ependymomas accounts for about 2%–6% of cns and 60%–70% of spinal cord tumors. several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. in spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. this report presents a case of giant cell ependymoma...

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...

abstract background: cholesterol cleft granulomas with clusters of giant cells were noted to be a common feature of non-specific interstitial pneumonia (nsip). objective: this study aimed to define the cell populations involved in the granulomas. methods: the granulomas of 16 patients with cryptogenic fibrosing alveolitis (five cases with the histological features ofnsip, five with those ofuip ...

  Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal ...

BACKGROUND: In the present study, the submandibularsalivary gland microscopic morphology of the adult Africangiant pouched rat was investigated. This study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. This becomes of evenhigher importance when considering th...
