"Adenocarcinoma of the prostate with neuroendocrine differentiation is an acinar or ductal adenocarcinoma that does not feature any typical neuroendocrine morphology as e.g. nuclear moulding in small cell carcinoma or peripheral palisading in prostatic large cell neuroendocrine carcinoma but is characterised by the positivity of one of three neuroendocrine markers chromogranin A, synaptophysin or CD56 1,2."

"Immunohistochemistry stains are usually positive for at least one neuroendocrine marker as chromogranin A, synaptophysin or CD56 2. Prostate-specific antigen (PSA) is usually positive in the adenocarcinoma and variably positive in the neuroendocrine cells 2."
