Clear cell carcinoma of the uterine cervix
Diagnosis in short

Clear cell carcinoma of the gynecologic tract. H&E stain.
LM cells with clear cytoplasm (may be focal), hobnail pattern), moderate-to-severe nuclear pleomorphism, usu. tubular and/or cystic morphology (may be (simple) papillary and/or solid)
LM DDx cClear cell carcinoma of the endometrium, serous carcinoma of the endometrium, serous carcinoma of the uterine cervix, mesonephric adenocarcinoma, other clear cell tumours
Site uterine cervix
Clinical history +/-diethylstilbestrol (DES) exposure

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]

  • 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.

  • PR -ve.

Others - one case only:[8]

  • CA-125 +ve.
