Enfermedad de Castleman retroperitoneal : a propósito de un caso.

Background: A case of 35- year old patient with a retroperitoneal Castleman disease which is exceptionally rare is presented. Objective: This illness in he localized from can have on extensive ghost of presentation that in occasions it poses great troubles of differential diagnosis. We expose a hialina-vascular case that it show like a only retroperitoneal masse, we do emphasis in the classifications and briefly revise the literature. Clinic case: Male of 35 years old who is admitted at the hospital for epigastric pain in left hipocondrio accompanied of vomits and constitutional syndrome. The physical exam and the lab test made were normals except for VSG of 60 mm/1 h. The imagenologic methods showed through abdominal ultrasonography a retroperitoneal mass well defined of 5 x 4 x 3 cm, which was confirmed by computerized axial tomography. The biopsy and histopathology study were refused by the patient, so the removal of the mass was practiced. The histopathology study of the piece shows that it was a retroperitoneal angiofolicular linfoide hyperplasia localized in it vascular variety. Conclusions: Retroperitoneal Castleman disease is a very rare entity that occasionally develops like one mass. The differential diagnosis must be done with primary retroperitoneal masses generally malignant. Since the histopathology studies are not conclusive for that reason, the positive and differential diagnosis must be anatomopatologic.
