Differential Diagnosis

Sarcoidosis has many differentials, which can be classified depending on the organ involved.[1]

Lung[2]

1.Tuberculosis 2.Atypical Mycobacteriosis 3.Cryptococcosis 4.Aspergillosis 5.Aspiration of foriegn materials 6.Blastomycosis 7.Pneumocystitis carinii 8.Pneumoconiosis 9.Drug reactions 10.Hypersensitivity pneumonitis 11.Drug reactions12..Histoplasmosis 13.Chronic interstitial pneumonia 14.Necrotizing sarcoid granulomatosis 15.Wegner's granulomatosis

Lymph Node

1.Tuberculosis 2.Atypical Mycobacteriosis 3.Brucellosis 4.GLUS syndrome 5.Cat scratch disease 6.Toxoplasmosis 7.Hodgkin disease 8.Non Hodgkin lymphoma 9.Sarcoid reaction in lymph nodes to carcinoma 10.Kikuchi disease(granulomatous histiocytic necrotizing lymphadenitis)

Skin

1.Tuberculosis 2.Atypical mycobacteriosis 3.Fungal infection 4.Rheumatoid nodules 6.Reaction to foreign bodies

Liver

1.Tuberculosis 2.Brucellosis 3.Schitosomiasis 4.Crohn's disease 5.Hodgkin's disease 6. Non hodgkin's lymphoma 7.GLUS syndrome 8.Primary biliary cirrhosis

Bone Marrow

1.Tuberculosis 2.Histoplasmosis 3.Cytomegalovirus 4.Drugs 5.Infectious Mononucleosis 6.GLUS syndrome 7.Hodgkin's disease 8.Non Hodgkin's lymphoma

Other biopsy sites

confirmation

  • CXR and CT demonstrates cavities in the upper lobe of the lung
  • Sputum smear positive for acid-fast bacilli and nucleic acid amplification tests (NAAT) is used on sputum or any sterile fluid for rapid diagnosis and is positive for mycobacteria.
  • Any age group
  • Acute, fulminant life threating complication of prior infection
  • >100.4F fever, with hemodynamic instability
  • Worsening pneumonia-like symptoms
  • CBC is positive for causative organism
  • Children and elderly are at risk
  • Empyema appears lenticular in shape and has a thin wall with smooth luminal margins
  • Pulmonary nodules with cavities and infiltrates are a frequent manifestation on CXR
  • Elderly females of 40-50 age group
  • Manifestation of rheumatoid arthritis
  • Presents with other systemic symptoms including symmetric arthritis of the small joints of the hands and feet with morning stiffness are common manifestations.
  • Pulmonary nodules with cavitation are located in the upper lobe (Caplan syndrome) on Xray.
  • On CXR bilateral adenopathy and coarse reticular opacities are seen.
  • CT of the chest demonstrates extensive hilar and mediastinal adenopathy
  • Additional findings on CT include fibrosis (honeycomb, linear, or associated with bronchial distortion), pleural thickening, and ground-glass opacities.[9]
  • Common appearance on CT is patchy consolidation,often accompanied by ground-glass opacities and nodules.[13]
  • Exclusively afflicts smokers, with a peak age of onset of between 20 and 40 years.
  • Clinical presentation varies, but symptoms generally include months of dry cough, fever, night sweats and weight loss.
  • Skin is involved in 80% of the cases, scaly erythematous rash is typical.
  • Thin-walled cystic cavities are the usual radiographic manifestation, observed in over 50% of patients by either CXR or CT scans.[15]
  • Biopsy of the lung
