Simplified Synchronous Machine Model01:30

Simplified Synchronous Machine Model

759
The Synchronous Machine Model is a fundamental tool in analyzing and ensuring the transient stability of power systems. This model simplifies the representation of a synchronous machine under balanced three-phase positive-sequence conditions, assuming constant excitation and ignoring losses and saturation. The model is pivotal for understanding the behavior of synchronous generators connected to a power grid, particularly during transient events.
In this model, each generator is connected to a...

Exocrine Glands: Unicellular and Multicellular Glands

32.3K
Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...

The Thyroid Gland01:23

The Thyroid Gland

6.8K
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 Mammary Glands

2.1K
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

The Pituitary Gland01:17

The Pituitary Gland

10.3K
The pituitary is a small endocrine organ in the sphenoid bone under the hypothalamus. Primarily, the pituitary in adults has two distinct anatomical and functional regions— the anterior and posterior lobes. During human fetal development, a third pituitary gland region called the pars intermedia atrophies and disappears. However, some of its cells migrate and exist adjacent to the anterior pituitary in adults.

The Parathyroid Glands00:59

The Parathyroid Glands

4.5K
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...

Summary

Simultaneous pleomorphic adenomas in the parotid and submandibular glands are rare. This case highlights the importance of considering bilateral salivary gland tumors when diagnosing unilateral swellings.

Area of Science:

  • Head and Neck Surgery
  • Oncology
  • Pathology

Background:

  • Pleomorphic adenomas are common benign salivary gland neoplasms.
  • Simultaneous occurrence in homolateral salivary glands is exceptionally rare.

Observation:

  • A case of a female patient with bilateral swellings in the right preauricular and submandibular regions.
  • Diagnosis of pleomorphic adenoma confirmed by fine needle aspiration cytology and histopathology.
  • Surgical excision performed with preserved facial nerve function.

Findings:

  • Histopathology confirmed pleomorphic adenoma in both the parotid and submandibular glands.
  • Literature review identified only nine previously reported cases of simultaneous homolateral salivary gland pleomorphic adenoma.

Implications:

  • This rare presentation underscores the need to consider multifocal salivary gland tumors.
  • Clinicians should maintain a high index of suspicion for simultaneous tumors in homolateral glands when evaluating salivary gland swellings.
