Retroperitoneal tumors: A retrospective review of 14 patients

Objective: In this study, we evaluated the pathological results and clinical presentation of patients with retroperitoneal tumors Design: Retrospective study Setting: Department of Urology at Hitit University, Çorum Erol Olçok Training and Research Hospital, and Department of Urology at Haydarpaşa Numune Training and Research Hospital Subjects: Fourteen patients with retroperitoneal tumors Intervention: Retroperitoneal mass and clinical suspicion of tumor Main outcome measures: The symptoms at presentation and pathologic reports of the tumors were recorded in these patients. Results: Of the patients evaluated for retroperitoneal tumor, eight patients were male. The mean age of the study group was 55.7 ± 11.4 years with a range of 41 to 75 years. Liposarcoma was the most common pathological diagnosis of the retroperitoneal tumors in these patients (35.7%). Schwannoma and gastrointestinal stromal tumor were reported in two patients. The other retroperitoneal masses were diagnosed as atypical lipomatous tumor, paraganglioma, myelolipoma, lipomatous hemanjiopericytoma and Castleman disease. Conclusion: Retroperitoneal tumors are rare neoplasms in daily urological practice. With the development of radiological imaging techniques in recent years, most of the patients have been diagnosed incidentally at abdominal imagings for other purposes. The management of these patients is important because of the aggressive behavior of sarcomas.
