Carcinosarcomas of the uterus and ovary: a clinicopathologic and immunohistochemical study of 11 cases.
OBJECTIVE
To further study the clinicopathologic features of carcinosarcomas of the uterus and ovary.


METHODS
We retrospectively studied all cases of uterine and ovarian carcinosarcomas diagnosed in our laboratory over the last 5-year period. The pathologic and immunohistochemical findings were correlated with the clinical records of the patients.


RESULTS
Eleven cases were retrieved . The commonest presenting symptom was vaginal bleeding (9 cases, 81.8%). Most patients (8 cases, 72.7%) were submitted to total abdominal hysterectomy with bilateral salpingo-oophorectomy and adjuvant chemotherapy was administered to all of them. In the majority of cases the tumor was located in the uterine corpus (7 cases, 63.6%), followed by the ovary (4 cases, 36.4%). The tumor was homologous in ten cases (90.9%) and heterologous in one case (9.1%). Most of our patients (6 cases, 54.6%) were diagnosed at an advanced stage (FIGO Stage III or IV). The sarcomatous element was strongly positive for vimentin in all cases and focally positive for cytokeratin 7 in four cases, while the epithelial component showed a strong positivity for cytokeratin 7 and focal staining for vimentin, cytokeratin 20, CA-125 and CEA.


CONCLUSIONS
Carcinosarcomas of the uterus and ovary are highly aggressive biphasic neoplasms with a prominent epithelial component. Their most common location is the uterine corpus. Although distant metastases are rarely found at the time of diagnosis, the prognosis of these tumors is unfavorable. The optimal chemotherapy remains to be determined.
