Sex cord tumour with annular tubules, abbreviated SCTAT, is an uncommon sex cord tumour.
It is not sex cord tumour with angulated tubules.
General
- Associated with Peutz-Jeghers syndrome.[1]
- Large tumours more likely sporadic.
- Small tumours more likely Peutz-Jeghers syndrome and incidental.
- Usually benign.
- Malignant cases reported.[2]
Microscopic
Features:
- Well-circumscribed nests of cells with nuclei at the periphery.
- Annular tubules (ring-shaped tubules) with dense hyaline material.
Notes:
- Annular = shape of a ring.[3]
- May focally have features of Sertoli cell tumour or granulosa cell tumour.[4]
DDx:
- Sertoli-Leydig tumour - has double palisading with overlap of the layers.
- Granulosa cell tumour - have Call-Exner bodies, which don't have a well-defined/solid content.
- Brenner tumour - coffee-bean nuclei.
