Primary orbital liposarcoma.

A 45-year-old-man presented a slightly painful proptosis and diplopia for 7 months. He had been kept elsewhere on oral steroids without evidence of any clinical response over an 8-week period with suspected diagnosis of an inflammatory pseudotumor upon referral to our clinic. An intraoperative biopsy positive for primary liposarcoma was followed by debulking surgery. Exenteration and radiotherapy were performed after pathologic confirmation of this diagnosis. No recurrence has been observed after 2 years of follow-up. We underline the importance of an accurate an early diagnosis in the management of this tumor, delayed in this case because of therapy with steroids.
