The majority of ocular adnexal lymphomas are B-cell in origin. We report two cases of T-cell lymphoblastic lymphoma (T-LBL) involving the ocular adnexa. One patient presented with a painless pink conjunctival lesion and inferior orbital fullness. The second patient presented with a painless orbital mass. The diagnoses were confirmed by histopathology and immunohistochemistry. Both patients had extensive multifocal lesions during staging. Prompt intensified chemotherapy regimens were initiated. T-LBL is an aggressive disease with poor prognosis. This report emphasizes the importance of timely diagnosis by the ophthalmologist with co-management and treatment with an oncologist.
