Abstract
|
|
|
|
An 8-year old girl is presented with osteolytic lesion of the right distal femur and a palpable tender mass in this region. While a conventional aneurysmal bone cyst is an expanding osteolytic lesion consisting of blood-filled spaces of variable size, separated by connective tissue containing bone trabeculae or osteoid tissue and many osteoclastic giant cells, a solid aneurysmal bone cyst is an unusual solid bone lesion with fibroblastic, osteoclastic, osteoblastic, aneurysmal, and fibromyoxid elements. The differential diagnosis includes giant cell tumor and fibroblastic osteosarcoma as well as specific bone reactions (bone fracture, reparative giant cell granuloma in hyperparathyroidism, giant cell reaction of short tubular bones). Solid aneurysmal bone cyst is a tumor-like lesion and probably a special bone reaction to damage; it has a good prognosis. Usually curettage is known to be curative. This patient is also treated with curettage and autogenous bone graft.
