Giant cell tumors are distinctive neoplasms characterized by a profusion of multinucleate giant cells scattered throughout a stroma of mononuclear cells. Most giant cell tumors are found at the epiphyses of long bones, especially around the knee joint. Flat bone involvement is rare. However, a case of giant cell tumor with secondary aneurysmal bone cyst was encountered at the scapula of a 25-ye...

BACKGROUND Giant cell tumor is a benign but locally aggressive bone neoplasm which uncommonly involves the skull. The petrous portion of the temporal bone forms a rare location for this tumor. CASE PRESENTATION The authors report a case of a large giant cell tumor involving the petrous and squamous portions of the temporal bone in a 26 year old male patient. He presented with right side sever...

The giant cell tumor of the salivary gland is very rare, and 20 cases have been reported in the English-language literature. We report an additional case. A 57-year old man had noticed a mass in the right parotid area for several weeks. The diagnosis using aspiration cytology was a giant cell tumor possibly with a carcinomatous component. Superficial parotidectomy was carried out. The resected ...

INTRODUCTION Giant cell tumor of the tendon sheath is most commonly found in the flexor aspect of hand and wrist and is rare in the foot and ankle. CASE REPORT A 49-year-old lady noticed a right lateral foot mass for 10 years. Magnetic resonance imaging suggested that the mass is originated from the peroneal tendons. The mass was excised and intra-operative findings showed that the tumor came...

introduction: central giant cell granuloma is a benign lesion but sometimes has aggressive proliferation composed of multinucleated giant cells in a background of spindle and ovoid mesenchymal cells. multifocal central giant cell granuloma of jaws is very rare and usually associated with hyperparathyroidism and some syndromes. we described an un-usual case of a 22-year-old man with idi-opathic ...

central giant cell granuloma is a benign, aggressive neoplasm composed of multinucleated giant cells that almost exclusively occurs in the jaws though extra-gnathic incidence is rare.multifocal cgcgs of the jaws are very rare and suggestive of systemic diseases such as hyperparathyroidism,an inherited syndrome such as noonan-like multiple giant cell lesion syndrome or other disorders.very few c...

two new cases of aneurysmal bone cyst of the spine are presented. in one of them only the spinous process was involved, and in the second case mthe neural arch and the body were involved. a brief review of the literature with clinical, radiological and pathilogical features of this benign lesion is made and its differential diagnosis, specially from giant cell tumor of the spine emphasised.

BACKGROUND Typical aneurysmal bone cysts (ABCs) are osteolytic, multicystic lesions with parietal sclerosis and blood-filled cysts. In rare instances, the cystic components may be completely absent. Such solid variants in ABC (s-ABC) exhibit a solid architecture; making the clinical, radiological, and histological differentiation from other solid bone tumors like osteosarcoma (especially giant ...

Giant cell tumor is a benign locally aggressive tumor. The standard treatment is en bloc resection followed by major reconstructive surgery, or extended curettage conjunction with bone grafting or the use of bone cement implantations. Surgical treatment of giant cell tumor at the sacrum is associated with high morbidity, and local recurrence. The authors present a case of giant cell tumor at th...
