Lymphoma involving the lacrimal gland is rare. Most of the cases are unilateral at presentation. In this case, we present the diagnostic evaluation of a patient with bilateral lacrimal gland lymphoma. At presentation, the patient had inferomedial excentric proptosis of the right eye. The patient also had limitation in the upper and lateral gas in this eye. On magnetic resonance imaging, a mass was detected not only in the right but also in the left eye corresponding to the area of the lacrimal gland. Excisional biopsy was performed in the right eye with lateral orbitotomy approach. Histopathological examination revealed the extranodal marginal zone lymphoma involving the lacrimal gland. No concurrent systemic lymphoma was detected during the systemic evaluation of the patient. The patient was directed to the oncology department for systemic treatment planning. In conclusion, bilateral involvement is rare in lacrimal gland diseases but it can show severe diseases like lymphoma.
