MHP has been divided into 4 main categories: Delusions of infestation (including parasitosis); delusions of dysmorphophobia, such as of misshapenness, personal ugliness, or exaggerated size of body parts (this seems closest to that of body dysmorphic disorder); delusions of foul body odours or halitosis or delusional bromosis (also known as olfactory reference syndrome); and a miscellaneous group.
