The retroperitoneal tumors :epidemiology, diagnosis and treatment. About 7 cases and literature review

The primitive retroperitoneal tumors include all primary tumors arising from retroperitoneal and subperitoneal spaces excluding kidney, urinary tract, adrenal, large blood vessels and adjoining viscera. They are rares and their histology is varied. Their diagno-sis is often late. Complete surgical excision is the best treatment. In our study, we include adrenal tumors. The aim of our study was to evaluate the management of retroperitoneal tumors in our service. It was a retrospective and descriptive study from January 2006 to May 2014 in the General Surgery Department of the Aristide Le Dantec Hospital in Dakar. All patients with retroperitoneal tumor diagnosed in the CT scan were included. Seven patients’ files were included. We studied the epidemiology, diagnosis, treatment, and evolutionary of the retroperitoneal tumors. The retroperitoneal tumors incident rate during the study period was 0.01% of all tumors. They were 5 men and 2 women. The average age was 38.6 years. The mean time for diagnosis was 3 years. Abdominal pain was found in 5 patients (72%). High blood pressure upper than170/90 mm Hg was found in 1 patient (14%) and abdominal mass in all patients (100%). Specific laboratory test found elevated urinary vanillylmandelic acid to 5,4 ?mol/mmol of urinary creatinine in 1 patient. The abdominopelvic ultra-sound performed in all patients found abdominal tumor in 5 patients. Retroperitoneal and adrenal masses were found at ab-dominopelvic CT scan in 5 and 2 patients respectively. The mean diameter of tumors was 20.8 cm. Adrenalectomy was per-formed in 3 cases. Malignant adrenocortical carcinoma was found in 2 patients in the histological examination of surgical speci-mens. No patient received chemotherapy. One case of neuroendocrine tumor was reoccurred after 2 years. Four patients are alive. Retroperitoneal tumors are rare and their histological type is varied. Their diagnosis is often late. Complete surgical excision is the best treatment.
