Primary small B cell non-Hodgkin Lymphoma of the Lacrimal Sac Upon Chronic Dacryocystitis

Abstract

Primary non-Hodgkin lymphoma of the lacrimal sac is an extremely rare tumor. In this article, we report a 44-year-old female who was referred for dacryocystorhinostomy with complaints of epiphora and swelling on the right lacrimal sac region. She had slight epiphora for 8 years, which increased within 6 months, with concomitant swelling between the eye and the nose. A hard and fixed mass was detected on palpation just below the medial canthus. Magnetic resonance imaging showed a 30x35 mm tumoral, lesion which invaded the medial wall of the right orbit and compressed the medial rectus muscle. Histopathologic examination of the tumor revealed a small B cell non-Hodgkin lymphoma. As a conclusion, we suggest that if symptoms of a chronic dacryocystitis patient deteriorates, malignancy should be suspected
