Abstract:
A 50-year-old woman suffered from recurrent swelling and inflammation in the region of the medial portion of the lower eyelid 24 years after right-sided dacryocystorhinostomy. The tumor was removed in two stages under histological control of the excision margins. No evidence for malignancy was found. During the follow-up period of 4 years the patient remained recurrence free and without complaints. The diagnosis reached was an extraorbital hemangiopericytoma.
