Histologically, there are nests of transitional epithelial urothelial cells with longitudinal nuclear grooves coffee bean nuclei lying in abundant fibrous stroma
Transitional cell carcinoma is an even rarer entity, in which neoplastic transitional epithelial cells similar to transitional cell carcinoma of the bladder are seen in the ovary, without the characteristic stromal/epithelial pattern of a Brenner tumour
It is named for Fritz Brenner 1877–1969, a German surgeon who characterized it in 19074 The term "Brenner tumor" was first used by Robert Meyer, in 19325
