S CHWANNOMA is the proper name for tumors developing from the Schwann cells of the neural sheath in preference to the older terms, neurilemomma and neurinoma, since the latter designate tumors containing connective tissue elements ( ie, neurofibromata).1 Conjunctival schwannoma is a rare tumor. Páez Allende2 surveyed the world literature in 1945. He was able to find only three such tumors, apparently arising from peripheral nerves of the bulbar conjunctiva, and added a case of his own.

Dabezies and Penner4 reported a case containing both schwannomatous and neurofibromatous elements.
