§ overviewOverview

Benign but sometimes locally aggressive intraosseous lesion containing multinucleated giant cells.

§ epidemiologyEpidemiology

Female > male; < 30 years; anterior mandible crossing midline is classical.

§ clinicalClinical Features

  • 01Painless expansile swelling
  • 02May displace teeth or resorb roots

§ differentialDifferential Diagnosis

  • 01Ameloblastoma
  • 02OKC
  • 03Aneurysmal bone cyst
  • 04Brown tumour of hyperparathyroidism (must exclude by serum PTH & calcium)

§ histopathHistopathology

  • 01Multinucleated giant cells in vascular fibrous stroma
  • 02Haemosiderin deposits

§ radiographicRadiographic Features

  • 01Uni- or multilocular radiolucency
  • 02Wispy internal septa; may cross midline

§ treatmentTreatment

  • 01Curettage; intralesional corticosteroids or calcitonin for aggressive lesions
  • 02Resection for recurrent aggressive lesions

§ prognosisPrognosis

Recurrence 15–20% after curettage.

§ pearlsClinical Pearls

  • 01Always check serum calcium & PTH to rule out brown tumour.
