Biopsy of intact follicular pustules shows spongiotic vesiculo-pustules affecting the follicular infundibula. Erosive pustular dermatosis of the scalp is a neutrophilic superficial folliculitis, with some clinicopathologic similarities with other pathergic neutrophilic dermatoses, such as pyoderma gangrenosum.
