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 high risk hpv cancer risk 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.

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 high risk hpv cancer risk Human high risk hpv cancer risk 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 high risk hpv cancer risk 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 genetic cancer death and the second hit is mediated by High risk hpv cancer risk infection in the susceptible cells.
Case Report We present a unique case of squamous cell carcinoma high risk hpv cancer risk 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.
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.
The limbic lesion was removed surgically with 2 mm margin of normal tissue and diathermy of the adjacent sclera was done. At the end, the high risk hpv cancer risk temporal defect was restored using a supero-nasal conjunctiva graft fixed in high risk hpv cancer risk 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.
