Morphologic Spectrum of Neuroendocrine Tumors of the Prostate: An Updated Review.

CONTEXT.—: The incidence of neuroendocrine tumors of the prostate increases after hormonal therapy. Neuroendocrine tumors possess a broad spectrum of morphologic features and pose challenges in the pathologic diagnosis and clinical management of patients. OBJECTIVE.—: To present a brief updated summary of neuroendocrine tumors of the prostate with an overview of their histopathologic and immunohistochemical profiles and differential diagnoses. DATA SOURCES.—: Literature review, personal experience in the daily practice of pathologic diagnosis, and laboratory research. CONCLUSIONS.—: Our understanding of neuroendocrine tumors of the prostate classification and diagnosis continues to evolve. These advances benefit the risk stratification and management of prostate cancer.
