Angiosarcoma of the liver in Great Britain, 1963-73.

Deaths attributed to primary angiosarcoma of the liver (ASL) in Great Britain between 1963-73 were reviewed by submitting available histological material to a panel of histopathologists and by obtaining full occupational and residential histories for the cases agreed as ASL by the panel. On average four recorded cases of ASL occurred a year, but in only one-third of the cases submitted did the panel agree with the original diagnosis. Only one of the agreed cases could be confidently associated with exposure to vinyl chloride.
