atypical frotteurism associated with voyeurism and obsession in a six-year-old boy

introduction: frotteuristic sexual interest is a rare psychiatric disorder characterized by at least six months of recurrent and intense sexual arousal from touching or rubbing against a non-consenting person, usually in a crowd. case presentation: a six-year-old boy was referred to the psychiatrist while accompanied by his mother and grandmother with the complaint of excessively rubbing his genitalia many times a day against his female family members’ bodies, primarily their buttocks. conclusions: experts are advised to focus on diverse sexual history dimensions, especially uncontrollable masturbation behaviors, that can predict sexual interests. although frotteurism is a rare psychiatric disorder, and although this case is atypical given the early childhood presentation of abnormal sexual behavior carried out secretly and not in a crowd, it is clear that frotteurism is the appropriate diagnosis after ruling out other more common disorders.
