Ocular surface squamous neoplasia (OSSN) is a malignant or dysplastic lesion that has its origins in the epithelial cells at the ocular surface. The structures from which these lesions can arise are the conjunctiva, the limbus, and the cornea. Our study was conducted on a group of seven patients with ocular surface squamous cell carcinoma (SCC). Histopathologically diagnosed SCCs were then assessed as well, moderately and poorly differentiated, depending on which area of differentiation dominated in Hematoxylin-Eosin staining. For the immunohistochemical analysis, the following antibodies (markers) were used: Ki67, p53 and B-cell lymphoma 2 (Bcl-2), E-cadherin, and vascular endothelial growth factor (VEGF). Our study group was composed of seven cases of SCCs of the ocular surface. Three were below in T1 American Joint Committee on Cancer (AJCC) stage, two cases were in T2 AJCC stage, and two cases were in T3 AJCC stage. None of our cases were T4, N1 or M1 AJCC tumors. Four of the cases were histopathologically moderately differentiated SCCs of the ocular surface and three were poorly differentiated SCCs. None of the seven patients present human immunodeficiency virus (HIV) infection. P53 immunostaining was strongly present in our study. Bcl-2 overexpression is not a fact that our study highlights. The expression of Ki67 proliferation marker was low in our study. Our study on ocular surface SCC reveals negative assessment of VEGF immunostaining. E-cadherin expression in our study was positive. Ocular surface SCCs are slow growing tumors, with very low metastasis potential, when HIV-infection is not present.
