Cellulitis caused by Rhizomucor pusillus in a diabetic patient receiving continuous insulin infusion pump therapy.

We have reported a case of primary cutaneous zygomycosis in a diabetic patient receiving continuous insulin infusion pump therapy. We believe this to be the first reported case of a fungal infection associated with the use of an insulin pump. The infection itself was an unusually mild and chronic zygomycosis, possibly due to a low production rate of proteolytic enzymes by a rare opportunistic human pathogen, Rhizomucor pusillus.
