Giant cell tumor is most frequently located in which bone region?

Explanation:
Giant cell tumors originate in the epiphysis of long bones, right next to the joint surface. This location explains their growth pattern: the tumor expands within the epiphysis and can extend into the adjacent metaphysis, and if it advances far enough it may cross the joint space by breaching the articular surface. Because of this, the most accurate description is that it is epiphyseal and may cross the joint.
