Fournier Gangrene in a Patient With Type 2 Diabetes Mellitus Treated With Dapagliflozin: A Case Report

Rare cases of Fournier gangrene (FG) possibly associated with sodium-glucose cotransporter 2 inhibitors have been reported. We present a case of a 66-year-old male patient with type 2 diabetes mellitus on oral metformin, glimepiride, and dapagliflozin therapy. He presented with pain in the perineum and scrotum for 5 days. The clinical finding, computed tomography finding, and laboratory data were matched with FG. Emergency surgical drainage, debridement of necrotic tissue, and diverting loop ileostomy formation were performed by a urologist and a surgeon. The patient had no complications from diabetes before the onset of FG, and serum glucose management was good at the onset of FG. This case shows an FG patient with good glucose management taking dapagliflozin and suggests a possible association between dapagliflozin and FG. Further evaluation and additional research on this relationship are needed.
