Intersection of Diabetic Foot Infection and Pyoderma Gangrenosum: A Conflicting Treatment Approach.

A 67-year-old man with long-standing diabetes presented with a nonhealing diabetic foot infection that was complicated by the emergence of pyoderma gangrenosum.

• The patient initially prompted antibiotic treatment and surgical debridement for the diabetic foot infection.
• The coexistence of DFI and PG created a conflict in treatment approach, as treating one condition may exacerbate the other.
• This represents a case report of a single patient.

The patient responded positively to systemic corticosteroids and infliximab as treatment for pyoderma gangrenosum.

• Systemic corticosteroids and infliximab were the immunosuppressive agents used in this case.
• The response to these treatments was described as positive.
• Immunosuppressive therapy for PG conflicts with the management of an active diabetic foot infection, as suppressing the immune response may worsen infection control.

Surgical debridement proved necessary in this patient despite conflicting recommendations regarding its use in pyoderma gangrenosum.

• Surgical debridement is a standard treatment for diabetic foot infection but is generally contraindicated or approached cautiously in pyoderma gangrenosum due to the risk of pathergy.
• Despite these conflicting recommendations, surgical intervention was ultimately required in this case.
• The authors stress the need for ongoing research regarding surgical debridement in these complex scenarios.

The authors advocate for early pyoderma gangrenosum diagnosis using the Delphi model in cases of complex diabetic foot wounds.

• The Delphi model is identified as a diagnostic tool recommended for early PG diagnosis.
• Early diagnosis is emphasized as important given the conflicting treatment approaches required for DFI and PG.
• The report stresses the need for ongoing research regarding surgical debridement in these complex scenarios.
