Insights

Disseminated cutaneous tuberculosis is rare in immunocompetent children, even after Bacillus Calmette-Guérin (BCG) vaccination. This case highlights a rare presentation of BCG-site tuberculosis in an infant, successfully treated with standard therapy.

Area of Science:

  • Pediatrics
  • Dermatology
  • Infectious Diseases

Background:

  • Disseminated cutaneous tuberculosis is an uncommon manifestation of tuberculosis.
  • Bacillus Calmette-Guérin (BCG) vaccination is a common procedure worldwide.
  • Cutaneous tuberculosis following BCG vaccination is rare, particularly in immunocompetent individuals.

Purpose of the Study:

  • To report a rare case of disseminated cutaneous tuberculosis in an immunocompetent infant.
  • To highlight the clinical presentation and diagnostic challenges of post-BCG cutaneous tuberculosis.
  • To emphasize the importance of considering tuberculosis in infants with unusual skin lesions.

Main Methods:

  • A clinical case presentation of a 4-month-old girl.
  • Diagnostic confirmation through skin biopsy and histopathological examination.
  • Treatment with standard antituberculosis therapy.

Main Results:

  • The patient presented with widespread scaly papules and a nodule at the BCG immunization site.
  • Biopsy confirmed disseminated cutaneous tuberculosis in an immunocompetent child.
  • Antituberculosis therapy led to complete resolution without recurrence.

Conclusions:

  • Disseminated cutaneous tuberculosis can occur in immunocompetent infants following BCG vaccination.
  • Early diagnosis and appropriate antituberculosis treatment are crucial for favorable outcomes.
  • This case underscores the need for vigilance in diagnosing rare presentations of infectious diseases in pediatric populations.

Pulmonary Tuberculosis IV

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...

Pulmonary 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...

Pulmonary Tuberculosis I

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.

Pulmonary 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:

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...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...
