A 79-year-old male, not a diabetic or hypertensive, presented to the outpatient department with pigmented painless lesions in the temporal quadrant of his right eye for 3 years without visual impairment. The intraocular pressure was normal and the media was clear. The two melanomatous lesions were firm, and nodular with neovascularization [Figure 1]a. The temporal lesion was freely mobile. The limbal mass with restricted mobility was excised for biopsy. Histopathological evaluation suggested multiple foci of carcinomatous proliferation involving the squamous epithelium lining the limbal nodule with typical keratin pearls [Figure 1]b. The sub-epithelial tissues showed several melanophores and lymphocytic infiltration with neovascularization, suggestive of moderately differentiated pigmented squamous cell carcinoma of the bulbar conjunctiva, a rare entity. Metastatic work-up was negative. Ultrasound biomicroscopy excluded involvement of the ciliary body and iris [Figure 2]. The other conjunctival mass was widely excised with 4–6 mm margins using the ‘no-touch’ technique, cryotherapy of the conjunctival margins, alcohol kerato-epitheliectomy and amniotic membrane transplantation with glue under local anaesthesia. The patient remains well at 3 years’ follow-up [Figure 3].
