I've heard of body dysmorphic disorder, where people who are anorexics see themselves as much larger than they really are. But it turns out, it's not just that. Anorexics couldn't sketch a simple object they had felt but not seen. They couldn't approximate the shape of the object while blindfolded. They couldn't estimate the size of an object using calipers. Apparently, their right parietal cortex, which helps to integrate the various senses was active, but not able to adequately process the information coming from the hand they couldn't see, according to this article.

This cries out for a real study.
