Pt’s younger than 30 yoa, what tumors are located in epiphysis?
Chondroblastoma
Infection

Periosteal reaction may be classified as benign or aggressive. True or False
True
Benign low-grade chronic irritation permits formation of normal/near-normal cortex. It’s seen in callus formation in fracture or slow growing tumors. True or False
True
note: cortex will be thick, dense, wavy or uniform in appearance
In an aggressive periosteal reaction what will the cortex look like?
lamellate, amorphous or Sunburst-like
Aggressive periosteal reaction are seen in Malignant and Benign tumors. Name 3 benign processes this reaction can be seen.
ABC Osteoid osteoma Infection Eosinophilic granuloma Hemophilia Trauma
