Ovarian Endometrioid-like Yolk Sac Tumor Treated by Surgery Alone, with Recurrence at 12 Years

Abstract We describe the case of a stage Ia endometrioid-like yolk sac tumor (YST) of the ovary, which was originally misdiagnosed as a malignant struma ovarii and not treated with adjuvant chemotherapy. After 12 years, a contralateral dermoid cyst was excised along with a small omental nodule of partially necrotic and calcified endometrioid-like YST. No tumor was detected in several other biopsy specimens, and a peritoneal lavage was negative for tumor cells. Since there was no evidence of remaining tumor and the serum α-fetoprotein (AFP) level was normal after the second operation, the patient was followed. Serial serum AFP levels remained normal for 4 months. At a second-look laparotomy …

Struma ovarii is a rare form of ovarian neoplasm, entirely or predominantly composed of thyroid tissue. This tumour generally has a benign biological behavior, although some cases of malignant transformation have been reported (5-10%). The tumour usually presents as an asymptomatic mature mass that may measure as much as 10 cm in diameter. The presence of ascites is possible (15-20%), and in a few cases the association of ascites and hydrothorax has been recorded (Pseudo-Meigs Syndrome); a close relationship between ascites and high levels of Ca-125, that may wrongly induce to a diagnosis of ovarian carcinoma is present. Other possible clinical consequences are compressive symptoms on adjac…
