title: Obsessive-compulsive disorder and paraphilia in a monozygotic twin pair.
abstract: We report OCD and paraphilia in two male members of triplets (the two males being monozygotic twins), and discuss the possible aetiological factors for this previously unreported occurrence. We suggest that patients presenting with paraphilia should be examined for OCD and that a detailed sexual history should be obtained in all patients with OCD.
