• Pyoderma gangrenosum is a rare idiopathic skin condition often associated with other diseases, including Crohn's disease. We believe this is the first report of cases in which pyoderma gangrenosum was identified at the parastomal site in patients with Crohn's disease. Four episodes of the condition occurred in three patients. In these patients, pyoderma gangrenosum first appeared after two to three surgical procedures and between ten months and five years after the initial surgery. The disease course varied from resolution within two months with corticosteroid therapy to resolution only after revision or relocation of the stoma with resection of recurrent disease segments. Parastomal pyoderma gangrenosum at the ileostomy site in patients with Crohn's disease may be more common than previously thought. Optimal treatment has not yet been established, and treatment needs to be tailored for each patient.
