Background: Ovarian neoplasms exhibit a wide variation in structure and biological behaviour. There are numerous types of ovarian tumours, and over all they fall into benign, borderline, and malignant categories. Ovarian carcinoma represents the sixth most common female cancer and the fourth leading cause of death due to cancers in women. Aims:__ampersandsignnbsp;To study the clinical presentation and pathological patterns of ovarian tumours. Materials and Methods:__ampersandsignnbsp;The clinicopathological study was at ASCOMS Sidra Jammu, in the department of pathology. This was a prospective observational study conducted over a period od 1 year (Nov 2014 to Oct 2015). Results:__ampersandsignnbsp;A total of 189 cases of ovarian lesions were studied, of which 119 were neoplastic and 70 were non-neoplastic. Maximum cases 26.1%__ampersandsignnbsp;were reported in the age group of 41-50 years. Among 70 non-neoplastic lesions, luteal cyst was commonest comprising 48.5%__ampersandsignnbsp;of total non-neoplastic lesions. Of 119 neoplastic lesions 56.3%__ampersandsignnbsp;were benign, 1.7%__ampersandsignnbsp;were borderline and 42%__ampersandsignnbsp;were malignant. Tumours were classified as per WHO classification 2003. The surface epithelial group formed the largest group constituting 74.8%__ampersandsignnbsp;of all the ovarian neoplasms, followed by germ cell tumours (16%), metastatic tumours (5.9%), sex cord stromal tumours (1.7%)__ampersandsignnbsp;and miscellaneous (0.84%). Among the individual neoplasms, serous tumours were the commonest (59.7%), followed by teratomas (13.4%). One case each of endometriod carcinoma, clear cell carcinoma, mixed epithelial carcinoma, thecoma, fibroma, yolk sac tumour, struma ovarii and lymphangioma was also reported in the present study. Conclusion:__ampersandsignnbsp;Ovary is a frequent site of primary and metastatic tumors. Due to its complex structure, primary ovarian neoplasms are of diverse histological types. Our observations and results proved to be valuable baseline information regarding patterns of ovarian tumors in our population. More studies, to define the risk factors in our population and to identify specific etiological factors, are recommended.
