Summary1 Twelve cases of tumour of the testis in which there was an association of a seminoma and a “teratoma” are discussed and three of these are described in detail. 2 The malignant “teratomata” do not usually show a degree of multi‐differen‐ tiation greater than is seen in many carcinomata in other parts of the body but usually show only an epithelial tissue and often only one form of this. 3 The evidence for the opinion that these are really teratomata is therefore of the slenderest, and the reasons for consider‐ ing that they are not so are discussed. 4 These tumours (both the “teratoma” and the seminoma) are regarded as arising from the cells of the testicular tubules. 5 The term teratoma, by definition, should be applied only to such tumours as show considerable multi‐differentiation and the term should cease to be used as applying to those in which this is not true. For this reason it should not be used for those malignant forms of epithelial growth which differ from the seminomata. 6 Tumours of this kind should be desig‐ nated carcinoma. 7 The seminoma is a carcinoma but, in view of its characteristic features, this or some comparable term should be re‐ tained at present. 8 In this way over 95 per cent. of the growths of the testis, which constitute the malignant epithelial tumours, would fall into two sub‐groups, the carcinoma and the seminoma.
