It is an uncommon low-grade malignant lung mass that is most often in the central airways of the lung. It is also known as "atypical lung carcinoid tumour", " atypical lung carcinoid" or "moderately differentiated neuroendocrine carcinoma". It is a more aggressive than typical carcinoid tumors: nodal metastases in 70% vs. 5%.
By definition, they are greater than 4 mm in largest dimension; smaller lesions are referred to as pulmonary carcinoid tumourlets. [citation needed] The differential diagnosis of typical pulmonary carcinoid tumour includes: atypical pulmonary carcinoid tumour, pulmonary carcinoid tumourlet and lung adenocarcinoma.

Pulmonary neuroendocrine tumors are neuroendocrine tumors localized to the lung: bronchus or pulmonary parenchyma.. Pulmonary neuroendocrine tumors include a spectrum of tumors from the low-grade typical pulmonary carcinoid tumor and intermediate-grade atypical pulmonary carcinoid tumor to the high-grade pulmonary large cell neuroendocrine carcinoma (LCNEC) and pulmonary small cell carcinoma ...

In a retrospective review of 204 children with lung tumors, pleuropulmonary blastoma and carcinoid tumor were the most common primary tumors (83% of the 204 children had secondary tumors spread from cancers elsewhere in the body). [1] Pleuropulmonary blastoma is regarded as malignant. The male:female ratio is approximately one.
Due to presence of these tumors, DIPNECH is classified as a pre-malignant condition. [1] Although there have been reports of atypical carcinoids with local lymph node involvement, there are no reports of more aggressive neuroendocrine tumors, such as large cell neuroendocrine or small cell lung cancer, associated with DIPNECH.
