1.Diagnosis and surgical treatment of retroperitoneal tumors
Journal of Practical Medicine 2001;395(3):11-17
Retrospective study on the clinical and paraclinical features and results of treatment of some retroperitoneal tumors in 119 patients has found that the clinical symptoms, in generally were atypical. It is not difficult to diagnose the retroperitoneal tumor when combining many methods such as ultrasound, angiography, CT scanner, tumor markers but it is difficult to diagnose each kind of tumor.

Primary retroperitoneal neoplasms are rare, accounting for only 0.1-0.2% of all malignancies. Retroperitoneal location of leiomyoma are uncommon. Less than 2% of retroperitoneal tumors are leiomyomas. We report a case of huge retroperitonal leiomyoma mimicking solid adnexal mass with brief literature review.

4.Clinical, subclinical, pathological characteristics and management for postperitoneal tumors
Journal of Surgery 2007;57(5):23-33
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.

Retroperitoneal tumors are rare. They are asymptomatic, and are often found incidentally on abdominal computed tomograms (CTs). The patient reported here visited our hospital complaining of right flank pain. On abdominal CTs, a left-side retroperitoneal mass and a right ureteral stone were found. The hormonal study was normal. After surgical excision, the tumor was confirmed to be a bronchogenic cyst histologically, a very rare cause of retroperitoneal tumor. Our medical center has seen 15 cases with a soft tissue mass in retroperitoneal space over the past 5 years. Benign tumors were incidentally, while malignant tumors were often diagnosed after the patient complained of a palpable mass. In many of these cases, the radiologic impressions and pathologic diagnosis were inconsistent.

7.Retroperitoneal Leiomyoma of the Uterus Mimicking Sarcoma in Perimenopausal Woman: Case Report.
Journal of Menopausal Medicine 2014;20(3):133-137
Leiomyomas are very common benign tumors in the uterus and it is rare condition to present the retroperitoneal leiomyoma. The author reported a 48-year-old female patient who presented right pelvic mass with urinary incontinence and lower abdominal discomfort. Based on the preoperative imaging, provisional diagnosis was mesenchymal sarcoma. In the intraoperative findings, huge mass abutting to the uterus was observed in retroperitoneal space beneath the right broad ligament. After the exposure the retroperitoneal space, we encountered the well-demarcated tumor measuring 8 x 6 cm in diameter and this tumor attached the right surface of the uterus with fibrotic tissue. Pathologic findings demonstrated retroperitoneal uterine leiomyoma.

Bronchogenic cysts are usually located in the pulmonary parenchyma or in the mediastinum. When bronchogenic cysts are located in the mediastinum, they are usually near the bronchus or esophagus, and rarely located in the retroperitoneal space. It is difficult to differentiate between bronchogenic cysts and benign cysts prior to surgert. We report here on a patient for who had a mass in the retroperitoneum, with the preoperative diagnosis being a benign neurogenic tumor. Via left open thoracotomy, pathologic reports revealed that the mass was a bronchogenic cyst. We report here on the case of a bronchogenic cyst that was located in the retroperitoneal space of the diaphragm.

A Wilms' tumor is one of the most common primary retroperitoneal neoplasms in children, but the occurrence of an extrarenal Wilms' tumor is extremely rare, with only 60 well-documented cases in the literature. The behavior of the tumor appears to parallel that of similarly staged intrarenal tumors; hence, the staging and management protocols of intrarenal Wilms' tumor can be applied to those with an extrarenal location. Herein, the case of an 8-year-old male who developed an extrarenal Wilms' tumor in the retroperitoneal space, with multiple lung metastases, is reported.

A retroperitoneal Synovial Sarcoma is defined as a tumor arising in the retroperitoneal space, with an origin of mesodermal structures. The majority of synovial sarcomas (85 to 95%) occur in the extremities, located near the large joints. They are uncommon, and usually appear as a non- specific soft tissue mass, with no specific imaging feature. However, in some cases, radiological findings and anatomic location of the tumor may help the diagnosis. On CT examination, these tumors may be shown as hypo-dense masses and have an irregular enhancement in the periphery, with a poor enhancement in the central area, reflecting the necrotic, cystic and hemorrhagic changes. Histologically, there are two types of synovial sarcoma: biphasic and monophasic. Both types have about a 40% mortality rate. The known prognostic factors are; frequent mitotic figures, extensive tumor necrosis, and poor differentiation. Surgical ablation remains the mainstay of their management. Regardless of adequate surgical and adjunctive therapies, the recurrence rate ranges from 28 to 36%. Here, we present a case of a retroperitoneal synovial sarcoma, with a review of the literature.
