Abstract:
Osteoblastoma is a rare benign bone tumor. Although the histologic features in most cases are distinctive, there are various permutations that make the diagnosis challenging. It can mimic a variety of other benign bone tumors, but more importantly, distinguishing it from osteoblastoma-like osteosarcoma can be difficult. In this case report, I describe the clinicopathologic findings for a 13-year-old adolescent boy with T7 spinal osteoblastoma and review salient clinical, radiographic, and pathologic features of osteoblastoma, as well as the differential diagnoses.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the periosteum and...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Bone Formation by Intramembranous Ossification
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
