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]
  • 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]

  • 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.
