low power view of monostotic fibrous dysplasia of bone

low power view of monostotic fibrous dysplasia of bone •A low power view of a focus of fibrous dysplasia of bone. •At this power, one can appreciate that this tumor consists of two areas. •The majority of this field is seen to be composed of a highly cellular tissue. •The green arrows point to foci within this tumor, which seem to be relatively less cellular and more evenly eosinophilic staining. •These eosinophilic areas represent new bone formation and osteoid deposition within the tumor.
