The Bronchial Tree01:23

The Bronchial Tree

7.5K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

834
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

5.0K
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Anatomy of Respiratory System II: Lower Respiratory Tract

4.7K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Other Pulmonary Disorders01:17

Other Pulmonary Disorders

1.8K
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Area of Science:

  • Pulmonology
  • Surgical Pathology
  • Oncology

Background:

  • Pleomorphic adenomas are the most common salivary gland tumors.
  • These benign neoplasms uncommonly manifest in the respiratory system, affecting central airways and lung parenchyma.
  • Endobronchial manifestations are exceedingly rare, posing diagnostic challenges.

Purpose of the Study:

  • To report a rare case of endobronchial pleomorphic adenoma.
  • To describe the diagnostic and therapeutic approach for this unusual lung tumor.
  • To contribute to the literature on extraglandular pleomorphic adenomas.

Main Methods:

  • A 60-year-old male smoker with an incidental lung nodule underwent evaluation.
  • Bronchoscopy revealed a smooth, globular endobronchial mass at the main carina.
  • The mass was successfully resected using an electrocautery snare.

Main Results:

  • Histopathological examination confirmed the endobronchial mass to be a pleomorphic adenoma.
  • The lesion was benign, with no evidence of malignancy.
  • Complete resection was achieved.

Conclusions:

  • Pleomorphic adenoma is a rare but possible cause of endobronchial tumors.
  • Bronchoscopic evaluation and resection are effective for diagnosis and treatment.
  • This case underscores the importance of considering extraglandular pleomorphic adenomas in the differential diagnosis of endobronchial lesions.
