Isomorphous and anaplastic (polymorphous) oligodendroglioma

J Szymas, P Gabryel, W Biczysko

    Neurosurgical Review
    |January 1, 1980
    PubMed
    Summary

    This study examines astrocyte-like and giant cells in oligodendrogliomas. Multinucleated cells are key in polymorphous types, possibly due to viral factors.

    Area of Science:

    • Neuro-oncology
    • Cellular pathology

    Background:

    • Oligodendrogliomas exhibit diverse cell morphologies, including astrocyte-like and giant cells.
    • The presence and origin of these atypical cells remain areas of investigation.

    Purpose of the Study:

    • To analyze the morphological characteristics of astrocyte-like and giant cells in oligodendrogliomas.
    • To investigate the association of multinucleated cells with specific oligodendroglioma subtypes.

    Main Methods:

    • Morphological analysis of 22 oligodendroglioma tumor samples.
    • Classification of tumors into isomorphous, anaplastic, and polymorphous types.

    Main Results:

    • Multinucleated cells were identified as characteristic features of the polymorphous oligodendroglioma subtype.
    • A viral etiology is proposed for the origin of multinucleated Langhans-like cells.

    Conclusions:

    • Multinucleated giant cells are a distinct feature of polymorphous oligodendrogliomas.
    • A viral factor may contribute to the formation of these multinucleated cells.
