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.  ...

â  â  background esophageal squamous cell carcinoma (escc) is usually detected in advanced stages resulting in a very poor prognosis. early diagnoâ­sis needs identification of clinically relevant precancerous lesions which could become the target of screening and early treatment. our aim was to check whether esophagitis could serve as a relevant histological precursor of escc in northern iran. ...

Background The oral squamous cell carcinoma (OSCC) is a malignant neoplasm originating from the epithelial lining of the oral cavity, accounting for about 95% of malignant lesions in this region.

In 2012, Brazil was estimated at 9,990 new cases of oral cancer in men and 4,180 in ...

Verrucous carcinoma (VC) is an exophytic, low-grade, well-differentiated variant of squamous cell carcinoma. It is described as a lesion appearing in the sixth or seventh decade of life that has minimal aggressive potential and, in long-standing cases, has been shown to transform into squamous cell carcinoma. Oral submucous fibrosis (OSMF) is a potentially malignant disorder, and about one-thir...

conclusions prognosis of this type of tumor, apart from its size and differentiation level, depends on infiltration in tumor-surrounding tissue, perineural and perivascular spread. therefore, it is always necessary to analyze the removed skin especially on margins. introduction squamous cell carcinoma is the most common type of lip and oral cavity cancers. in majority of cases it follows quite ...
