  • Title: Hormonal bioassay of gonadotropin-producing hepatoblastoma.
    Author: Murthy AS, Vawter GF, Lee AB, Jockin H, Filler RM.
    Journal: Arch Pathol Lab Med; 1980 Oct; 104(10):513-7. PubMed ID: 6251772.
    Abstract:
    Hepatoblastoma was associated with signs of isosexual precocity in an 11-month-old boy. Circulating gonadotropic hormone levels were elevated. Gonadotropic activity was demonstrated by bioassay in extracts of primary and metastatic tumor, and in media surrounding long-term tissue culture of the primary tumor. Morphology of the endocrine glands and bioassay of the pituitary gland obtained at autopsy indicated the presence of gonadotropins and other tropic hormones despite the physiologically abnormal hormone status. These ae the first direct studies of pituitary hormone content in this syndrome.
