Central giant cell reparative granuloma
is an infrequent, benign, proliferating lesion affecting the maxilla, mandible and, rarely, cranial bones.
Differential diagnosis for lesions that centered within the thyroid or crycoid cartilage includes giant cell reparative granuloma
, brown tumor of hyperparathyroidism, osteoblastoma, chondroblastoma, chondrosarcoma, chondroma, aneurysmal bone cyst, nonossifying fibroma, foreign body reaction, benign fibrous histiocytoma, malignant fibrous histiocytoma, osteosarcoma with abundant giant cells, and carcinoma (including spindle cell or sarcomatoid carcinoma) with giant cells.
19) The so-called solid variant of ABC, (20) is nothing more than a giant cell reparative granuloma
Solid variant of aneurysmal bone cysts in long tubular bones: giant cell reparative granuloma
Differential diagnosis includes giant cell reparative granuloma
, cherubism, true giant cell tumor, aneurismal bone cyst, and solitary bone cyst (61.
and brown tumor of hyperparathyroidism must be included in the differential diagnosis.
These include aneurysmal bone cyst, chondroblastoma, nonossifying fibroma, giant cell reparative granuloma
, pigmented villonodular synovitis, giant cell tumor of tendon sheath, and giant cell-rich osteosarcoma.
The differential diagnosis includes an eurysmal bone cysts, chondroblastoma, chondromyxoid fibroma, giant cell reparative granuloma
, nonossifying fibroma, Langerhans' cell histiocytosis, synovial sarcoma, and high-grade central osteosarcoma.
That situation likely applies to nodular fasciitis, (86-88) proliferative myositis, (88,89) giant cell reparative granuloma
of bone (80,90,91) (Figure 4, A through D), fibrohyaline pleuritis (92,93) (Figure 5, A and B), and xanthogranulomatous inflammation in several sites.
A clinical diagnosis of reparative granuloma
was made, and tympanotomy and revision stapedectomy were performed.
A reparative granuloma
can be differentiated from a brown tumor by the absence of hyperparathyroidism.
The differential diagnosis for this cytomorphologically benign lesion included villonodular synovitis, giant cell reparative granuloma
, and benign chondroblastoma.
