Peristomal Pyoderma Gangrenosum in a Rectal Cancer Patient With an Ileostomy: A Case Study.

Background: Peristomal pyoderma gangrenosum (PPG) is a rare complication mainly associated with inflammatory bowel disease. Although it has also been found in patients with an ileostomy with rectal cancer, the best treatment options in this context have not been precisely elucidated.

Case: This case report describes the importance of a multidisciplinary treatment approach for a rare case of PPG around a protective ileostomy resulting from rectal cancer.

Conclusions: Early diagnosis of PPG is imperative to avoid further extension of the lesion. Aggressive management with a multidrug treatment, both topical and systemic, is recommended in severe cases. Close monitoring of the response is necessary, given the variability in the effectiveness of the treatments.
