I present a case study in which the dramatic disappearance of the patient's chronic symptom of dyspareunia followed a critical episode in the treatment in which a core dynamic theme of defiance-punishment was enacted in the patient-therapist interaction. Symptomatic cure was not accompanied by the patient's explicit insight, but rather seemed to be a function of a complex process of test-passing and transference-countertransference enactments leading to the disconfirmation of a core unconscious pathogenic belief. Concepts of transference, transference cure, misalliance cure, and analysis of transference are discussed in the context of this case study.
