Pyoderma Gangrenosum after Breast Mammoplasty Sur-gery: A Case Report

Pyoderma gangrenosum (PG) is a rare inflammatory neutrophilic dermatosis, characterized by painful ulcerative, bullous, or pustular skin conditions. Pathergy is usually used to describe PG which refers to initiation or exacerbation of the disease after accidental or iatrogenic skin trauma. Diagnosis of postoperative PG is challenging not only due to its presentation mimics infectious wounds, but also because there are no standard laboratory parameters for diagnosis. Herein, we present a case of a 46-year-old female patient who had recurrent bilateral breast wound erythema, swelling, pain and necrosis after breast reduction mammoplasty at Centro Hospitalar Conde São Januário Macau SAR in 2018. We diagnosed her postoperative PG and successfully treated her with oral prednisolone with significant therapy response.
