1] It is important to note that rapidly expanding osteosarcoma tumors, which are typified by permeative bone destruction, may provoke no visible periosteal reactions.
Both circumscribed lytic lesions and permeative lesions have been reported in the spine with involvement of the vertebral bodies, pedicles, and laminae.
Osteosarcomas, as opposed to bone island, show aggressive growth, with cortical destruction, interrupted periosteal reaction, a soft tissue mass, and permeative growth within the bone marrow.
Based on the initial radiographic evaluation, the case was interpreted as a malignant-appearing, permeative mixed sclerotic and lytic lesion in the left proximal tibia.
This lesion has a permeative appearance with an indistinct ZOT and may or may not have an associated soft tissue component (Figure 15).
11) Important histologic features that distinguish it from osteoblastoma include presence of a compact solid proliferation of neoplastic cells in between the bony trabeculae (unlike the single row of osteoblasts seen in osteoblastoma), permeative growth or infiltration beyond the confines of the tumor into adjacent bone or soft tissue, and high mitotic rate.
Plain radiographs characteristically show a solitary osteolytic lesion with a permeative appearance, indistinct margins, irregular cortical erosion, and minimal to no sclerosis or periosteal reaction.
6 In small bones, giant cell tumors tend to show a permeative growth pattern.
Lower extremity radiography (Figure 1) was performed, revealing a permeative osseous lesion involving the proximal right fibula that showed an aggressive periosteal reaction.
Within the marrow, the lesion is poorly marginated, with a permeative pattern of osteolysis (without a beginning and an end) (Figure 1).
Analysis of an additional 55 cases for features typical of aggressive osteoblastoma, including epithelioid osteoblasts, lacelike osteoid, and a permeative growth pattern, also found no predictive value for any of the histologic features.
The classic radiographic features of ES--namely, lytic permeative destruction, aggressive periosteal reaction, cortical violation, and a soft tissue mass--are also typically present in lesions of the hands.
