Acute paranoid disorder and Klinefelter's syndrome.

A twenty-five-year old man presented with an acute paranoid disorder, and was subsequently diagnosed as having Klinefelter's Syndrome. Our review of previous reports suggests that the literature pointing out a particular association between Klinefelter's and schizophrenia may be misleading. In fact, Klinefelter's patients are liable to suffer from schizophrenia, paranoid disorders, or possibly other disorders.
