Summary
A 55-year-old man with lepromatous leprosy presented with skin lesions and nerve thickening. A positive "deck-chair" sign, characterized by sparing of skin creases, was observed, suggesting leprosy as a potential cause.
Area of Science:
- Dermatology
- Infectious Diseases
Background:
- Leprosy is a chronic infectious disease primarily affecting the skin and peripheral nerves.
- Early diagnosis and treatment are crucial to prevent disability.
Observation:
- A 55-year-old male presented with asymptomatic, extensive skin lesions and symmetric peripheral nerve thickening.
- The patient exhibited a distinct sparing of abdominal creases and axillae, a finding known as the "deck-chair" sign.
Findings:
- Bacteriological and histopathological examinations confirmed lepromatous leprosy.
- The presence of the "deck-chair" sign in this leprosy case is a notable observation.
Implications:
- The "deck-chair" sign, previously associated with other dermatological conditions, may now be indicative of leprosy.
- This finding could aid in the early clinical recognition of leprosy, especially in cases with atypical presentations.

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, 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...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

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.
