    Area of Science:

    • Oncology
    • Pathology

    Background:

    • Multiple myeloma rarely presents with extramedullary plasma cell collections.
    • Extramedullary disease can complicate diagnosis and treatment.

    Observation:

    • The authors describe an unusual case of multiple myeloma revealed by a sub-glottal plasma cell tumor.
    • This presentation is exceptionally rare in the clinical course of multiple myeloma.

    Findings:

    • Histological examination of the sub-glottal mass posed interpretation challenges.
    • Tissue immunofluorescence proved crucial for confirming the plasma cell origin and diagnosing extramedullary multiple myeloma.

    Implications:

    • This case underscores the need for thorough diagnostic evaluation in rare presentations of multiple myeloma.

  • Immunofluorescence is a valuable tool for definitive diagnosis of extramedullary plasma cell neoplasms.
  • Awareness of such rare localizations can improve patient outcomes through timely and accurate diagnosis.
