Sarcomatoid squamous cell carcinoma of the uterine cervix with osteoclast-like giant cells: report of two cases.

Two postmenopausal women with sarcomatoid squamous cell carcinoma (SSCC) of the uterine cervix are described. This report brings the total number of reported SSCCs in the lower female genital tract to 11. The gross and microscopic features of our SSCCs were similar to those of SSCCs in the digestive and upper respiratory tracts with the additional finding of osteoclast-like giant cells in each case. The behaviour and differential diagnosis of these tumors are briefly discussed.
