Sarcoidosis

Also known as: Besnier-Boeck-Schaumann disease

Sarcoidosis is an inflammatory disease characterized by the formation of tiny clumps of inflammatory cells called granulomas in one or more organs, most commonly the lungs and lymph nodes. The exact cause is unknown, but it is thought to result from an abnormal immune response. Many people have no symptoms and the condition may resolve on its own, while others develop chronic organ damage.

Symptoms

Persistent dry cough
Shortness of breath
Fatigue and malaise
Swollen lymph nodes
Skin rashes or lesions
Joint pain and swelling
Blurred vision or eye pain
Fever
Weight loss

Causes

  • Abnormal immune system response to an unknown trigger
  • Possible environmental exposures such as dust, mold, or chemicals
  • Genetic predisposition
  • Possible infectious agents triggering immune activation

Risk Factors

  • African American or Scandinavian descent
  • Age between 20 and 40 years
  • Female sex
  • Family history of sarcoidosis

Diagnosis

  • Chest X-ray or CT scan to detect granulomas
  • Pulmonary function tests
  • Biopsy of affected tissue
  • Blood tests including ACE levels and calcium
  • Bronchoscopy with bronchoalveolar lavage

Treatment

  • Corticosteroids such as prednisone to reduce inflammation
  • Immunosuppressive medications like methotrexate or azathioprine
  • Anti-malarial drugs such as hydroxychloroquine for skin and joint symptoms
  • TNF-alpha inhibitors for refractory cases
  • Regular monitoring without treatment for mild cases

Prevention

  • No known prevention due to unclear cause
  • Avoiding environmental irritants may reduce flare-ups

When to See a Doctor

  • Persistent unexplained cough or shortness of breath
  • New skin rashes or eye problems
  • Unexplained fatigue, fever, or weight loss
  • Swollen lymph nodes that do not resolve
