Summary

A massive lingual thyroid, a rare condition, caused severe throat symptoms in a young woman. Surgical removal resolved the issue, preserving normal thyroid function.

Area of Science:

  • Endocrinology
  • Head and Neck Surgery
  • Pathology

Background:

  • Lingual thyroid is a rare congenital anomaly resulting from aberrant thyroid tissue migration during embryogenesis.
  • Massive lingual thyroid presenting with significant airway compromise is exceptionally uncommon.

Observation:

  • A 28-year-old female presented with progressive dysphonia, throat fullness, dysphagia, and dyspnea.
  • Fibre-optic nasopharyngoscopy identified a large, sessile mass obstructing the oropharynx and hypopharynx.

Findings:

  • Histopathological examination confirmed the excised mass to be ectopic thyroid tissue.
  • Post-surgical recovery demonstrated a euthyroid state without the need for thyroxine supplementation.

Implications:

  • This case highlights the importance of considering ectopic thyroid tissue in the differential diagnosis of large pharyngeal masses.
  • Successful surgical excision can alleviate obstructive symptoms while preserving native thyroid function in select cases.
  • Further research into the long-term functional outcomes of lingual thyroid excision is warranted.
