Fascin can be an auxiliary immunomarker of ovarian granulosa cell tumors: comparison with calretinin and inhibin-alpha.
The histopathologic diagnosis of granulosa cell tumor adult type (AGCT) can be supported by the use of established immunomarkers such as inhibin-alpha and calretinin. Previously unreported data is presented on the detection of fascin in AGCT, in nonneoplastic granulosa cells and in other types of sex-cord stromal tumors. In addition, by staining a panel of various tumors, potentially included in the differential diagnosis of AGCT, we assessed the value of fascin as an auxiliary AGCT immunomarker. Intense and strong fascin staining may assist in cases with ambiguous calretinin or inhibin-alpha staining. On the contrary, absence of fascin should question a provisional morphologic diagnosis of AGCT.
