The Thyroid Gland01:23

The Thyroid Gland

5.3K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Muscles of the Anterior Neck

3.3K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Summary

A rare case of papillary carcinoma was found in lateral aberrant ectopic thyroid tissue, distinct from a healthy native thyroid gland. This highlights the importance of considering ectopic thyroid tissue in neck swellings.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Pathology

Background:

  • Lateral aberrant ectopic thyroid tissue is a rare condition, accounting for 1-3% of all ectopic thyroid.
  • Clinically, these lesions are often misdiagnosed as lymph node swelling or metastatic tumors.
  • Primary carcinoma within lateral aberrant ectopic thyroid tissue, with a normal native thyroid, is exceptionally uncommon.

Observation:

  • A 53-year-old man presented with a large lateral neck swelling.
  • Initial clinical and radiological diagnoses suggested a malignant soft tissue tumor or lymphoma.
  • Fine needle aspiration cytology confirmed metastatic papillary carcinoma.

Findings:

  • Histological examination revealed papillary carcinoma originating in the lateral aberrant ectopic thyroid tissue.
  • The patient's native thyroid gland showed no evidence of malignancy.
  • Surgical management included excision of the mass and subtotal thyroidectomy.

Implications:

  • This case underscores the necessity of including lateral aberrant ectopic thyroid carcinoma in the differential diagnosis of lateral neck masses.
  • Accurate diagnosis and appropriate surgical intervention are crucial for managing this rare condition.
  • Successful treatment involved radioiodine ablation post-surgery.
