title: Crohn's disease of the vulva.
abstract: Three patients with Crohn's disease primarily involving the large intestine had unusual abscesses of the vulvar area. At biopsy, the abscesses had classic features of the primary disease and were clearly separated from the intestinal tract. There was no fistula in the anal canal, and the perineum between the vulvar abscess and the anus was normal. One of the patients also had an early lesion of Crohn's disease in the sigmoid. The lesion appeared as a small erythematous spot without ulceration. Biopsy revealed a typical granuloma under an intact mucosa. It is concluded that Crohn's disease is not confined to the gastrointestinal tract, and that early lesions of the disease within the gastrointestinal tract are submucosal rather than mucosal.
