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.
