[Crohn's disease with isolated vulvar localization and pregnancy. A case report].

Extra-intestinal manifestations of Crohn's disease are well described. A very uncommon gynaecologic manifestation of this disease is vulvar involvement. Till now, sixteen cases have been reported in the literature. We report a case of a pregnant woman with isolated vulvar involvement, without bowel manifestations. The diagnosis have been clinically uncertain, but the histopathology goes with Crohn's disease. Discussion point out the difficulties in diagnosis and management of this vulvar condition, and of its association with pregnancy.
