Detailed immunohistochemical analysis was done in 163 cases, which showed all of granulosa cell tumors positive for Inhibin, majority i.e. approximately 90% were positive for calretinin (n = 147) , 68% were positive for CD99 (n = 111), and a large number approximately 60% were also weak focal positive for Cytokeratins (n = 98). Here, CALB2 is linked to granulosa cell tumor.
