Limbal schwannoma: Clinicopathological study of a case with review of literature.

Schwannomas involving the perilimbal conjunctiva is an extremely rare clinical entity and has been reported scantily in literature. In this case, a 27-year-old healthy female presented with a pinkish smooth globular mass involving the limbus in the superonasal quadrant of the left eye. The mass was completely excised and histopathology revealed an encapsulated tumor, with cells displaying elongated nuclei, bland chromatin, and few Verocay bodies with palisaded nuclei, suggestive of schwannoma. Immunohistochemistry showed strong S100 positivity. This case thus highlights schwannoma as a differential diagnosis of limbal masses.
