INTRODUCTON: Many lesions of the jaws contain giant cells, they include Peripheral giant cell granuloma, Central giant cell granuloma, aneurismal bone cyst, brown tumor of hyperparathyroidism and early stage of cherubism. Giant cell granuloma which is a benign bone lesion that occurs mainly in the jaws are not tumor but tumor like conditions, the cause of tumor like condition is chronic truma w...

A 28-year-old man presented with a chest radiograph strongly suggestive for cardiomegaly. Although he did not consent any hemodynamic studies, cardiomegaly was ruled out on the basis of the clinical course. Computed tomography showed the existence of a large mass in both sides of the heart and in both lower hemithoraces. The tumor was resected by anterior mediastinotomy; it was weighted 2100 g ...

1. High-speed cinematography of the escape behaviour of freelymoving crayfish showed that the thoracic and abdominal appendages exhibit stereotyped movements in giant axon-mediated tail flips and in non-giant flips. Three distinct classes of non-giant tail flips were recognized in this study: linear, pitching and twisting flips. 2. In medial giant flips and linear non-giant flips the chelipeds ...

Giant granules ( 1 sm in diameter), Auer rods, and unique giant granules that contained crystalloid material were investigated in monoblasts from a patient with acute monocytic leukemia using ultrastructural and cytochemical techniques. The latter granule type differed from abnormal granules previously described in leukocytes. In Wright’s stained preparations, these granules appeared to be crys...

Giant cell myocarditis is a serious and frequently fatal inflammatory heart disease of which the etiology remains unknown. In the present study, we investigated the origin of multinucleated giant cells in myocarditis with the use of an experimental model. We also examined the factors relating to the formation of giant cells in myocarditis. Severe myocarditis characterized by the appearance of m...

background: although giant cell tumor (gct) is considered to be a primary benign bone tumor, its aggressive behavior makes its diagnosis and treatment, difficult and challenging. this is especially true in distal radius where gct appears to be more aggressive and difficult to control locally. we report our clinical outcome of en-block resection and reconstruction with non-vascularized fibular a...

we report occurrence of a rare case of giant cell tumor (gct), in a 28-year old woman, arising from anterior arc of right 6 th rib during pregnancy. it progressed rapidly during breast-feeding period, mimicking malignant bone tumor at delayed presentation.

Inflammatory endobronchial polyp is a rare disease mostly encountered in asthmatic patients. Chronic airway and foreign material irritation or thermal injury may result in the formation of granulated tissues and become polypoid mass. Herein, we describe a 52-year-old man with severe respiratory distress and infection with 35 years history of smoking. He had an obstructive pattern in his pulmona...

BACKGROUND Giant binuclear oocytes occur with considerable frequency in human ovaries, but their ultimate fate remains unknown. We report the morphology, cytogenetics and developmental potential of human giant oocytes from patients undergoing assisted reproductive technologies. METHODS AND RESULTS A total of 44 giant oocytes was collected from patients aged 22-44 years old, with an overall fr...

The zebrafish has become an important genetic model, but their small size makes them impractical for traditional physiological studies. In contrast, the closely related giant danio is larger and can be utilized for physiological studies that can also make use of the extensive zebrafish genomic resources. In addition, the giant danio and zebrafish appear to exhibit different growth types, indica...
