| Sumario: | BACKGROUND: Pyoderma gangrenosum (PG) is a rare ulcerative skin disease; its etiology is unknown, though it is often associated with autoimmune diseases. Pyoderma gangrenosum results in significant morbidity and exquisite pain that affects health-related quality of life. Wound healing is delayed, and patients often experience relapse. Pyoderma gangrenosum is susceptible to pathergy and deterioration with surgical intervention or other trauma; therefore, treatment includes atraumatic wound care, infection management, and local or systemic immunosuppression. CASE: We describe the use of modified negative pressure wound therapy (NPWT) with intralesional and topical steroids for the treatment of PG in a 15-year-old female patient with ulcerative colitis and a staged J-pouch ileoanal reconstruction. The patient and her family refused all systemic therapy due to prior steroid-associated weight gain. She was unable to tolerate conscious dressing changes, further complicating the treatment plan. Procedural interventions such as NPWT have been used previously for PG; however, they can cause wound pathergy and subsequent wound deterioration. Modified NPWT in conjunction with topical and intralesional steroids induced wound healing without producing pathergy. CONCLUSION: Timely recognition of PG is crucial to appropriate delivery of care. Modified NPWT and localized corticosteroid treatment were key to promoting wound healing in this case of pediatric PG.
