Background: Ovarian tumors represent a significant health issue in women, with varying clinical presentations and histopathological types. Accurate diagnosis and management are crucial for improving outcomes. This study aimed to assess the clinical presentation, histopathological diagnosis and their correlation in ovarian tumor cases at a tertiary hospital in Bangladesh. Methods: This retrospective study was conducted on 50 ovarian tumor cases diagnosed between June 2014 and July 2015 at the Obstetrics and Gynecology Department of BSMMU, Dhaka. Clinical and histopathological data were reviewed and the correlation between clinical and histopathological diagnoses was analyzed. Results: The majority of patients were between 20-40 years old (76%) and 68% were premenopausal. Abdominal pain (62%) was the most common symptom. Benign tumors were the most frequent histopathological finding (70%), followed by malignant (24%) and borderline tumors (6%). The most common histopathological subtypes were serous cystadenoma (38%) and mucinous cystadenoma (20%). The clinical diagnosis showed a 94.3% concordance for benign tumors, 83.3% for malignant tumors and 100% for borderline tumors, with an overall concordance of 92%. Conclusion: The study highlights the high concordance between clinical and histopathological diagnoses of ovarian tumors, emphasizing the importance of histopathological evaluation in the accurate diagnosis and management of ovarian tumors. Early detection and timely intervention are crucial in improving patient outcomes.
