Common among furriers, dyers, lace makers, packers, cordage makers, thallium workers, auto washers, engravers, etchers, glass makers, miners, sulfide workers, x-ray technicians, string instrument players, tan ners, many others. Deep, patchy bronzing of skin from irritation of lice bite and possibly lice excreta. Diffused white spots, usually over torso and upper extremities representing a patchy sclero derma. Entire skin rough, scaly, thick ened. Usually permanent. Usually involves exposed parts, chiefly fingers, hands, forearms. The reddish or reddish-blue nodules may be as large as 2 cm. in diameter. Sometimes as many as 40 present at one time. Mild systemic disease with lymphangitis, lymphadenitis may appear. Chiefly limited to webs of fingers, or at least to fingers.

Apart from infection, condition rarely disabling. White spots and transverse markings may indicate antecedent disease. Usually associated with low order of personal hygiene. Startling when present on Ne groes or other dark races. Grossly troublesome to owner. Harmless to fellow-workmen. Self-limiting disease. Requires no treatment, but complica tions such as secondary infec tion may require treatment. Burrowing sinuses made trouble some by secondary infection.

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. Pigmented moles are prone to become malignant. {continued) 00
