ABSTRACT
Schwannoma is a relatively rare benign tumour of peripheral nerve origin. The occurrence
of Schwannoma in eyelid is extremely rare. As per our knowledge, only 11 such cases
have been reported in the literature so far. We present a case of a 40-year-old man
who presented to us with a 2-year history of slowly enlarging, painless mass in his
left upper lid with resultant progressive ptosis. Ocular examination was suggestive
of a firm, non-tender nodule of size 2 × 1.5 × 1 cm on the left upper lid. The mass
was non-adherent to the skin or the underlying tissue. The eyelid skin and conjunctiva
were indurated and signs of inflammation were present. The lateral part of eyelid
showed presence of an ulcer and the lid function was severely hampered. Provisional
clinical diagnosis was that of an eyelid malignancy. With this in mind, the medial
part of the lid was excised and reconstructed using a tarso-conjunctival flap from
the lower eyelid in conjunction with a skin graft. The histopathology and immunohistochemistry
established the diagnosis of Schwannoma. We recommend that Schwannoma be considered
in the differential diagnosis of well-circumscribed eyelid swellings.
