绒毛膜上皮细胞癌(简称绒癌)是发生于滋养细胞的恶性肿瘤。肿瘤的恶性程度高,肺转移多见,但对化疗高度敏感。采用大剂量化疗可使大多致病例获愈,手术治疗绒癌的肺转移瘤仅限于少数经反复多个疗程化疗,肿瘤吸收至一定程度不再缩小或产生耐药的病例。孙成孚、王元萼等关于肺切除治疗绒癌肺转移已作报道。本文报道2例绒癌肺转移误诊误治的教训。例1 45岁。咳嗽、咯黄痰2年,右下肺发现一肿物7月余伴憋气入院。9年前曾患葡萄胎做过刮宫术,以后月经正常,3～4/10天。此后顺娩2胎,无不规则阴道出血史。查体,右下胸部呼吸音
Chorionic epithelial cell carcinoma (referred to as choriocarcinoma) is a malignant tumor that occurs in trophoblastic cells. The degree of malignancy of the tumor is high. Lung metastases are more common but highly sensitive to chemotherapy. High-dose chemotherapy can be used to recover most cases. Surgical treatment of pulmonary metastases of choriocarcinoma is limited to a small number of patients undergoing multiple cycles of chemotherapy. Tumors absorbed to a certain extent will no longer shrink or develop resistance. Sun Chengfu and Wang Yuanji have reported on lung resection for the treatment of choriocarcinoma lung metastasis. This article reports the lessons of misdiagnosis and mistreatment of lung metastases in 2 cases of choriocarcinoma. Example 1 45 years old. Two years after coughing and jaundice, a tumor was found in the right lower lung for more than 7 months and admitted to hospital with hernia. 9 years ago he had had a hydatidiform mole and had a normal menstrual period, 3 to 4/10 days. Since then, Shun 2 children, no history of irregular vaginal bleeding. Examination, breath sounds in the lower right chest
