Cyst-Like Schwannoma on the Eyelid Margin

Schwannomas are benign tumors originating from Schwann cells. We describe a rare case of solitary schwannoma on the eyelid margin. To our knowledge, this is the first clinical report of such a lesion on the eyelid margin, confirmed by both extensive immunohistochemical analysis and its distinctive morphology. Although schwannomas seldom undergo malignant change, they should be considered in the differential diagnosis of palpebral lesions.
