來自於原發性大腸腺癌的Krukenberg卵巢腫瘤

A krukenberg ovarian tumor originated from primary colon adenocarcinoma

Krukenberg腫瘤是一種罕見的轉移性卵巢腫瘤，佔所有卵巢腫瘤的1至2%。轉移的來源最常見的是胃，其次才是腸道。本案例為少見轉移自大腸癌的Krukenberg腫瘤，個案年齡相當年。初始症狀為停經後出血，合併骨盆腔腫瘤。其中，因為CEA異常增高和大腸鏡的發現，使我們高度懷疑Krukenberg腫瘤的可能。案例最後被診斷為第四期大腸癌併右側Krukenberg腫瘤。案例討論將介紹轉移自大腸的Krukenberg腫瘤的疾病特徵、病理診斷以及現有的治療。

Krukenberg tumors are metastatic tumors to the ovary that contain well-defined histological characteristics, mucin-secreting ''signet ring'' cells, and most commonly originate from the gastrointestinal tract. It accounts for 1~2% of all ovarian tumors. The stomach is the most common primary site, followed by the large intestine. In this article, we present a rare type of Krukenberg tumor, that originated from the colon. Interestingly, the patient presents her initial symptoms as postmenopausal bleeding and a pelvic mass. After a thorough evaluation at our institute, she was eventually diagnosed with colon cancer, stage IV with a right ovarian Krukenberg tumor. Due to its rarity and atypical presentation, we also discussed the clinical-pathologic features and the current treatment of the Krukenberg tumor in this article.
