Bean1 recently described circumscript and temporary darkening of graying hair on his scalp at the sites of healed carbuncles. He stated that several correspondents had told him many fascinating things about skin and hair pigmentations and that he had found many scholarly contributions to the subject of hair color, but that he had not come upon any description of such a change as he had observed. This communication has the purpose of supporting Bean's observations in their positive and negative aspect.
Report of a Case
A 62-year-old Negro man was hospitalized at the Veterans Administration Hospital, Dearborn, for chronic generalized dermatitis, considered to be neurodermatitis. While in the hospital he developed a number of furuncles, one of them in January, 1959, on the left posterior aspect of the scalp close to the base of the mastoid. The patient's skin is quite dark, his scalp hair gray due to mixture of about 80% of white hairs with his normally black ones
