Final answer:
The only benign tumor to cross the epiphyseal plate is a giant cell tumor.
Step-by-step explanation:
The only benign tumor to cross the epiphyseal plate is called a giant cell tumor.
The epiphyseal plate is responsible for the lengthwise growth of long bones. It is located in the region between the diaphysis (shaft of the bone) and the epiphysis (rounded end of the bone).
The giant cell tumor is a rare and typically non-malignant tumor that can occur in the epiphyseal plate and affect bone growth.
