Squamous differentiation papilloma

Case Report

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 squamous differentiation papilloma, 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 squamous differentiation papilloma. 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 squamous differentiation papilloma surgical removal of the tumor and the patient was explained that long-term follow-up is essential to avoid recurrence.

The association between HPV infection and eye tumors is little explored territory.

Di Girolamo brings forward a two-hit theory that squamous differentiation papilloma 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.

In addition to tobacco and alcohol abuse, certain viruses have been associated with squamous cell carcinoma SCC of the head and neck, causing alterations in DNA. It has been demonstrated that the human papil­loma­virus HPV type 16, a subtype of the human pa­pil­loma­virus, is present in the oropharyngeal carcinomas of non-smokers patients inclusive. HPV-infected cells express some viral proteins encoded by genes called E6 and E7, and can inactivate p53 protein and the retinoblastoma-type pro­tein RBP involved in squamous differentiation papilloma regulation of proliferation and cell death.

Case Report Squamous differentiation papilloma 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 squamous differentiation papilloma.

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 squamous differentiation papilloma 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 squamous differentiation papilloma 4°C until processing.

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