Classification
Cancer can be considered a very large and exceptionally heterogeneous family of malignant diseases, with squamous cell carcinomas comprising one of the largest subsets.
The International Classification of Diseases for Oncology (ICD-O) system lists a number of morphological subtypes and variants of malignant squamous cell neoplasms, including:
- Papillary carcinoma (Code 8050/3)
- Verrucous squamous cell carcinoma (Code 8051/3)
- Papillary squamous cell carcinoma (Code 8052/3)
- Squamous cell carcinoma (Code 8270/3)
- Large cell keratinizing squamous cell carcinoma (Code 8071/3)
- Large cell nonkeratinizing squamous cell carcinoma (Code 8072/3)
- Small cell keratinizing squamous cell carcinoma (Code 8073/3)
- Spindle cell squamous cell carcinoma (Code 8074/3)
- Adenoid/pseudoglandular squamous cell carcinoma (Code 8075/3)
- Intraepidermal squamous cell carcinoma (Code 8081/3)
- Lymphoepithelial carcinoma (Code 8082/3)
Other variants of squamous cell carcinoma are recognized under other systems, such as:
- Basaloid squamous cell carcinoma
- Clear-cell squamous-cell carcinoma
- Keratoacanthoma
- Signet-ring-cell squamous-cell carcinoma
