Ewing tumour - X-ray appearance right femur
knee
Periosteal lamellation (circular)
Diaphyseal tumour
Massive swelling of soft tissue

Ewing tumour - MR appearance right femur
  • Intraossous extension
  • Soft tissue extension
  • Topography
  • Skip lesions?

Ewing tumours - Histology
  • small blue round cell
  • some mitoses
  • malignant cell population
  • infiltrating growth
  • PAS positive (glycogen)
  • CD99/Mic2 positive
  • -/ neuronal differentiation (ES -gt atyp. ES -gt
