Abstract
A primary intracranial HCG[human chrionic gonadotropin]-producing tumor was studied in an 8 yr old boy with congenital adrenal hyperplasia. The case provided a unique opportunity to study the sequential changes in serum and urinary androgens and HCG as measured by radioreceptor assay for HCG and radioimmunoassay for HCG using antisera raised against the hormone specific for the .beta.-subunit of HCG. Plasma concentrations of HCG, measured by the radioreceptor assay, closely correlated with the biologic activity of his tumor, as measured by serum testosterone concentration. Precocious puberty in any child, including one with a known androgen disorder such as congenital adrenal hyperplasia, warrants thorough investigation.
