Primary Canalicular MALT Lymphoma Masquerading as Chronic Canaliculitis

Abstract

A 67-year-old female presented with chronic canaliculitis and underwent canalicular marsupialization. During the procedure, a fleshy mass was found in the canaliculus, which was excised completely and sent to pathology. Histology confirmed the diagnosis of extranodal marginal zone mucosa-associated lymphoid tissue lymphoma. The patient underwent staging with positron emission tomography/CT scan, which did not show any hypermetabolic foci elsewhere in the body, so the patient elected to undergo close observation without further treatment. At 12 months of follow-up, the patient has remained disease-free.
