Study Notes
Tumors with Distinctive Features
-
Tumor with Reactive Bone Formation
- Characterized by a thick rim of reactive cortical bone.
- Contains trabeculae of woven bone, which are rimmed by osteoblasts.
-
Sunburst Effect Tumor
- Exhibits a 'sunburst' pattern.
- Features streaks of new bone radiating outward from the cortex.
-
Painful Mass with Codman's Triangle
- Described as a 'painful enlarging mass.'
- May show Codman's triangle, indicative of reactive new bone formation.
-
Cystic Degeneration Tumor
- Composed of red-brown masses that often undergo cystic degeneration.
- Primarily affects middle-aged and elderly patients.
-
Tumor with Osteoclasts
- Contains a high number of osteoclasts.
- Almost exclusively affects adults, particularly in the pelvis and shoulder regions.
