The following definition is proposed: 'Nevi are visible, circumscribed, long-lasting lesions of the skin or the neighboring mucosa, reflecting genetic mosaicism. With the exception of melanocytic nevi, they do not show neoplastic growth. They never show malignant neoplasia.' -For several types of ...
and the latter is not a pre-neoplastic condition or lesion, it is proposed that focal foveolar hyperplasia should no longer be referred to as "gastric polyp," which would avoid unnecessary follow-up examinations and possibly, ...

However, they also manifest additional antigens that are either absent or expressed in minimal quantities on non-neoplastic cells. These are called tumor-specific or tumor-associated antigens (Fig. 1). Tumor antigens are present as peptides of approximately 8-10 amino acids along with major ...

A polypoid lesion is a tumor that may or may not have a stalk and is located within the colon of the intestines.A polypoid lesion may be either non-neoplastic, or benign, or it may be adenomatous, or cancerous. Polypoid lesions within the colon are only diagnosed through a colonoscopy, ...

Adherence to the intestinal mucosa may also increase bacterial translocation and virulence. The most potent probiotics, therefore, may have increased pathogenicity. The relation between mucosal adhesion and pathogenicity in Lactobacillus spp. is supported by the finding that blood culture isolates of ...
HPV L1VLP vaccination induces high titers of genotype-restricted neutralizing antibodies and is highly effective at preventing HPV infection and thereby the neoplastic diseases they cause [96]. It is also reported that antibody titers for 9vHPV are 10–100-fold higher than that of natural infection...
Many mechanisms are used by infectious agents to survive in a host and create favorable conditions for neoplastic transformation. It is also possible that a child can inherit mutations that occurred in the germ cells of the parents via viral mutagenesis. Partial sequences of HHV-6A have been ...
