Abstract
A case of ovarian endodermal sinus tumor (EST) following an operation on thyroid carcinoma is reported. The imprint cytology findings of EST were as follows:
1. The cell shapes were mostly cuboidal or columnar.
2. The various vacuoles were consistently seen in the cytoplasms, which were stained pale green by Papanicolaou's stain, and hyaline globules were sometimes seen also. The nuclear shapes were round or oval. The nuclear: cytoplasmic ratio was large, and the chromatin pattern was fine.
3. The nucleoli were prominent and enlarged. There were usually 2 or 3 in the nuclei.
The authors also checked for alpha feto protein (AFP) in the serum from the patient as a post-operative marker, in order to determine the possibility of a recurrence or metastasis, and this was also deemed useful in ascertaining the effect of anti-cancer agents on EST.
