Globotriaosyl ceramide glycolipid in seminoma: its clinicopathological importance in differentiation from testicular malignant lymphoma.
Glycolipids were biochemically extracted from 14 specimens of seminoma, 2 of testicular malignant lymphoma (both of which were difficult to differentiate from seminoma with a high mitotic index) and 4 of normal testicle. The pattern of their expression was compared. Marked accumulation of globotriaosyl ceramide was observed in seminoma but it was present in a small amount in testicular malignant lymphoma. Differentiation between seminoma and malignant lymphoma is sometimes difficult by histopathological findings but it is considered to be greatly facilitated by examination of the pattern of glycolipid expression.
