Keloid-Acne (Dermatitis capillaris papillitii) is a name whichhas been given to an inflammatory folliculitis and perifolliculitis, leav-ing deep infiltrations, usually, in the thick epidermis over the neckand the back of the trunk, though seen also upon the scalp and face.Wisps of thick, distorted, and evidently altered hairs project here andthere from the affected surface. Reddish, and even vascularized nodes,tubercles, and bridges occur at irregular intervals, interspersed withrare acne-pustules and deep-seated, broad, even gigantic comedones.Sclerotic tissue, in brief, forms about the site of the acne-process quitelike cicatricial keloid of the trunk and other situations. Acne Parasitica is a term which eventually will be extended toinclude many of the varieties of the disease described above. Some PLATE II.

The good results obtained by an appro-priate therapy are often the fruit of a destruction of these micro-organisms. That some of these lesions are at times infected with the bacillustuberculosis there can be no question. Not only have tubercle-bacillibeen recognized in the pustules of some forms of acne, but singulardegenerative and even ulcerative results have in rare cases been pro-duced, not solely due to the ordinary processes distinguishable in acne. Ulerythema Acneiforme is probably due in part to a tubercularinfection, and is assigned in this work to another chapter.
