We have discussed symptoms of dysmorphophobia and mechanism by which it is produced on the basis of our experience in 10 cases with dymorphophobia as chief complaint. Studies were made on a group of five patients who complained of only dysmorphophobia in a mono-symptomatic way and a group of five patients who had a disease coming under the purview of schizophrenia with complaints of dysmorphophobia as a symptom of thct disease. Dysmorphophobia in the former group was dulusion as a menifestation of avoidance, and cases belonging to this group are considered to be a type of anthrophobia, and they are also characterized by being complocated with a fear of emitting bad odors. Patients with this type of anthro phobia are composed mostly of men in adolecence, which is interesting in comparison with the fact that anorexia nervosa is often found in women.
