title: Diagnosis of anorexia nervosa in the adolescent male.
abstract: Sporadic cases of anorexia nervosa in the male patient have been described. We present three cases of weight loss in adolescent males. The first is a typical case of primary anorexia nervosa. The second illustrates weight loss in the competitive adolescent athlete. The third was mistakenly thought to have primary anorexia nervosa. At autopsy, he had regional enteritis. These patients are compared to call attention to the differential diagnosis of anorexia nervosa in the adolescent male.
