[Amalgam deposit in a gastric leiomyosarcoma. Case report of an unusual amalgam constellation].

We report an a 57-year-old man with gastric leiomyosarcoma containing depositions of amalgam that possibly originate from a swallowed filling. The significance of this finding remains unclear. This case does not permit any conclusions as to whether this is a coincidence or not. The worldwide use of amalgam without an increase of oral sarcomas/leiomyosarcomas speaks against the supposition that amalgam induces sarcomas.
