Ocular surface squamous neoplasia treated with topical interferon {alpha} 2b

Description

A 64-year-old male patient presented with fleshy lesion over the right temporal conjunctiva for the past 3 months with a gradual increase in size. History of trauma and pain was absent, and past history did not reveal any significant ocular/systemic morbidities. Right eye examination showed single 6*8 mm lesion fleshy mass on the temporal aspect of right conjunctiva extending from the limbus, and the surface showed 'corkscrew' vessels, with prominent 'feeder' vessel; impression cytology revealed dysplastic cells consistent with ocular surface squamous neoplasia (OSSN) (figure 1A).
