Supplemental material, clinical images: Establishment of standardized definitions and a core set of outcome characteristics following hidradenitis suppurativa surgery developed by an expert Delphi consensus

A. Immediately following partial regional excision affected tissue is present at the surgical margin (A1) and, as expected, surgical site persistence is noted 4 weeks later while the wound is still healing (A2). B. Three weeks after complete regional excision there is no disease in the region (B1), but 6 months post-operatively a new nodule has presented inferior to the scar consistent with regional progression (B2), which self-resolved 2 weeks later. C. One year following intermammary complete regional excision, no disease is present (C1), but six months following that time a new nodule arose at the surgical margin consistent with surgical site progression (C2), which required a localized surgical intervention.
