    In the occipital region a condition known as Acne keloid (Dermatitis papillaris capillitii) occurs, which might be mistaken for syphihs (see page 115). The disease is very chronic. Ultimately hypertrophied scar tissue forms, accompanied by baldness of the area involved, but exhibiting here and there characteristic tufts of hair. In so-called Follicu- litis decalvans, irregular cicatricial areas are formed about the scalp. As a result of secondary syphilitic eruptions, hypertrophic scarring may occur occasionally in severe cases, as a result of ulcerative or rupia-like lesions. Such a complication no doubt results from secondary pyogenic infection. This hypertrophic scarring must be distinguished from true keloid. Hypertrophied scarring has also been noted in Acne vulgaris, Sycosis, Variola, Scrofulodermia, and after Vaccination. On the other hand the papular erup- tive elements may subside leaving an atrophic con- dition behind. Both possibilities must be borne in mind. In shoeing-smiths, small circular scars may occur about the flexor aspects of the forearms, above and below the bend of the elbows, as a result of burns from the sparks as they fly upwards. These should not be taken for syphilis. With regard to the more or less superficial atrophic scar-like conditions, those left behind about the backs of the hands and fingers by Lupus erythematosus, and also by Erythema iris, the latter very faint, may be just mentioned. The superficial scarring and atrophy observed about the hands and knees and
