Oncocytes in the nasopharynx

R A Erlandson, B Tandler

    Archives of Otolaryngology (Chicago, Ill. : 1960)
    |March 1, 1977
    PubMed
    Summary

    Numerous oncocytes were found in a nasopharyngeal biopsy. Further research is needed to determine if these cells indicate early nasopharyngeal oncocytoma or reactive metaplasia.

    Area of Science:

    • Pathology
    • Cell Biology
    • Otorhinolaryngology

    Background:

    • Nasopharyngeal biopsies are crucial for diagnosing various conditions.
    • Oncocytes are cells with abundant mitochondria, often associated with tumors or metaplasia.

    Observation:

    • A nasopharyngeal biopsy revealed a significant presence of oncocytes.
    • These cells were identified within both the mucosal epithelium and submucosal glands.

    Findings:

    • Ultrastructural analysis showed oncocytes packed with mitochondria, some with rarified matrices.
    • Other cytoplasmic organelles were scarce in these oncocytes.

    Implications:

    • The findings raise questions about the origin of these oncocytes.
    • Further investigation is required to differentiate between early-stage nasopharyngeal oncocytoma and reactive oncocytic metaplasia.
