title: Primary non-gestational uterine cervical choriocarcinoma with metaplastic transformation from squamous cells.
abstract: BACKGROUND
  Primary non-gestational uterine cervical choriocarcinoma is very unusual and although it has been hypothesized that it can arise by metaplastic transformation of cervical epithelium, solid evidence has been lacking.
  
  
  METHODS
  Primary non-gestational uterine cervical choriocarcinoma was diagnosed in a 47-year-old, woman undergoing tubal resection 17 years previously. A histologically- and immunohistochemically-confirmed, non-gestational cervical choriocarcinoma could be diagnosed in which there was metaplastic transformation from squamous cells . The patient underwent 5 courses of an actinomycin-D chemotherapeutic regimen and radical hysterectomy with bilateral pelvic lymphadenectomy.
  
  
  CONCLUSIONS
  Primary non-gestational uterine cervical choriocarcinoma may indeed arise from metaplastic transformation of epithelial tissue.
