Non-neoplastic conditions
In many benign disorders, effusions show a non-specific cytologic picture. However, some conditions are characterized by specific cytologic features which may be helpful in the differential diagnosis.
- Acute serositis
- Eosinophilic effusions
- Tuberculosis pleuritis
- Rheumatoid pleuritis
- Systemic lupus erithematosus (SLE)
Effusions due to pulmonary infarct
- Reactive mesothelial cells (often)
- Mitoses
- Haemosiderinophages
- Eosinophils (up to 60%)
- Lymphocytes and neutrophils
