Abstract
Mucormycosis is an acute fungal infection in humans that is often fulminant and potentially fatal. It occurs most frequently in immunocompromised individuals. We report a diabetic patient who presented in ketoacidosis with lacrimal sac infection from this organism. To the best of our knowledge, this is only the second patient with dacryocystitis caused by this fungus described in the medical literature. Our patient is unique in that she had no evidence of concurrent sinus involvement. Surgical debridement and antifungal therapy were combined to ensure a successful outcome.
