Summary
This case report details a rare instance of bilateral lymphoepithelial cysts in the thyroid gland of a 62-year-old woman. The findings highlight the importance of considering these unusual thyroid lesions in differential diagnoses.
Area of Science:
- Endocrinology
- Pathology
- Surgical Oncology
Background:
- Lymphoepithelial cysts of the thyroid are uncommon benign lesions.
- Bilateral presentation is exceptionally rare, making this case noteworthy.
Observation:
- A 62-year-old woman presented with a multinodular goiter and no clinical or biological abnormalities.
- Histological examination revealed multiple thyroid cysts lined by squamous or respiratory epithelium.
- A dense lymphoid infiltrate, chronic thyroiditis, and solid cell nests were also noted in the surrounding thyroid parenchyma.
Findings:
- The study describes a unique case of bilateral lymphoepithelial cysts within a multinodular goiter.
- Histopathology confirmed the presence of cysts with specific epithelial linings and significant lymphoid infiltration.
- Associated findings include chronic thyroiditis and solid cell nests, contributing to the complexity of the lesion.
Implications:
- This case expands the understanding of lymphoepithelial cyst presentation in the thyroid.
- It underscores the need for thorough histopathological examination for accurate diagnosis.
- Further research into the pathogenesis of these rare thyroid cysts is warranted.

01:23The Thyroid Gland
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...

01:23Detailed Structure and Function of Lymph Nodes
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

01:27Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
01:18Lymphoid Cells and Tissues
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

01:27Goiter
Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
