The persistent genital arousal disorder (PGAD) may coexist with restless legs syndrome and overactive bladder syndrome and share some similarities with these conditions. Thus, the new term: restless genital syndrome (RGS) is proposed. The purpose of this paper is to present a case of PGAD, including the description of the etiology, the diagnostics and the treatment of the disorder. The described patient meets the criteria for PGAD. Organic lesions within nervous and urogenital system were excluded and the psychogenic background of the syndrome was assumed in this case. The patient was diagnosed with personality disorder with a predominance of dependent personality traits and emotional lability. After the failure of pharmacological treatment, systemic psychotherapy with cognitive-behavioral elements was initiated with moderate effect.
