Case report of penile Rhizopus arrhizus infection in an unexpected patient

There are few reports of penile mucormycosis and even fewer in the absence of overt immune suppression. An eighty year old male with diabetes presents with penile mass. The pathology and culture demonstrated Rhizopus arrhizus. He was treated with surgery and liposomal amphotericin B. His therapy was stopped after pathology demonstrated clear surgical margins. His good outcome provides evidence that stopping antifungal therapy after achieving clear surgical margins is acceptable in patients without ongoing immunosuppression.
