Erosive pustular dermatosis of the scalp (EPDS) is clinically characterized by a chronic eruption of scalp pustules, erosions and crusts that leads to scarring alopecia. Previous literatures have reported association between EPDS and predisposing factors like skin atrophy and trauma. However, EPDS after childhood burn has never been reported. Three female patients were presented with erosions, crusts, and painful ulceration on the burn scars of the scalp that occurred in childhood. To exclude malignancy on old burn scars, we performed punch biopsies. In all cases, histopathological examination showed infl amed crust, ulcer, acanthosis and neutrophilic infi ltration. Based on the clinical and histopathological features, EPDS has diagnosed. Treatment with clobetasol propionate and 0.1% tacrolimus oint has effect on regression of infl ammatory sign. Although the exact pathogenesis of EPDS is unknown, aberrant wound healing response including insuffi cient blood fl ow, necrosis, or even autoimmunity has been suggested. Healed burn scar is more vulnerable to continued inury, because it has less elastic covering. Repetitive irritation might trigger an autoimmune reaction to unknown skin antigens. Because EPDS has common and nonspecifi c clinical presentation, EPDS could be misdiagnosed. We have suggested when clinicians encounter erosive dermatosis in long standing burn scar, clinicians should consider EPDS in differential diagnosis.
