Primary pure spindle cell carcinoma (sarcomatoid carcinoma) of the ovary: A case report with immunohistochemical study | Diagnostic Pathology | Full Text
 

Case presentation

This case report refers to a sarcomatoid carcinoma of the ovary in in a 57 year-old woman with abdominal pain.

 Ovarian carcinosarcomas, also known as malignant mixed mesodermal tumors or malignant mixed Müllerian tumors, are exceedingly rare, and comprise only 1-3 % of ovarian malignancies [14, 15].

Conclusion

Primary ovarian spindle cell carcinoma is a rare neoplasm, which must be considered in the differential diagnosis of solid ovarian mass with spindle cell appearance. This case adds to our knowledge of the biological behavior of these rare neoplasms. The distinction from true sarcomas and carcinosarcomas is important because of the more favorable prognosis of the spindle cell carcinomas. However their diagnosis necessitates a careful tissue sampling and immunohistochemical staining.
