Area of Science:

Ophthalmology
Oncology
Pathology

Background:

Primary dedifferentiated liposarcoma of the orbit is an exceptionally rare clinical entity.
Orbital tumors can present with varied symptoms, necessitating comprehensive diagnostic approaches.

Observation:

A 41-year-old male presented with a two-month history of right eye pain, pain with eye movement, and proptosis.
Neuroimaging identified a mass superior to the right superior rectus muscle.

Findings:

Surgical resection via right frontal craniotomy was performed.
Histopathological examination confirmed the orbital mass as dedifferentiated liposarcoma.

Implications:

Primary orbital dedifferentiated liposarcomas pose diagnostic and therapeutic challenges.
Ophthalmologists and oncologists should consider liposarcoma in the differential diagnosis of orbital masses.
