Overview
Primary lung cancers may be classified into two main categories: small cell lung cancer (~15%) and non small cell lung cancer (~85%). Non small cell lung cancer are a heterogenous group of lung cancers that are often grouped together because they share similar clinical features (e.g. prognosis and management). The 2004 WHO histological classification of tumors of the lung categorized lung tumors into malignant epithelial tumors, benign epithelial tumors, lymphoproliferative tumors, miscellaneous tumors, and metastatic tumors.
Classification
Primary lung cancers may be classified into two main categories:[1]
- Small cell lung cancer (~15%)
- Non small cell lung cancer (~85%).

- Papillary
- Clear cell
- Small cell
- Basaloid
Small cell carcinoma
- Combined small cell carcinoma
Adenocarcinoma
- Adenocarcinoma, mixed subtype

- Papillary adenocarcinoma
- Bronchioloalveolar carcinoma
- Nonmucinous
- Mucinous
- Mixed nonmucinous and mucinous or indeterminate
- Solid adenocarcinoma with mucin production
- Fetal adenocarcinoma
- Mucinous (“colloid”) carcinoma
- Mucinous cystadenocarcinoma
- Signet ring adenocarcinoma
- Clear cell adenocarcinoma
Large cell carcinoma
- Large cell neuroendocrine carcinoma
- Combined large cell neuroendocrine carcinoma
