As will be pointed out later in the discussion, this type of neoplasm may have either a slow or a relatively fast rate of growth, depending on the phase of bone development in which it appears. Then, again, though histologically benign, this tumor may become clinically malignant by virtue of being located in the proximity of many important structures.
