Abstract
Hidradenitis suppurativa (HS) is an inflammatory disease causing nodules, abscesses, sinus tracts, and scars in fold areas. It significantly impacts patients' quality of life. Surgical treatments are becoming popular in dermatology, with deroofing being a common procedure. However, recurrence rates can be high due to not removing fibrotic areas and scar tissue entirely. Recent efforts have focused on removing these tissues to achieve lower recurrence rates. This case report describes a male patient with HS who underwent a newly defined ultrasonography-guided modified deroofing surgery for HS. The wound-healing process was then accelerated with the application of topical insulin. In this case, we would like to highlight the significance of using ultrasonography before HS surgery, confirm the importance of modified deroofing surgery, and emphasize that insulin can be used as an effective supplementary treatment for ulcer management.
