Background: Postperitoneal tumors are diseases that are difficult diagnosis, vague and unspecific clinical signs. Objective: To take out experience for clinical practice based on clinical, imaging diagnosis, pathological characteristics and management for postperitoneal tumors. Subjects and method: A retrospective study included 93 cases that diagnosed and treated for postperitoneal tumors at Cho Ray Hospital from January 2000 to November 2006. Clinical, subclinical characteristics and theirs related factors; diagnosis, operation and prognosis for postperitoneal tumors were analysed. Results: The patients\ufffd?average age was 49.98\xb116.37 years (ranged 1-85 years); the ratio of male to female was 0.86. The average time from having pain symptom to admitting hospital was 4.49\xb110.01 months (ranged from 3 days to 60 months). Clinical symptoms were fatigue (51.5%), fever (15%), jaundice (45%), anemia (23.5%), weight loss (58%), abdominal pain (75%), abdominal distention (39%), digestive disorders (31%), touching tumor (50.5%)\ufffd?The diagnosis at admitting were right (32%), wrong (60%) and unclear (8%); the preoperative diagnosis were 70%, 22% and 8%, respectively. Pathologically, 39 of 93 cases (42%) were benign tumors, and 58% were malignant tumors. 61.3% of cases removed completely tumors, 2.15% removed partially tumors. The postoperative outcomes were good (62.6%), unimproved (28.57%), and bad (3.29%). There were some complications, included perioperative bleeding (2 cases - 2.19%), postoperative complication (3 cases - 3.29%), cracked colonic junction (1 case), renal bleeding (1 case) and peritonitis (1 case). Conclusions: The surgical treatment was main method for postperitoneal tumors. The complete tumor removing based on tumor\u2019s nature, stage and related structures.

Primary mucinous cystic cystadenomas of the retroperitoneum are very rarely encountered, and there have been only about 30 cases reported in the literature. The histogenesis of primary mucinous cystadenomas is unclear. Most authors suggested that it develops through mucinous metaplasia in a pre-existing mesothelium-lined cyst. Complete surgical excision is the only treatment and it is required for the final diagnosis and cure. We present here a case report of a 38-year-old Korean woman with primary retroperitoneal cystadenoma. It was a thin-walled, multilocular cyst with a dominant loculus that measured 10.0 X 7.5 X 5.5 cm3 in size, and to the best of our knowledge, this is the first such case to be reported in in Korea.

Primary retroperitoneal mucinous cystadenocarcinoma is a rare tumor. Only about 30 such cases have been reported in the worldwide literature, and a few Korean cases have been reported. The pathogenesis is not clear, and coelomic metaplasia of the retroperitoneal mesothelium has gained wide support. There is no consensus on the appropriate treatment, but surgical exploration is needed for the diagnosis and treatment, and adjuvant chemotherapy may be recommended following complete surgical excision. The long-term prognosis has not been established. We report here on a 32-year-old woman who was diagnosed as having a retroperitoneal mucinous cystadenocarcinoma with mural nodules of sarcomatoid change. Tumor excision and adjuvant chemotherapy were done and the patient is doing well without any evidence of recurrence at 42 months postoperatively.

OBJECTIVE: To explore and summarize the experience of surgical treatment for primary retroperitoneal tumor (PRT)in children. METHODS: Clinical data of 17 patients with PRT treated from January 2001 to January 2008 were retrospectively analyzed, including image examination, pathologic examination and surgical procedure. RESULTS: Seventeen patients underwent complete resection; 8 benign PRT, and 9 malignant PRT were diagnosed by operation and postoperative pathologic examination. Vascular surgery was done on 11 patients, 6 cases of multi-visceral resection, 1 vascular transplant, and 1 multi-visceral resection. Two patients had recurrent malignant PRT. CONCLUSION For pediatric complex retroperitoneal tumors, complete resection can reduce the recurrence and improve the long-term survival.
