Summary
Tuberculosis cutis orificialis, a rare oral tuberculosis form, can affect the gums. Early dental identification of Mycobacterium tuberculosis aids in controlling this infectious disease.
Area of Science:
- Oral Medicine
- Infectious Diseases
- Dermatology
Background:
- Tuberculosis cutis orificialis is a rare form of cutaneous tuberculosis affecting mucosal surfaces.
- The oral cavity, particularly the tongue, is the most common site for orificial lesions.
Observation:
- A case of tuberculosis cutis orificialis involving the gingiva in a 35-year-old female is presented.
- The patient had a six-month history of a painful gingival ulceration.
- Histopathology revealed granulomatous inflammation with caseating necrosis.
Findings:
- Purified protein derivative test and sputum culture were positive for Mycobacterium tuberculosis.
- Imaging confirmed active pulmonary tuberculosis.
- Polymerase chain reaction on the gingival specimen also detected Mycobacterium tuberculosis.
Implications:
- Gingival involvement of tuberculosis cutis orificialis is rare but significant.
- Dental identification of Mycobacterium tuberculosis can be crucial for early diagnosis and control.
- Prompt anti-tuberculosis therapy leads to complete resolution.

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, 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, 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.

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...

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...
