Summary
Pulmonary capillariasis, a rare zoonotic lung infection, was diagnosed in a Serbian woman. This case highlights the worm Capillaria aerophila mimicking bronchial carcinoma in humans.
Area of Science:
- Veterinary Medicine
- Human Medicine
- Parasitology
Background:
- Pulmonary capillariasis is a rare zoonotic disease caused by the nematode Capillaria aerophila.
- This parasite typically circulates among wild carnivorous and omnivorous mammals.
- Human infections are exceptionally rare, with only 11 cases documented globally.
Observation:
- A Serbian woman presented with symptoms suggestive of a serious respiratory condition.
- Diagnostic imaging revealed findings that mimicked bronchial carcinoma.
- The patient's clinical presentation was unusual and challenging to diagnose.
Findings:
- A cryptic case of pulmonary capillariasis was identified in the patient.
- The nematode Capillaria aerophila was confirmed as the causative agent.
- This diagnosis was made despite the rarity of human infections and the misleading initial presentation.
Implications:
- This case underscores the importance of considering rare zoonotic diseases in differential diagnoses.
- Pulmonary capillariasis can present with symptoms mimicking other severe lung pathologies like cancer.
- Increased awareness among clinicians is crucial for accurate diagnosis and treatment of this neglected parasitic infection.

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:19Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations
Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...
01:17Other Pulmonary Disorders
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.
