Summary
Bronchial anthracofibrosis, characterized by airway narrowing and dark pigmentation, can mimic other conditions in non-smokers. This case highlights the importance of considering this diagnosis and suggests cautious monitoring before invasive procedures.
Area of Science:
- Pulmonology
- Medical Case Reports
Background:
- Bronchial anthracofibrosis is defined as airway narrowing with dark pigmentation on bronchoscopy.
- It is diagnosed in the absence of a history of pneumoconiosis or smoking.
Observation:
- A 67-year-old non-smoking female presented with a two-year history of persistent cough.
- Spirometry results were normal.
- Radiological imaging revealed right middle lobe atelectasis and positron emission tomography-positive mediastinal lymph nodes.
- Bronchoscopy showed black airway discoloration and distortions.
Findings:
- The patient's presentation and bronchoscopic findings were consistent with bronchial anthracofibrosis.
- The absence of smoking or pneumoconiosis history complicated the diagnosis.
Implications:
- This case underscores the importance of considering bronchial anthracofibrosis in non-smokers presenting with relevant symptoms.
- The authors propose monthly radiological monitoring for suspected cases lacking strong indicators of malignancy or tuberculosis, prior to invasive interventions.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

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...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

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.

01:17Gross Anatomy of the Lungs
3.0K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...
