Erosive pustular dermatosis of the scalp

Erosive pustular dermatosis of the scalp (EPDS) is a rare chronic inflammatory condition characterized by pustules, erosions, and crusting on the scalp. It primarily affects elderly individuals and can lead to significant scarring and permanent hair loss.

Symptoms

The main symptoms of erosive pustular dermatosis of the scalp include:

• Pustules
• Erosions
• Crusting
• Scaling
• Hair loss
• Pain or tenderness in the affected area

Causes

The exact cause of EPDS is unknown. However, several factors are believed to contribute to its development, including:

• Trauma to the scalp, such as from surgery or injury
• Ultraviolet (UV) radiation exposure
• Previous inflammatory skin conditions
• Immunosuppression

Risk Factors

Several risk factors have been identified for EPDS, including:

• Elderly age
• History of scalp trauma or surgery
• Chronic sun exposure
• Immunosuppressive conditions or treatments

Diagnosis

Diagnosis of EPDS is primarily clinical, based on the characteristic appearance of the scalp lesions. A biopsy may be performed to rule out other conditions such as infections, autoimmune diseases, or malignancies.

Treatment

Treatment options for EPDS include:

• Topical corticosteroids To reduce inflammation.
• Topical calcineurin inhibitors Such as tacrolimus or pimecrolimus, which also help reduce inflammation.
• Antibiotics To treat or prevent secondary bacterial infections.
• Wound care Regular cleaning and dressing of the affected areas.
• Photoprotection Using hats or sunscreen to protect the scalp from UV radiation.

Prognosis

The prognosis for EPDS varies. Some patients may experience chronic and recurring symptoms, while others may achieve long-term remission with appropriate treatment. Early intervention and ongoing management are crucial to prevent complications such as extensive scarring and permanent hair loss.

Prevention

Preventive measures include:

• Protecting the scalp from trauma
• Avoiding excessive sun exposure by wearing hats or using sunscreen
• Regular monitoring and early treatment of any scalp lesions
