Abstract
Certain ovarian tumors are capable of producing a hormonal effect. The mere presence of altered endocrine activity in no way indicates an ovarian tumor or the need for immediate exploratory laparotomy, but the possibility of a functioning tumor must be considered when an ovarian tumor is palpable and the patient's story suggests endocrinopathy. Complete hysterectomy and bilateral salpingo-oophorectomy seem preferable to the risk of leaving residual tumor in a conserved ovary, especially since oral hormonal therapy is so satisfactory, but if the patient desires children a conservative surgical approach appears justified in view of the low recurrence rate. In any case, removal of the tumor assures fairly prompt return to a normal sexual pattern from the spectacular changes produced by these uncommon tumors.
