adenomatoid odontogenic tumor (aot) is a benign odontogenic tumor with slow but progressive growth. the three variants: follicular, extra follicular (both central type), and peripheral present withidentical histologic findings. this case report describes a patient with a large aot in the mandibleof the extra follicular type which is the less common of the two central types. it also strikes as a...

Multiple synchronous primary lung cancers presenting with different histologic types are uncommon. Among reported cases with different histologic findings, only a few had small cell lung cancer (SCLC) and adenocarcinoma. This unusual combination of lung cancers has not been well reported. In this report, we describe two cases of synchronous primary lung cancer presenting with lymph node metasta...

OBJECTIVE Although pancreatic cancer has an extremely high case fatality rate, little is known about differences in mortality by histologic types. We examined median survival and risk of mortality for endocrine pancreatic tumors and two types of exocrine tumors, adenocarcinomas, and mucinous tumors. METHOD This analysis included 35,276 pancreatic cancer cases reported to the nine population-b...

Cancer of the urinary bladder is a commonly encountered malignancy tract. The most common histologic type Transitional cell carcinoma (TCC). It accounts for 90-95% all cancers. usually seen in sixth and seventh decades life. Men are affected three to four times more than women. remaining 5-10% tumors other types epithelial mesenchymal tumors. Squamous (SCC) very uncommon malignancy.

PURPOSE A number of different genes are known to be inactivated by aberrant hypermethylation in breast cancer, but it is still unknown to what extent these epigenetic alterations differ according to specific breast cancer phenotypes. We sought to determine whether the extent of hypermethylation or defined profiles of gene hypermethylation are associated with biological characteristics of breast...

Thymic epithelial tumor is a distinctive pathologic entity exhibiting variable histologic features and heterogeneous oncologic behavior. Among the various classification systems, that of the World Health Organization has been adopted because of good correlation between histologic appearance and oncologic behavior. Radiologically, a smooth contour and round shape are most suggestive of a type-A ...
