The central giant cell granuloma is a benign tumor seen generally in the mandible, but rarely in other cranial bones. Herein, we present a 51-year-old man with central giant cell granuloma in the right zygomatic bone. Physical and radiologic examinations of the central giant cell granuloma in the zygomatic bone showed that specific and preoperative diagnosis is usually difficult. Therefore, clinicians should consider the possibility that central giant cell granuloma may occur in the zygomatic bone mimicking other more frequently observed lesions.

Giant cell tumor of the small bones of the hands and feet is rare. Giant cell tumors in these locations develop at young age, are more commonly multifocal, and show the higher risk of recurrence than those at the end of the long bone. It should be differentiated from the other lesions of the hands, such as giant cell reparative granuloma, aneurysmal bone cyst and enchondroma. We experienced a case of giant cell tumor in the proximal phalanx of the left hand with swelling and pain. Curettage and bone graft were performed. Histologically large number of giant cells were distributed diffusely in the highly cellular stroma containing sheets of mononuclear cells. Secondary aneurysmal bone cyst and hemorrhage were associated.

Folope et al(1999) reported soft tissue giant cell tumor which was similar to malignant giant cell tumor in clinical, pathologic, and immunohistological aspect but represented low malignancy. We reported a 30-year-old female suffered from pain and palpable mass on the anterolateral aspect of the right knee for one year. Excisional biopsy from the lesion revealed some giant cells and polymorphous cells containing eosinophilic cytoplasm and vacuolated nucleus. Histopathologic findings of the lesion were consistent with soft tissue giant cell tumor of low malignant potential. Hereby, we report a case of soft tissue giant cell tumor of low malignant potential with a review of the literature.

Localized forms of giant cell tumor are known to arise commonly in the synovial membrane of the finger joints. Multinucleated giant cells are its characteristic pathology finding, giant cell tumor shows a low rate of recurrence after complete excision. When occurring at the knee joints, giant cell tumor manifests a wide form of symptoms, from no symptom at all, to intermittent locking. Complete excision is possible by arthroscopy, but if done incompletely, it is reported to recur in 45% of cases. We present here a case of giant cell tumor that has arisen from the anterior portion of the posterior cruciate ligament, excised by arthroscopy and followed by pathologic confirmation.

Two cases of giant cell tumor of bone diagnosed by fine needle aspiration cytology are described. Case 1 was a 28-year-old male who had pain sense for one year at the right distal thigh. His radiologic finding revealed a destructive cortical lesion with soft tissue extension at medial side of epiphysis of the distal femur. Case 2 was a 21-year-old female complaining pain at left distal forearm for eight months and showed a well-demarcated expansile osteolytic lesion with multiseptation, and cortical destruction at epiphysis and metaphysis of the left distal radius on the X-ray. Fine needle aspiration of each lesion was performed. The aspirate of the case 1 revealed moderate cellularity, which was composed of scattered giant cells of osteoclastic type and small round to oval monotonous stromal cells in large areas. Giant cells were evenly distributed in single or small groups and had irregular but abundant cytoplasms with 10 to 20 nuclei in the center. The nuclei showed ovoid shape, fine granular chromatin, and a small but conspicuous nucleolus. Stromal cells were dispersed in isolated pattern or sometimes aggregated in clusters and showed the same nuclei as those of giant cells and scanty cytoplasms. Comparing to case 1, case 2 had a more translucent abundant cytoplasm in the giant cells and more spindled stromal cells. All two cases revealed neither nuclear atypism nor increased abnormal mitoses In both giant and stromal cells, suggesting no evidence of malignancy. Thereafter the lesions were treated with excision and curettage, and histologically confirmed as giant cell tumors of the bone.

A Giant cell tumor of bone has unusual characteristics of pulmonary metastasis as well as local aggressiveness. Clinical courses of pulmonary metastasis of benign giant cell tumor vary including rapid growth, continuously slow growth or spontaneous regression. We report a case of extensive pulmonary metastasis of giant cell tumor of bone, which regressed spontaneouly.

A giant cell tumor of bone is a benign bone tumor, but has very high local recurrence rate and, very rarely metastasizes to the lung or a distant area. We report a case of a 29-year-old male patient presenting with a metastatic giant cell tumor of the soft tissue of the chest wall, who underwent a total resection of the radius for recurrence of the giant cell tumor. The tumor was not related to any bony structure of the thorax. We resected the tumor with a wide surgical margin. No evidence of malignancy was seen in the frozen and permanent pathological report.

Giant cell reparative granuloma (GCRG) is an uncommon benign lesion that is most commonly found in the mandible and maxialla, and is a very rare condition in finger. We report an unusual case of GCRG arising in the index finger of a 21-year-old man. Histology was characteristic of giant cell reparative granuloma.

Giant cell tumor is a benign but locally aggressive tumor with common recurrence. Most cases occur around the knee joint. Giant cell tumor of the foot is rare and very few cases involving the first metatarsal have been reported. Its characteristics and treatment in adult patients remain unclear. This paper reports a case of recurrent giant cell tumor at the first metatarsal that was excised surgically and subsequently reconstructed with non-vascularized fibula graft.

The giant-cell tumor is uncommon. It occurs in the long bones and vertebral localization is much less common, particularly in thoracic spine. We present a case of a 37-year-old man suffering from severe back pain. Affected vertebral bodies were removed by transthoracic approach and the spine was reconstructed with iliac bone autografts and internal fixation device(Kaneda) between T 8 and T 11. Histologoical diagnosis was giant-cell tumor, and pertinent literature was reviewed.
