OBJECTIVES To investigate the clinical characteristics and pre- biopsy provisional diagnoses of benign oral mucosal tumors. MATERIAL AND METHODS A 10- year retrospective analysis of all benign tumors of the oral mucosa, from a university- affiliated oral and maxillofacial surgery department. RESULTS 146 benign tumors were included. The mean age was 49.6 years, with an approximately equal ge...

many types of cancers develop in the oral and maxillofacial region. squamous cell carcinoma is the most common cancer and constitutes over 90 percent of these tumors. malignant transformation is a genetic process, which later makes a phenotyping change at the cellular level. some cancers such as oral squamous cell carcinomas (osccs) develop from pre-malignant lesions and conditions. despite adv...

Hemangiomas are defined as soft tissue lesions in the maxillofacial or oral region. Hemangiomas of salivary glands constitute 30% of the non-epithelial tumors in major salivary glands.  Benign tumors in salivary glands are located 85% in parotid gland and 13% in submandibular gland. We present a case of submandibular hemangioma in an infant patient that had some complications and a challenging ...

Within a single tumor clone, cells have significantly different abilities to proliferate and form new tumors. This has led to the hypothesis that most cells in a cancer have a limited ability to divide and only a small subset of distinct cells, the cancer stem cells (CSCs), has the capacity to self-renew and form new tumors . It has been proposed that the development of tumors is based exclusiv...

Induction of FOXM1 expression by E6 oncoprotein via the MZF1/NKX2-1 axis is responsible for soft-agar growth, invasiveness, and stemness in HPV-positive oral and lung cancer cells. Among patients, the presence of HPV16/18 DNA was positively correlated with NKX2-1 and FOXM1 expression in oral and lung tumors. When oral or lung cancer patients were individually divided into four subgroups by two ...

lipomas are rare benign soft tissue mesenchymal neoplasms in the oral cavity, representing 1% of all benign oral tumors. fibrolipoma (fl), an uncommon, histological variant of the classic lipoma, mostly affects the buccal mucosa. very few cases of fl have been reported in the english literature. to the best of our knowledge a review of the english literature showed 33 cases of fl affecting the ...

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...

conclusions with the average 89 months follow-up, no recurrence of the diseases was found in the patients. it seems that using of cement and oral anti-parasitic, after extensive resection of the lesion is a proper treatment of bone hydatid disease. introduction bone is an uncommon site of involvement in hydatid disease; with the prevalence of 0.5-2% among bone lesions. case presentation in this...
