Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology.

background: salivary gland tumors are relatively uncommon and they consist of 3-10% of head and neck neoplasms. most of studies have shown geographic variation in the incidence and histopathologic types of salivary gland neoplasms. the aim of this study was to evaluate the salivary gland tumors in isfahan for 10 years duration. materials and methods: in this epidemiological study, 229 medical r...

In infants and children, pancreatic neoplasms occur uncommonly. Histologically, these tumors can resemble pancreatic embryonic elements or more well-differentiated pancreatic structures, in a subset the cellular origin can’t be delineated. This review discusses three of the most classic pediatric pancreatic neoplasms: pancreatoblastoma, solid pseudopapillary neoplasms and pancreatic endocrine n...

Biliary (hepatic and extrahepatic) intraductal papillary mucinous neoplasms and intraductal oncocytic papillary neoplasms/carcinoma are rare neoplasms. Classification of biliary intraductal papillary tumors can be confusing and reports in radiology literature are extremely limited. We describe the first reported case of biliary intraductal oncocytic papillary neoplasms/carcinoma in the liver in...

background: early detection and screening have been successful in reducing mortality in some countries, but not in others. this is most of due to poor management and implementation of inappropriate policies. all of patients with cervical cancer are in developing countries. the effectiveness of screening for cancer of the cervix in these countries is dramatic. it seems that after 50 years pap sm...

results like other cancers, prostate cancer is caused by an accumulation of genetic alterations in a cell that drives it to malignant growth. specific genes and gene alterations have been suggested to play a role in its development and progression. aneuploidy, loss of heterozygosity, gene mutations, hypermethylation and inactivation of specific tumour suppressor genes such as gstpi, apc, mdr1, ...

breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...
