Struma ovarii and Brenner tumor

S G Carinelli, F Senzani, I Carinelli

    Tumori
    |December 31, 1981
    PubMed
    Summary

    This study examined a struma ovarii resembling a Brenner tumor. Findings support the germ cell theory for Brenner tumors, linking them to teratomatous elements.

    Area of Science:

    • Gynecologic Pathology
    • Ovarian Neoplasms
    • Germ Cell Tumors

    Background:

    • Struma ovarii is a rare germ cell tumor composed of mature thyroid tissue.
    • Brenner tumors are typically benign epithelial neoplasms of the ovary.
    • The origin of Brenner tumors, particularly their association with germ cells, remains a subject of investigation.

    Observation:

    • A unique case of struma ovarii exhibited epithelial nests identical to those found in Brenner tumors.
    • Direct communication was observed between these Brenner tumor-like nests and ovarian follicles.
    • A single cyst within the tumor displayed a mixed lining of Brenner, mucinous, and respiratory epithelium.

    Findings:

    • The observed histological features, including epithelial nest-follicle communication and mixed epithelial lining, strongly suggest a shared germ cell origin.
    • These findings provide compelling evidence supporting the germ cell theory of Brenner tumor development.
    • The co-occurrence of distinct epithelial types supports the concept of teratomatous elements in Brenner tumor genesis.

    Implications:

    • This case contributes to understanding the histogenesis of Brenner tumors.
    • It highlights the potential for divergent differentiation of germ cells within ovarian neoplasms.
    • Further research into germ cell tumor origins may elucidate the pathogenesis of various ovarian tumors.
