ABSTRACT

Introduction: the incidence of retroperitoneal tumors is low at childhood, but the fatality rate is very high. Although these tumors are classified into primary and secondary depending greatly on the tissue of origin, their cystic or solid form, benignancy or malignancy in pediatrics occurs since the neonatal phase.
Objective: to determine the incidence of retroperitoneal tumors in the university pediatric hospital of Centro Habana from January 2000 through December 2012.
Methods: a retrospective longitudinal and descriptive study of 77 patients who were treated at this center and diagnosed as retroperitoneal tumors from January 2000 through December 31st, 2012. The analysis variables were age, sex, symptoms and signs, type of tumor and treatment.
Results: in this group, 57 % were females, 60 % aged 0 to 5 years, and nephroblastoma was present in 50 % of cases. The reason for going to the doctor's was abdominal pain and fever (40 %) and the tumor was palpable in 80 %. Total resection was the elected surgery in all the cases. There were confirmed 39 nephroblastomas, 24 neuroblastomas and 6 renal cell carcinomas, among others. Neuroblastoma was the most frequent in boys whereas nephroblastoma was common in girls. In children aged under 5 years, nephroblastoma affected boys more and neuroblastoma was frequent in girls.
Conclusions: nephroblastoma (39 cases) followed by neuroblastoma (24 cases) were the most common retroperitoneal tumors found at the university pediatric hospital of Centro Habana in the period of 2000 through 2012. Abdominal echography detected tumors in all the cases, so this is the test of choice in the first stage of the study. The rapid progression of malignant tumors in pediatrics leads to considering palpated abdominal mass as an emergency in pediatrics.
