Primary liposarcoma of the orbit.

Liposarcoma is the most common sarcoma in adults, but is an extremely rare tumor of the orbit. We report 4 cases of primary orbital liposarcoma treated at our center. All cases had tumor localized to the orbit and underwent exenteration followed by radiotherapy in one patient. None of the patients had a recurrence until a follow-up of 1-5 years (mean: 4 years).
