Testicular Tumors: A 15-Year Archive Review and Histopathological Evaluation

Abstract

Aim: Testicular tumors are one of the most common malignancies in men in the age group of 15-40 years, although they are rarely observed. In our study, it was aimed to evaluate their histopathological features by retrospectively examining of the cases diagnosed as testicular tumor in our department. Materials and Methods: Age, tumor localization, tumor size, pathological stage, tumor type and frozen information of 65 cases diagnosed as testicular tumor in the Department of Medical Pathology at Tokat Gaziosmanpasa University Faculty of Medicine between 2006-2020 were examined. Results: The mean age of 65 cases diagnosed as tumor was 37.9±17.73 years. Their ages ranged from 1 to 78 years. Macroscopic tumor diameter was an average of 4.6 ± 2.36 cm, 36 (55.4%) of them were located in the right and 29 (44.6%) of them were located in the left testis. Histopathological diagnosis was germ cell tumor in 53 (81.7%) cases and non-germ cell tumor in 12 (18.3%) cases. The most common tumor was seminoma with 22 (33.9%) cases and the second was mixed germ cell tumor with 19 (29.3%) cases. In components forming mixed germ cell tumors, embryonal carcinoma was the most commonly seen. Intraoperative frozen section examination was performed in 17 cases, it was determined that 10 cases were malignant and 7 cases were benign. Conclusion: The histopathological and general features of our series of testicular tumor was determined to be compatible with the literature to a great extent. Intraoperative frozen section examination is an important auxiliary diagnostic method in terms of organ preserving surgery.
