It is also classified as: intraosseous which occurs inside the bone and extraosseous
which presents in the soft tissue over the tooth-bearing areas of the jaws.
blood supply of the tibia and the effects of different plating techniques: a human cadaveric study.
Primary vulvar and vaginal extraosseous
ewing's sarcoma/peripheral neuroectodermal tumor: Diagnostic confirmation with CD99 immunostaining and reverse transcriptase-polymerase chain reaction.
Histologically, HO is the formation of mature lamellar bone in extraosseous
soft tissues (8).
Based on another subclassification, the tumor is considered to be of a unicystic, extraosseous
, peripheral type.
Appropriate understanding of extraosseous
vascular supply of bones along with careful planning before surgeries is important for successful outcome.
(3) Although not standard practice, additional imaging can include PET/CT or whole-body MRI, both of which are excellent in identifying contiguous spread of disease from osseous structures as well as extraosseous
SPECT-CT for characterization of extraosseous
uptake of 99mTc-methylene diphosphonate on bone scintigraphy.
According to literature, three types of odontomas have been recognized clinically: Intraosseous (central) odontoma, extraosseous
(peripheral) odontoma, and erupted odontoma.
The lack of intra- or extraosseous
remodeling (as observed in the specimens) is consistent with a congenital anomaly, as fibrous unions have relatively more stability and less bone remodeling.
In addition, inhouse MRI (sagittal T1-, T2-weighted spinecho and STIR sequences) was performed in all lesions in order to verify the level of malignant vertebral involvement with or without fracture, and to assess the tumoral bone marrow involvement and extraosseous
tumor extension (34).
It is also called, primitive neuroectodermal tumor, Askin tumor (Ewing sarcoma of the chest wall), extraosseous
Ewing sarcoma (Ewing sarcoma in tissue other than bone).
