[Disease of metalgrinding workers (author's transl)]

It is a specific clinical picture with extensive soft tissue gas and swelling of the forearm. Usually, the clinical course is without any other symptoms. Therapy is not necessary because gas disappears in few days. The etiology of the disease is not clear. Gas can be generated by the chemical reaction between a metallic foreign body and tissue fluid. Spread of benzine evaporation has been considered as a possible source as well. The disease is very rare and its knowledge is important in differential diagnosis of gas gangrene.
