    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.

    Aim: To implement the HPV genotyping method of fresh head and neck cancer samples in our laboratory. More than half of the patients recognized being chronic alcohol and tobacco users.

    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.

    The association negii cum să trateze 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 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 hpv virus a dna 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.

    Integrarea se produce adesea la nivelul genei E2 care este astfel inactivata; ca urmare a acestui proces rezulta o expresie necontrolata a genelor E6 si E7. Hpv virus rna or dna. Oncoproteinele E6 si E7 perturba ciclul celular prin legarea si inactivarea a doua proteine ale gazdei cu rol important in reglarea diviziunii celulare normale: proteina supresoare tumorala p53 si proteina retinoblastomului pRb. Astfel, legarea proteinei E6 de p53 induce degradarea rapida a acestei proteine supresoare tumorale printr-un proces dependent de ubiquitina4. De asemenea interactioneaza cu proteina pro-apoptotica Bax si determina  rezistenta la apoptoza alaturi de o instabilitate cromozomiala crescuta.

    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 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.

    Histopathology exam showed a moderate differentiated keratinized squamous cell carcinoma of the conjunctiva without koilocytosis [Figs.
