Question

which of the following is a metadiaphyseal, permeative, osteolytic lesion with aggressive periosteal changes and saucerization of the cortex that is found in patients younger than 30 years of age? a) multiple myeloma b) ewing sarcoma c) simple bone cyst d) giant cell tumor

Explanation:

• Multiple myeloma typically affects older adults (over 60) and presents with lytic lesions but not the described metadiaphyseal, aggressive periosteal changes in young patients.
• Ewing sarcoma occurs in patients under 30, is metadiaphyseal, has permeative osteolytic lesions, aggressive periosteal reactions, and can cause saucerization of the cortex, matching all criteria.
• Simple bone cyst is a benign, non-aggressive, well-defined lucent lesion without aggressive periosteal changes.
• Giant cell tumor is usually epiphyseal, affects young adults (20-40) but lacks the permeative pattern and aggressive periosteal changes described.

Answer:

B) Ewing sarcoma
