Spontaneous Regression of High-Grade B-Cell Lymphoma With MYC and BCL2 Rearrangements: Case Report and Literature Review

Spontaneous regression of secondary vitreoretinal lymphoma after diagnostic vitrectomy: case report

PURPOSE

Our purpose is to report a patient with secondary intraocular mucosa-associated lymphoid tissue (MALT) who experienced spontaneous regression after diagnostic vitrectomy.

METHODS

We retrospectively reviewed the clinical and imaging features of the case. Multimodal imaging, including fundus photograph, optical coherence tomography, fundus fluorescein angiography and ultrasound scan was presented.

RESULTS

A 71-year-old female presented with a subretinal lesion temporal to macula and scattered multifocal creamy lesions deep to retina in her left eye. Optical coherence tomography of the left eye showed multifocal nodular hyper-reflective signals between the Bruch's membrane and RPE. She had a history of gastric MALT lymphoma. Diagnostic vitrectomy was performed. IL-10 level of aqueous was 187.7pg/ml. Cytology, gene rearrangement and flow cytometry of the vitreous were inconclusive. Systemic evaluation was normal. Secondary vitreoretinal MALT lymphoma was considered. Interestingly, her subretinal lesions regressed gradually without any chemotherapy. And IL-10 level of aqueous declined to 64.3pg/ml.

CONCLUSIONS

Secondary vitreoretinal MALT lymphoma is extremely rare. Spontaneous regression of intraocular lymphoma does occur.

Secondary vitreoretinal lymphoma with spontaneous regression

Purpose

To report a patient with vitreoretinal lymphoma (VRL) secondary to systemic diffuse large B-cell lymphoma, who had two episodes of spontaneous regression.

Observations

An 80-year-old Nicaraguan male with a history of treated systemic diffuse large B-cell lymphoma presented with decreased vision in his right eye over one year. The patient was found to have subretinal lesions and moderate vitreous opacities in his right eye. Cytological analysis of vitreous confirmed B-cell lymphoma. Following his systemic work-up, spontaneous clinical improvement was noted. There were no vitreoretinal or systemic lymphoma recurrences during one year of follow-up until the patient had new onset decreased vision in the left eye. He was presumed to have a recurrence of VRL supported by optical coherence tomography findings. Repeat systemic workup was negative for reoccurrence and the ocular lesions resolved spontaneously over 4 weeks.

Conclusions

Spontaneous regression of intraocular lymphoma can rarely occur. Multimodal imaging has an essential role in diagnosing and monitoring recurrence of this disease.
