Summary

Not all lateral aberrant thyroid tissue is malignant. Histologic examination of nodules and intraoperative assessment can reliably guide therapy, challenging the old surgical dictum.

Area of Science:

  • Endocrinology
  • Surgical Pathology
  • Head and Neck Surgery

Background:

  • Traditional surgical dogma posits that lateral aberrant thyroid tissue signifies metastatic thyroid cancer.
  • This study challenges this long-standing assumption by investigating the nature of such tissue.

Purpose of the Study:

  • To evaluate the histology of "lateral aberrant thyroid" nodules.
  • To determine if these nodules are consistently malignant or if benign ectopic thyroid tissue exists.
  • To inform diagnostic and therapeutic strategies for these findings.

Main Methods:

  • Retrospective review of sixteen cases with ectopic thyroid tissue.
  • Histopathological examination of resected nodules and thyroid glands.
  • Correlation with clinical presentation, including evaluation for hyperparathyroidism and thyroid disorders.

Main Results:

  • Sixteen cases of benign ectopic thyroid tissue were identified.
  • Fifteen cases demonstrated benign histology.
  • Eight thyroid resections revealed either normal thyroid tissue or benign nodules, with no evidence of malignancy.

Conclusions:

  • Lateral aberrant thyroid tissue is not always malignant.
  • Histological assessment of the nodule and intraoperative examination of the thyroid are crucial for accurate diagnosis and treatment planning.
  • The dictum that lateral aberrant thyroid represents metastatic cancer requires revision in medical literature and surgical education.
