Pyoderma gangrenosum and dehydrated human amnion/chorion membrane: a potential tool for an orphan disease.

This retrospective pilot case series examined the use of DHACM as an alternative wound treatment for PG patients failing standard therapies. DHACM treatments re-initiated the trajectory towards wound closure for each stalled PG ulcer. The results suggest a treatment algorithm starting with early recognition, wound closure via treatment escalation, and lastly a gradual reduction in treatment for durable closure. DHACM treatment should be formally evaluated as an adjunct to PG ulcers that have remained refractory to more commonly used immunomodulating therapies.
