===General===
{{Main|Sertoli cell tumour}}
*Arises from ''Sertoli cells'' ([[AKA]] nurse cells).
 
May be seen in several syndrome - esp. if there is calcification:
*[[Carney complex]].<ref name=pmid21047926>{{Cite journal  | last1 = Libé | first1 = R. | last2 = Horvath | first2 = A. | last3 = Vezzosi | first3 = D. | last4 = Fratticci | first4 = A. | last5 = Coste | first5 = J. | last6 = Perlemoine | first6 = K. | last7 = Ragazzon | first7 = B. | last8 = Guillaud-Bataille | first8 = M. | last9 = Groussin | first9 = L. | title = Frequent phosphodiesterase 11A gene (PDE11A) defects in patients with Carney complex (CNC) caused by PRKAR1A mutations: PDE11A may contribute to adrenal and testicular tumors in CNC as a modifier of the phenotype. | journal = J Clin Endocrinol Metab | volume = 96 | issue = 1 | pages = E208-14 | month = Jan | year = 2011 | doi = 10.1210/jc.2010-1704 | PMID = 21047926 }}</ref>
*[[Peutz-Jeghers syndrome]].
 
===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]].
