Primary bilateral and symmetric MALT lymphoma of the lacrimal sac mimicking chronic dacryocystitis

Linfoma MALT primário, bilateral e simétrico do saco lacrimal simulando dacriocistite crônica

Abstract

We report a case of primary bilateral mucosa associated lymphoid tissue (MALT) lymphoma of the lacrimal sac. MALT lymphoma is a subtype of Non-Hodgkin's Lymphoma of the ocular adnexa. When the primary site of the lymphoma is the lacrimal sac, it mimics chronic dacryocystitis. This may delay diagnosis, with potentially lethal results.
