Abstract Background: Ovarian cancer is the most frequent cause of death from gynaecological cancers and the fourth most frequent cause of death from cancer in women in Europe, United States and India. The present study was conducted to assess distribution of neoplastic and non- neoplastic ovarian lesions. Materials & Methods: 74 patients age ranged 18- 48 years was recorded. The histological characterization of ovarian tumour was done according to the International Classification of Diseases, (WHO Classification, 1995). Results: Age ranged 18- 28 years had 24, 28-38 years had 40 and 38-48 years had 10. Common non- neoplastic lesions were simple serous cyst in 13, luteal cyst in 20, salpingo-oophoritis in 3, hemorrhagic cyst in 8 and endometriosis in 6 patients. Common neoplastic lesions were germ cell tumor seen in 12, epithelial tumors in 6, sex cord stromal tumour in 4 and metastatic tumors in 2 patients. The difference was significant (P< 0.05). Conclusion: Most common non- neoplastic lesions was simple serous cyst, luteal cyst and hemorrhagic cyst and neoplastic lesions was germ cell tumor.
