Acne miliaris necrotica is a type of folliculitis of typically the frontal hairline of the scalp.[2] It presents as multiple small fluid-filled bumps, sometimes occurring as solitary lesions that are typically very itchy and sore.[1][2] Shortly after appearing, the bumps burst and dry up to form crusts.[1] There may be scarring.[1]


The cause may be a result of an inflammatory reaction to part of the hair follicle and S. aureus.[2]


Diagnosis is by visualisation and culture of the lesions.[1]


There are multiple medications that are able to treat acne varioliformis.[3][4]




The condition affects middle aged and elderly individuals.[citation needed]


The condition was first described by Sabouraud in 1928.[5]
