Perifolliculitis capitis abscedens, classified under ICD-10 code L66.3, is a specific dermatological condition characterized by inflammation of the hair follicles on the scalp, leading to the formation of abscesses. This condition is often associated with painful nodules and can result in scarring and hair loss if not treated appropriately.

Clinical Description

Definition

Perifolliculitis capitis abscedens is a type of folliculitis that primarily affects the scalp. It is marked by the presence of inflamed hair follicles, which can become infected, leading to the development of pus-filled abscesses. This condition is often chronic and can recur, causing significant discomfort and cosmetic concerns for affected individuals.

Symptoms

Patients with perifolliculitis capitis abscedens typically present with the following symptoms:
- Painful Nodules: Tender, swollen lumps around hair follicles.
- Abscess Formation: Pus-filled lesions that may rupture and drain.
- Itching and Discomfort: Patients often experience itching in the affected areas.
- Hair Loss: Scarring from the lesions can lead to permanent hair loss in the affected regions.

Etiology

The exact cause of perifolliculitis capitis abscedens is not fully understood, but it is believed to be related to:
- Bacterial Infection: Often associated with Staphylococcus aureus.
- Follicular Occlusion: Blockage of hair follicles can lead to inflammation and infection.
- Genetic Factors: Some individuals may have a predisposition to developing this condition.

Risk Factors

Several factors may increase the likelihood of developing perifolliculitis capitis abscedens, including:
- Poor Hygiene: Inadequate scalp hygiene can contribute to follicular infections.

Clinical Presentation

Definition and Overview

Perifolliculitis capitis abscedens, also known as dissecting cellulitis of the scalp, is a chronic inflammatory condition that primarily affects the hair follicles on the scalp. It is often associated with scarring alopecia, where hair follicles are destroyed, leading to permanent hair loss in affected areas[1][3].

Patient Characteristics

• Demographics: This condition predominantly affects young adult males, particularly those of African descent. However, it can occur in individuals of any age or gender[1][2].
• Risk Factors: Factors such as genetic predisposition, hormonal influences, and possibly environmental triggers may contribute to the development of this condition. It is also associated with other skin conditions, such as acne and hidradenitis suppurativa[1][3].

Signs and Symptoms

Common Symptoms

1. Painful Nodules: Patients typically present with painful, firm nodules on the scalp. These nodules can become inflamed and tender, often leading to discomfort[1][2].
2. Abscess Formation: The nodules may progress to form abscesses, which can drain pus. This drainage can be spontaneous or may require surgical intervention[3].
3. Scarring: Over time, the inflammation can lead to scarring of the scalp, resulting in hair loss in the affected areas. This scarring alopecia is a significant concern for patients, as it can be permanent[1][2].
4. Itching and Discomfort: Patients may experience itching or a burning sensation in the affected areas, contributing to overall discomfort[1][3].

Physical Examination Findings

• Erythema: The skin overlying the nodules may appear red and inflamed.
• Pustules: Small pus-filled lesions may be present, indicating infection or inflammation around the hair follicles[1][2].
• Hair Loss: Examination may reveal patchy areas of hair loss corresponding to the sites of inflammation and scarring[3].

Diagnosis and Management

Diagnosis is primarily clinical, based on the characteristic appearance of the lesions and patient history. In some cases, a biopsy may be performed to rule out other conditions, such as folliculitis decalvans or other forms of cicatricial alopecia[1][2].

Treatment Options

Management typically involves:
- Medications: Antibiotics may be prescribed to address any secondary bacterial infections. Corticosteroids can help reduce inflammation[1][3].
- Surgical Intervention: In cases of extensive abscess formation, surgical drainage may be necessary. Additionally, excision of scarred areas may be considered for cosmetic reasons[1][2].
- Supportive Care: Patients are often advised on scalp hygiene and may benefit from topical treatments to manage symptoms[3].
