! am a 48 year old male with a diagnosis of ulcerative colitis. I have this condition since i was 22years old. My medication was changed fro pentasa almost 5 years ago to mercaptopurine 50mg once daily. Since commencing this medication i have notice a recurring itch under the foreskin with red blotches and unpleasant smell. On occasions there is a build up of a wax type subtance. I am concerned about this condition which i have had for almost 3 years now. I have suspected candida balicans, however i am uncertain.
