Teflon granuloma mimicking a thyroid tumor.

R A Wilson, W S Gartner

    Diagnostic Cytopathology
    |June 1, 1987
    PubMed
    Summary

    A patient developed a suspicious thyroid nodule after Polytef vocal cord injection. Histology revealed a benign granulomatous lesion with Teflon particles, not cancer.

    Area of Science:

    • Otolaryngology
    • Pathology

    Background:

    • Vocal cord augmentation is performed for phonation impairment.
    • Polytef (polytetrafluoroethylene) is a synthetic material used for injection augmentation.

    Observation:

    • A patient developed a thyroid nodule after Polytef injection into the left posterior vocal cord.
    • Fine-needle aspiration cytology suggested malignancy.
    • Histological examination revealed a benign granulomatous lesion containing Teflon particles.

    Findings:

    • The "thyroid" nodule was a reactive granulomatous process.
    • Teflon particles were identified within the lesion.
    • The initial cytology was a false positive for malignancy.

    Implications:

    • This case highlights a rare complication of Polytef vocal cord injection.
    • It underscores the importance of correlating cytological findings with clinical history and histological examination.
    • Awareness of this potential benign reaction is crucial for accurate diagnosis and patient management.
