair loss and improve outcomes.

In summary, folliculitis decalvans (ICD-10 code L66.2) is a significant dermatological condition that requires careful diagnosis and management to prevent long-term complications such as scarring and permanent hair loss. Regular monitoring and tailored treatment strategies are crucial for effective management of this condition.
