| Popis: | A 26-year-old woman was hospitalized with a retroperitoneal mass. She had been in excellent health until 2 months earlier, when she started suffering episodes of dyspepsia and back pain. Physical examination and laboratory tests of urine and blood were normal. Abdominal ultrasonography and computerized tomography revealed a 3.2 1.9 cm retroperitoneal solid cystic polylobulated mass situated between the left psoas muscle and hilum of the left kidney. The mass did not infiltrate any structure. Computerized tomogram guided needle biopsy showed hematinic cells and a few histiocytes, although no malignant cells were found. A course of observation was initially followed. Six months later magnetic resonance imaging demonstrated that the mass had grown to 7 2 2 cm with internal septae. Excretory urography revealed displacement of the first portion of the left ureter, with no compression signs. Physical examination and complete blood and urine tests remained normal. Due to its benign nature and the age of the patient, laparoscopic resection of the tumor was elected. We used transperitoneal dissection with 4 trocars. The mass, located around the left ureter, under the renal vein and external to the gonadal vein, exhibited cysts with serohemorrhagic content. Duration of surgery was 3 hours, and there were no complications. There was no significant blood loss and the tumor was removed intact in a bag through an enlarged trocar site. Postoperative course was uneventful and the patient was discharged from the hospital 3 days later. Pathological finding was a 6 1.5 2 cm grayish multicystic specimen (see figure). Immunohistochemical study with vascular marker CD34 showed endothelial features. Final histological diagnosis was retroperitoneal venous hemangioma. DISCUSSION |
