Gynecological cytology and biopsy revealed immature adenocarcinoma cells. Laparotomy demonstrated the tumor originating from the uterine corpus, disseminating to the bladder and peritoneum. The uterus and both adnexa were resected. The white and soft tumor located in the fundus uteri was diagnosed as MMMT including adenocarcinoma, chondrosarcoma, leiomyosarcoma and rhabdomyosarcoma. Post operative anticancer chemotherapy was performed.
she died of ileus caused by disseminating peritoneal metastasis 6 months after the operation. Autopsy findings showed that all abdominal organs were adhered by tumor metastasis. Histologically, the tumor consisted mainly of sarcomatous component based on mucinous stroma. This finding may indicate that poor prognosis is affected by sarcomatous component of the tumor.
