Neoplastic lesions of conjunctival and corneal squamous epithelium known as ocular surface epithelial dysplasia range from mild dysplasia, carcinoma in situ to invasive squamous cell carcinoma. Ocular surface squamous neoplasia (OSSN) has a predilection for mitotically active corneoscleral limbus (95%). The incidence of OSSN varies between 0.02 and 3.5/100,000 populations. The most frequent to be affected by these neoplasms are the elderly males of fifth to sixth decade. We highlight case series of five patients presenting with ocular surface neoplasms of which two were immunocompromised. The diagnosis of the few cases was made on cytology and confirmed on histopathology. These cases are discussed to emphasize on the increased incidence of these ocular surface neoplasms.

Ocular surface squamous neoplasia (OSSN) comprises a wide spectrum of dysplastic alterations of the squamous epithelium of the surface of the eye, for example, the cornea and the conjunctiva ranging from "precancerous" lesions to bona fide invasive carcinoma. The epithelial infiltration can range from mild to severe dysplasia (i.e. mild, moderate, or severe corneal intraepithelial neoplasia) to full thickness epithelial dysplasia. We are presenting a case of a 55-year-old male patient who presented with a sudden increase in the size of her pterygium for the last 3 months, which were finally diagnosed to be carcinoma in situ.
