Ocular adnexal lymphoid tumors.

This year, advances in the management of ocular adnexal lymphoid tumors have been based on the distinction between MALT and non-MALT lymphomas. MALT lymphomas have a more indolent course than non-MALT lymphomas, and in the conjunctiva a more conservative approach can be taken than has been recommended previously. In the orbit the likelihood of progression to systemic disease seems high, even with MALT lymphomas, and treatment with radiation is still recommended in all cases. The REAL classification system has replaced the Rappaport and Lukes-Collins system for classifying ocular adnexal lymphomas. Most ocular adnexal lymphomas are composed of neoplastic B-lymphocytes. Additional cases of T-cell lymphoma involving the orbit and conjunctiva were reported in the literature this past year.
