Summary
Tuberculous pseudotumour, a rare lung tuberculosis form, mimics cancer in immunocompetent individuals. Diagnosis is challenging due to non-specific symptoms and often negative sputum tests, leading to delays.
Area of Science:
- Pulmonology
- Infectious Diseases
- Oncology
Context:
- Bronchopulmonary tuberculosis can present atypically as a pseudotumour.
- This presentation is rare, particularly in immunocompetent patients.
- Tuberculous pseudotumours can be misdiagnosed as lung cancer.
Purpose:
- To determine the frequency and clinical characteristics of tuberculous pseudotumours in immunocompetent patients.
- To analyze diagnostic challenges associated with this rare presentation.
Summary:
- Over 11 years, 12 cases (3.5%) of tuberculous pseudotumour were identified among 341 pulmonary tuberculosis patients.
- Patients were middle-aged smokers presenting with non-specific symptoms like cough and chest pain.
- Radiological and bronchoscopic findings often mimicked lung cancer, with a mean diagnostic delay of 47 days. Diagnosis confirmation relied heavily on histology due to low bacteriologic yield.
Impact:
- Highlights the diagnostic difficulty of tuberculous pseudotumour mimicking lung cancer.
- Emphasizes the need for increased clinical suspicion for tuberculosis in cases presenting as lung masses, especially with negative sputum smears.
- Underscores the importance of histological confirmation for accurate diagnosis and timely treatment.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

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:

01:28Pulmonary 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...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
