A 51-year-old woman consulted for a painless, painless and firm tumour on the left upper eyelid that was recurrent and perceptible to the touch. She was also found to have associated blepharochalasis and eyelid bags.

The patient reported a history of transconjunctival excision of a chalazion 2 years earlier, with recurrence of the lesion shortly afterwards. The ocular functional examination was normal.
We requested a contrast-enhanced CT scan of the facial mass, in which we found a solid formation in the supero-external region of the orbit, without involvement of the eyeball, with the diagnosis of a presumed lacrimal gland tumour.

We decided, in agreement with the patient, to carry out surgical resection of the tumour and at the same time perform an associated upper and lower cosmetic blepharoplasty.
The intraoperative finding of the lesion was a left palpebral formation measuring 1 x 0.8 x 0.5 cm in diameter, with a smooth surface and elastic consistency, which did not invade ocular structures and which we were able to remove completely. The upper blepharoplasty was performed according to the classic technique and the lower blepharoplasty was performed transconjunctivally, with removal of both the upper and lower palpebral bags.

The patient's postoperative evolution was good, without complications, with a very satisfactory aesthetic result and no tumour recurrence after 12 months of follow-up.

The anatomopathological study of the resection specimen showed that the tumour was benign, non-infiltrative, with a well-defined capsule, consisting of fascicles of spindle cells arranged in a whorled or swirling pattern alternating with more lax areas (Antoni A and B patterns respectively); with no signs of atypia. Immunologically, the S-100 protein was positive, confirming the diagnosis of eyelid schwannoma.
