EtiopathogenesisThis section has been translated automatically.
Unclear, possible infection with streptococci ( Erysipelas gangraenosum genitalium, Erysipelas genitalium), fusiform bacteria, spirochetes etc. Possibly Sanarelli-Shwartzman phenomenon. Predisposing factors discussed are previous surgery or trauma (e.g. also after dental piercing: Ekelius L et al. 2004) and systemic diseases (e.g. diabetes mellitus).
In summer 2018 the FDA has included Fournier gangrene as a rare side effect in the technical information of SGLT2 inhibitors. A connection with therapeutically intended glucosuria is suspected.

Internal therapyThis section has been translated automatically.
- High-dose parenteral therapy with broad-spectrum antibiotics such as ampicillin (e.g. Binotal). Adults: 150-200 mg/kg bw/day, children > 1st year of life 100-400 mg/kg bw/day distributed on 4 ED, infants < 1st week of life 50-150 mg/kg bw/day distributed on 2-3 ED, infants > 1st week of life 100-300 mg/kg bw/day distributed on 3-4 ED.
- Alternative: benzylpenicillin (e.g. penicillin Grünenthal), adults: 6 times 4 million IU/day, children > 1 year of age: 50,000-250,000 IU/kg bw/day divided into 4-6 days, infants < 1 week of life: 50,000-250,000 IU/kg bw/day divided into 2 days, infants > 1 week of life 75,000-350,000 IU/kg bw/day divided into 4 days.
- Alternative: gentamicin (e.g. refobacin) Adults: 3-5 mg/kg bw/day divided into 1-3 doses, children > 1st year of life: 5-7 mg/kg bw/day divided into 3-4 doses, infants < 1st week of life: 5 mg/kg bw/day divided into 2 doses, infants > 1st week of life: 7.5 mg/kg bw/day divided into 3 doses combined.
- For penicillin resistance: 3rd generation cephalosporins, e.g. cefotaxime (claforan) 3 times/day 2 g i.v.
- In case of resistance to therapy: combination of a cephalosporin with an aminoglycoside, e.g. rocephin 2 g/day i.v. with refobacin 1 time/day 240 mg i.v. or combination of vancomycin (e.g. Vanco-Cell) 2 time/day 1 g i.v. with gentamicin (see above).
