    Insights

    This study analyzed 66 cutaneous tuberculosis cases, finding lupus vulgaris most common, particularly in unvaccinated children. Skin lesions frequently appeared on the face, with systemic involvement noted in over a quarter of patients.

    Area of Science:

    • Dermatology
    • Infectious Diseases
    • Microbiology

    Background:

    • Cutaneous tuberculosis (TB) presents diverse clinical manifestations.
    • Understanding epidemiological patterns is crucial for early diagnosis and management.

    Purpose of the Study:

    • To analyze the clinical characteristics and epidemiological features of cutaneous tuberculosis.
    • To identify common disease patterns, affected demographics, and associated systemic involvement.

    Main Methods:

    • Retrospective analysis of 66 patients diagnosed with cutaneous TB over four years.
    • Data collection included patient demographics, clinical presentation, histopathology, and Mantoux test results.

    Main Results:

    • Males predominated (71.6%). Lupus vulgaris (81.8%) was the most frequent type, followed by scrofuloderma (21.2%).
    • Facial involvement was most common (34.8%). Systemic involvement occurred in 25.8%, primarily pulmonary.
    • Histopathology confirmed TB in 81.8%; Mantoux test was negative in 27.2%.

    Conclusions:

    • Cutaneous TB predominantly affects males and children, with lupus vulgaris being the most common form.
    • Facial lesions and pulmonary involvement are significant features.
    • Diagnostic challenges exist, as indicated by negative Mantoux tests and non-specific histopathology in some cases.

    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:

    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 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 V

    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...

    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...

    Skin Diseases and Disorders

    Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
    Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
