Comments:
When present in prostate needle biopsies, paraganglia must be distinguished from high-grade prostatic adenocarcinoma. Prominent vascular pattern, degenerative atypia, lack of immunoreactivity for PSA and PSAP, strong immunoreactivity for neuroendocrine markers (image shows positivity for Synaptophysin), presence of sustentacular cells with S-100 protein favor paraganglion.
