[Delusional "pseudotranssexualism" in schizophrenic psychosis].

The case of a 32-year old man suffering from a 10-year course of schizophrenia is presented. The man's delusions include the conviction of being of the opposite sex and thus, he applied for an operational correction of his gender according to the law of transsexualism. Based on the evident problems arising from this case, the differential diagnosis of genuine transsexualism is discussed.
