Bilateral primary orbital lymphoma with proptosis: A case report.

Primary orbital lymphoma is a rare extranodal type of lymphoma. Although lymphomas of the head and neck are uncommon, it is the most common orbital malignancy. Most common type is Non-Hodgkin diffuse large B-cell lymphoma. Clinical manifestations can vary, including gradual progressive proptosis, restricted ocular movement, decreased visual acuity, periorbital edema, and diplopia. We describe a case of bilateral primary orbital lymphoma which presented as fever and weight loss for 3 months with history of bilateral proptosis and eye discharge for 2 months. Clinical examination and radiological imaging were consistent with primary orbital lymphoma and was confirmed on histopathological analysis. Treatment is multidisciplinary and includes surgery, radiotherapy, and chemotherapy.
