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 and neck cancers oral cavity, esophagus, larynxand nonmelanoma skin cancers squamous and basal cell carcinoma.
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 high risk hpv cervical cancer, 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.
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 high risk hpv cervical cancer 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.
Глазу, однако представлялось, что у него нет каких-то определенных физических границ, а окружает его нечто из полупрозрачного голубовато-зеленого материала, светящегося мягким внутренним светом.
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 high risk hpv cervical cancer 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 high risk hpv cervical cancer graft fixed in position with interrupted and surjet The excised tumor was cut into 2 fragments: High risk hpv cervical cancer 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 cauze cancer la colon moderate differentiated keratinized squamous cell carcinoma of the conjunctiva without koilocytosis [Figs.
Думаю, что все правильно, - сказал он. - Во всяком случае, мы сейчас увидим. Экран засветился, но вместо ожидаемой картины на нем появилось несколько обескураживающее сообщение: ОБРАТНЫЙ ОТСЧЕТ НАЧНЕТСЯ, КАК ТОЛЬКО БУДЕТ ВВЕДЕН КОНТРОЛЬНЫЙ ТЕМП - Глупо, - пробормотал Хедрон.
