Dysgerminoma of the ovary associated with hypercalcemia.
A 19-year-old female presented with a 3-week history of abdominal swelling, polydipsia, and polyuria. Ultrasound examination disclosed a right adnexal mass. Preoperative workup showed that the serum calcium level was evaluated to 12.2 mg/dl. Laparotomy disclosed a right ovarian tumor and a right salpingo-oophorectomy was performed. The serum calcium level fell to within the normal range postoperatively. The ovarian tumor was a typical dysgerminoma on both gross and microscopic examination. The majority of ovarian tumors associated with paraneoplastic hypercalcemia in young females are small cell carcinomas of hypercalcemic type. It is important, however, for pathologists to be aware that the dysgerminoma is the second most common ovarian neoplasm associated with hypercalcemia in this age group, as diagnostic confusion between these two tumors may rarely occur on microscopic examination. The literature on ovarian tumors associated with hypercalcemia is briefly reviewed.
