Background: Immunohistochemistry is the definitive diagnosis in cases where a definite diagnosis cannot be made morphologically and histologically. IHC helps classify tumors. It also helps to solve the diagnosis problem of benign and malignant tumors. Material And Methods:  We studied 100 different ovarian epithelial tumors over a 2 year period. Three immune markers were included in the study. Result: Out of 100 case 70% are benign and 30%  aremalignant.Serous cystadenoma was most common benign lesion(60%)& among malignant lesions Serous cystadenocarcinoma was most common(60%).83.33% cases of serous carcinoma showed positivity for CK7 & 100% negativity for CK20 & CEA Conclusion: IHC helps to classify and confirm the histological diagnosis. IHC is particularly useful in solving the diagnostic problem of ovarian cancer and is poorly differentiated.
