Background: The aim of the study was to identify histopathological pattern involving in ovarian neoplasm which where received for histopathological evaluation at tertiary health care centre over a period of 2 year in Pathology department at Guru Gobind Government Hospital, Shri M. P. Shah Government Medical College, Jamnagar.Materials and Methods: This Prospective and Retrospective study was conducted over a period of two year (January 2020 to December 2022) in the Department of Histopathology, shri M.P, Shah Government medical college, Jamnagar. The study included 100 cases of ovarian neoplasms . After proper fixation and thorough gross examination, sections were routinely processed and examined. The distribution of the various histomorphological spectrum of ovarian tumors was studied according to the WHO classification. Aims and Objectives 1) To study frequency of ovarian tumor.2) To study their histopathological features.3) To study age wise incidence of ovarian tumor.Results: In the present study, a total of 100 cases of Ovarian neoplasm were analyzed, out of which Surface epithelial tumors were the most prevalent, comprising 70 cases (70%). Serous cystadenomas were the most common benign neoplasm encountered in our study. Germ Cell Tumors 22 (22%), Mature teratoma were most common germ cell tumor. Sex cord Stromal Tumors 07 (07%). The majority of our patients were in the age group 31-40 years (45 patients, 45% of patients).Conclusion: The present study shows various histopathological features of ovarian neoplasm. Benign tumors are more common than malignant tumors. Among the benign tumors, serous tumors were most common of all. Thus, an accurate histological diagnosis is important to initiate a proper management plan.
