Non-Candida albicans Candida mediastinitis of odontogenic origin in a diabetic patient.

Descending mediastinitis occurs as a complication of oropharyngeal or cervical infections and its delayed diagnosis and treatment are associated with high mortality. A rare case of an odontogenic infection in a diabetic patient, complicated by Candida parapsilosis and Candida krusei parapharyngeal space infection, descending mediastinitis and aspiration pneumonia is described. Isolate identification was based on colonial and microscopic morphological characteristics and carbohydrate assimilation test results. The patient was successfully treated with surgical drainage and debridement, broad spectrum antibacterials and liposomal amphotericin B followed by prolonged oral voriconazole therapy.
