A rare case of posterior mediastinal insular thyroid carcinoma presenting with hyperthyroidism and tracheal compression is described. This is the first reported instance of this specific thyroid cancer subtype causing these severe symptoms.

Area of Science:

  • Endocrinology
  • Thoracic Surgery
  • Oncology

Background:

  • Posterior mediastinal masses can present with diverse clinical manifestations.
  • Thyroid carcinoma, particularly insular subtypes, typically originates in the neck.
  • Hyperthyroidism is a less common comorbidity associated with thyroid malignancies.

Observation:

  • A 57-year-old woman presented with severe cervical compressive symptoms and hyperthyroidism.
  • Computed tomography revealed intrathoracic thyroid tissue invading the posterior mediastinum and displacing the trachea.
  • Pathological examination confirmed poorly differentiated (insular) thyroid carcinoma.

Findings:

  • The case represents the first documented instance of posterior mediastinal insular thyroid carcinoma.

  • The tumor exhibited significant mass effect on the trachea.
  • Concurrent hyperthyroidism was a notable clinical feature.

    • Implications:

    • This case expands the known clinical spectrum of insular thyroid carcinoma.
    • Highlights the importance of considering ectopic thyroid tissue in posterior mediastinal masses.
    • Suggests a potential link between specific thyroid carcinoma subtypes and thyroid hyperfunction.
