Case 1. A 57-year-old female had hysterectomy 10 years ago because of leiomyoma uteri. She was recently found to have a clear-cut round mass shadow in the right middle lung field on her chest X-ray film 3. The mass was resected and microscopically diagnosed as metastatic leiomyosarcoma. Re-examination of the pathological specimen of the uterine tumor resected 10 years ago revealed 5-9 mitosis per 10 high-powered fields (/10 HPF). Case 2. A 54-year-old female who had undergone hysterectomy for myoma uteri 9 years previously was found to have a well-defined oval shadow in the left lower lung field which was resected and pathologically diagnosed as metastatic leiomyosarcoma. Her uterus lesion microscopically revealed 1-2 mitosis/10 HPF. The relationship between metastatic leiomyosarcoma of the lung and mitotic activity of leiomyoma uteri was discussed.
病例1。一名57岁女性10年前因子宫肌瘤接受了子宫切除术。最近她的胸部X线片3显示右肺中叶有一个清晰的圆形肿块阴影。该肿块被切除，显微镜检查诊断为转移性平滑肌肉瘤。对10年前切除的子宫肿瘤病理标本进行复查，发现每10个高倍视野（/10 HPF）有5 - 9个有丝分裂象。病例2。一名54岁女性9年前因子宫肌瘤接受了子宫切除术，发现左肺下叶有一个边界清晰的椭圆形阴影，该阴影被切除，病理诊断为转移性平滑肌肉瘤。她的子宫病变显微镜检查显示每10个高倍视野有1 - 2个有丝分裂象。讨论了肺转移性平滑肌肉瘤与子宫平滑肌瘤有丝分裂活性之间的关系。
