title: Chronic dacryocystitis secondary to Stenotrophomonas maltophilia and Staphylococcus aureus mixed infection.
abstract: A 40-year-old woman with a history of recurrent attacks of dacryocystitis for 2 years developed a lacrimal sac abscess. β-Lactam antibiotics, considered the first-line treatment for dacryocystitis, were ineffective. She underwent dacryocystorhinostomy. Cultures from the lacrimal sac demonstrated the presence of Stenotrophomonas maltophilia and methicillin-sensitive Staphylococcus aureus, both of which are sensitive to trimethoprim-sulfamethoxazole. This rare and antibiotic-resistant bacterial species should be considered in atypical cases of dacryocystitis, and appropriate antibiotics should be started immediately.
