Giant cell reparative granuloma
and brown tumor of hyperparathyroidism contain areas of aggregated giant cells that have less nuclei-per-cell than those in the GCT and have a more fibrotic stroma with more prominent hemorrhage and hemosiderin deposition than the GCT.
19) The so-called solid variant of ABC, (20) is nothing more than a giant cell reparative granuloma
Peripheral giant cell granuloma (PGCG) is an infrequent exophytic lesion of the oral cavity, also known as giant cell epulis, osteoclastoma, giant cell reparative granuloma
, or giant-cell hyperplasia.
Differential diagnosis includes giant cell reparative granuloma
, cherubism, true giant cell tumor, aneurismal bone cyst, and solitary bone cyst (61.

DISCUSSION: Peripheral giant cell granuloma (PGCG) was first reported as fungus flesh in 1848,  then reported as giant cell reparative granuloma
by Jaffe in 1953.
Tumour like conditions included subchondral cyst, aneurysmal bone cyst, giant cell reparative granuloma
, myositis ossificans, fibrous dysplasia and metaphyseal fibrous defect.
It is also known as giant cell epulis, (1) giant cell reparative granuloma
, osteoclastoma, or giant cell hyperplasia.
Aneurysmal bone cyst, chondroblastoma, dermoid cyst, chondrosarcoma, giant cell reparative granuloma
, and pigmented villonodular synovitis are the most important entities that should be included in the radiologic differential diagnosis.
