Fungicide Furunculosis, Chloracne. Pathological sweating. Brick red (warm weather). Plum colored (cold weather). Paroxysmal face and head flushing. Lymphangitis. Keratoses (farmer's warts). Asbestos warts. Tumors (on skin). While causes are multiple, such as "oil furunculosis," a specific type is caused by pentacnlorophenol, an insecticide and fun gicide causing gross furuncules and other skm eruptions. Exposure to certain chlorinated compounds, chiefly waxes. Many nonindustrial causes, but sometimes seen in lead poison ing. Polycythemia(pathologic increase in numbers of red blood cells). Chiefly associated with the meno pause, this type chiefly limited to women 40 to 50. Infection. Excessive sunlight, ultraviolet light .etc. Mechanical penetration by asbes tos fibers; possibly chemical action akin to production of silicotic nodules. Several types, both benign and malignant. Commonest vari ety, epithelioma. New furuncules and acne may arise months after elimination of exposure. Lesions not limited to exposed areas. Secondary infection may be prominent. Characterized by extraordinary numbers of comedones, some times wdth typical acne pus tules. Unusual sweating may be local ized, odoriferous, colored, ex cessive. Sometimes found in heart disease, rickets, syphilis, palsy, tuberculosis, goiter, etc. May be a manifestation of re peated exposure to carbon mon oxide in relatively low concen trations. R. M. I. May be associated with mental depression, excessive perspira tion, weakness, insomnia, emo tional instability. Red streak up arm or.leg. Alarm ing indication of extension of localized .. pyogenic infection. R. M. I. Represent warty, flat, or horny, fieraistent overgrowth of outer ayers of skin. Characteristic of past middle age life; usually limited to exposed parts of skin; characteristic of many trades including farmers, sailors, fish ermen, gardeners, trappers. Condition usually limited to fin gers and hands. Systemic involvement may be associated. In arsenic or lead poisoning, ab normal sweating usually local to parts involved in neuritis. Engorgement and congestion of superficial blood vessels. Most prominent on face. May in volve conjunctivae. Not occupational. Frequently associated with "ker nels" such as in axilla or groin. Rarely become cancerous; readily removed by electrocauteriza tion, by x-ray and by electric needle; less well by keratin solvents. Quite common both in and out of industry. Similar condition with glass fiber workers, but in that case al ways mechanical. Apart from nongrowing warts and obvious abscesses of skin, any enlarging mass on or in skin should be investigated. R.M.I. Pigmented moles are prone to become malignant. (continued) VISIBLE M ABKS OF OCCUPATIONAL DISEASES cS
