The clinical presentation of anorexia nervosa among males is quite rare. This paper examines the personality and developmental issues of anorexia nervosa in adolescent males through a comprehensive review of the literature and a case presentation. In addition, this paper will demonstrate the application of the empirical literature in the development of a conceptual model to identify critical diagnostic and psychotherapeutic issues within the assessment of a clinically rare case, a male adolescent with anorexia nervosa.
