Both non-neoplas c as well neoplas c ovarian tumors are common. In the present study neoplas c ovarian tumors were analyzed for their age of occurrence, site of ovary involved and histological typing. Oophrectomy/Hysterectomy and Oophrectomy was performed on pa ent suff ering from ovarian tumors and the specimens were sent to Pathology department LMC & Teaching Hospital for their histological study. The present study of 40 cases of ovarian neoplasm is from 2068/05/05 B.S. to 2070/05/30 B.S. The mean age of pa ent was 39 years with S.D of 1.25 years. The size of the tumor varies from 5 cm to 32.9 cm and weight varies from 41 gms to 350 gms. Commonest tumor was mature cys c teratoma (52.5 %) followed by serous cyst adenoma (30%). Not much diff erence was found for ovarian tumor regarding its site right and le ovary. Only two cases of malignant ovarian neoplasm were found in this study, one case (2.5 %) was of immature cys c teratoma and another (2.5 %) was of serous cyst adenocarcinoma. Keywords: INTRODUCTION Ovarian cysts, both neoplas c and non-neoplas c are quiet common. No age is immune on developing ovarian tumors. Non-neoplastic cysts are mostly related to hormonal imbalance but neoplas c ones are due to some gene c and acquired causes. The tumors may arise from surface epithelium, germinal epithelium and stromal cells of the ovary. They are classifi ed on the basis of their origin. This study was carried out on clinically diagnosed ovarian tumors and its histological typing in Lumbini Medical College & Teaching Hospital. MATERIALS AND METHODS The study comprised of 40 numbers of ovarian tumors diagnosed in the Obstetrics & Gynecology department in LMC & Teaching Hospital from 2068/05/05 B.S to 2070/05/30 B.S. A er obtaining clinical details regarding age and symptoms which were lower abdominal discomfort, dysmenorrhoea and irregular menstrual cycle. The opera ve procedure Oophrectomy/Hysterectomy with Oophrectomy was done and specimens were subjected to Department of Pathology for their histological examina on. RESULTS In the present study 40 cases of clinically diagnosed ovarian tumors were analyzed for age group, site of the ovary involved and histological typing of neoplasm. From the above table it appears that the maximum number of 12 cases (30 %) was found in age group of 31-40 years followed by 10 cases (25%) in the age group 41-50 years. Prac cally same incidences of 7 cases each (17.5%) were found in the age group of 21-30 years and 51-60 years. Mean age group for ovarian tumor was found to be 39 years with S.D of 1.25 years. So far the site of ovarian tumor is concerned the commonest site was right ovary 21 cases (52.5%) and le ovary 17 cases (42.5%). Bilateral ovarian involvement was found in only 2 cases (5%). Most common ovarian tumor in present study was Mature cystic teratoma 21 cases (52.5 %) followed by Serous Cyst adenoma 12 cases (30 %). Mucinous cyst adenoma was found in 4 cases (10 %). One case (2.5 %) each was of Brenner tumor (Benign type), malignant serous cyst adenoma and immature cystic teratoma. DISCUSSION The mean age for ovarian tumor in the present study was 39 years with S.D of 1.25 years. The mean age for ovarian tumor of 38 years was reported by Pudasaini et al1 and 33 years by Ghimire et al.2 Commonest age for ovarian neoplasm in the present study was 31-40 years and prac cally with the same incidence of 25 % with mean age group of 41-50 years. Youngest age group for ovarian neoplasm in the present study was 10-20 years (5%). 71 S Jain et al Table 1: Showing age groups of Ovarian Tumors S.N Age Group (In Years) No. of cases Percentage 1 11-20 2 5% 2 21-30 7 17.5% 3 31-40 12 30% 4 41-50 10 25% 5 51-60 7 17.5% 6 61- 70 2 5% Total no. of cases 40 100 % Table 2: Ahowing the site of involvement S.N Site No. of cases Percentage 1 Right 21 52.5 % 2 Le 17 42.5 % 3 Bilateral 2 5 % Total 40 100 % Table 3: Showing the morphological types of ovarian neoplasm S.N Morphology No. of cases Percentage 1 Serous cyst Adenoma 12 30 % 2 Serous cyst adenocarcinoma 1 2.5 % 3 Mucinous cyst adenoma 4 10 % 4 Brenner’s Tumor (Benign) 1 2.5 % 5 Mature Cys c Teratoma 21 52.5 % 6 Immature Cys c Teratoma 1 2.5 % Total 40 100 % So far the site of ovary involved in ovarian neoplasm is concerned there was not much diff erence as compared to Right ovary (52.5%) and Le ovary (42.5%). Bilateral ovarian neoplasms were seen in only 5 % of cases in the present study. Bilateral ovarian tumors involvement was reported in 8.49 % of cases by Ghimire et al but its higher incidence of 18.6 % was observed by Pudasaini et al.1 Benign ovarian tumors were common in present study (95 %). A similar incidence of 83.9 % was reported by Jha and Karki,3 87.3 % by Pudasaini et al and 89.42 % by Ghimire et al. Somewhat lower incidence of 72.9 % was reported by Gupta et al.4 Germ cell tumor, mature cys c Teratoma was commonest ovarian tumor 21 cases (52.5 %) in the present study. The mature cys c teratoma was also observed to be commonest tumor by Jha et al, Ghimire et al, Thurlbeck WM et al,5 Peterson WF,6 Dhakal et al8 and Sha et al.9 Surface epithelial tumors consisting of serous cyst adenoma, mucinous cyst adenoma and benign Brenner tumor were seen in 17 cases (42.5 %) in present study. Similar observa on of 48.8 % has been reported by Gupta et al, 52.5 % by Jha and karki et al and 43.6 % by Ghimire et al. Yasmin et al7 has reported somewhat higher incidence of 76.5 %.

Incidence of malignant immature teratoma of 9.43 % was observed by Ghimire et al. CONCLUSION Ovarian neoplasms were clinically seen from the age group of 15 – 60 years. Majority of the ovarian tumors were unilateral. Maximum numbers of ovarian neoplasm were benign germ cell tumor, mature cys c teratoma followed by benign surface epithelial tumor serous cyst adenocarcinoma. Only two cases of malignant ovarian neoplasm were observed, one case was of immature cys c teratoma and another case was of serous cyst adenocarcinoma. REFERENCES 1.
