摘要

成熟囊狀畸胎瘤是由至少兩種胚胎層組織所組成；典型的成熟畸胎瘤延著中線或縱軸兩側發生，最常見的發生位置在薦尾骨部位，生殖器官，以及縱膈腔。然而到目前為止，文獻上從未報導過共同發生的縱膈腔畸胎瘤與卵巢畸胎瘤。我們報告一位年輕女性因為卵巢成熟囊狀畸胎瘤接受左側部份卵巢輸卵管切除術及腫瘤切除。術前胸部X光顯示有前縱膈腔腫瘤；十五個月後的胸部X光顯示前縱膈腔腫瘤明顯增大。前縱膈腔腫瘤的病理結果也是成熟囊狀畸胎瘤；前縱膈腔畸胎瘤包含部份胰臟組織，但卵巢畸胎瘤並未包含任何胰臟組織。雖然共同發生的縱膈腔畸胎瘤與卵巢畸胎瘤極少見，但臨床醫師也不能忽略這種可能性。

Mature cystic teratomas are tumors consisting of tissue from at least 2 of the 3 primitive germ layers. Mature teratomas typically occur in midline or para-axial regions. The most common locations are the sacrococcygeal regions, gonads, and mediastinum. However, the simultaneous occurrence of mediastinal and ovarian teratomas has never been reported in the literature. We herein report a young female who received a left partial oophorosalpingectomy and tumor excision for an ovarian mature cystic teratoma. Pre-operative chest X-ray revealed an anterior mediastinal tumor. Chest X-ray taken 15 months later demonstrated obvious interval growth of the anterior mediastinal tumor, which pathologically also showed mature cystic teratoma. The mediastinal teratoma contained small areas of pancreatic tissue, whereas the ovarian teratomas did not show any pancreatic tissue. Although the incidence is rare, the possibility of concomitant mediastinal and ovarian teratomas could not be overlooked.
