Orbital lymphoma is a rare cause of primary Non Hodgkin lymphomasand represents a major cause of orbital malignancies, usually arising from extraocular muscles, eyelid, and soft tissue adnexa. Overall it presents as an extraconal tumor featuring a broad spectrum of clinical presentation making the diagnosis sometimes challenging. We report the case of a 65 year old male with no prior medical history presenting with a recent ongoing proptosis. Radiological findings were consistent with an extraconal lesion involving the lateral orbital wall responsible for mass effect on the globe and optic nerve, for which histopathological results showed features of a small lymphocytic lymphoma.
