A 26-Year-Old Man Comes to the Office Accompanied by His

A 26-year-old man comes to the office accompanied by his wife, who says, "He needs help with a major anger problem that has been going on for years.  Every time I talk to a man, he becomes irrationally angry and jealous.  Whenever I am delayed due to traffic, he interrogates me about where I have been.  Last week, we had a big fight because he accused me of being unfaithful when I had to work late."  The patient says, "I'm only here because of my wife.  I can't have her turning against me too, though I'm sure she wishes she were with someone else."  The patient apologizes to his wife for his angry outbursts and attributes his behavior to being under stress at work.  He feels that his boss treats him unfairly and that his coworkers might be "setting me up to look bad."  He adds, "I had to leave my last job when I discovered that people were talking behind my back and the supervisor was deliberately giving me all the bad shifts."  The patient has no significant medical or psychiatric history.  He does not use alcohol or illicit drugs because he likes to "keep my head clear so I can anticipate when someone is trying to mess with me."  He acknowledges feeling depressed and anxious about his work situation and that he sometimes can't sleep because "I am up at night thinking about my problems."  The patient's maternal uncle was diagnosed with major depression and he thinks his maternal grandfather died in a "mental hospital."  On examination, the patient is alert and guarded.  Although non-spontaneous, he is cooperative in answering questions.  He describes his mood as "down."  He has no suicidal thoughts or auditory hallucinations.  Which of the following is the most likely diagnosis?

A) Borderline personality disorder
B) Delusional disorder
C) Major depression with psychotic features
D) Paranoid personality disorder
E) Schizotypal personality disorder
