Where does Multilobular Tumor of Bone most typically originate?

Explanation:
Multilobular tumor of bone is a slow-growing bone tumor that most characteristically arises from the skull bones in dogs. The flat bones of the calvaria provide the usual origin site, which is a classic feature of this tumor. Because it starts in skull bones, it often presents as a firm, lobulated mass on the head and can expand within cranial structures, whereas tumors in long bones, the vertebral column, or the pelvis are much less typical for this entity. While MBT can be locally aggressive, metastasis is relatively uncommon, and the skull origin helps explain both its presentation and its preferred location.
