Three tumors initiated by well characterized viruses, but in which virus is not detectable by ordinary virological techniques, are discussed. The question of the possible state of the virus within these seemingly non-infectious tumors is considered, largely from the standpoint of findings with the rabbit papilloma virus. This agent in its natural host, the cottontail rabbit, is infective, can b...
background and objective: to estimate the risk of human papilloma virus (hpv) infection for cervical malignancies, we conducted a case-control study in southern iran (hormozgan province). materials and methods: for this purpose,52 paraffin embedded blocks with exact diagnosis of cervical carcinoma(50 carcinomas and 2 carcinomas in situ) from 2001 to 2006 and 52 praffin embedded blocks of cervic...
Bovine papilloma antigen detected by fluorescent antibody was correlated with the appearance of infectious virus and with epithelial hyperplasia and hyperkeratinization in the developing bovine cutaneous papilloma. Neither antigen nor infectious virus was found in the earliest stages of growth characterized by connective tissue pro liferation and by little or no epithelial change. The cellular ...
Focal epithelial hyperplasia (FEH) or Heck’s disease is a rare viral infection of the oral mucosa caused by human papilloma virus especially subtypes 13 or 32. The frequency of this disease varies widely from one geographic region and ethnic groups to another. This paper reports an Iranian case of extensive focal epithelial hyperplasia. A 35-year-old man with FEH is described, in whom the lesio...
The Bug Breakfast topic for October was Human Papilloma Virus (HPV). The presenters covered the epidemiology of HPV, the newly introduced HPV vaccine and social and psychological issues relating to HPV vaccination.
Abstract Sarcoid tumors were described by means of histopathological and molecular procedures in a 5-year-old donkey. Histopathological examination showed epithelial changes including hyperkeratosis, hyperplasia, koilocytosis, rete peg formation. Neoplastic fibroblastic cells plumb, large spindle to stellate embedded dense collagenous tissue. Results Polymerase Chain Reaction DNA sequence analy...
To identify the genetic events which may play a role in the development of cervical carcinoma, we performed a detailed allelotype analysis utilizing DNA from 53 primary tumors and corresponding normal cells and 57 polymorphic probes mapped to each of the chromosomal arms, excluding the short arms of the acrocentric chromosomes. Loss of heterozygosity (LOH) of >25% was observed at sites on 11 ch...
Cervical cancer is the second most common malignancy and a leading killer among women worldwide. Seventy percent of these cervical cancers are known to be caused by Human Papilloma Virus, which is transmitted primarily by sexual contact. The use of Human Papilloma Virus prophylactic vaccine among young adolescents, who have not been previously exposed to the infection, as primary prevention hol...
Buschke-Löwenstein tumor is a rare manifestation of a sexually transmitted human papilloma virus infection that affects the anogenital area. Wide local excision of the lesion is the mainstay of treatment. Malignancy though must be excluded.
Introduction Cervical cancer is still a major health problem in Tunisia and over the world. HPV infection may induce malignant transformation of lesions, especially in case of colonization by oncogenic HPV genotypes. Early detection of viral genome by molecular biology in women with normal cytology in cervical screening test (CST) can be a part of a screening policy to improve cancer prevention...
