Abstract
PURPOSE: The authors examined the prevalence of a histologic change of ocular adnexal lymphoma (OAL) grade in patients with a history of lymphoma in nonocular sites. METHODS: In this retrospective study, the authors reviewed the clinical and pathological data of 209 patients with OAL treated by the senior author during 2000 to 2017. RESULTS: Of 209 patients with OAL, 65 (31%) had a history of lymphoma. In 54 of the 65 patients (83%), the original lymphoma and OAL were of the same histologic type. In 8 of the 65 patients (12.3%), the OAL was more indolent than the original lymphoma: 6 patients with a history of diffuse large B-cell lymphoma, one of mantle cell lymphoma, and one of grade 3 follicular lymphoma had biopsy-proven extranodal marginal-zone lymphoma in the orbital area. Two additional patients (3%) with a history of chronic lymphocytic leukemia developed OAL: diffuse large B-cell lymphoma in one patient and extranodal marginal-zone lymphoma in the other. One patient (1.5%) with a history of a low-grade follicular lymphoma relapsed as a different low-grade histology of extranodal marginal-zone lymphoma. Lower-grade OAL than the original lymphoma was more common than higher-grade OAL than the original lymphoma (p = 0.048). CONCLUSIONS: In this cohort of 209 patients with OAL, the authors found that nearly one third had a history of lymphoma, 17% of whom had a different histologic type of lymphoma in the orbit, more commonly a more indolent type. This underscores the importance of biopsy of OAL even in patients with a known history of lymphoma to determine the histologic subtype of orbital lymphoma and to help guide appropriate treatment.
