Abstract:
14 workers in the 1, 8-diaminonaphthalene workshop of a chemical company in Nantong City had symptoms or signs of varying degrees of pruritus and pigmentation of the face, neck and waist. Pathological examination of skin biopsies showed hyperkeratosis, the basal cells were liquefied and denatured. Seven workers were eventually diagnosed with occupational melanosis. To explore the causes of occupational melanosis caused by exposure to 1, 8-dinitronaphthalene and 1, 8-diaminonaphthalene, and to provide reference for the prevention and treatment of occupational melanosis in the future, this paper reported 14 cases of melanosis in the skin of workers in chemical industry.
