title: Characterization of papillary squamotransitional cell carcinoma of the cervix.
abstract: OBJECTIVE
  Does papillary squamotransitional cell carcinoma (PSTCC) behave differently from conventional squamous cell carcinoma of the cervix and does PSTCC have true transitional cell differentiation?
  
  
  METHODS
  Twenty cases of PSTCC were identified from archival files. Clinical data were compiled. Immunoperoxidase stains for uroplakin III, p63 and p16 were performed on available tissue blocks.
  
  
  RESULTS
  Patients ranged in age from 27 to 85 years. Twelve patients were FIGO Stage I, 4 were Stage II, and 2 were Stage III. Thirteen patients had clinical follow-up ranging from 5 to 132 months. Three patients subsequently had more extensive disease than initial clinical staging indicated. Nine patients had no tumor progression, three had local recurrence and one had metastatic disease. Eight cases were strongly immunoreactive for p63 and p16 and 14 were negative for uroplakin III.
  
  
  CONCLUSIONS
  PSTCC lacks true transitional cell differentiation and probably shares similar clinicopathologic features with conventional cervical squamous cell carcinoma.
