Department of Ophthalmology, Grigore T. E-mail: moc. We report the detection of HPV 52 in a sample taken from a year-old patient with squamous cell carcinoma of the conjunctiva of the left eye.
The method used for the detection of HPV was real time polymerase chain reaction.
The evolution 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 high risk hpv no cancer neck cancers oral cavity, high risk hpv no cancer, larynxand nonmelanoma skin cancers squamous and basal cell carcinoma.
The association between HPV infection and eye tumors is little explored territory.
În schimb, 85 de femei din mai mult de de femei cărora li s- a administrat vaccinul placebo au dezvoltat leziuni datorate celor două tipuri de HPV. In another clinical trial study performed in women aged 15 to 55 years, all subjects seroconverted to both HPV types 16 and 18 after the third dose at month 7. Într- un alt studiu clinic studiul efectuat la femei cu vârsta între 15 şi 55 ani, toţi subiecţii au prezentat seroconversie, pentru ambele tipuri de HPV 16 şi 18, după cea de a treia doză la luna 7. HPV vaccination is highly effective in preventing infection with the HPV types that cause the majority of cervical cancers. Vaccinarea anti- HPV este foarte eficace in prevenirea infectiei cu tipurile de HPV raspunzatoare de majoritatea cazurilor de cancer de col uterin.
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 of squamous 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 has 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.
The virus infects basal epithelial cells of stratified squamous epithelium. HPV E6 and E7 oncoproteins are the critical molecules in the process of malignant tumour formation. Interacting with various cellular proteins, E6 and E7 influence fundamental cellular functions like cell cycle regulation, telomere maintenance, susceptibility to apoptosis, intercellular adhesion and regulation of immune responses. High-risk E6 and E7 bind to p53 and pRb and inactivate their functions with dysregulation of the cell cycle. Uncontrolled cell proliferation leads to increased risk of genetic instability.
All other ophthalmological findings were normal. Conjunctival culture was performed before surgery, and no bacterial infection was found.
Combating Cervical Cancer
The CT scan of the head and neck showed no signs of tumor invasion of the orbit or the lymph nodes. The limbic lesion was removed surgically with 2 mm margin of normal tissue and diathermy of the adjacent sclera was done.
The aim was to examine the risk of cervical neoplasia in women with SLE, overall and with respect to treatment, compared with women from the general population. The main outcome was defined as a first cervical neoplasia dysplasia or cancer during follow-up. Secondary outcomes were first cervical intraepithelial neoplasia CIN 1; first CIN grades 2—3; and first invasive cervical cancer during follow-up — Cox regression models estimated relative risks adjusted for age, level of education, health-care utilization, number of children, marital status, family history of cervical cancer and prior cervical screening.
At the end, the remaining prostate cancer hormone deprivation therapy 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.
Histopathology exam showed a moderate differentiated keratinized squamous cell carcinoma of the conjunctiva without koilocytosis [Figs.
