A young African-American man comes to the office because he has been bothered by the uncomfortable bumps on the back of his neck and lower scalp (Figure 120-1). He likes to wear his hair short but notices that every times he shaves his scalp, the bumps on his scalp get irritated. He is diagnosed with acne keloidalis nuchae. It was suggested that he minimize shaving the scalp and let the hair grow out a bit longer. Additional treatment consisted of 0.025% tretinoin cream and 0.1% triamcinolone cream once to twice daily to the involved area.
