Definition / general
  • Rare, resembles urothelial carcinoma but lacks true urothelial differentiation (J Low Genit Tract Dis 2005;9:149)
  • May behave aggressively with late metastases and local recurrence
  • Usually postmenopausal women who present at advanced stage (Eur J Gynaecol Oncol 1998;19:455)
  • Superficial biopsies with this pattern should be considered invasive until proven otherwise
Microscopic (histologic) description
  • Papillary architecture with fibrovascular cores lined by multilayered, basaloid / urothelial type epithelium with mitotic activity and without maturation, resembling HSIL
  • Stromal invasion is usually at base of tumor but may be within fibrovascular core
