ABSTRACT

Lacrimal drainage system can be obstructed by many reasons. One of the reasons of this obstruction is lacrimal sac tumor. Dacryocystorhinostomy was performed to our patient because of chronic dacryocystitis. During surgery it was noticed that lacrimal sac mucosa was thicker than its usual thickness, and biopsy was taken. Pathologic evaluation of the specimen revealed extranodal marginal zone Bcell lymphoma (MALT lymphoma). There was no evidence of systemic lymphoma, and the patient was treated with 42 Gy irradiation. This case demonstrated that chronic dacryocystitis may be the first sign of lymphoma. This rare condition should be taken into consideration in evaluating patients with chronic dacryocystitis.
