===General===
{{Main|Transitional cell carcinoma of the ovary}}
*Rare.
*Traditionally in the ''transistional cell tumours'' category - in the surface epithelial group of ovarian tumours.<ref name=Ref_WMSP401>{{Ref WMSP|401}}</ref>
*Thought to be related to high-grade [[serous carcinoma of the ovary|serous carcinoma]].<ref name=pmid23018212>{{Cite journal  | last1 = Ali | first1 = RH. | last2 = Seidman | first2 = JD. | last3 = Luk | first3 = M. | last4 = Kalloger | first4 = S. | last5 = Gilks | first5 = CB. | title = Transitional cell carcinoma of the ovary is related to high-grade serous carcinoma and is distinct from malignant brenner tumor. | journal = Int J Gynecol Pathol | volume = 31 | issue = 6 | pages = 499-506 | month = Nov | year = 2012 | doi = 10.1097/PGP.0b013e31824d7445 | PMID = 23018212 }}</ref>

*Cystic spaces:
**Small - punched-out border - very common.
**Large.
*Papillae, usu. large, blunt.
**Occasionally small and filiform.
*+/-Bizarre giant cells (35%)
*+/-Gland-like tubules.
*+/-Squamous differentiation.
*+/-[[Psammoma bodies]].
*Cells:
**Moderate basophilic cytoplasm and little intervening stroma.
**Marked nuclear pleomorphism.
**Mitoses - common.
