NCI Definition: A neuroendocrine neoplasm that arises from the lung. It is characterized by the presence of uniform polygonal cells with small or moderate amount of cytoplasm and inconspicuous nucleoli. The cells are usually arranged in organoid and trabecular patterns. It is classified as typical or atypical carcinoid tumor based on the number of mitotic figures and the absence or presence of necrosis. Atypical carcinoid tumors have a worse prognosis. [1]

Lung carcinoid tumors most frequently harbor alterations in MEN1, ARID1A, ATM, KMT2D, and ARID1B [2].

Most Commonly Altered Genes in Lung Carcinoid Tumor

MEN1 Mutation, ARID1A Mutation, KMT2D Mutation, ATM Mutation, and ARID1A Nonsense are the most common alterations in lung carcinoid tumor [2].
