Background and aims. Various morphologies are seen in different salivary gland tumorsor within an individual tumor, and the lesions show divers biological behaviors. Experimental results support the hypothesis that increased CrkII proto-oncogene is associated with cytokine-induced tumor initiation and progression by altering cell motility signaling pathway. The aim of this study was to assess t...

metastatic lesions represent 1-8% of all malignant tumors of the mouth and jaws, which are regarded as rare sites of metastases from different primary tumors. metastases in mouth soft tissue are also rare, and within these it is on the gums where they more frequently occur. primary tumors which metastasize to the mouth are most commonly: lung, breast, and kidney. clear cell carcinoma is the mos...

Several proliferation markers, such as DNA ploidy, Ki67, MiB1 and proliferating cell nuclear antigen have been shown to correlate with clinical course and prognosis in several epithelial tumours and lymphomas. In the present study, the prognostic relevance of these markers was evaluated in major salivary gland carcinomas. A sample of 36 cases out of 85 patients submitted to surgery for major sa...

primary de novo intraosseous carcinoma is a rare neoplastic lesion which commonly occurs in the jaws. it is an epithelial odontogenic malignancy arising from odontogenic epithelial residues in the bone rather than from a preexisting epithelial lesion. in the present case report, the clinical, radiological and histological features of primary de novo intraosseous carcinoma are discussed and its ...

BACKGROUND The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. MATERIALS AND METHODS Fifty thre...
