Double tumours of the liver following intravenous thorotrast injection. Patho-anatomical report on two cases.

Observations on the contrast between the livers of two patients who underwent an arteriogram with thorotrast in 1941 have been made. The first case produced a cholangicellular carcinoma (CCC) in addition to atypical proliferations of sinusoidal lining cells. The second case produced a very rare tumour combination of a CCC with a haemangioendothelial sarcoma (Haem-SA the problem of double tumours of the liver following thorotrast injection is discussed in the light of these cases. In addition the discussion includes various opinions on Kupffer cells.
