Clinical analysis of 94 cases of ocular adnexal lymphomas

Abstract

To investigate the imaging manifestations and pathological features of ocular adnexal lymphoma (OALs) in order to provide relevant information for ophthalmologists. A total of 94 patients with OALs were pathologically confirmed between August 2018 and July 2023, and their demographics, location, subtype, treatment, and prognosis were retrospectively studied. 94 patients with OALs were included in this study, of whom 28 were female (29.79%) and 66 were male (70.21%). The age of the patients ranged from 21 to 80 years, with a predominance of 50–60 years (60/94); monocular onset was common (90/94), and the most site of onset was orbital (74/94), followed by conjunctiva (12/94), eyelids (4/94), vitreous (3/94), and lacrimal gland (1/94). CT and MRI can show the involvement and extent of the lesions, and the pathology of the disease is characterized by mucosa‐associated lymphoid tissue marginal zone B‐cell lymphoma (72/94), diffuse large B‐cell lymphoma (10/94), T‐cell lymphoma (4/94), mantle cell lymphoma (2/94), Burkitt's lymphoma (2/94), small lymphocytic lymphoma (2/94), and follicular lymphoma (1/94). All patients received surgical treatment, 42 patients received local radiation therapy, 35 patients received chemotherapy, 13 patients received radiation therapy and chemotherapy successively, and 3 patients received comprehensive treatment. During the follow‐up, three patients relapsed, four died, one was lost to follow‐up, and the remaining patients had stable conditions. The majority of OALs are mucosa‐associated lymphoid tissue marginal zone B‐cell lymphomas (MALT) with an excellent prognosis. It mostly occurs in people over 50 years of age and most site of the onset is orbital.
