2. Definition • An aneurysmal bone cyst is a benign, expansile lesion with blood filled cavities separated by septa of trabecular bone or fibrous tissue containing osteoclast giant cells. • The term aneurysmal is derived from its macroscopic appearance - sponge like tumour containing numerous giant cells. 3 2.Aneurysmal bone cyst • Benign • Blood filled • Expansile tumour like bone lesions • Uncertain etiology 17.

Aneurysmal Bone Cyst. Aneurysmal Bone Cysts are benign, non-neoplastic, reactive bone lesions that most commonly occur in the femur and tibia. The condition typically presents in patients less than 20 years of age with focal pain and swelling. Diagnosis is made with radiographs showing an expansile, eccentric, and lytic lesion with bony septae. Aneurysmal bone cysts consist of blood-filled spaces of variable size that are separated by connective tissue containing trabeculae of bone or osteoid tissue and osteoclast giant cells. They are not lined by endothelium. A fine needle aspiration cytology is usually nondiagnostic, often dominated by fresh blood 7 The patella is an unusual location for primary and metastatic bone tumors to develop. The most frequently encountered primary osteolytic lesions at the patella include giant cell tumors of the bone (GCT), chondroblastoma and aneurysmal bone cysts (ABC). However, the presentation of an ABC originating secondary to a GCT at the patella is rare. The present study describes such a case in a 46.

ABCs commonly involve metaphysis of long bones and are rarely diagnosed in craniofacial bones.

In this article, we present a case of a 12-year.

1. Introduction. Aneurysmal bone cyst (ABC) is a type of osseous lesion characterized by a benign pseudocyst with fibrous connective tissue stroma and large spaces filled with blood and no endothelial lining [].ABCs predominantly affect patients in the second decade of life [], as about 80% of cases occur before age 20 [, , ], mainly between 10 and 20 years of age [], being 13 years the median. Aneurysmal bone cyst Metastatic tumors to the jaws. Variant of soap bubble pattern. Septa radiate from a central body, giving the appearance of a spider. Eg: Ameloblastoma Composed of angular rather than rounded compartments that result from the development of more or less straight septa Aneurysmal bone cysts can be seen secondarily to underlying chondroblastoma 13. Histology. Microscopically they are composed of chondroblasts, chondroid matrix, cartilage with occasional giant multinucleated cells (which may lead to the incorrect diagnosis of giant cell tumor)

Aneurysmal bone cyst. Simple bone cyst. An important aspect associated with the first group of tumors lies in the characteristics of the tumor stroma. The stroma is relatively acellular and fibrous in contrast to other groups where the stroma is ectomesenchymal in nature. Odontogenic fibroma represents a rare and controversial tumor Aneurysmal bone cysts have been observed in every part of the skeleton, although more than 50% of lesions occur in the long bones and vertebral column.

A spinal tumor is an abnormal mass of tissue within or surrounding the spinal cord and/or spinal column.These cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells.
