Primary Marginal Zone B-Cell Lymphoma of the Mucosa-Associated Lymphoid Tissue of the Lacrimal Sac Found with Epiphora: A Case Report

Abstract

We report a case of a primary marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue of the lacrimal sac, which was found in a patient with epiphora without palpable mass. Magnetic resonance imaging demonstrated mucosal thickening of the lacrimal sac with a patent lumen, consistent with the intraoperative finding. Epiphora resolved, which was confirmed by smooth syringing, 1 month after starting the immunotherapy.
