Conjunctival Squamous Cell Carcinoma Due to Ocular Prostheses: A Case Report and Review of Literature

Conjunctival squamous cell carcinoma (SCC) is a rare finding in everyday clinical practice, but is the most common malignancy of the ocular surface. The incidence of this malignancy in the United States is 0.03 per 100,000 persons. It is one extreme of a spectrum of lesions encompassed in ocular surface squamous neoplasia which range from dysplasia to carcinoma in situ to invasive SCC. Exposure to ultraviolet radiation B (UVB), human papilloma virus (HPV), and human immunodeficiency virus (HIV) infection of eroded ocular surface are important risk factors predisposing to the development of this malignancy. Herein we report a case of SCC arising in chronic conjunctival irritation due to prolonged prosthetic use following enucleation for traumatic eye injury.
