Endocervical polyp with pseudosarcomatous pattern and cytoplasmic inclusions: an electron microscopic study.

J Aneiros Cachaza, J J Lopez Caballero, J Alonso Fernandez

    American Journal of Clinical Pathology
    |May 1, 1986
    PubMed
    Summary

    A rare case of endocervical polyp revealed atypical stromal cells with unique cytoplasmic inclusions. Ultrastructural analysis confirmed these bizarre cells are fibroblastic, resembling infantile digital fibromatosis findings.

    Area of Science:

    • Gynecologic Pathology
    • Cellular Ultrastructure
    • Histopathology

    Background:

    • Endocervical polyps are common benign gynecologic lesions.
    • Atypical stromal cells are rarely reported in endocervical polyps.
    • Understanding cellular morphology is crucial for accurate diagnosis.

    Observation:

    • A case of endocervical polyp in a 32-year-old woman presented with unusual stromal cells.
    • Light microscopy identified eosinophilic cytoplasmic inclusions within these atypical cells.
    • Electron microscopy was employed to elucidate the ultrastructure of these inclusions.

    Findings:

    • Ultrastructural analysis revealed nonmembrane-bound, compact fibrillary structures within the cytoplasm.
    • These inclusions were closely associated with cytoplasmic microfibrils.

    Related Experiment Videos

  • The bizarre stromal cells exhibited fibroblastic characteristics, with inclusions similar to those seen in infantile digital fibromatosis.

    • Implications:

    • This report describes a novel finding in endocervical polyp pathology.
    • The ultrastructural features suggest a potential fibroblastic origin for the atypical cells.
    • This case expands the differential diagnosis for atypical stromal cells in gynecologic specimens.
