Osteoblastoma: A 30‐year study of 99 cases

Abstract: Osteoblastoma frequently affects the long bones and the spine. The recurrence rate following curettage is relatively high and can be minimized by resective surgery, in select cases.

“…Aggressive osteoblastoma tends to extend into tissue adjacent to the tumor and recurs but does not metastasize (1). It is challenging to distinguish between aggressive osteoblastoma and low-grade osteosarcoma because of the similar histological characteristics of their invasive structures (9).…”

“…Definitive diagnosis of osteoblastoma is not possible by radiography (1), but computed tomography (CT) or magnetic resonance imaging (MRI) can still be used to distinguish between osteoblastoma and osteosarcoma (1,5). CT and MRI can help diagnosis by estimating the size of tumor and its relationship with adjacent tissue.…”

“…3 Unlike osteoid osteoma, the pain of osteoblastoma usually does not respond to NSAIDs and is not generally more severe at night. 5 Radiographic features of osteoblastoma are variable, usually showing a combination of radiolucent and radiopaque patterns, depending on the degree of lesional calcification, but without a sclerotic border or periosteal reactions. 2 An osteoid osteoma should demonstrate a radiographic nidus of Ͻ1 cm, whereas an osteoblastoma should measure Ͼ2 cm in greatest dimension.…”

“…5 It is a bone-forming tumor characterized by osteoid and woven bone deposition and abundant osteoblasts that are frequently in close association with newly formed bone. Occasionally, osteoblastomas may appear richly cellular, contain an abundant osteoclast-like component, and show plump osteoblasts that may evoke a diagnosis of osteosarcoma, thus leading to unnecessary overtreatment.…”

“…4,7,9 Rib lesions are also uncommon and constitute only 5% of osteoblastomas. 2,12,19 Optimal management of these cases is uncertain, as this is typically a benign lesion. Resection is usually performed because of pain or neurological sequelae, neither of which was present in our patient.…”
