EBUS-TBNA and CryoEBUS of the mediastinal lymph node. One hundred seventy-eight cases. Validation of the WHO Reporting System for Lymphin Node Cytopathology. Proposed CryoEBUS diagnostic flow chart and indications. The view of the interventional pathologist

Microscopic assessment is essential in the study of mediastinal lymph nodes. Obtaining cytological samples through Endobronchial Ultrasound TransBronchial Needle Aspiration (EBUS-TBNA) has long been considered the gold standard procedure. The implementation of the World Health Organization (WHO) Reporting System for Lymph Node Cytopathology, along with the advancement of the CryoEBUS lymph node technique, has enhanced and refined diagnostic accuracy in this field.
