Erosive pustular dermatitis of the scalp

Erosive pustular dermatitis of the scalp (EPDS) is a rare, chronic condition that primarily affects elderly individuals with a history of trauma or surgery to the scalp. It is characterized by sterile pustules, crusted erosions, and atrophic plaques.

Etiology

The exact cause of EPDS is unknown, but it is believed to be related to local immune dysregulation. It is often associated with a history of trauma or surgery to the scalp, including hair transplantation, cryosurgery, and radiation therapy. Other potential triggers include sun damage, skin cancer, and chronic venous stasis. More on etiology.

Clinical Presentation

Patients with EPDS typically present with pustules, crusted erosions, and atrophic plaques on the scalp. The lesions may be painful or pruritic. Hair loss is common in the affected areas. More on clinical presentation.

Diagnosis

Diagnosis of EPDS is primarily clinical, based on the characteristic appearance of the lesions and the patient's history. Biopsy may be performed to rule out other conditions, but the findings are often nonspecific. More on diagnosis.

Treatment

Treatment of EPDS is aimed at reducing inflammation and promoting wound healing. Topical corticosteroids are the first-line treatment. Other options include topical tacrolimus, dapsone, and photodynamic therapy. More on treatment.

Prognosis

The prognosis for EPDS is generally good with treatment, but the condition can be chronic and relapsing. More on prognosis.
