Sarcoidosis is a systemic granulomatous disease affecting multiple organs, commonly the lungs. Diagnosis requires excluding other conditions, with specific syndromes offering definitive identification.
Area of Science:
- Pulmonology
- Immunology
- Systemic Diseases
Background:
- Sarcoidosis is a systemic granulomatous disease affecting over 90% of cases in the lungs and intrathoracic lymph nodes.
- It can also impact cardiac, ocular, hepatic, dermatologic, and central nervous systems.
- Pulmonary sarcoidosis presentation is nonspecific, often detected incidentally on chest x-rays.
Purpose of the Study:
- To review the diagnostic challenges and treatment strategies for sarcoidosis.
- To highlight key diagnostic criteria and syndromes.
- To outline current therapeutic approaches for sarcoidosis.
Main Methods:
- Review of existing literature on sarcoidosis diagnosis and management.
- Discussion of differential diagnoses for lymphadenopathy.
- Identification of diagnostic syndromes: Lofgren syndrome, Heerfordt syndrome, and lupus pernio.
Main Results:
- Sarcoidosis diagnosis requires exclusion of other conditions like tuberculosis and cancer.
- Granulomatous findings on lymph node biopsy support the diagnosis.
- Lofgren syndrome, Heerfordt syndrome, and lupus pernio are diagnostic of sarcoidosis.
Conclusions:
- Most sarcoidosis cases resolve spontaneously.
- Treatment is reserved for progressive pulmonary or extrapulmonary involvement.
- Systemic corticosteroids are first-line, with methotrexate or hydroxychloroquine as second-line options for refractory cases.

Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
