An occupational acnelike skin disorder that occurs after regular contact with chlorinated hydrocarbons. These chemicals are derived from oil and tar products; cutting oils used in engineering also cause the disease. The skin develops blackheads, papules, and pustules, mainly on hairy parts (such as the forearm). Warts and skin cancer may develop after many years of exposure to these chemicals.
Generalized acne that usually occurs after industrial exposure to chemicals such as polychlorinated biphenyls (PCBs) or dioxin.
