Intraocular Metastasis of Large T-cell Lymphoma Transformed from Mycosis Fungoides.

To describe a rare case of intraocular lymphoma that metastasized from cutaneous mycosis fungoides and transformed to large cell T cell lymphoma resulting in vitreoretinal pathology. Retrospective case report. A 57-year-old male presented with 3 months of blurred vision in the right eye. He reported only a medical history of psoriasis. Examination revealed keratic precipitates and dense vitritis in the right eye. He was taken for a diagnostic vitrectomy. Histopathology showed that atypical lymphoid cells and flow cytometry were consistent with transformed large cell T-cell lymphoma. During follow-up, pre- and inner retinal lesions were noted throughout the posterior pole. Histopathology of the psoriatic lesions was consistent with mycosis fungoides. He was initiated on systemic and intravitreal methotrexate with improvement in vision. Ocular involvement in metastatic transformed T-cell lymphoma is extremely rare but can be present with vitritis and retinal deposits. Our patient responded well to intravitreal methotrexate therapy.
