We present a case of 53 years old male who developed reddish thickening on sclera and was diagnosed as scleral maltoma after investigations. Primary scleral involvement remains only a theoretical possibility and has never been documented in literature except for one odd case report where orbital lymphoma was misdiagnosed as scleritis but later proved to be of conjunctival origin by histology.1 This case report has been brought up to highlight the technical challenges faced in planning and execution of external radiation therapy in primary scleral lymphoma.
