"The small cell component of immunohistochemistry stains usually expresses neuroendocrine markers as synaptophysin, neurone-specific enolase, chromogranin or CD56 1. About half of the tumours show positivity in thyroid transcription factor (TTF-1) 2,3. Typical prostatic markers as the prostate-specific antigen (PSA) or P501S are only positive in about 1/6 to 1/4 of the cases 1."
"Fusions of the TMPRSS2 and ERG genes might be found with small cell carcinomas of the prostate 1-3. Other mutations include the N-MYC and the RB1 gene 4."

"Due to relatively low prostate-specific antigen (PSA) levels in relation to tumour extent, tumour detection is more difficult and patients frequently present with voiding difficulties, haematuria, constitutional or neurological symptoms due to paraneoplastic syndromes or metastases. They might also be incidentally found on imaging studies 1-4."
"Tumour markers such as CEA, CA19-9, plasma CgA, neurone-specific enolase, 5-hydroxytryptamine, bombesin or gastrin might be positive 1."
