Abstract:
Postoperative pyoderma gangrenosum and peristomal pyoderma gangrenosum are 2 subtypes of pyoderma gangrenosum. The diagnosis is made as a clinicopathologic correlation when assessing a rapidly progressing ulcer with irregular and undermined borders following a surgical procedure, trauma, or the creation of a stoma. Familiarity with the associated risk factors and distinguishing features of these disorders can facilitate prompt recognition, proper diagnosis, and the initiation of treatment. Management usually involves the use of corticosteroids and steroid-sparing agents as immunomodulators to shift the inflammatory neutrophilic dermatoses to chronic noninflammatory wounds and eventual healing.
