Acne can appear in areas in contact with oils and crude tars in certain workers. Men are more often affected than women. The skin may show conspicuous comedones, and only occasionally do frank inflammatory lesions arise; these are usually superficial. Lesions can occur within 6 weeks of exposure on almost any site, but the thighs and lower arms are especially prone. The commonest oils involved are the impure paraffin mixtures used in the engineering industry. Crude petroleum can affect oilfield and refinery workers; workers exposed to heavy coal-tar distillates.
