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.
Cervarix will not protect against all types of Human Papillomavirus. Cervarix nu va asigura protecţie împotriva tuturor tipurilor de papilomavirus uman. Cervarix does not protect people from diseases caused by infection with HPV types 16 or 18 if they are already infected with Human Papillomavirus type 16 or 18 at the time of vaccination. Cervarix nu protejează persoanele de boala determinată de infecţia cu HPV 16 sau 18 dacă acestea sunt deja infectate cu papilomavirusul uman de tip 16 sau 18 la momentul vaccinării. Being exposed to human papillomavirus HPV.
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 human papillomavirus type 16 lesion that causes genetic alteration and the second hit is mediated human papillomavirus type 16 lesion 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. 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.
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.
Histopathology exam showed a moderate differentiated keratinized squamous cell carcinoma of the conjunctiva without koilocytosis [Figs.
