Mixed mesodermal tumor
of the ovary: analysis of prognostic factors in 31 cases.
In view of its complex histologic architecture, TCS has also been known as malignant teratoma, blastoma, and mixed mesodermal tumor
Characteristics of cell lines established from a mixed mesodermal tumor
of the human ovary: carcinomatous cells are changeable to sarcomatous cells.
15] They may occur as both benign (adenofibroma and adenomyoma variants, an intermediate variant [atypical polypoid adenomyoma]) and malignant variants (adenosarcoma, carcinosarcoma [malignant mixed mesodermal tumor
, malignant mixed mullerian tumor], and carcinofibroma).
Fibroepithelial polyps are benign mesodermal tumors
of the ureter composed of a fibrovascular core lined by normal urothelium.
Cancers that developed after long-term tamoxifen therapy tended to be mixed mesodermal tumors
or sarcomas of the endometrium rather than less invasive types.
13,14) Specific IHC stains, especially desmin, have helped to improve the accuracy of diagnosis and differentiate LMS from other mesodermal tumors
, such as fibromas, fibrosarcomas, spindle-cell sarcomas, rhabdomyosarcoma, malignant melanomas, and inflammatory myofibroblastic tumors.
Type II carcinomas include high-grade serous carcinoma, high-grade endometrioid carcinoma, undifferentiated carcinoma, probably some clear cell carcinomas, and malignant, mixed mesodermal tumors
