title: Folie a deux and delusional disorder by proxy: an atypical presentation.
abstract: Delusion of parasitosis is a rare condition characterised by an individual harbouring the delusion of being infested with insects or parasites. We report a rare and interesting case of delusion of parasitosis presenting as folie a deux, that is, the delusion is shared by both the parents of an 18-month-old child, with proxy projection of parental delusion on the child. The case highlights the rare concomitant occurrence of two psychocutaneous disorders and emphasizes the importance of early recognition and appropriate intervention to safeguard the well-being of the child.
