Call–Exner bodies are small eosinophilic fluid-filled spaces between granulosal cells.[1] The granulosa cells are usually arranged haphazardly around the space.
They are usually associated with Granulosa cell tumor.
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.
They are named for Emma Louise Call and Sigmund Exner.[2]
