Introduction: Multinucleated giant cells are often encountered in oral lesions. An understanding of the histogenesis of these giant cells can give us an insight on the pathologic process in progress. Traditional classifications have placed little importance on the type or histogenesis of multinucleated giant cells in grouping these lesions. Objectives: (a) To classify giant cell lesions based o...

  Background and Objectives: Giant cell Tumor of bone (GCT) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. Histological features of the tumor often could not predict its future biologic behavior, so it is just called ''Giant cell tumor'' without indicating maligna...

Giant cell tumor, excluding its prototype in bone, is usually a benign but local aggressive neoplasm originating from tendon sheath or soft tissue. Malignant behavior is uncommon. Visceral organ involvement including urinary bladder is rare. Giant cell tumors in visceral organs usually accompany epithelial tumors and the clinical behavior of giant cell tumor in urinary bladder is similar to its...

Tomato (Lycopersicon esculentum Mill.) seedlings, susceptible (cv. Pearson A-I Improved) and resistant (cv. Pearson Improved) to race 1 Fusarium oxysporum f. sp. lycopersici (Sacc.) Snyd &Hans., were inoculated with Meloidogyne javanica (Trueb) Chitwood second-stage juveniles and 3 weeks later with race 1 F. oxysporum f. sp. lycopersici spores. One week after fungal inoculation, no fungus was v...

Giant cell tumours are common bone tumours usually benign which arise at the metaphysis and extend towards the epiphysis of bone. A case of giant cell tumour in the distal humerus which is a rare site is presented here. Radiological investigations and biopsy in a 20 year old male who presented to our orthopedic department with elbow pain, led to a diagnosis of giant cell tumour at the medial ep...

Giant cell arteritis is a granulomatous vasculitis of large and medium sized arteries manifesting as temporal arteritis and/or polymyalgia rheumatica. The histological assessment of temporal artery biopsies is frequently encountered in anatomical pathology and has important diagnostic consequences in patients clinically suspected of having giant cell arteritis. We present an intriguing case of ...
