Ectopic thyroid tissue, presenting as tumors, can cause hyperthyroidism not explained by the normal thyroid gland. This highlights the importance of considering extrathyroidal sources for unexplained hyperthyroidism.

Area of Science:

  • Endocrinology
  • Pathology
  • Cardiology

Background:

  • A case study of an 86-year-old woman presenting with acute myocardial infarction and hyperthyroidism.
  • Initial investigations revealed a lung mass and goiter, with a colonic tumor diagnosed sonographically.

Observation:

  • Autopsy confirmed myocardial infarction with heart rupture and rectal adenocarcinoma.
  • Significant findings included ectopic thyroid tissue in the lung, pelvis, and skeleton, resembling normal thyroid tissue.
  • Histology showed signs of hyperthyroidism in both eutopic and ectopic thyroid tissues.

Findings:

  • The patient's hyperthyroidism was attributed to multilocular ectopic thyroid tissue, not solely the nodular goiter in the normal anatomical position.
  • The lung mass was identified as ectopic thyroid tissue, mimicking a tumor.

Implications:

  • Manifest hyperthyroidism unexplained by normal thyroid findings may indicate ectopic thyroid tissue.
  • This case underscores the need to consider ectopic thyroid tissue in the differential diagnosis of unexplained hyperthyroidism and tumors of uncertain origin.
