Summary
Sarcoidosis is a multisystem inflammatory disease often diagnosed incidentally. Diagnosis requires histopathological confirmation of noncaseating granulomas, differentiating it from other conditions like tuberculosis.
Area of Science:
- Pulmonary Medicine
- Immunology
- Genetics
Background:
- Sarcoidosis is a multisystem disease with insidious onset.
- It commonly affects Black individuals, typically adolescents and young adults.
- Pulmonary involvement is frequent, presenting with cough, dyspnea, and chest pain.
Purpose of the Study:
- To review the diagnostic approaches to sarcoidosis.
- To highlight key clinical and radiological findings.
- To discuss the importance of histopathological confirmation and differential diagnosis.
Main Methods:
- Review of clinical presentations, diagnostic imaging, and laboratory findings.
- Emphasis on histopathological confirmation via biopsy.
- Discussion of differential diagnoses, particularly tuberculosis.
Main Results:
- Bilateral hilar adenopathy is a classic chest radiograph finding.
- Extrapulmonary manifestations include skin, joint, and eye involvement.
- Laboratory findings may include anemia, elevated liver enzymes, and EKG abnormalities.
Conclusions:
- Histopathological confirmation of noncaseating granulomas is essential for sarcoidosis diagnosis.
- Differential diagnosis, especially tuberculosis, is critical due to overlapping symptoms.
- Emerging techniques like proteomics and gene signatures may offer future diagnostic potential.

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:

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
