I read with great interest the article by Guenova et al,1 who showed a biological “proof of concept” with an increase expression of interleukin (IL)-23 in a pyoderma gangrenosum (PG) lesion before initiating ustekinumab therapy successfully. A wide number of local and systemic treatments have been tried for this difficult condition and, in the era of biological agents, new, targeted therapies are promising.2
