Clinicopathological Correlates of Ocular Surface Squamous Neoplasia.

This study examined the distribution of histopathological disease severity amongst a cohort of patients treated for clinically suspected ocular surface squamous neoplasia and evaluated the relationship between various patient and clinical factors and the severity of pathological grade as well as treatment outcomes. A retrospective cohort study of demographic and clinicopathological factors of 150 patients clinically diagnosed with suspected ocular surface squamous neoplasia who underwent excision of lesion with histopathological diagnosis. The study included 125 cases; the mean age at diagnosis was 64 years (SD = 11.26). 74% of cases were histologically confirmed as ocular surface squamous neoplasia. Pathological distribution was conjunctival intraepithelial neoplasia I (13.6%), conjunctival intraepithelial neoplasia II (16.8%), conjunctival intraepithelial neoplasia III (21.6%), carcinoma in situ (21.6%), and squamous cell carcinoma (2.4%). Lesion appearance was leukoplakic (18%), gelatinous (15%), dysplastic (11%), vascular (6%), papilliform (2%), nodular (2%). Lesion location was nasal (43%), temporal (42%), and superior or inferior (14%). Recurrence occurred in 7 cases (5.6%). A significant association was found between presence of leukoplakia and pathological grade ( Ocular surface squamous neoplasia is most frequently diagnosed in conjunctival intraepithelial neoplasia III and carcinoma in situ stages, and treatment outcomes are usually favourable.
