Sertoli cell tumor of the testis. Report of a case with imprint cytology findings.
BACKGROUND
Sertoli cell tumor of the testis is a relatively rare neoplasm, and few reports concerning its cytologic findings have been previously documented.


METHODS
A 41-year-old male had Sertoli cell tumor in the left testis. An imprint smear revealed tumor cells showing a less cohesive or singly dispersed cell pattern. The cytoplasm was faintly stained, and most tumor cells were naked. The nuclei were oval or short and spindle in shape, and some of them showed coffee bean nuclei or nuclear indentation.


CONCLUSIONS
Coffee bean nuclei can be observed in Sertoli cell tumor.
