Giant-cell reparative granuloma.The characteristics of giant-cell reparative granulomas are similar to those of giant-cell tumors except that they are usually related to pre-existing trauma. Microscopically, giant-cell reparative granulomas feature a zonal reactive inflammatory pattern in which multinucleated multinucleated characterized by having more than one nucleus per cell. multinucleated giant cell see giant cell. giant cells and hemosiderin-laden macrophages surround areas of hemorrhage, as in the case presented here. Osteoid osteoid /os·te·oid/ (os´te-oid) 1. resembling bone. 2. the organic matrix of bone; young bone that has not undergone calcification. os·te·oid adj. Resembling bone. formation can be seen in reparative granulomas it is usually absent in true giant-cell tumors. Giant-cell reparative granulomas are more often found in the mandible, max illa, and sinonasal cavity, where they can cause local expansion and destruction.

Adj. 1. expansile - (of gases) capable of expansion expandable, expandible, expansible mass in the sinonasal cavity on the right. It was detected on physical examination and on computed tomography (CT) (figure).
