ABSTRACTThis paper reports the clinical-pathological case of a male, 36-year-old patient, hospitalized due to moderate-severe abdominal pain, nauseas, vomit and palpable mass in the left inferior quadrant. Adbomen TAC reveled an expansive formation predominantly cystic in the left side of retroperitoneum. During exploratory laparotomy, exeresis of retroperitoneal cystic tumor was done, which was complicated with renal vein laceration, which was suturated. Macroscopically, tumor weighted 139 g, it was cystic, multilobular, recovered partially by beige adipose tissue; when opening the specimen a dark brown and hematic of gel aspect liquid flowed, allowing to see several cystic formations of 2-5 cm with cell detritus covered by a brownish-gray mucose, of papillomatous surface and rughby touch. Microscopically mature cartilaginous tissue was seen, as well as cylindrical ciliated and mucous, squamous, urothelial, nervous epithelium, with great histoplasmocytic reaction. Teratomas are neoplasms of germinal cells constitute by two or more germinal layers. They are more frequent in children, but may affect adults in different sites, retroperitoneal one is little frequent. This paper presents a bibliographic review and of the histogenesis of this kind of tumors, as well as its differential diagnosis.
