OSTEOFIBROUS DYSPLASIA LIKE-ADAMANTINOMA Figure 10-11 OSTEOFIBROUS DYSPLASIA LIKE-ADAMANTINOMA Left: Based on current criteria, the distinction of osteofibrous dysplasia from osteofibrous dysplasia-like adamantinoma is the presence of epithelial nests (clusters of three or more cells). Right More about this image found in OSTEOFIBROUS DYSPLASIA LIKE-ADAMANTINOMA Left: Based on current criteria, ...

OSTEOFIBROUS DYSPLASIA Figure 10-6 OSTEOFIBROUS DYSPLASIA The keratin-positive cells in osteofibrous dysplasia are solitary and spindled. When keratin-positive cells are more round and form small clusters, a diagnosis of osteofibrous dysplasia-like adamantinoma is warranted.

OSTEOFIBROUS DYSPLASIA Figure 10-3 OSTEOFIBROUS DYSPLASIA Resection specimen of osteofibrous dysplasia of the tibia, showing the cortical thickening. Solid white-yellow tissue is seen with a soft or gritty texture, blending into the surrounding cortical bone.

OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Figure 10-10 OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Left: Osteoclast-like giant cells in osteofibrous dysplasia-like adamantinoma are close to the woven bone trabeculae. Right: High-power view shows small nests of epithelial cells. More about this image found in OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Left: Osteoclast-like giant cells...

OSTEOFIBROUS DYSPLASIA Figure 10-2 OSTEOFIBROUS DYSPLASIA A: Lateral radiograph of the leg shows a lytic lesion in the anterior cortex of the distal tibial shaft (arrows), the typical location of osteofibrous dysplasia. B: Magnified view shows multiple lytic cortical lesions. C: Axial More about this image found in OSTEOFIBROUS DYSPLASIA A: Lateral radiograph of the leg shows a lytic lesi...

OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Figure 10-9 OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Left: At low power morphology is very similar to that of osteofibrous dysplasia, with irregular woven bone lined by well-defined osteoblasts in a background of fibrous stroma. Distinction should be made More about this image found in OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Left: At low power morphology is ...

OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Figure 10-7 OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA A: Lateral radiograph of the leg in a patient with osteofibrous dysplasia-like adamantinoma shows a lytic lesion in the anterior tibia, which involves the anterior cortex with extension More about this image found in OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA A: Lateral radiograph of the leg ...

OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA Figure 10-8 OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA The cortex and medullary cavity are involved by tumor. More about this image found in OSTEOFIBROUS DYSPLASIA-LIKE ADAMANTINOMA The cortex and medullary cavity a...

OSTEOFIBROUS DYSPLASIA Figure 10-5 OSTEOFIBROUS DYSPLASIA Prominent osteoblastic rimming of irregular woven bone trabeculae is characteristically seen in a background of a bland, storiform, fibrous spindle cell proliferation.

OSTEOFIBROUS DYSPLASIA Figure 10-1 OSTEOFIBROUS DYSPLASIA A: Lateral radiograph of the leg in a 2-year-old girl demonstrates a well-defined cortical lytic lesion with sclerotic margins in the anterior tibial diaphysis. B: Sagittal fat-suppressed T2-weighted magnetic resonance imaging (MRI More about this image found in OSTEOFIBROUS DYSPLASIA A: Lateral radiograph of the leg in a 2-year-old gi...

OSTEOFIBROUS DYSPLASIA Figure 10-4 OSTEOFIBROUS DYSPLASIA Left: Woven bone is being formed in an irregular fashion by well-defined osteoblasts. There is a loose fibrous stroma in which the fibrous cells have bland, ovoid to thin and pointed nuclei. Their cytoplasm is pale eosinophilic with ill More about this image found in OSTEOFIBROUS DYSPLASIA Left: Woven bone is being formed in an irregular fa...
