子宫内膜原发性鳞状细胞癌在女性生殖器官恶性肿瘤中是极为罕见的类型。子宫内膜癌常以腺癌为主,腺棘癌次之,鳞状细胞癌则少见,迄今国内外文献报道约18例,可见其发病率很低。一、临床资料我院自1964年4月～1985年12月共收治子宫内膜癌688例,其中经临床及病理证实为子宫内膜原发性鳞状细胞癌者共6例占0.87％。由于病例过少,发病率不能说明问题。本组年龄为48～80岁,平均为61.5岁。与文献报道符合。生育次数为1～8胎,除一例未婚外,均为多胎经产。 6例患者均已绝经,最短者2年,最长者29年,平均10.3年。诊断时间:2例在一年以上,1例因子宫脱垂术后病理确诊,毫无自觉症状。 Endometrial primary squamous cell carcinoma is a very rare type in female genital malignancies. Endometrial cancer often adenocarcinoma, followed by adenocarcinoma, squamous cell carcinoma is rare, so far about 18 cases reported in the literature at home and abroad, we can see its incidence is very low. First, the clinical data of our hospital since April 1964 to December 1985 were treated 688 cases of endometrial cancer, of which clinically and pathologically confirmed endometrial primary squamous cell carcinoma in a total of 6 cases accounted for 0.87%. As the number of cases is too small, the incidence can not explain the problem. The group is 48 to 80 years old, with an average of 61.5 years old. In line with the literature. The number of births is 1 to 8, except one case of unmarried, are multiple births. All 6 patients had menopause, the shortest was 2 years, the longest 29 years, an average of 10.3 years. Diagnosis time: 2 cases in more than one year, 1 case pathologically confirmed by uterine prolapse, no symptoms.
