Microscopic examination of granulosa cell tumor shows predominantly granulosa cells with pale, grooved, "coffee bean" nuclei. The characteristic microscopic feature is the Call-Exner body--a rosette arrangement of cells around an eosinophilic fluid space. Menometrorrhagia and postmenopausal bleeding are common signs and reflect a prolonged exposure of the endometrium to estrogen. Similarly, breast enlargement and tenderness are common associated complaints. Tumor markers, inhibin B seems to be more accurate than inhibin A.
