Abstract:
The case is presented of a 57 year-old man with a one-year history of enlargement of the left upper eyelid. An excisional biopsy was performed, and the histological and immunohistochemical study confirmed the diagnosis of schwannoma. Schwannomas are benign peripheral nerve sheath tumours, derived from a Schwann cells proliferation. Eyelid involvement is extremely uncommon. To make the diagnosis, a detailed histopathological and immunohistochemical study is essential. This case suggests that schwannomas should be included within the differential diagnosis of any solid eyelid lesion.
