RT Journal Article SR Electronic T1 Pyoderma gangrenosum following an unplanned caesarean section: a patient revisited JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e238702 DO 10.1136/bcr-2020-238702 VO 14 IS 2 A1 Waseem Ghumra A1 Adam Gold A1 Richard Michael Azurdia YR 2021 UL http://casereports.bmj.com/content/14/2/e238702.abstract AB A 35-year-old woman was referred urgently to the dermatology department because of significant wound breakdown 3 weeks following an emergency caesarean section. Examination revealed a full thickness, undermined ulcer spanning the width of the patient’s caesarean scar, exposing the patient’s uterus. Clinical appearances were consistent with pyoderma gangrenosum. The patient has a history of complicated pyoderma gangrenosum, having undergone skin grafts 14 years prior, for ulcers on her lower legs. That episode was the subject of a case report, published in the BMJ, in 2007. On this occasion, the patient was treated with oral corticosteroids, and ciclosporin based on its efficacy during her previous episode, which in conjunction with negative pressure wound therapy, resulted in complete re-epithelialisation of her ulcer within 6 months.
