They are scent glands and they do look normal to me. Do you have any other hamsters especially females? If they smell others they can scent more to let them know they are there. The fur gets quite wet and greasy to spread the scent. Another thing that makes them scent is over cleaning of the cage. They don't like too much cleaning and it does stress them when they lose their smell around them. They overcompensate by rubbing around and licking the scent then rubbing it over things. Keep it to a minimum and only do spot cleans in wet corner. Poops are dry and harmless. Don't do full cage cleans and always replace some of the scented bedding back in the cage to try and help them settle after a clean.
