    Etiology. The cause of the disease is not deter- mined. It occurs about equally in men and women, who usually are over thirty years of age and in poor circum- stances. Sabouraud believes that a seborrhceal skin is the predisposing factor, and that the micro-bacillus is the cause of the disease. The staphylococcus aureus is also found in connection with it. Pathology. J. A. Fordyce’ finds that the disease begins in and about the hair follicles above the entrance of the sebaceous glands. As the infiammatory process extends it involves the sebaceous glands as well as the superficial portion of the derma, resulting in a necrosis of the })ilosebaceous system. In one case he found enormous numbers of staphylococci in the lymph spaces and free in the tissues. Diagnosis. In some cases the resemblance to syphilis is striking, but the extreme chronicity of it and its occiu’- rence along the hair line distinguish it, as well as its general course of development. It differs from acne in leaving varioliform scars, in its sluggish course, and in invading the scalp. Treatment. The ointment of the ammoniate of mercury is efficient in many cases. Sulphur, salicylic acid, and resorcin are also useful. Curetting is also of service. Sabouraud thinks that for the disease when it invades the scalp the best remedy is pyrogallol, either with or without tar or sulphur, fifteen })cr cent, in ointment, or six per cent, in ethereal oil. He also advocates the daily use of alcohol with a little iodine or bichloride of mercury for three months after the disease is apparently well. Crocker speaks highly of the administration of 15 to 25 dro])s of the chloride of iron three titnes a day; and also of iodide of potassium. Acne Necrotisans et Exulcerans Serpiginosa Nasi is de- scribed by Kaposi as an eruption of flabby papules as large as a pin’s head upon the end of tlie nose that soon undergo purulent or necrotic degeneration and leave deep scars. New lesions ajipear and in a few weeks or months the end of the nose is destroyed. ^ Journ. Cutan. and Gen.-Urin. Dis., 1894, xii., 152.
