Struma ovarii is a special type of ovarian dermoid cyst and accounts for approximately 2-3 % of all dermoid tumours. Benign struma ovarii may manifest as distant metastasis, called peritoneal strumosis, which makes it biologically similar to malignancy, and has been reported in limited cases but never discovered during pregnancy.
We report a patient with a history of right struma ovarii cystectomy. During pregnancy, pelvic masses with non-specific clinical presentation were found again. During the caesarean section, contralateral struma ovarii with dissemination of nodules in the peritoneal cavity was found, and pathology revealed that the masses were thyroid follicle ovarian goitres. DISCUSSION AND CONCLUSIONS: Recurrent benign struma ovarii with extraovarian dissemination is a rare aggressive clinical manifestation different from malignancy. It is emphasized that adequate assessment and complete resection of suspicious masses are of great importance.
卵巢甲状腺肿是一种特殊类型的卵巢皮样囊肿，约占所有皮样肿瘤的 2-3%。良性卵巢甲状腺肿可能表现为远处转移，称为腹膜甲状腺肿，这使其在生物学上类似于恶性肿瘤，在有限的病例中已有报道，但从未在怀孕期间发现。
我们报告了一位有右侧卵巢甲状腺肿囊肿切除术病史的患者。在怀孕期间，再次发现盆腔有非特异性临床表现的肿块。在剖宫产术中，发现对侧卵巢有结节播散的卵巢甲状腺肿，病理显示肿块为甲状腺滤泡性卵巢甲状腺肿。
复发性良性卵巢甲状腺肿伴卵巢外播散是一种罕见的侵袭性临床表现，不同于恶性肿瘤。强调对可疑肿块进行充分评估和完整切除非常重要。
