Aim: This study was undertaken to determine the frequency of ovarian lesions and their clinicohistological features. Materials and methods: A retrospective study was conducted for a period of 3 years on 1,844 cases of ovarian lesions in Jawaharlal Nehru Medical College, Ajmer, from July 2013 to June 2016. The specimens were analyzed macroscopically and studied microscopically. The non-neoplastic and neoplastic lesions were classified as per standard protocols. Results: In a total 1,844 cases of ovarian masses, 1,736 (94.14%) were non-neoplastic and 108 (5.86%) were neoplastic. Among neoplastic lesions, 71.29% (77/108) were benign, 2.78% (3/108) were borderline, and 25.93% (28/108) were malignant. The commonest non-neoplastic lesion was follicular cyst (66.59%) followed by corpus luteal cyst (26.73%). Surface epithelial tumor was the commonest histological type of ovarian neoplasm. The commonest benign tumor was serous cystadenoma (30/77) followed by dermoid cyst (28/77). The commonest malignant tumor was serous cystadenocarcinoma (8/28) followed by metastatic tumors to ovary (7/28). Mean age of the subjects was 41.54 years, ranging from 9 to 76 years. Conclusion: Non-neoplastic lesions outnumbered the neoplastic ones. Among the neoplastic lesions, epithelial histology was the dominant type. Only a provisional diagnosis can be made on clinical grounds, exact specification of the lesion requires its histopathological examination. Clinical significance: Histopathological findings of ovarian lesions are further helpful in treatment and prognosis of the patients.
