Giant cell tumour of bone
Diagnosis in short

Giant cell tumour of bone. H&E stain.
LM giant cells (usu. with >10 in the plane of section), mononuclear cells and small multinucleated cells with nuclei similar to those in the giant cells
LM DDx other giant cell lesions
IHC p63 +ve (patchy)
Site bone, epiphysis usually
Clinical history usu. young adults (20-45 years old)
Signs +/-immobility
Symptoms +/-pain
Prevalence uncommon ~ 5% of primary bone tumours

Giant cell tumour of bone is an uncommon bone tumour.

General

Features:[1]

  • Approximately 5% of primary bone tumours.
  • Typical age: 20-45 years.

Clinical

  • Location: growth plate of long bones.[2]
    • May present with joint pain, immobility.

Note:

Microscopic

Features:[3]

  • Giant cells with a large number of nuclei (usu. >10 in the plane of section).
  • Mononuclear cells and small multinucleated cells with nuclei similar to those in the giant cells - key feature.
  • +/-Hemosiderin deposition - not common.[4][5]

Notes:

  • Giant cells typically present in abundance.

DDx:

Images

  • GCT of bone - low mag. (WC)

  • GCT of bone - intermed. mag. (WC)

  • GCT of bone - high mag. (WC)

  • GCT of bone - very high mag. (WC)

IHC

  • p63 +ve in scattered mononuclear cells.[6]
    • This seems to be contradicted by another paper.[7]
