A sessile bony mass arising from the proximal metaphyso-diaphyseal region of the right humerus, displacing the overlying soft tissues. The medullary cavity, as well as the cortex, are in continuity with those of the parent bone with thinning of the cortex. No fracture or periosteal reaction is seen.
