Sertoli cell tumour of the ovary

Definition

An ovarian tumour showing, at least in part, a tubular pattern, analogous to Sertoli cell tumour of the testis.

Epidemiology

Sertoli cell tumours account for only 4% of all Sertoli-stromal tumours of the ovary. Ovarian Sertoli cell tumours occur in both adults and children. Some cases are associated with Peutz-Jegher's syndrome.

Clinical features

Patients may show estrogenic or androgenic effects.

Macroscopic appearances

Tumours are unilateral, solid and usually yellow. There may be limited cystic degeneration.

Histopathology

The tumour cells form solid or hollow tubules, trabeculae, diffuse sheets, pseudopapillae or islands. The tumour cells usually have pale to eosinophilic cytoplasm but may be foamy (lipid-rich Sertoli cell tumour). Nuclei are typically round to oval with inconspicuous nucleoli. Nuclear grooves may be apparent. The stroma is often abundant and may be sclerotic.

Nuclear atypia and a mitotic rate greater than 5/10 HPF are associated with malignant behaviour.
