Successful multidisciplinary treatment of the rare pathology of vulvar Crohn's disease

A woman in her 50s with a medical history of rheumatoid arthritis (RA) and hypothyroidism presented with 3 months of vaginal pain and swelling. Physical examination showed vulvar oedema and erythema, ulcerations of the inferior vulva that extended to the buttocks and introitus with erythema and superficial erosions. MR pelvis showed a fibroid in the uterus but otherwise was unremarkable. Biopsies of the vagina showed extensive acute and chronic inflammation, necrosis and granulomas without concern for malignancy, which was consistent with a diagnosis of cutaneous Crohn's disease. MR enterography, upper endoscopy and colonoscopy revealed no gastrointestinal manifestations of Crohn's. She was treated initially with corticosteroids and metronidazole as well as vulvectomy and graft placement. Azathioprine was added to her regimen due to lack of response; however, despite 6 weeks of this therapy, the ulcerations did not heal thus infliximab was initiated. After 8 weeks the lesions had completely resolved.
