Recurrence of Metastatic Crohn's Disease after Surgical Resection.

A 36-year-old woman presented to the emergency department with a 1-day history of purulent perianal and vulvar discharge. She had a 25-year history of Crohn's disease (CD), and 13 years prior had received a total colectomy with end ileostomy. She had vulvar biopsies 5 years prior to presentation, demonstrating noncaseating granulomas consistent with metastatic Crohn's disease (MCD). Throughout the course of her disease, she had a failed treatment with adalimumab, certolizumab, methotrexate, and 6-mercaptopurine. She had received a radical vulvectomy 1 year prior to presenting to control recurrent vulvar abscesses and MCD while receiving monthly subcutaneous infliximab 10 mg/kg body weight. Dermatology was consulted at presentation, and the physical examination revealed tender, linear ulcerations with a granulated appearance and depigmentation on the natal cleft and vulva (Figures 1 and 2). Computerized tomography (CT) scan of the abdomen and pelvis indicated thickening of soft tissue without evidence of abscesses, fluid collection, or fistulae. Given the distribution and morphology of lesions with a history of biopsy-proven MCD, the patient was diagnosed with a flare of MCD.
