Results There was not specificity of clinical symptoms in liposarcoma of the orbit, the major clinical aspects were intraorbital occupied lesion and local hyperaemia,swell and pain which was similar to an acute inflammation. Four different subtypes of liposarcomas could be observed in orbit.In past literature,myxoid was the most common subtype（14 cases,70%）,secondly subtype was well differentiated（3 case）,round cell and pleomorphic subtype were rare（each 1 case）.This case was well differentiated mixed component of round and pleomorphic lipoblasts.
