“…An exposure to aliphatic or hydrocarbon solvents, including trichloroethylene, perchloroethylene, toluene, benzene and xylene, and also white spirits, diesel and aromatic mixes, seems to be an important provoking factor for scleroderma-related disorders in different parts of the world [1,[3][4][5][6][7][8][9][10][11][12], including Hungary [5,6,[13][14][15]. Among the solvents trichloroethylene is a considerable provoking factor [6,9,10,13,[16][17][18]. Other agents, such as perchloroethylene, benzene [6,14], other organic compounds including amines [4], and formaldehyde derivatives [4] are also capable of provoking scleroderma.…”
