Squamous Cell Carcinoma of Conjunctiva: A Case Report

Squamous cell carcinoma (SCC) of conjunctiva is a rare tumor of the ocular surface with an incidence rate of 0.02 to 3.5 per 100, 000. It usually arises at the limbus as papillary exophytic grey-white mass. The main risk factors for both are exposure to solar ultraviolet radiation outdoors, HIV/AIDS, human papilloma virus and allergic conjunctivitis. We report a case of 64 years old male presenting with complaints of swelling and pain in left eye since 1 year. Complete enucleation was done. Histopathologically, it was diagnosed as well differentiated squamous cell carcinoma. There was a past history of similar complaints 4 years ago for which excision biopsy specimen was diagnosed as well differentiated squamous cell carcinoma following which patient underwent 4 cycles of chemotherapy. Thus, the final diagnosis of recurrent squamous cell carcinoma of conjunctiva was made. To conclude, Squamous cell carcinoma has high recurrence rate of 5 to 56 %. So, complete orbital enucleation with adequate surgical margins should be done followed by adjuvant therapy to prevent recurrence.
