A 45-year-old successful entrepreneur is referred for psychiatric evaluation due to ongoing conflicts with his employees and family. He frequently boasts about his achievements, expects constant praise, and becomes enraged when his authority is questioned or he receives any criticism. He believes he is superior to others and is entitled to special treatment. He shows little understanding or concern for the feelings of those around him, often exploiting them for his own gain. Which of the following is the most likely diagnosis?

Explanation

The patient's presentation is highly indicative of Narcissistic Personality Disorder (Cluster B). Key features include a pervasive pattern of grandiosity (in fantasy or behavior), a constant need for admiration, and a lack of empathy. Individuals with Narcissistic PD often have a sense of entitlement, believe they are special and unique, exploit others, and are often envious of others or believe others are envious of them. Their fragile self-esteem makes them highly sensitive to criticism, leading to rage or humiliation. Antisocial Personality Disorder (A) involves a pervasive pattern of disregard for and violation of the rights of others, often with deceitfulness, impulsivity, irritability, and a lack of remorse. While there can be overlap in exploitative behavior, the primary driver in Narcissistic PD is grandiosity and need for admiration, rather than a general disregard for rules or rights. Histrionic Personality Disorder (B) is characterized by excessive emotionality and attention-seeking behavior, often theatrical and dramatic, but typically lacks the grandiosity and exploitative nature of Narcissistic PD. Paranoid Personality Disorder (D) involves a pervasive distrust and suspiciousness of others, interpreting their motives as malevolent, which is not the central theme here.
