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.

WHO Histological Classification of Tumors of the Lung

The World Health Organization (WHO) classifies tumors of the lungs as follows:[1]

Malignant Epithelial Tumors

Squamous cell carcinoma

Small cell carcinoma

  • Combined small cell carcinoma

Adenocarcinoma

  • Nonmucinous
  • Mucinous
  • Mixed nonmucinous and mucinous or indeterminate
  • Solid adenocarcinoma with mucin production

Large cell carcinoma

  • Combined large cell neuroendocrine carcinoma

Adenosquamous carcinoma

Sarcomatoid carcinoma

  • Pleomorphic carcinoma
  • Spindle cell carcinoma
  • Giant cell carcinoma
  • Carcinosarcoma
  • Pulmonary blastoma

Carcinoid tumor

  • Typical carcinoid
  • Atypical carcinoid

Other tumors that may affect the lungs

Salivary gland tumors
  • Mucoepidermoid carcinoma
  • Adenoid cystic carcinoma
  • Epithelial-myoepithelial carcinoma
  • Preinvasive lesions
  • Squamous carcinoma in situ
  • Atypical adenomatous hyperplasia
  • Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia
Mesenchymal tumors
Benign Epithelial Tumors
  • Squamous cell papilloma (either exophytic or inverted)
  • Glandular papilloma
  • Mixed squamous cell and glandular papilloma
  • Alveolar adenoma
  • Papillary adenoma
  • Adenomas of the salivary gland type
  • Mucinous cystadenoma
Lymphoproliferative Tumors
  • Marginal zone B-cell lymphoma of the MALT type
  • Diffuse large B-cell lymphoma
  • Lymphomatoid granulomatosis
  • Langerhans cell histiocytosis
Miscellaneous Tumors
  • Mature Teratoma
  • Immature Teratoma
  • Other germ cell tumors
