If inhibin, calretinin, cd99 are true negative, the chance of granulosa cell tumor is very low.
CK-Pan is positive. Please show photos.
morphology favors a fibromatous lesion. More stains (CK) confirm the type of the lesion. Then you can consider the the degree of the lesion, bengin or malignant or borderline. Also you can stain a smooth muscle marker
