Treatment1
Antiseptic or tar containing shampoos may help to prevent secondary bacterial infections.[3] If symptoms are mild, applying clindamycin lotion or a steroid combined with a retinoid may help.[3]
Treatment2
Injecting the steroid triamcinolone may reduce the size of bumps.[3] Cryotherapy may soften them.[3]
Treatment3
A long course of anti-inflammatory antibiotics such as doxycycline, minocycline, and tetracycline, or oral retinoids may be useful.[3]
Treatment4
Other options include removing the hair follicle via a punch biopsy, cutting out a larger area of affected skin, and laser or light therapy.[3]
Outcome
The condition does not generally resolve.[3]
Epidemiology
The condition is generally common but rare in males older than 55-years.[3] Most occur in men of African descent.[3]
