摘要

Background. Account for less than 1% of all gastrointestinal tumors, primary appendiceal malignancies are rare and their diagnoses are usually made after exploratory laparotomy. Most of them present with nonspecific symptoms, such as abdominal pain, abdominal fullness and huge pelvic mass, mimicking advanced stage ovarian cancer. Case Presentation.We described a menopausal women who was referred to our institution under the impression of advanced stage of primary ovarian cancer. However, the patient was eventually found to have primary appendiceal adenocarcinoma with ovarian metastasis at laparotomy. Initial symptoms, intraoperative finding, pathology finding, and postoperative clinical courses were recorded. Conclusions. Comparing with primary ovarian tumor, ovarian metastasis is relatively rare. The clinical picture can be misleading and the differential diagnoses of primary appendiceal cancer should be considered when preoperative workup is planned.

背景：原發闌尾惡性腫瘤僅佔所有腸胃道惡性腫瘤的百分之一以下，且常於剖腹探查時術中診斷。病人常表現出非特異性症狀，如腹痛、腹脹、或相似於晚期卵巢癌的巨大骨盆腔腫瘤。個案報告：我們描述了一位經診斷為晚期原發性卵巢癌並轉診至本院的停經後婦女。然而，此患者在術中診斷為闌尾惡性腫瘤併卵巢轉移。術前表現、術中發現、病理報告及術後臨床病程皆被記錄。結論：相較於原發性卵巢癌，卵巢之轉移性惡性腫瘤相對少見。臨床表徵常誤導診斷者，而在術前評估時，闌尾原發惡性腫瘤須列入鑑別診斷。
