Review Question - QID 217797

A 14-year-old boy is brought to the emergency department with minor burns on his hand after he lit the shed behind the house on fire. His minor burns are cleaned and dressed with antibiotic ointment and gauze. During the treatment, his parents state that the boy has lit fires before and that they are worried because the fires are becoming increasingly destructive. When asked about this, the boy says that he loves the feeling of starting a fire and is aroused by seeing flames consume the objects. He says that he has no desire to hurt anyone and says that he doesn't see why what he did was wrong because he removed all the valuable objects from the shed before he set it on fire. Which of the following is the most likely diagnosis?
