AbstractBACKGROUND AND OBJECTIVE: Localized orbital non Hodgkin's lymphoma is a rare event which has not been reported much in the literature. The aim of this study was to evaluate the clinical features, histology, treatment and clinical outcome of patients with localized orbital lymphoma. METHODS AND RESULTS: Fifteen patients with stage I-E orbital lymphoma diagnosed between 1975 and 1992 were reviewed. Diagnosis was formulated from 3-84 (median 23) months after the appearance of symptoms. Eight patients were males and 7 were females; median age was 55 years. The lacrimal gland was involved in 8 cases, the orbit in 7. Bilateral orbital localization was observed in only one patient. All cases were diagnosed as low-grade MALT lymphoma. Chemotherapy was administered in 7 patients, radiotherapy was employed in 7 and surgical excision was performed in the remaining case. Almost all the patients (14/15; 93%) achieved a complete remission (CR). Local relapse (LR) was observed in 3 cases but disease spread was never recorded. INTERPRETATION AND CONCLUSIONS: Correct histological diagnosis and careful staging are very important for the treatment and outcome of localized low-grade orbital lymphoma. These patients show a very good prognosis and radiation therapy alone is very effective in the treatment of this malignancy.
