摘　　要：Parastomal pyoderma gangrenosum(PPG)is an unusual neutrophilic dermatosis characterized by painful,necrotic ulcerations occurring in the area surrounding an abdominal stoma.It typically affects young to middle-aged adults,with a slight female predominance.The underlying etiology for PPG remains enigmatic but aberrant immune response to injury may play a pivotal role.The reported risk factors for the development of PPG include the presence of extra-intestinal manifestations,autoimmune disorders and obesity,along with local factors,such as the presence of parastomal hernia or pressure ulcer.PPG can develop at any time after the stoma construction.The histopathological features of PPG are not pathognomonic and its diagnosis is mainly based on clinical features.The management of PPG often requires a multidisciplinary approach,with a combination of local wound care and systemic medications.
