Aim:
To report the abnormal type of the orbital liposarcoma-dedifferentiated subtype in a patient.

A case report.

Magnetic resonance imaging scanning showed an irregular shaped tumor in the right orbit. The tumor resection was done with a clinical diagnosis of malignant tumor. Histopathological findings revealed the diagnosis of dedifferentiated liposarcoma.
Conclusion:
The rare occurrence of this tumour should be kept in mind while dealing with orbital tumours.
