Definition / general
  • Note: urothelial carcinoma of the ovary is now considered to represent a poorly differentiated form of high grade serous or endometrioid adenocarcinoma, and not be a distinct entity (Am J Surg Pathol 2013;37:1091)
  • 1-2% of surface epithelial tumors of ovary
  • Mean age 56 years, range 33-94 years
  • Resembles urothelial carcinoma of bladder but no coexisting Brenner component
  • Poorer prognosis than malignant Brenner tumor
  • Median survival for stage 3/4 disease is 28 months, similar to serous carcinoma (Hum Pathol 1996;27:12671)
Gross description
  • Mean 10 cm, range 3-30 cm, 60% solid and cystic, 41% bilateral
Microscopic (histologic) description
  • Undulating, diffuse, insular or trabecular patterns
  • Papillary structures lined by urothelium-like cells and nests of epithelial cells with high grade features, pale granular cytoplasm, large nucleoli or longitudinal grooves, separated by fibrous stroma
  • Usually necrosis
  • May have other ovarian epithelial components (usually serous)
