===General===

*Most common small cell carcinoma outside of the lung.<ref name=pmid22110988/>
*Poor prognosis.
*Not graded (ISUP 2005 consensus on [[Gleason score]]<ref name=pmid16096414>{{Cite journal  | last1 = Epstein | first1 = JI. | last2 = Allsbrook | first2 = WC. | last3 = Amin | first3 = MB. | last4 = Egevad | first4 = LL. | title = The 2005 International Society of Urological Pathology (ISUP) Consensus Conference on Gleason Grading of Prostatic Carcinoma. | journal = Am J Surg Pathol | volume = 29 | issue = 9 | pages = 1228-42 | month = Sep | year = 2005 | doi =  | PMID = 16096414 }}</ref>).
 
===Microscopic===
Features:
*Small cells with:
**Nuclear moulding.
**Stippled chromatin.
**High [[NC ratio]].
*+/-High-grade acinar adenocarcinoma, i.e. conventional prostate carcinoma, seen in ~50% of cases.<ref name=pmid22110988/>
 
Notes:
*Similar to [[small cell carcinoma of the lung]].
*High-grade squamoid component favours metastatic [[urothelial carcinoma]].
**UCC usu. HWCK +ve.
 
DDx:
*[[Small cell carcinoma of the urinary bladder]].
*[[Lymphoma]], large cell.
*Other [[small round cell tumours]].
