| Prevalence | rare |
Clear cell carcinoma of the uterine cervix, also cervical clear cell carcinoma, is a rare malignancy of the uterine cervix that classically is associated with diethylstilbestrol (DES) exposure. It typically occurs in younger women.
General
- Associated with diethylstilbestrol exposure in utero.[1]
- Less common in the cervix - when compared to other gynecologic sites.[2]
- More common in the endometrium.[3]
- Typical young women - median age ~38 in one series.[4]
Note:
- HPV does not appear to be important in the oncogenesis;[5] however, this is not completely settled.[6]
Microscopic
Features:[6]
- Cells with clear cytoplasm - key feature.
- May be focal/absent!
- Cells have large free/luminal surface area (hobnailing pattern) and small non-free surface.
- Moderate-to-severe nuclear pleomorphism.
- Tubular and/or cystic morphology.
- May be (simple) papillary and/or solid.
- Adenosis - typically adjacent.
DDx:
- Clear cell carcinoma of the endometrium - diagnosis based on clinico-radiologic correlation (IHC & histology not useful).[6]
- Serous carcinoma of the endometrium.
- Serous carcinoma of the uterine cervix.
- Mesonephric adenocarcinoma.

Features:[7]
- CK7 +ve.

- CK34betaE12 -ve.
