What is your approach to managing pyoderma gangrenosum recalcitrant to oral steroids?
Pyoderma gangrenosum is notoriously difficult to treat. The first thing I'd recommend in a case refractory to steroids is to reconsider the diagnosis. Notably, a high percentage of PG is misdiagnosed, so lack of response may indicate that you are dealing with a mimicker (e.g., infection, neoplasm, v...
PG is a symptom of an underlying diagnosis. Investigation needs to be undertaken to determine if they have GPA, IBD, etc, and then treat that diagnosis. Right now steroids are likely masking the diagnosis.
Once diagnosis is confirmed and appropriate workup with multidisciplinary management is begun my go-to for steroid sparing is TNFi (infliximab best but adalimumab good too). Cyclosporine is nice for early on rapid improvement as a bridge especially if they can’t tolerate steroids. More recently, I’v...
I have been using topical cyclosporine with/without oral steroids with good results.

If it is clinically PG after exclusion of the above and associated comorbidity such as Inflammatory bo...
