A case of primary conjunctival follicular lymphoma presenting as nasolacrimal obstruction.

We herein report a 76-year-old male who presented to the ophthalmology clinic after complaining from excessive lacrimation for ~6 months prior to presentation. He reports previously undergoing a nasolacrimal recanalization procedure in attempts to resolve his symptoms, but reported no improvement. On examination, a mass on the nasal conjunctiva around the medial canthus of the right eye was noted and subsequently excised. The findings support the diagnosis of low-grade follicular lymphoma. The patient was referred to radiation oncology for radiation therapy and received a total dose of 2400 cGy. Most ocular adnexal lymphomas are B-cell in origin, with follicular lymphomas being one of the rarest forms of such lymphomas. The most common translocation reported in over 85% of follicular lymphomas of the ocular adnexa is t(14; 18) (q32; q21). Traditional treatment options typically include a mix of chemical, surgical, and radio-oncological interventions.
