Squamous Cell Carcinoma of Conjunctiva - A Rare Interesting Case
Journal Title: International Journal of Research and Review - Year 2017, Vol 4, Issue 11
Abstract
Background: Squamous cell carcinoma, a malignant tumour of squamous epithelium, is very rare in conjunctiva, though most of the exposed part of conjunctiva lined by stratified squamous epithelium which is often exposed to all kind harmful and damaging effects including exposure to ultraviolet radiation from the sunlight. Squamous cell carcinoma of conjunctiva, which is termed as the end state of ocular surface squamous neoplasia (OSSN) which includes intraepithelial neoplasia has a very low incidence, which is in the range of 0.02 to 3.5 per 100 000 population. The incidence of squamous cell carcinoma is relatively higher in the countries such as Australia which fall in the region of low latitudes of equator. Squamous cell carcinoma of conjunctiva occurs more commonly in elderly males and the most common risk factor for higher incidence of conjunctival squamous cell carcinoma exposure to sunlight, other less common risk factors include vitamin A deficiency, chronic infections as trachoma, HPV, chronic irritations with dust or other factors and HIV infection. Squamous cell carcinoma of the conjunctiva occurs more commonly in corneal limbus and presently grossly as gelatinous, velvety or papilliform, leukoplakic, nodular and diffuse. Presented here is an interesting case of moderately squamous cell carcinoma which presented as tiny recurrent mass which was obviously being resected previously other obviously non-neoplastic reasons.
