E-mail: moc. We report the detection of HPV 52 in a sample taken from a year-old patient with squamous laryngeal squamous papillomas carcinoma of the conjunctiva of the left eye. The method laryngeal squamous papillomas for the detection of HPV was real time polymerase chain reaction.
Romanian Journal of Rhinology - In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. It has been demonstrated that the human papillomavirus HPV type 16, a subtype of the human papillomavirus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. Specificații HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and laryngeal squamous papilloma pathology retinoblastoma-type protein RBP involved in the regulation of proliferation and cell death.
Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory. More than half of the patients laryngeal squamous papillomas being chronic alcohol and tobacco users.
Conclusions: The genotyping method was validated according to kit instructions.
To get a general idea on the prevalence of HPV genotypes in head and neck cancer in our region we tested a very small number of samples. Ferlay J, Soerjomataram I et al.
The laryngeal squamous papillomas was favorable after surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence. Keywords: Conjunctiva, eye, human papillomavirus 52, real time polymerase chain reaction, squamous cell carcinoma Human papillomavirus HPV infection is strongly associated with anogenital tumors cervix, penis, vulva, vagina, anushead and neck cancers oral cavity, esophagus, larynxand nonmelanoma skin cancers squamous and basal cell carcinoma.
The association between HPV infection and eye tumors is little explored territory. Di Girolamo brings forward a two-hit theory that explains cancerogenesis in OSSN: The first hit is mediated by ultraviolet radiation exposure that causes genetic alteration and the second hit is mediated by HPV infection in the susceptible cells.
Case Report We present a unique case laryngeal squamous papillomas laryngeal squamous papillomas squamous papillomas cell carcinoma of the conjunctiva examined and treated in June The year-old patient presented at the Ophthalmology Department for mild stinging sensation and redness in the left eye for almost 1-year and a half.
He laryngeal squamous papillomas been treated for the last 2 months with dexamethasone eye drops for scleritis by another ophthalmologist. The patient admits being a heavy smoker for almost 30 years and that in his free time he practices agriculture without using sunglasses.
All other ophthalmological findings were normal. Conjunctival culture was performed before surgery, and no bacterial infection was found. The CT scan of the head and neck showed no signs of tumor invasion of the orbit or the lymph nodes.
Squamous cell papilloma The limbic lesion was removed surgically with 2 laryngeal squamous papillomas squamous papillomas margin of normal tissue and diathermy of the adjacent sclera was done.
At the end, the remaining temporal defect was restored using a supero-nasal conjunctiva graft fixed in position with interrupted and surjet The excised tumor was cut into 2 fragments: One for pathology preserved in formalin and one for HPV genotyping preserved in Cobas polymerase chain reaction PCR solution and refrigerated at 4°C until processing.
Laryngeal squamous papillomas. More than half of the patients recognized being laryngeal squamous papillomas alcohol and tobacco users. Conclusions: The genotyping method was validated according laryngeal squamous papillomas kit instructions.
Histopathology exam showed a moderate differentiated keratinized squamous cell carcinoma of the conjunctiva without koilocytosis [Figs.
