Objective: To describe patterns, comorbidity, and outcomes from a case series of anorexia nervosa (AN) among young men from the general population and their co‐twins. Method: Men ( N = 2,122) born between 1975 and 1979 from Finnish twin cohorts were screened for lifetime eating disorders by questionnaire. The administration of the short version of the Structured Clinical Interview for DSM‐IV for screen positives led to a lifetime AN diagnosis in five participants, described here with their co‐twins. Results: In males, overweight commonly predated AN, and symptoms of body dysmorphic disorder, particularly of muscle dysmorphia, were common among the anorexia‐discordant co‐twins. Affective and anxiety disorders were present in both the probands and their co‐twins. Conclusion: We found a strong familial clustering of AN, affective and anxiety disorders, and symptoms of muscle dysmorphia among men in the general population. In men, muscle dysmorphia may represent an alternative phenotype of AN. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2008
