An unusual case with corneal and conjunctival neoplasia (dysplasia) is reported. The patient was a 33-year-old male having complaints of foreign body sensation and blurred vision in the right eye. There were nasal and temporal pingueculae in his right eye, and its corneal epithelium formed a semitranslucent membrane-like gray plaque temporally. The gray plaque with fimbriated edges extended over the visual axis. After scrapping of the diseased corneal epithelium and removal of its adjacent conjunctival tissue, followed by cryotherapy, the cornea recovered its transparency. On cytological and histopathological examination, a diagnosis of corneal conjunctival intraepithelial dysplasia was made.
