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.
