The Thyroid Gland01:23

The Thyroid Gland

4.1K
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...

The Parathyroid Glands00:59

The Parathyroid Glands

2.3K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Secondary Lymphoid Organs01:15

Secondary Lymphoid Organs

1.8K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Metastasis02:30

Metastasis

5.6K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Area of Science:

  • Oncology
  • Pathology
  • Surgical Anatomy

Background:

  • Thymomas are neoplasms originating from thymic epithelial cells.
  • Typically found in the anterior mediastinum, thymomas can rarely occur ectopically.
  • Cervical masses are often misdiagnosed as thyroid or parathyroid conditions.

Purpose of the Study:

  • To report a rare case of ectopic cervical thymoma.
  • To emphasize the diagnostic challenge posed by cervical thymomas.
  • To highlight the importance of including thymoma in the differential diagnosis of neck masses.

Main Methods:

  • Case presentation of a 62-year-old female with a cervical mass.
  • Diagnostic workup including imaging and biopsy.
  • Histopathological classification of the thymoma.

Main Results:

  • Diagnosis of ectopic cervical thymoma, type AB.
  • The patient presented with a noticeable neck swelling.
  • Histopathology confirmed thymoma arising from ectopic thymic tissue.

Conclusions:

  • Cervical thymoma is a rare but important differential diagnosis for neck masses.
  • Awareness of ectopic thymoma presentation is crucial for accurate diagnosis.
  • Prompt recognition can prevent misdiagnosis and ensure appropriate management.
