摘要

目的：探討闌尾低級別黏液性腫瘤（low-grade appendiceal mucinous neoplasm, LAMN）臨床病理學特徵及鑒別診斷。方法：分析5例LAMN的臨床資料，組織病理學特點及隨訪情況。結果：5例LAMN臨床症狀為右下腹疼痛、不適，下腹部腫塊，可伴發腹膜假黏液瘤，具有特定的病理結構和細胞學診斷特徵。結論：闌尾低級別黏液性腫瘤少見，容易誤診。正確的病理診斷至關重要。

Objective: To investigate the clinicopathologic features and differential diagnosis of low grade appendiceal mucinous neoplasm (LAMN). Methods: We retrospectively analyzed clinical details, histopathological features and follow-up data of 5 cases diagnosed with LAMN. Results: Clinical symptoms of patients diagnosed with LAMN consist of right lower abdominal pain and discomfort; right lower quadrant abdominal mass, sometimes accompanied by peritoneal pseudomucinous tumor with specific pathological and cytological diagnostic characteristics. Conclusion: LAMN is a rare disease and easy to be misdiagnosed. Accurate pathological diagnosis is essential for optimal management of patients with LAMN.
