Spectral-domain optical coherence tomography of conjunctival mucosa-associated lymphoid tissue lymphoma with presumed choroidal involvement

Abstract

BackgroundConjunctival mucosa-associated lymphoid tissue (MALT) lymphoma has been well-described, but rarely do these lesions demonstrate intraocular involvement. We report a case of conjunctival MALT lymphoma with intraocular involvement and novel spectral-domain ocular coherence tomography (SD-OCT) findings.Patient and methodsA 75-year-old woman with biopsy-proven MALT lymphoma of the conjunctiva presented with ipsilateral yellowish diffuse choroidal infiltrates on fundoscopic examination. Choroidal involvement was documented clinically, on ultrasonography, on fluorescein angiography, and by SD-OCT. Treatment consisted of 3 weeks of oral doxycycline and six cycles of systemic chemotherapy with cyclophosphamide, vincristine, prednisone, and rituximab.ResultsThere was no evidence of progression or recurrence of MALT lymphoma after 9 months of follow-up. Despite complete resolution of clinical findings, ultrasound, and fluorescein angiography, the choroidal lesions remained unchanged on SD-OCT.DiscussionChoroidal involvement of conjunctival MALT is rare, and can be successfully treated. Persistence of irregularities on SD-OCT did not influence management in the presence of clinical improvement and resolution on ultrasonography and fluorescein angiography.
