ABSTRACT
Since the first description of delusional parasitosis by Thiebie`rge and Perrin, scientific work on the unshakable belief of being infested by parasites has been published under various terms. Thiebie`rge himself called the syndrome acarophobia (1). Perrin entitled his 1896 case-report ‘‘De ne´vrodermies parasitophobiques’’ (2). Other terms often found in the scientific literature are parasitophobia, entomophobia, delusions of infestation, monosymptomatic hypochondriacal psychoses, and Ekbom syndrome (3-8).
