Asbestos lichen is a skin disease characterized by the formation of multiple grayish lesions on the skin, reminiscent of traces of skin burns from welding. It can develop on the face, hands, and scalp. In men it is usually observed 4 times more often than in women.
This disease is based on a specific lesion of the peripheral nerve endings of the encapsulated hairy sebaceous glands with hyperplasia of their ducts, resulting in inflammatory infiltrates. The development of the disease is facilitated by a decrease in the body's resistance and changes in metabolism. Predisposing factors may include severe general and general diseases, such as tuberculosis, gastric or duodenal ulcers, alcohol consumption, excessive sweating, and nutritional protein deficiency. Pathological morphology is expressed by thickening of the skin, a decrease in its temperature, expansion of hair follicles and sebaceous ducts and the development of an infiltrate with clinical manifestations of the disease.
