Overview
Carcinoid tumor of the gastrointestinal tract may be classified based on the location into three subtypes (foregut, midgut, or hindgut). Carcinoid tumor of the lung may be classified based on the histology into two subtypes (typical and atypical). Carcinoid tumor of the ovary may be classified into four subtypes (insular, trabecular, strumal, and mucinous type).[1][2]
Classification
1. Carcinoid tumor in the gastrointestinal tract
Carcinoid tumor of the gastrointestinal tract may be classified based on the tumor location in the primitive gut into three subtypes:
2. Carcinoid tumor in the lung
Based on the histology
Carcinoid tumor of the lung may be classified based on the histology into two subtypes:[2]
- Typical carcinoid tumors of the lung
- Atypical carcinoid tumors of the lung
Based on the location
Carcinoid tumor of the lung may be classified based on the location into two subtypes:[2]
- Bronchial carcinoid tumors: central lesions
- Peripheral pulmonary carcinoid tumors: peripheral lesions
3. Carcinoid tumor in the ovary
Carcinoid tumor of the ovary may be classified into four subtypes:[1]
- Insular type (most common)
