Common retroperitoneal tumors

Abstract

Introduction: retroperitoneal tumors (TRP) are defined as those solid or cystic, benign or malignant tumors that develop in the retroperitoneal space from tissues such as lymphatic, nervous, vascular, muscular and connective, among others. Due to its location, it is difficult to think about the diagnosis on many occasions. 
Objective: to characterize retroperitoneal tumors whose diagnosis allows us to understand its incidence frequency in morbidity and mortality. 
Methods: bibliographic review article, supported by documentary methodology, through digital databases: Pubmed, SciELO, Springer and Google Scholar, by descriptors in Health Sciences (DeCS), with inclusion criteria of articles published between the years 2018- 2022, in English and Spanish. 
Results: of the 20 selected articles, 55 % correspond to case reports, 30 % are review articles, 10 % are original works and 5 % were a presentation at an international congress. Regarding the world distribution by continents, by origin of the studies, 60 % were developed in America, 30 % in Asia and 10 % in Europe, finding that Africa and Oceania have not reported published research in the last five years. 
Conclusions: TRPs are rare pathologies, infrequent in the world, especially in Latin America, where, in turn, the scientific literature is few and limited. The clinical perspective is heterogeneous and non-specific, and can be confused with other pathologies that generally manifest as large abdominal masses; but, with organ preservation, discovered in working patients, producing challenges in terms of diagnosis and therapy for surgeons, radiologists and oncologists
