background: the aim of this study was to quantify the number of mast cells in focal reactive hyperplastic lesions of the oral cavity and to compare these two number of mast cells in normal gingival tissues and to correlate their presence with the state of connective tissue changes in reactive lesions and probably suggest a role for mast cells in these lesions. materials and methods: patient rec...

Giant cell tumor of soft parts is a rare tumor that is clinically and histologically similar to giant cell tumor of the bone. We present a 53-year-old female with a giant cell tumor of low malignant potential arising from the neck. The clinicopathological features and the importance of immunohistochemistry in the differential diagnosis with other giant cell rich tumors was discussed.

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 ...

five cases of giant cell tumor of the lower end of radius are reported. three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years. en bloc resection followed by reconstructive procedures were performed in three of the cases with good results.

giant cell granulomas of the jaws are rather common in [rail, however, more reliable data need to be published in this retrospecti ve study 1,083 cases ojpgco and cgcg (817 peripheral and 203 central) were extracted from 6800 oral biopsy archives of the oral pathology department and were analyzed: age and sex ofthe patients and type and location distribution were obtained our results show that ...

INTRODUCTION Giant cell tumor of the bone is a relatively uncommon tumor. It is characterized by the presence of multinucleated giant cells. The tumor is usually regarded as benign. In most patients, giant cell tumors have an indolent course, but tumors recur locally in as many as 50% of cases. Metastasis to the lungs may occur. Cooper first reported giant cell tumors in the 18th century. In 19...
