Erosive Pustular Dermatosis of the Scalp Arising on Long-Standing Burn Scars: A Report of Three Cases and Brief Review of Literature

Introduction: Erosive pustular dermatosis of the scalp (EPDS) is a rare and recalcitrant condition in which chronic scalp pustules and erosive patches are diagnosed by nondiagnostic laboratory tests and histopathological tests. Although various precipitating factors including trauma have been reported, erosive pustular dermatosis arising on the long-standing burn scars is rare. Case Presentation: We report three cases of EPDS arising on long-standing burn scars. Based on clinical and histological findings, erosive pustular dermatosis was diagnosed and successfully treated with topical steroid ointment. Conclusion: We propose that chronic burn scar is another precipitating factors for EPDS and clinicians should consider EPDS in differential diagnoses of erosive pustular dermatosis in long-standing burn scars on the scalp.
