Adamantinoma is an uncommon benign bone tumour.
It should not be confused with adenomatoid tumour.
General
Features:[1]
- Rare: < 1% of bone tumours.
- Typically 25-35 years old.
- Benign, may be locally aggressive.
Gross
- Classically mid portion of tibia.[2]
- Fibula common.
- Reported in many other sites.
Radiology
- Intracortical, radiolucent.
Microscopic
Features:
- Biphasic tumour:[2]
- Fibro-osseous component.
- Spindle cells.
- Epithelial component.
- Classically nests of basaloid cells.
- Fibro-osseous component.
Note:
- It is described as resembling ameloblastoma,[2] but the resemblance isn't striking.
DDx:[3]
