Call–Exner bodies, giving a follicle-like appearance, are small eosinophilic fluid-filled punched out spaces between granulosa cells.[1] The granulosa cells are usually arranged haphazardly around the space.
Call–Exner bodies marked with black circles in an intermediate-high magnification micrograph of a granulosa cell tumour, a type of sex cord stromal tumour. H&E stain.
Histologically, these tumors consists of monotonous islands of granulosa cells with "coffee-bean" nuclei. That same nuclear groove appearance noted in Brenner tumour, an epithelial-stromal ovarian tumor distinguishable by nests of transitional epithelial cells (urothelial) with longitudinal nuclear grooves (coffee bean nuclei) in abundant fibrous stroma.[2][3]
They are composed of membrane-packaged secretion of granulosa cells and have relations to the formation of liquor folliculi which are seen among closely arranged granulosa cells.
