Keywords carcinoma, floor of the mouth, mandible resection, neck dissection Rezumat Cu o prevalenţă inferioară tumorilor maligne ale limbii, tu­mo­ri­le maligne de planşeu anterior impun o abordare chi­rur­gi­ca­lă la fel de radicală, cu o margine de siguranţă mare şi cu ma­nage­mentul problemelor de la nivelul gâtului.

HPV-infected cells express some viral proteins encoded by genes called E6 and Hpv lesion tongue, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in the regulation of proliferation and cell death. Materials and method.

We present an immunohistochemical study conducted to identify significant tumour markers in tonsillar SCC.

More than half papilloma lesion on tongue the patients recognized being chronic alcohol and tobacco users. Materials and method. We realized a retrospective study in the Bucur Maternity, that involved the evaluation of the colposcopy registers from to Among patients evaluated by colposcopy we selected the patients whose initial cytological diagnosis was LSIL. Conclusions: The genotyping method was validated according to kit instructions.

We present the sta­tis­tically significant correlations between the presence of immunohistochemical hpv lesion tongue and studied local re­cur­rence, lymph node recurrence and risk of a second can­cer in the aerodigestive upper tract. The de­mon­stration of HPV in tonsillar tumour tissue requires in situ hybridization or polymerase chain reaction PCR for the evidence of viral genome included into the host cell.

Im­pli­caţiile practice ale unui rol etiologic al HPV-ului în can­ce­rele de cap şi gât, în general, şi în CCS de amigdală, în par­ti­cu­lar, reprezintă un subiect în dezbatere, fiind în relaţie cu prog­nos­ticul, tratamentul şi prevenţia acestor tipuri de can­cere. Cuvinte cheie carcinomul cu hpv lesion tongue scuamoase de amigdală CCS HPV markeri tumorali Introduction The tonsillar squamous cell carcinoma SCC is becoming a public health problem because of its rising incidence hpv lesion tongue the last 20 years, in contrast to the decreasing incidence of carcinomas in other subsites of head and neck associated to the reduced prevalence of hpv impfung depression.

These tumours of oral cavity, oropha­rynx, larynx, hypopharynx and sinonasal region are linked by common hpv lesion on tongue, including a male predominant appearance in the 5th-6th decade of life, an important etiological link with tobacco, alcohol use or betel nut chewing, and a histopathological resemblance 1. Data regarding the epidemiology revealed that in Romania the oropharyngeal cancer represents 2.

As in cervical cancers, the oropharyngeal infection with HPV is a sexually transmitted disease which involves some hpv lesion tongue of sexual behaviour: a large number of vaginal sex partners, oral and anal sex.

The anatomical sites preferred by HPV in oropharynx are the tonsils and the tongue, hpv lesion tongue of the unique presence of transitional mucosa in oropharynx and particular in tonsillar tissue, which presents important histological similarities with the cervical mucosa. Tonsillar epithelium invagination may favour virus capture and promote its access to basal cells the only dividing cells in the epithelium.

The tonsillar tissue could be a reservoir for HPV in the upper aero digestive tract. Viermisori la copii simptome Human papillomavirus recombinant vaccine We hpv feigwarzen behandlung two premises for our study on tonsillar cancers. The second consists in the fact that mutagens such as hpv lesion on tongue, alcohol and HPV viral oncogenes E6 and E7 induce dysfunctions of two major mechanisms of cellular cycle, which involves the p53 and RBP tumoral suppressor genes 2.
