["Metastatic" Crohn's disease of the penis].

Inflammatory genital cutaneous involvement of Crohn's disease is a rare complication. In a 23 year old man, who had colonic Crohn's disease treated by colectomy 3 years earlier, a phimosis revealed a penile localisation of Crohn's disease. "Metastatic" locations of Crohn's disease are defined by granulomas sitting at a distance from the injured bowel. Their clinical manifestations are misleading and their course is independent of the digestive disease. In our patient, after failure of classical therapy, cyclosporin A permitted a slow regression.
