Neuroendocrine Tumors of the Lung: Updates and Diagnostic Pitfalls

Surg Pathol Clin. 2019 Dec;12(4):1055-1071. doi: 10.1016/j.path.2019.08.012. Epub 2019 Sep 27.

Abstract

Neuroendocrine tumors of the lung constitute approximately 20% of all primary lung tumors and include typical carcinoid, atypical carcinoid, small cell carcinoma, and large cell neuroendocrine carcinoma. Given their morphologic overlap with diverse mimics, neuroendocrine tumors of the lung can be diagnostically challenging. This review discusses the clinical, histologic, immunophenotypic, and molecular features of pulmonary neuroendocrine tumors, along with common diagnostic pitfalls and strategies for avoidance.

Keywords: Atypical carcinoid; Large cell neuroendocrine carcinoma; Small cell carcinoma; Typical carcinoid.
