Liposarcoma is extremely rare malignant tumor which develops primary in the orbit. Here, we report a case of primary orbital liposarcoma in 17 year old female patient. She visited our hospital due to decreased visual acuity and protrusion of Rt. eyeball. Malignant tumor was suspected by many examination. So exenteration was performed and tumor mass was confirmed as liposarcoma by pathologic examination. She was received cobalt 60 radiation therapy, but recurrent tumor mass appeared at the orbital apex 1 year after operation.
