[Vulvar involvement in Crohn disease].

INTRODUCTION

There are many skin manifestations of Crohn's disease including specific lesions occurring late after digestive signs. These manifestations are also termed metastatic and are rarely located on the vulva.

CASE REPORT

We observed a metastatic localization in the vulva of Crohn's disease in a 34-year-old woman with predominantly rectosigmoid disease. The right labia major was greatly enlarged with oedema involving the inguinal cural area. Pustulization and erosive lesions were seen. The course of these lesions was independent of the colonic disease and responded temporarily only to a triple drug combination of metronidazol, prednisolone and minocyclin.

CONCLUSION

This case emphasizes the frequency of colonic or rectal manifestations associated with vulval involvement in Crohn's disease. The metastatic lesions follow a course independent of the digestive disease raising therapeutic problems in this localization.
