Micrograph of a<unk> . H&E stain. High magnification micrograph of a<unk>  showing the characteristic coffee bean nuclei. H&E stain. Histologically, there are nests of transitional epithelial (urothelial) cells with longitudinal nuclear grooves (coffee bean nuclei) lying in abundant fibrous stroma. Also recall that the "coffee bean nuclei" are the nuclear grooves exceptionally pathognomonic to the sex cord stromal<unk> , the ovarian granulosa cell<unk> , with the fluid-filled spaces Call-Exner bodies between the granulosa cells.
