摘要

A 60-year-old married woman presented with a history of general weakness, limb weakness, and vaginal bleeding for 1 month. After admission to our emergency department, she underwent dilation and curettage of endometrial tissue, and the pathology report was endometrioid carcinoma, grade 3. Computer tomography of the chest revealed one round nodule measuring 1.6 cm in size in the left lower lung lobe, and it was suspicious for metastatic endometrioid carcinoma. The patient underwent staging surgery for the uterine tumor. The pathological stage of endometrioid carcinoma was IB (T1b, N0, Mx). Three weeks later, the patient underwent computer tomography-guided biopsy of the lung tumor, and the pathological diagnosis was sclerosing pneumocytoma. She was followed up in our outpatient department after surgery for endometrioid carcinoma and biopsy of lung tumor. No enlargement of the sclerosing pneumocytoma lesion and no recurrent lesion of endometrioid carcinoma were noted after 5 years of follow-up. Sclerosing pneumocytoma typically presents as a unilateral pulmonary nodule, and this tumor typically behaves in a benign manner. In endometrioid carcinoma, the simultaneous appearance of sclerosing pneumocytoma may mimic a metastatic lung lesion.

一位60歲女性因全身及四肢無力、陰道出血一個月到急診求診，入院後病患接受子宮擴刮術採檢子宮內膜，病理診斷為子宮內膜癌。胸部電腦斷層檢查顯示左下肺有一個1.6公分大小的腫瘤，疑似子宮內膜癌轉移肺部，病患接受子宮切除分期手術，病理分期是IB。三週後病患接受肺部電腦斷層引導切片肺腫瘤，病理診斷為硬化性肺泡細胞瘤。病患於術後在門診追蹤五年，肺部腫瘤未明顯增大，子宮內膜癌也沒有復發。硬化性肺泡細胞瘤大多呈現單一肺部腫瘤，是良性的腫瘤，若同時有子宮內膜癌及硬化性肺泡細胞瘤，硬化性肺泡細胞瘤可能會被誤認是肺轉移病灶。
