Ocular surface squamous neoplasia (OSSN) presents as a spectrum from simple dysplasia to carcinoma in situ to invasive squamous cell carcinoma involving the conjunctiva as well as the cornea. It is a distinct clinical entity although it has been known by a variety of different names throughout the literature. Most commonly, it arises in the limbal area, occurring particularly in elderly males who have lived in geographic areas exposed to high levels of ultraviolet-B radiations. Symptoms of OSSN range from none to severe pain and visual loss. The development of preoperative diagnostic techniques, such as impression cytology, is of value in clinical decision-making and for follow-up. Simple excision with adequate margins is currently the best-established form of treatment, despite other modalities. The course of this treatment is evanescent but is more frequently slowly progressive and may require exenteration and occasionally may lead to death. In this article, we report a case of OSSN in a 76-year-old male farmer, who presented with complaints of subconjunctival hemorrhage of the left eye. Excisional biopsy was done. Histopathological examination revealed a well-differentiated squamous cell carcinoma.
