Abstract
Parosteal Osteosarcoma (POS) is a well-differentiated low-grade malignant sarcoma occurring at the bone surface. POS of the skull is exceedingly rare, with only 4 temporal bone cases reported in modern literature. This tumor may resemble a multitude of entities, hence identifying it is critical. This may be achieved through a combination of clinical, histopathological, and imaging diagnostic techniques. POS may recur locally or dedifferentiate, the latter having a worse prognosis. This review aims to update the reader regarding the management of the rare Parosteal Osteosarcoma located in the skull bone.
