This report details the first known case of lateral aberrant thyroid tissue in the submandibular gland alongside a hypoplastic thyroid gland. This rare finding highlights the importance of considering ectopic thyroid tissue in submandibular masses.

Area of Science:

  • Endocrinology
  • Surgical Pathology
  • Radiology

Background:

  • Ectopic thyroid tissue is rare, with only three reported cases of submandibular thyroid.
  • Simultaneous ectopic submandibular thyroid and a normally present thyroid gland has not been previously documented.

Observation:

  • A 34-year-old woman presented with a long-standing, asymptomatic right submandibular mass.
  • Diagnostic imaging (ultrasound, CT scan) and fine-needle aspiration confirmed hyperplastic ectopic thyroid tissue.
  • The patient's normal thyroid gland was atrophic, with suppressed thyrotropin levels and normal thyroid hormone levels.

Findings:

  • The study identified the first documented case of lateral multiple aberrant thyroid tissue.
  • The case also presented with a hypoplastic thyroid gland, a previously unreported co-occurrence.

Related Experiment Videos

  • Imaging revealed a calcified submandibular mass with cystic areas, distinct from the atrophic normal thyroid.

    • Implications:

    • This case expands the understanding of ectopic thyroid tissue presentation.
    • It underscores the need for comprehensive diagnostic evaluation of submandibular masses.
    • Further research into the embryological origins and clinical management of ectopic thyroid tissue is warranted.
