Arsenic-related hepatic angiosarcoma.

Data from several small autopsy series in German vintners in the 1940s and 1950s and a number of case reports have previously suggested that arsenic is a cause of hepatic angiosarcoma (HAS). In a nationwide review of deaths from HAS in the United States, we identified seven cases with a history of prolonged use of Fowler's solution (inorganic potassium arsenite), which provide further support for the association of arsenic exposure and HAS. An epidemiologic study of a cohort of individuals treated long-term with Fowler's solution might confirm this association.
