Anorexia nervosa (AN) rarely develops after the age of 30 years, and rarely occurs in men. We report a case of chronic AN in a 72‐year‐old man, who reported a 20‐year history of extreme low body weight, persistent fears of obesity, and feelings of being fat even at 93 Ib. Also reported were episodes of self‐induced vomiting, laxative abuse, and excessive exercising. Patient's scores on a battery of questionnaires were also consistent with a diagnosis of AN. © 1993 by John Wiley & Sons, Inc.
