The Metastasis of Human Teratomas

The increasingly successful treatment protocols for gonadal and extragonadal malignant germ cell tumors (MGCT), in particular nonseminomatous germ cell tumors (NSGCT), have stimulated careful clinical and pathological staging (Whitmore, 1979; Vugrin et al., 1979a; Hussey, 1981; Einhorn, 1981), and provided new data on the pattern of metastasis of these neoplasms. Moreover, the gradual acceptance of a more uniform histological classification of germ cell tumors (GCT) regardless of their site of origin (Serov and Scully, 1973; Mostofi, 1977b; Brodeur et al., 1981) has made a review of the recent literature on metastasis of these tumors more feasible.
