A female aged 42 years presented to us for routine eye examination and was found to have a well-circumscribed, firm, smooth, oval nodule at the limbus of the right eye. It had increased slowly to the present size in 7 years. It is unique in being the first and largest limbal schwannoma to be reported from India. The patient had no visual or cosmetic concern. Excision followed by histopathologic evaluation revealed its nature. Special staining (S100 and reticulin) revealed it to be of neurogenic origin. Schwannomas of ophthalmic interest include those arising from the orbit. Within the globe, they have been reported to arise from the uvea. Conjunctival schwannomas are extremely rare. Role of gene mutation as a causal factor has been studied when schwannoma occurs as a part of Carney complex. Association with multiple neurofibromatosis is also documented.
