[Ovarian steroid cell tumors: a bilateral form]

The authors report a case of bilateral ovarian steroid cell tumour, not otherwise specified (as subclassified now by Scully). For two years a 46-year-old woman had androgenic manifestations. Only plasma testosterone level was increased. A hysterectomy with bilateral ovariectomy was performed. The first diagnosis was bilateral Leydig cell tumour, but no Reinke crystal was found. The final diagnosis was steroid cell tumour, not otherwise specified. No significant nuclear atypia or mitotic activity were found and two-year follow-up was favourable. The authors discuss the difficulty to class some ovarian tumours between Leydig cell tumour and steroid cell tumour, not otherwise specified as defined by Scully.
