Sarcoidosis is a rare condition that can cause prolonged fever and swollen lymph nodes. Early diagnosis and corticosteroid treatment led to complete symptom recovery in a young patient.

Area of Science:

  • Internal Medicine
  • Pulmonology
  • Rheumatology

Background:

  • Sarcoidosis diagnosis can be challenging, particularly in cases presenting with prolonged fever of unknown origin.
  • Malignant hematologic disorders are often considered in the differential diagnosis of unexplained systemic symptoms.

Observation:

  • A 25-year-old patient presented with persistent fever (>3 months), night sweats, fatigue, and significant weight loss.
  • Physical examination revealed splenomegaly and widespread lymphadenopathy (cervical, thoracic, abdominal).

Findings:

  • Bone marrow and lymph node biopsies showed epithelioid noncaseating granulomas.
  • Elevated serum angiotensin-converting enzyme (ACE) and lymphocytic alveolitis were detected.
  • These findings confirmed a diagnosis of sarcoidosis, excluding hematologic malignancy.

Implications:

  • Sarcoidosis should be considered in the differential diagnosis of fever of unknown origin, even without chest X-ray abnormalities.
  • Corticosteroid therapy effectively resolved all symptoms, including organomegaly and lymphadenopathy.
  • This case highlights the importance of a comprehensive diagnostic approach for systemic inflammatory diseases.
