Can a person have histrionic personality disorder with sociopathic behavior?

It is possible for someone to have histrionic personality disorder with sociopathic behavior, but this is not always the case. HPD is characterized by a pattern of excessive emotionality and attention-seeking behavior, while sociopathy is characterized by a lack of empathy and remorse. While these two disorders can co-occur, it is not necessary for someone to have both in order to have either one of them.
