erosive pustular dermatosis

Erosive pustular dermatosis of the scalp (EPDS) is a rare inflammatory disease with predominance in the elderly population.

Clinically, the condition is characterized by sterile pustules and chronic crusted erosions. Bacteriologic and mycologic workups tend to have negative findings, and histopathologic evaluation findings are nonspecific.

Affected areas undergo a continuous cycle of healing and recurrence, resulting in atrophic skin with new areas of pustules and erosions. If left untreated, these areas may progress and result in scarring alopecia or cutaneous malignancies.

Although the exact etiology remains unknown, EPDS tends to occur in areas of cutaneous atrophy because of numerous etiologies such as long-standing solar damage, surgical/medical/physical trauma, or, in the case of our patient, a burn.

Although EPDS has been documented after skin grafts in elderly patients, to the best of our knowledge, it has yet to be described in a pediatric patient after skin graft for a burn.
