Large-cell carcinoma (LCC), like small-cell carcinoma (SCC) is very rare and only accounts for about 5% of all cervical cancers. Early-stage LCC are extremely aggressive and difficult to diagnose due to the sub-mucosal location of the tumor and intact overlying mucosa. As with SCC, in LCC early cases are asymptomatic.

Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
Cervical cancer typically develops from precancerous changes called cervical intraepithelial neoplasia over 10 to 20 years. [3] About 90% of cervical cancer cases are squamous cell carcinomas, 10% are adenocarcinoma, and a small number are other types. [4] Diagnosis is typically by cervical screening followed by a biopsy.

Cervical adenocarcinoma is less likely to be caused by high-risk HPV strains than cervical squamous cell carcinoma is: around 10-15% of cervical adenocarcinomas are non-HPV-related. Cervical clear cell carcinoma (CCC) is typically HPV-negative, though many are p16 positive. [3]
The diagnosis is based on tissue examination, e.g. biopsy. [citation needed]Under the microscope, glassy cell carcinoma tumours are composed of cells with a glass-like cytoplasm, typically associated with an inflammatory infiltrate abundant in eosinophils and very mitotically active.
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
