Abstract:
Periosteal osteoblastoma is a rare benign osteoblastic bone tumour located on the cortical bone. We report a case of periosteal osteoblastoma located at the distal femur in a 31-year-old man. Clinical, radiological and histopathologic findings are described and differential diagnosis is discussed. Despite its rarity, periosteal osteoblastoma should be considered as a possible diagnosis together with periostitis ossificans, periosteal chondroma, periosteal osteosarcoma and parosteal osteosarcoma when confronted with a superficial bone lesion.

Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...
