Summary
This case study highlights isolated axillary lymph node tuberculosis, a rare form of extrapulmonary tuberculosis. Early diagnosis through imaging and histopathology is crucial for managing this condition.
Area of Science:
- Infectious Diseases
- Radiology
- Pathology
Background:
- Extrapulmonary tuberculosis (TB) is increasing, with lymph node TB being the second most common form.
- Lymph node TB often affects superficial nodes and presents with characteristic ultrasound findings.
Observation:
- A 66-year-old presented with a painless left armpit mass.
- Ultrasound revealed a solid structure with irregular outlines and adjacent hypoechogenic lymph nodes.
- Histopathology confirmed tuberculosis as the cause of the axillary mass.
Findings:
- The patient's presentation mimicked other conditions, including neoplastic metastases.
- Ultrasound showed enlarged, hypoechogenic lymph nodes with blurred outlines and central hyperechogenicity, suggestive of caseation necrosis.
- Histopathological examination was definitive for tuberculosis.
Implications:
- Isolated axillary lymph node TB is a rare but important differential diagnosis for armpit masses.
- Characteristic ultrasound findings can suggest TB lymphadenitis, aiding in early diagnosis.
- Prompt diagnosis and treatment are essential for managing extrapulmonary TB and preventing complications.

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...

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:

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...

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...
