UNLABELLED: Erosive pustular dermatosis of the scalp is a rare inflammatory disorder of the scalp, affecting elderly patients after local trauma and leading to scarring or cicatricial alopecia.

CASE REPORT: An elderly female patient complained of painful pustules on the parietal region bilaterally with progressive enlargement and ulceration.
