ICD-10: L66.4

Folliculitis ulerythematosa reticulata, classified under ICD-10 code L66.4, is a specific type of folliculitis characterized by inflammation of the hair follicles, leading to distinctive clinical presentations. Understanding its clinical features, signs, symptoms, and patient characteristics is essential for accurate diagnosis and management.

Clinical Presentation

Folliculitis ulerythematosa reticulata typically presents as a chronic skin condition that primarily affects the scalp and, less commonly, other areas of the body. The condition is characterized by the following features:

• Follicular Papules: Patients often exhibit small, dome-shaped papules that are usually skin-colored or slightly erythematous. These papules are often grouped and can be mistaken for other skin conditions.
• Reticulated Pattern: A hallmark of this condition is the reticulated (net-like) pattern of the lesions, which can be more pronounced in certain skin types.
• Scarring: Over time, the inflammation can lead to scarring alopecia, where hair follicles are destroyed, resulting in permanent hair loss in the affected areas.

Signs and Symptoms

The signs and symptoms associated with folliculitis ulerythematosa reticulata include:

• Itching and Discomfort: Patients may experience mild to moderate itching in the affected areas, which can lead to scratching and further irritation.
• Erythema: The skin surrounding the papules may appear red and inflamed, indicating an active inflammatory process.
• Pustules: In some cases, pustules may develop, which can rupture and crust over, although this is less common than in other forms of folliculitis.
• Hair Loss: As the condition progresses, patients may notice thinning hair or bald patches in the areas where the papules are most concentrated.

Patient Characteristics

Folliculitis ulerythematosa reticulata can affect individuals of various ages and backgrounds, but certain characteristics are more commonly observed:

• Demographics: It is more frequently seen in individuals with darker skin types, particularly those of African descent. This predisposition may be linked to genetic factors and the unique characteristics of hair follicles in different ethnic groups.
• Age: The condition can occur in both adolescents and adults, but it is often diagnosed in young adults.
• History of Follicular Disorders: Patients may have a history of other follicular disorders or skin conditions, which can predispose them to developing folliculitis ulerythematosa reticulata.
• Environmental Factors: Individuals living in warmer climates or those who frequently wear tight headgear may be at increased risk due to friction and heat, which can exacerbate follicular inflammation.

Conclusion

Folliculitis ulerythematosa reticulata (ICD-10 code L66.4) is a chronic inflammatory condition of the hair follicles that presents with distinctive papular lesions and can lead to scarring alopecia. Recognizing the clinical signs and symptoms, along with understanding patient characteristics, is crucial for effective diagnosis and management. Early intervention can help mitigate the risk of permanent hair loss and improve patient outcomes. If you suspect this condition, a consultation with a dermatologist is recommended for appropriate evaluation and treatment options.

Clinical Description of Folliculitis Ulerythematosa Reticulata (ICD-10 Code L66.4)

Overview
Folliculitis ulerythematosa reticulata, classified under ICD-10 code L66.4, is a specific type of folliculitis characterized by inflammation of the hair follicles. This condition is notable for its distinctive clinical presentation and is often associated with scarring and hair loss.

Etiology and Pathophysiology
The exact cause of folliculitis ulerythematosa reticulata is not fully understood, but it is believed to be related to a combination of genetic predisposition and environmental factors.
