A 60-year-old female visited Guihang Guiyang Hospital (Guiyang, China). She presented with abdominal pain in the right side for the previous 2-months, with a touchable mass identified for the previous 1-month. Computed tomography with magnetic resonance imaging revealed a huge mass in the right abdomen. The diagnosis of well-differentiated retroperitoneal liposarcoma with renal involvement was made. During surgery, the tumor was removed, including the fatty renal capsule; however, the kidney was preserved. It is currently debatable whether resection of adjacent organs is required to obtain the negative margins...

BACKGROUND: Retroperitoneal paragangliomas (PGs) are a rare subgroup of neuroendocrine tumors that are commonly located alongside the abdominal aorta. Complete tumor resection is thought to be restricted in patients with major blood vessel involvement. However, no study has specifically focused on aggressive surgical treatment in such patients. We evaluated the value of en bloc resection with major blood vessel reconstruction for locally invasive retroperitoneal PGs. METHODS: Twenty-nine patients with retroperitoneal PGs with major blood vessel involvement were included in this retrospective study...

INTRODUCTION: The role of percutaneous biopsy to characterize large, locally advanced and metastatic primary renal tumors has not been well described. The goal of this article is to describe the potential advantages of biopsy for preoperative evaluation of patients with large renal tumors and advanced disease. METHODS: Literature was reviewed for percutaneous biopsy and for locally advanced and metastatic renal tumors. RESULTS: Multiple studies have confirmed that percutaneous biopsy is safe, and the cost is minimal relative to the cost of surgical operation...

PURPOSE: There has been an increased utilization of the posterior retroperitoneal approach (PRA) for adrenalectomy alongside the "classic" laparoscopic transabdominal technique (LTA). The aim of this study was to compare both procedures based on outcome variables at various ranges of tumor size. METHODS: A retrospective analysis was performed on 204 laparoscopic transabdominal (UMC Groningen) and 57 retroperitoneal (UMC Utrecht) adrenalectomies between 1998 and 2013...

WAGR syndrome is caused by an 11p13 deletion and includes Wilms' tumor, aniridia, genitourinary anomalies and mental retardation. We encountered a case of a dysgerminoma originating in an ectopic ovary in a woman with WAGR syndrome. Our patient was a 24-year-old nulliparous woman who was diagnosed with WAGR syndrome. The patient had undergone left nephrectomy for a Wilms' tumor and postoperative chemotherapy at the age of 7 months. She also had a history of glaucoma surgery in both eyes, and was followed up at the Department of Pediatrics for diabetes mellitus, hypertension, liver dysfunction and hyperuricemia...

Retroperitoneal sarcomas are rare malignant neoplasms that are often diagnosed late because of their typical nonspecific symptomatology. Radical surgical resection, if possible given the local anatomical conditions, is the most important treatment modality. However, even if the surgery is feasible and successful, the prognosis of retroperitoneal sarcoma is not good. The most frequent type of recurrence is local recurrence, and radical surgical resection remains the most important treatment modality even in such cases...

Extraosseous osteogenic sarcoma is a very rare malignant neoplasm. The most common sites are the extremities, thorax, and the abdomen. Retroperitoneal osteosarcomas are rare and very few cases have been reported. They are similar in their biology to high-grade soft tissue sarcomas. R0 resection appears to be the best possible treatment for these tumors but there are no published cases on how to manage them when it involves posterior and intra-spinal regions. We report a 62-year-old male who presented with a backache, and investigations revealed a large retroperitoneal fibrosarcoma invading into the lumbar spine, but was found to be an extra osseous osteosarcoma on final histopathological examination...

A 58-year-old female presented with renal colic and was found to have renal transitional cell carcinoma at the time of percutaneous surgery. She developed percutaneous tract seeding that clinically presented as subcutaneous skin nodules. After local treatment with surgical excision and radiation treatment, the patient developed retroperitoneal recurrence 5 years later. Percutaneous tract seeding is rare. There is no general consensus on prevention of tract seeding during percutaneous resection of renal urothelial tumors...

Background: The development of laparoscopic and robotic surgeries represents the modern era with the objective of improving patient outcomes; this surgical method is widespread in urology and general surgery. Retroperitoneal laparoscopic/robotic surgery is common in urologic surgery, but not in liver surgery. Tumors located in the posterosuperior aspect of the liver are difficult to access using a transperitoneal approach, and control of bleeding can also be difficult, especially in patients with cirrhosis...

Primary neuroendocrine tumors of the upper urinary tract are extremely rare. We report a case of de novo small cell carcinoma of the ureter that presented masquerading as a distal ureteral stone. A 55-year-old lady presented to our clinic with 1 month history of right lower back pain and hematuria. Her history was notable for stage 1B mixed clear cell-endometroid cancer of the uterus status post radical abdominal hysterectomy with adjuvant radiotherapy, 7 years before the current episode. The patient had no evidence of recurrence...

We report on a 45-year-old man who presented with pain in the left leg, which he had had for 2 months. A contrast-enhanced CT scan displayed a 25-mm tumor in the lateral side of the left psoas muscle. For this suspected retroperitoneal tumor, we performed laparoscopic resection of the tumor, which was encapsulated by the funicular femoral nerve, using surgical scissors rather than a surgical energy device and preserved the normal fascicles wherever possible. Pathological examination indicated a benign ancient schwannoma arising from the femoral nerve...

REVIEW
David Berger-Richardson, Carol J Swallow
To evaluate histologic subtype and grade, which in turn guide the decision making for multimodality therapy, the workup of suspected sarcoma requires more material than can be obtained from a fine-needle aspiration. Either open or percutaneous core needle biopsy is indicated before a management decision is made. Percutaneous biopsy of a potentially malignant lesion is controversial, given the perceived potential for tumor seeding along the needle tract. However, the evidence that the latter is a significant risk is weak at best...

BACKGROUND: Although gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, they comprise less than 1% of all gastrointestinal tumors. Neuroendocrine tumors (NET) of the gastro-enteropancreatic system are also rare, representing about 2% of all gastrointestinal neoplasms. Pancreatic localization of NET is extremely uncommon-these tumors are only 1-5% of all pancreatic cancers. CASE PRESENTATION: We describe an unusual case with triple tumor localization-a gastric tumor, a formation in the pancreas, which involves the retroperitoneal space, and a uterine leiomyoma...
