A 45-year-old African-American man had finally decided to seek treatment for the "hair bumps" that had been present on the back of his scalp for 10 years. The patient blamed use of dirty scissors by a barber who had given him a short clipper haircut. He stated that although the rash had begun with a few small bumps, they had increased in number and size over the years and had become a cosmetic problem. The lesions were pruritic and occasionally bled. His medical history included an infection on this region of his scalp, for which he had twice been treated with oral antibiotics.
