A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. [1] [3] It is considered to be benign since it does not spread beyond the bone. [4] Unicameral bone cysts can be classified into two categories: active and latent. [4]
Some unicameral bone cysts may spontaneously resolve without medical intervention. Specific treatments are determined based on the size of the cyst, the strength of the bone, medical history, extent of the disease, activity level, symptoms an individual is experiencing, and tolerance for specific medications, procedures, or therapies.

Simple bone cyst (also termed unicameral bone cysts): A subset of these tumors contain neoplastic cells that express the FUS-NFATC2 or EWSR1-NFATC2 fusion gene. [1] A recent study reported that the neoplastic cells in these cysts expressed a FUS-NFATC2 fusion gene in four and the EWSR1-NFATC2 fusion gene in two of nine test cases.
The lesion may arise de novo or may arise secondarily within a pre-existing bone tumor, because the abnormal bone causes changes in hemodynamics. An aneurysmal bone cyst can arise from a pre-existing chondroblastoma, a chondromyxoid fibroma, an osteoblastoma, a giant cell tumor, or fibrous dysplasia. A giant cell tumor is the most common cause ...
Cysts of the jaws are cysts—pathological epithelial-lined cavities filled with fluid or soft material—occurring on the bones of the jaws, the mandible and maxilla.Those are the bones with the highest prevalence of cysts in the human body, due to the abundant amount of epithelial remnants that can be left in the bones of the jaws.
A number of tumors have giant cells, but are not true benign giant-cell tumors. These include aneurysmal bone cyst, chondroblastoma, simple bone cyst, osteoid osteoma, osteoblastoma, osteosarcoma, giant-cell reparative granuloma, Giant-cell tumor of the tendon sheath and brown tumor of hyperparathyroidism.

A non-ossifying fibroma (NOF) is a benign bone tumor of the osteoclastic, giant cell-rich tumor type. [1] It generally occurs in the metaphysis of long bones in children and adolescents. [2] Typically, there are no symptoms unless there is a fracture. [2]
