Case report demonstrates orbital Richter transformation and subsequent MALT-type lymphoma in chronic lymphocytic leukemia, highlighting diverse ocular lymphoproliferative presentations.
A 74-year-old man with a history of chronic lymphocytic leukemia (CLL) presented with large salmon-colored patch lesions along the inferior fornix and superotemporal conjunctiva of the OS. The patient underwent an incisional biopsy of the lesions, which showed a CLL with areas of large B-cell lymphoma, consistent with Richter transformation. Following medical and radiation-based therapy of these lesions, the patient returned 3 months later with inferomedial preseptal swelling in the contralateral eye, which biopsy proved to be recurrent/resistant low-grade CLL with a posttreatment extranodal marginal zone B-cell lymphoma pattern. This case exemplifies a rare presentation of CLL with Richter transformation and a recurrent/resistant posttreatment orbital CLL with a marginal zone B-cell lymphoma-like pattern.
