ABSTRACT
Controversy continues regarding what level of serum and/or cerebrospinal fluid (CSF) human chorionic gonadotrophin-beta (HCGß) is consistent with pure germinoma of the central nervous system (CNS). We report a 10-year female with biopsy-proven pure germinoma and normal serum and CSF HCGß who experienced subsequent biopsy-proven recurrences of germinoma. At recurrence, serum and CSF HCGß levels were 560 and 3,202 mIU/ml, respectively, although final autopsy demonstrated pure germinoma. This case illustrates the need to re-evaluate the assumption that pathologically pure germinomas may be associated with high levels of HCGß which are unrelated to nongerminomatous germ cell tumor (NGGCT)/choriocarcinomatous elements.
