    Summary

    Carotid body tumors can produce pressor amines. This review covers their anatomy, physiology, and pathology, detailing nine new cases, including a malignant tumor with facial nerve paralysis.

    Area of Science:

    • Endocrinology
    • Surgical Pathology
    • Neuro-oncology

    Background:

    • The carotid body is a neuroendocrine organ crucial for cardiovascular regulation.
    • Both normal and neoplastic carotid body tissues possess the ability to synthesize and release pressor amines.
    • Carotid body tumors (CBTs) are rare neoplasms requiring careful diagnostic and management strategies.

    Purpose of the Study:

    • To review the comprehensive aspects of carotid body tumors, including their anatomy, physiology, embryology, and pathology.
    • To present nine new cases of carotid body tumors, highlighting clinical presentations and outcomes.
    • To emphasize diagnostic and management protocols for these tumors.

    Main Methods:

    • Literature review of carotid body anatomy, physiology, embryology, and pathology.
    • Retrospective analysis of nine newly diagnosed carotid body tumor cases.
    • Review of clinical presentations, diagnostic workup (including catecholamine levels and angiography), and treatment strategies.

    Main Results:

    • Carotid body tumors demonstrate the capacity for pressor amine production.
    • Among the nine new cases, one malignant tumor presented with facial nerve paralysis and regional lymph node metastasis.
    • Preoperative assessment included catecholamine level determination and detailed angiographic studies.

    Conclusions:

    • Carotid body tumors are characterized by their potential for amine production.
    • Comprehensive evaluation, including biochemical and radiological assessments, is vital for effective management.
    • Early diagnosis and tailored treatment are essential for favorable outcomes, particularly in malignant cases.
