[Mycotic dacryocystitis related to naso-lacrimal stent.  Case report]. 
A nasolacrimal stent was placed in a diabetic woman with a ten-year history of epiphora.  Three months later the non-functional stent was removed and taken for histological study.  A presumed diagnosis of fungical dacryocystitis was then established.  An external dacryocystorhinostomy was performed and the obtained cultures confirmed Candida albicans as the infective agent.  Only 1.2% of all dacryocystitis are due to fungal agents.  This possibility must be considered when evaluating a routine chronic dacryocystitis.  Cultures should be obtained when removing a nasolacrimal stent in order to rule out different causes of nasolacrymal obstruction.
