    TLDR Bullous pyoderma gangrenosum can develop on cesarean scars and may require steroids for treatment.
    A 34-year-old woman developed bullous pyoderma gangrenosum (PG) on her cesarean section scar postpartum, characterized by bullous lesions, fever, and elevated C-reactive protein levels. Despite initial antibiotic treatment, her condition improved rapidly with oral prednisolone. This case is notable as the first reported instance of bullous PG on a cesarean scar, highlighting the potential overlap between PG and bullous Sweet's syndrome. The study suggests that immune system changes during pregnancy and surgical triggers may predispose certain patients to PG.
