Abstract

Neuroendocrine tumors originate from neuroendocrine cell, so called APUD (amine precursor uptake and decarboxylation). Most neuroendocrine tumors have typical histopathology, immunohistochemical findings, and can be diagnosed by specific electromicroscopic feature of dense core granules. Neuroendocrine tumors are a diverse group of neoplasms that include carcinoid tumors, islet cell tumors, neuroblastoma, and small cell carcinoma. Neuroendocrine carcinoma of thymus bears similarities to neuroendocrine carcinoma in other organs, but it is clinicopathologically distinct from other tumors of thymus. Rare reports have been seen about thymus neuroendocrine carcinoma. Authors experienced a case of neuroendocrine carcinoma of thymus which cannot be classified as carcinoid, atypical carcinoid, or small cell carcinoma. Herein, we report this case with a review of the literatures.
