Sertoli-Leydig cell tumour, also Sertoli-Leydig tumour, is a rare tumour of the gonad in the sex cord stromal group of tumours.
General
- Sertoli and leydig cells are normal in the testis.
- Poorly differentiated tumours have sarcomatous features.[1]
- May present with masculinization (virilization).[2]
Microscopic
Features:
- Sertoli or Leydig cells.[1]
- Leydig cells:
- Abundant solid eosinophilic cytoplasm.
- Round nuclei with fine chromatin and a small or indistinct nucleolus.
- Often in small clusters ~ 5-25 cells/cluster.
- Sertoli cells:
- Pale/clear vacuolated cytoplasm.
- Irregular nuclei with irregular/vacuolated-appearing chromatin.
- Architecture: tubules, cords or sheets.
- Leydig cells:
- Stroma.
- +/- Sarcomatous features (mucinous glands, bone, cartilage).
DDx:
- Endometrioid carcinoma of the ovary.
- Luteinized adult granulosa cell tumour - super rare, 50% of cell with eosinophilic cytoplasm, other findings of granulosa cell tumour, e.g. Call-Exner bodies.[3]
