cancer lungs: 2

Lung cancer is usually classified according to primary histology types and all have a natural history and response to treatment varies. Although there are more than a dozen types of lung cancer primary, but bronkogenik cancer, including four first types of cells is 95% of all lung cancers.

Practical division for medicinal purposes: a). small cell lung cancer (SCLC), b). NSCLC (non small cell lung cancer / squamous carcinoma, adenocarcinoma, large cell carcinoma).
1999 WHO histological classification for tumors and pleural tumors: (2)
Epithelial tumors:
1. Benign: papilloma, adenoma
2. Preinvasive lesion: squamous dysplasia / carcinoma in situ, atypical adenomatous hyperplasia, diffuse idiopathic pulmonary neuroendocrine cell hyperplasia.
3. Malignant:
1. Squamous cell carcinoma: papillary, clear cell, basaloid.
2. Small cell carcinoma: combined small cell carcinoma
3. Adenocarcinoma:
• Acinar
• Papillary
• bronchoalveolar: nonmusinous, musinous, musinous and nonmucinous mixed or indeterminate cell type

• Solid carcinoma with mucin formation
• Adenocarcinoma with mixed subtypes
4. Large cell carcinoma: neurondocrine Large cell carcinoma, Basaloid carcinoma, Lymphoepitelioma-like carcinoma, Clear cell carcinoma, Large cell carcinoma with rhabdoid phenotype
5. Adenosquamous carcinoma
6. Carcinoma with pleomorphic sarcomatoid or sarcomatous elements
7. Carcicoid tumors: typical carcinoid, atypical carcinoid
8. Salicary gland carcinomas of type: mucoepidermoid carcinoma, adenoid cystic carcinoma
4. Others: soft tissue tumors
5. Mesothelial tumors: Benign, Malignant mesothelioma
6. Miscellaneous tumors
7. Lymphoproliferative diseases
8. Secondary tumors
9. Unclassified tumors
10. Tumor like lesions
