Erosive Pustular Dermatosis Clinical Management
Summary
Erosive pustular dermatosis (EPD) is a rare, chronic inflammatory skin disorder most frequently affecting the scalp of elderly individuals and often leading to scarring alopecia. The condition typically arises in the context of actinic damage, androgenetic alopecia or cutaneous trauma, and is diagnosed by exclusion of infectious, neoplastic and other inflammatory dermatoses, supported by clinicopathological correlation. Sterile pustules, erosions and crusted plaques characterise the clinical presentation, which can vary from small erosive foci to extensive haemorrhagic lesions. First-line management revolves around high-potency topical corticosteroids, which achieve rapid re-epithelialisation but are frequently followed by relapse upon tapering. Adjunctive and second-line therapies include topical calcineurin inhibitors, systemic retinoids and photodynamic therapy, which have shown promise in maintenance regimens and refractory cases. Recent investigations have emphasised the role of a dysregulated immune response with autoinflammatory features, suggesting overlaps with pustular pyoderma gangrenosum and other neutrophilic dermatoses. Optimal clinical management requires a multidisciplinary approach, combining accurate histopathological assessment, timely intervention to prevent irreversible hair loss and tailored long-term maintenance to minimise recurrence. Understanding the balance between sufficient immunomodulation and minimising treatment-related adverse effects remains central to improving patient outcomes on a global scale.

Technical terms
Erosive pustular dermatosis: A chronic inflammatory skin condition characterised by sterile pustules, erosions and crusts, primarily affecting the scalp of elderly patients.
Scarring alopecia: Permanent loss of hair due to destruction of hair follicles, often the end result of untreated or recurrent inflammatory scalp conditions.
Calcineurin inhibitor: An immunosuppressive agent, such as tacrolimus, used topically to reduce T-cell mediated inflammation without the atrophy associated with corticosteroids.
Photodynamic therapy: A treatment involving application of a photosensitising agent followed by illumination to generate reactive oxygen species that modulate local inflammatory responses.
Androgenetic alopecia: A common form of hair loss influenced by androgen hormones and genetic predisposition, frequently seen as a predisposing factor in scalp EPD.
