Esophageal squamous papilloma is an uncommon benign squamous epithelial polypoid tumor and is usually identified as a solitary lesion of the lower esophagus. Chronic mucosal irritation and infection with human papilloma virus (HPV) are two proposed etiologies. However, the natural history of esophageal squamous papilloma is unknown, and whether it can develop to esophageal cancer is controversi...

background cervical cancer is the leading cause of death from cancer in under-developed countries. human papilloma virus (hpv) 16 and 18 are the most prevalent types associated with carcinogenesis in the cervix. conventional polymerase chain reaction (pcr), type-specific and consensus primer-based pcr followed by sequencing, restriction fragment length polymorphism (rflp) or hybridization by sp...

The latest experimental data on the role of viruses in the origin of human tumors are discussed. This group of viruses consists of T-cell leukemia virus type 1 (HTLV 1), herpes viruses (HHV 8 and Epstein-Barr virus), hepatitis B virus, and human papilloma viruses. The most typical feature of this group of viruses is a very long latent period from the initial infection to the development of the ...

carcinoma derived from the virus-induced rabbit papillontá has been the subject of numerous stud iss. Early work indicated that the carcinoma (V2) did not contain papilloma virus demonstrable by the usual infectivity tests. Nevertheless, there was reason to believe that papilloma antigen was pres cut in the V2 carcinoma cell, since the host rabbits developed specific papilloma complement-fixin...

This year's Nobel Prize in Physiology or Medicine rewards the discoverers of two viruses that cause major afflictions of humankind. Identifying human papilloma virus (HPV) and human immunodeficiency virus (HIV) might now appear to have been simple, but the way forward was far from obvious at the time.

human papillomavirus (hpv) has also been suggested as an etiology of esophageal squamous cell carcinoma (scc). the aim of this study was to investigate the prevalence of hpv infection in esophageal sccs in our region with strict contamination control to prevent false positive results. thirty cases of esophageal squamous cell carcinomas were chosen by simple random selection in a period of two y...
