Mixed mesodermal tumor (MMT) arising from the ovary is very rare, but we recently encountered two cases of this tumor. The tumors were examined histologically using hematoxylin-eosin, alcian blue, periodic acid-Schiff (PAS), and toluidine blue staining, as well as immunohistochemical staining for S-100 protein. The two patients were postmenopausal women aged 68 and 58 years, respectively. The carcinomatous region of the mixed tumor was endometrioid carcinoma in Patient 1 and serous cystadenocarcinoma in Patient 2, while the sarcomatous region was chondrosarcoma in both patients. The chondrosarcoma tissue was positive for PAS, alcian blue, toluidine blue, and S-100 protein.

D010051	Ovarian Neoplasms	Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.

D002813	Chondrosarcoma	A slowly growing malignant neoplasm derived from cartilage cells, occurring most frequently in pelvic bones or near the ends of long bones, in middle-aged and old people. Most chondrosarcomas arise de novo, but some may develop in a preexisting benign cartilaginous lesion or in patients with ENCHONDROMATOSIS. (Stedman, 25th ed)	Chondrosarcomas
D003536	Cystadenocarcinoma	A malignant neoplasm derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. The neoplastic cells manifest varying degrees of anaplasia and invasiveness, and local extension and metastases occur. Cystadenocarcinomas develop frequently in the ovaries, where pseudomucinous and serous types are recognized. (Stedman, 25th ed)	Cystadenocarcinomas

D018199	Mixed Tumor, Mesodermal	A sarcoma of the body of the uterus arising in older women, composed of more than one mesenchymal tissue, especially including striated muscle cells. It is associated with previous pelvic radiation exposure in 20% of patients.

D018269	Carcinoma, Endometrioid	An adenocarcinoma characterized by the presence of cells resembling the glandular cells of the ENDOMETRIUM. It is a common histological type of ovarian CARCINOMA and ENDOMETRIAL CARCINOMA. There is a high frequency of co-occurrence of this form of adenocarcinoma in both tissues.
