Sertoli cell tumour is a sex cord-stromal tumour typically found in the testis. It is occasionally seen in women.
General
May be seen in several syndrome - esp. if there is calcification:
Microscopic
Features:
- Groups of cells in cords or trabeculae (beam-like arrangement).
- Cells have:
- Light staining bubbly cytoplasm +/- large cytoplasmic vacuoles.
- Slightly irregular nucleoli.
- Granular irregular appearing chromatin.
Negatives:
- Mitoses are rare.
- No significant nuclear atypia.
DDx:
- Granulosa cell tumour - may be very similar. Often has nuclear grooves.
- Epithelioid adenomatoid tumour.
- Sertoli cell nodule.
- Sertoli-Leydig tumour - esp. in ovary.

IHC
- Alpha-inhibin +ve (~95% of cases[4]).
- Calretinin +ve (~55% of cases[4]).
- Beta-catenin +ve (nuclear).[5]
- Negative beta-catenin should make one consider other diagnoses.[citation needed]
- May be negative in malignant sertoli cell tumours.
- SF-1 +ve.[6]
- Germ cell tumours -ve.
Others:
- WT-1 +ve.[4]
