Dermatitis accounts for about 30 percent of all illnesses in the workplace. A thorough exposure history is the most important element in accurate diagnosis of skin lesions. In certain cases, skin lesions may be valuable diagnostic clues to the presence of systemic toxicity. Irritant and allergic contact dermatitis, photosensitivity contact dermatitis, and contact urticaria are examples of skin lesions that may be caused by exposure to an environmental agent.
