NIEFV-PTC

• Non-invasive E-FVPTC could be managed like "minimally invasive follicular carcinoma" by lobectomy without RAI therapy.
• Ecapsulated or well-circumscribed
• papillary-like nuclear features
• exclusion criteria :
  • true papillae > 1% (> CPTC )
  • psammoma bodies (> CPTC )
  • invasive growth (> IEFV-PTC )
  • tumor necrosis (> PDTC )
  • high-mitotic activité (> 3/10 HPFs) (> PDTC )
  • cell morphological characteristics of other variants (other PTC variants)
