Primary Conjunctival Malignant Lymphoma of Mucosa-Associated Lymophoid Tissue

ABSTRACT

Malignant lymphomas arising in mucosa-associated lymphoid tissue(MALT) account for a significant proportion of extranodal lymphomas. Included among this group of tumors are lymphomas of the gastrointestinal tract, salivary gland, lung and thyroid. But their conjunctival involvements are rare, less than 1.5% of all conjunctival tumors. The authors examined the 51-year-old man who showed the primary conjunctival malignant lymphoma of MALT. It involved the inferior fornix and medial canthal area in his left eye without systemic involvement. We confirmed it by immunohistochemical studies of biopsied tissue, also including computed tomography, sonography, thyroid and bone scan. The patient was successfully treated with radiotherapy. We report this case with a recent review of the ophthalmic literature.
