Rhino sinusitis caused by Lasiodiplodia theobromae in a diabetic patient

Abstract

We report an uncommon instance of rhinosinusitis by Lasiodiplodia theobromae in a known diabetic patient. A melanized fungus called Lasiodiplodia theobromae causes a typical plant disease that rots fruits and plants. Infections in humans are currently limited. Mostly from tropical and subtropical regions, there have been few reported occurrences. The fungus has been associated with clinical manifestations such as onychomycosis, corneal ulcers, and phaeohyphomycosis. Identification by phenotype was inconclusive. DNA sequencing was used for final identification. Amphotericin B and surgical debridement were effective treatments for the patient.
