Low power view of an osteosarcoma

Low power view of an osteosarcoma •A low power view of an osteosarcoma. •Even at this power, the extreme cellularity and pleomorphism of this tumor can be readily appreciated. •It is also obvious that the cells appear to vary enormously in size. •The yellow-orange arrow towards the center of this image points to an area of eosinophilic homogeneous appearance. •This is a fragment of malignant osteoid. •Deposition of osteoid and other matrix components is typical of an osteosarcoma.
